Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a violating vehicle analysis device for detecting a violating vehicle such as an axle load violation or a speed violation and analyzing a vehicle which repeatedly violates.

[0002]

2. Description of the Related Art Conventionally, at toll gates such as highways,
The axle load is measured in order to prevent the entry of vehicles that exceed the specified axle load. As a result, a vehicle that exceeds the specified axle load will be warned on the spot to leave the expressway at the next tollgate, and the entire vehicle, driver and axle load violation data will be displayed in a silver salt photograph. It is supposed to be photographed.

Here, since the axle load violation is often repeated, the road administrator issues a warning to warn the owner of the vehicle that has violated a predetermined number of times or more. is doing.

Such a vehicle image taking apparatus which violates the axle load is constructed as shown in FIGS. 12 and 13, for example. FIG. 12 is a schematic diagram showing an example of a conventional violating vehicle imaging device 1. FIG. 13 is a schematic block diagram showing an electrical configuration of the violating vehicle photographing device 1 shown in FIG.

As shown in FIGS. 12 and 13, the vehicle image taking apparatus 1 which violates the axle load confirms the loading plate 3 for measuring the axle weight of the vehicle approaching the tollgate 2 and the position of the vehicle to be photographed. Fixed-position sensor 4 and camera 5 for photographing the vehicle
The printer 6 is provided inside the toll booth 2, the warning plate 7 is provided outside the toll booth 2, and the instruction control device 8.

[0006] The toll gate 2 is usually provided for an interchange such as an expressway or for a plurality of lanes lined up on the main line, and is constructed so that various vehicles can pass through in order to pay a toll. . Here, the toll booth 2 where the vehicle image capturing device 1 violating the axle load is installed is
In particular, it may be limited to only toll gates for the passage of large freight vehicles in which axial load violation is a problem.

The above-mentioned load plate 3 is arranged so as to substantially coincide with the road surface, and when a vehicle entering the toll booth 2 passes over it, the axle load of the axle positioned on the load plate 3 is increased. Is measured and the axial load data is output to the instruction control device 8 as shown in FIG. In the illustrated case, the loading plate 3 is arranged, for example, at a predetermined distance in front of the toll booth 2.

The fixed position sensor 4 outputs a vehicle detection signal when the violating vehicle reaches a position suitable for photographing when the axial load measured by the loading plate 3 exceeds a specified value. Is. The fixed position sensor 4 is, for example, a toll gate 2.
It is arranged at a position of a predetermined distance in front of.

The camera 5 is a camera using an ordinary silver salt film, and when the fixed position sensor 4 detects that the vehicle to be photographed (violating vehicle) is in a fixed position suitable for photographing, For example, the vehicle is arranged at a predetermined distance in front of the toll booth 2 and at a predetermined height so as to photograph the violating vehicle. Here, the camera 5 receives the axial load measured by the loading plate 3 from the instruction control device 8,
It is configured so that the axle weight, the date and time, and the place (toll gate name and lane name) are imprinted simultaneously.

The printer 6 has an instruction control device 8 when the axial load measured by the loading plate 3 is equal to or more than a specified value.
Based on the command, the violation data such as date and time, place and axle weight is printed.

The warning plate 7 is arranged at a position where the toll booth 2 is easy to see, and when the vehicle is in violation of axle load,
A message such as "excess of axle load" is displayed.

A vehicle image capturing apparatus 1 having an axial load violation having such a configuration
According to this, when a vehicle having an axle load violation enters the toll booth 2, the axles of the vehicle are sequentially placed on the loading plate 3 and the axle weight of each axle is measured.

When the axial load measured by the loading plate 3 is input to the instruction control device 8, the instruction control device 8 determines whether or not the axial load is equal to or greater than a specified value, and the specified value is determined. In the above case, the camera 5 captures an image of the entire offending vehicle based on the vehicle detection signal from the fixed position sensor 4. At the same time, the instruction control device 8 causes the printer 6 to print the axial load data from the loading plate 3 at that time, the date and time, and the location of the toll gate (hereinafter, violation data),
A warning plate 7 indicates that the axle load has been exceeded.

As a result, the staff member at the toll booth 2 hands over the violation data printed by the printer 6 to the driver,
Warn you to leave the highway at the next toll booth.

On the other hand, the film obtained by photographing the violating vehicle with the camera 5 is collected periodically (for example, once a month) and the camera 5 is loaded with a new film. After the collected film is developed, the quality of the image is judged by the negative. The negative portion in which the image is determined to be defective is excluded from the subsequent processing, for example, by punching holes.

Next, the good negative portions are sorted out, and the operator can read the data of the violating vehicle, that is, the registration number mark, the date and time of the violation, the axle weight, and the place by visually observing the negative. Then, data is input by a personal computer or the like. Then, the input data is collected at a plurality of toll gates and is processed by a large-scale computer or the like operated by a road administrator, thereby creating data of a violating vehicle. Then, the road administrator uses the large computer to analyze the vehicle that has violated the axle load a predetermined number of times or more from the data, and issues a warning letter to the owner of the vehicle to warn the violation. .

By the way, the negative is stored for a predetermined period, and a good negative portion is photo-printed, and this photo is also stored for a predetermined period.

For this reason, the labor and cost for maintenance of these negatives and photographs become enormous, and the reading and input of the data of the infringing vehicle by the negatives are performed by hand, which requires a great deal of labor. However, there is a problem that quick processing is difficult.

[0019]

Therefore, the inventor of the present invention
The violating vehicle is imaged by an image pickup means such as a CCD camera in place of the camera 5 using the silver salt film, and image data showing an image including a registration number mark of the violating vehicle is obtained. We have devised a violating vehicle analysis device that processes and reads all the registration numbers written on the registration number mark and processes the data of this registration number by a computer to analyze the vehicle that has violated a predetermined number of times.

According to this violating vehicle analysis device, it is not necessary to manually maintain and manage the negatives and photographs, and manually read and input the data of the violating vehicle from the negative. Can be automated.

Here, the registration number mark of the automobile will be described with reference to FIG. FIG. 14 is a schematic plan view showing a registration number mark.

As shown in FIG. 14, the registration number mark 9 is a serial number with a land transportation branch office name 9a on the upper part, a usage number 9b on the upper part, a hiragana character 9c on the left, and a large character in the center, as shown in FIG. 9d is described, and these constitute the registration number as a whole.

The Land Transport Office name 9a is in Kanji or Hiragana and consists of 1 to 4 characters. The name of the Land Transport Office in which the vehicle is registered is described. The application number 9b is currently composed of two-digit numbers and is defined according to the type of vehicle. The hiragana character 9c currently consists of hiragana or one letter of the alphabet. The sequence number 9d consists of four large numbers, but if the number of digits is small, instead of "0", "."
Is used.

However, even though the image processing technology has advanced remarkably, all registration numbers (Land Transport Bureau name 9
a, application number 9b, hiragana character 9c, serial number 9d)
Is impossible to read.

Therefore, the above-described fully-automated violating vehicle analysis device inevitably causes the owner of a non-violating vehicle to erroneously give a warning of the violation.
It is unacceptable to give false warnings, even if the false warnings are unlikely.

The present invention has been made in view of such circumstances, and the number of steps for analyzing a vehicle that repeatedly violates can be significantly reduced, and the reliability of the analysis can be sufficiently ensured. It is an object of the present invention to provide an analyzing device for a violating vehicle that is capable of doing so.

[Means for Solving the Problems ]
Therefore, the violating vehicle analysis device according to the first aspect of the present invention detects a violating vehicle and outputs a detection signal to the detecting means, and images the violating vehicle in response to the detection signal from the detecting means. An image pickup means for obtaining image data showing an image including a registration number mark of the infringing vehicle, and a registration number written on the registration number mark of the infringing vehicle based on the image data obtained by the image pickup means. An image processing unit for reading a partial number that is a part and obtaining partial number data indicating the partial number, and the image data and the partial number data corresponding to the image data are associated with each other and stored. Displaying means for storing in the means, selecting means for selecting predetermined image data from the image data stored in the storing means, and an image represented by the image data selected by the selecting means And an additional number indicating the additional number that is a part other than the partial number among the registration numbers displayed on the registration number mark of the infringing vehicle read from the image with respect to each display image displayed on the display unit. Additional data input means for an operator to input number data, additional writing means for storing the additional number data from the additional data input means in the storage means in association with corresponding image data, and the storage means. Of the stored image data, the determination means for determining whether or not the number of pieces of image data associated with the same partial number data and the additional number data is a predetermined number or more; Output means for outputting data relating to the infringing vehicle when it is determined that there is the violating vehicle, and the selection means includes the image data stored in the storage means. Regarding the image data associated with the same partial number data, in consideration of the additional number data, when there is a possibility that the image data of the same vehicle will be a predetermined number or more, the related additional number of the image data Image data for which no data exists is selected.

According to the first aspect, the image processing means reads the partial number, which is a part of the registration number, based on the image data of the violating vehicle imaged by the image pickup means,
The partial number and the corresponding image data are associated with each other and stored in the storage means.

Then, regarding the image data associated with the same partial number data among the image data stored in the storage means, the number of image data of the same vehicle may be a predetermined number or more in consideration of the additional number data. If there is
Of the image data, image data for which no related additional number data exists is selected by the selection unit. That is,
Regarding the image data to which the additional number data is not yet associated (that is, the additional number data is not yet input), the additional number of the vehicle can be any number, and the additional number data is already associated ( That is, regarding the image data (for which the additional number data has already been input), it is assumed that the additional number of the vehicle has been decided, and the possibility that the additional numbers match will be taken into consideration and the images will be associated with the same partial number data. Regarding the image data, when there is a possibility that the number of image data of the same vehicle will be greater than or equal to a predetermined number, the selecting unit 25 selects the image data for which the related additional number data does not exist. In other words, in consideration of the additional number data, among the image data corresponding to the vehicle that may have violated a predetermined number of times or more, the image data for which the additional number data has not been input is selected by the selection unit. .

Then, the vehicle image represented by the image data selected by the selection unit is displayed by the display means. The operator inputs the additional number data indicating the additional number read from the image displayed by the display means by the additional data input means. The additional number data is stored in the storage unit in association with the corresponding image data by the additional writing unit.

By the above operation, the image data for which the additional number data has not yet been input among the image data corresponding to the vehicle that may have violated a predetermined number of times is picked up by the selection unit and displayed as an image on the display unit. Then, with respect to the image data, the additional number data is input by the additional data input unit, and the additional number data is associated with the additional writing unit. Therefore, the image data corresponding to the vehicle that may have violated a predetermined number of times is associated with the additional number data read and input by the operator from the image.

The image data stored in the storage means are associated with the same partial number data and additional number data (that is, the same registration number (that is, the same registration number).
Whether the number of pieces of image data (associated with the same vehicle) is equal to or greater than a predetermined number is determined by the determination means, and when the determination means determines that the number is equal to or more than the predetermined number (that is, the same vehicle is performed a predetermined number of times). In the case of the above violation), the output means outputs the data regarding the infringing vehicle. The data regarding the infringing vehicle is not particularly limited, but may be, for example, partial number data and image data of the infringing vehicle. The data output from the output unit is printed on a sheet of paper, or stored in an auxiliary storage unit different from the storage unit, and can be appropriately processed by another processing device or the like. It can be used as data for preparing warning letters.

Therefore, according to the first aspect, it is not necessary to manually maintain and manage the negatives and photographs, and all the registration numbers and the like of all the vehicles photographed (all the violating vehicles) as in the prior art. Only the image of the vehicle that may have violated more than a predetermined number of times and the additional number data has not been input yet is displayed by the display means without manually inputting the data of 1. By visually observing and inputting only the additional number related thereto, the vehicle which has violated a predetermined number of times or more is automatically analyzed. The reading accuracy is remarkably improved when a part of the registration number is read by the image processing means compared to when the image processing means reads the entire registration number from the image data. The image data can be appropriately selected.

Therefore, according to the first aspect, it is not necessary to manually maintain and manage the negatives and photographs, and the number of data input steps is significantly reduced, and the operator can obtain the image by the image pickup means. Instead of visually observing all the images, only the images of vehicles that may have violated a certain number of times and for which additional number data has not been entered have to be visually inspected. There are also few steps. As a result, the number of steps for analyzing a vehicle that repeatedly violates is significantly reduced. In addition, since vehicles that have violated more than a specified number of times are automatically analyzed based on some numbers with extremely high reading accuracy and the additional numbers confirmed by the operator visually observing the image of the vehicle, the number of vehicles that repeatedly violate the vehicle is analyzed. It is possible to secure sufficient reliability of analysis.

As described above, according to the first aspect, it is possible to greatly reduce the number of steps for analyzing a vehicle that repeatedly violates, it is possible to perform a quick process, and the reliability of the analysis is improved. Can be sufficiently secured.

[0050] In the prior SL first aspect, since the operator need not be visually confirmed again for temporarily image input visually to add number data, more preferred.
In addition, in the first aspect, since the image data of the vehicle that has violated a predetermined number of times or more is associated not only with the partial number data but also with the additional number data, for example, when the warning letter is created, the additional number data is added. Is also preferable because it can also be used.

The violating vehicle analysis device according to the second aspect of the present invention comprises a plurality of detection units respectively provided at a plurality of places and one analysis unit to which data from each of the detection units is inputted. It is a thing. Then, each of the detection units detects a violating vehicle and outputs a detection signal, and images the violating vehicle in response to the detection signal from the detecting means, and registers the registration number of the violating vehicle. And an image pickup unit that obtains image data indicating an image including. In addition, the analysis unit reads a partial number, which is a part of the registration number written on the registration number mark of the offending vehicle, based on the image data obtained by the imaging unit of each of the detection units. And image writing means for obtaining partial number data indicating the partial number, and writing means for storing the partial number data and the image data corresponding to the partial number data in the storage means in association with each other. Selecting means for selecting predetermined image data among the image data stored in the storage means, display means for displaying an image represented by the image data selected by the selecting means, and display means for displaying on the display means. For each image, an additional number data showing the additional number that is the part other than the partial number among the registration numbers written on the registration number mark of the infringing vehicle read from the image. Stored in the storage means, additional data input means for an operator to input, additional write means for storing the additional number data from the additional data input means in the storage means in association with the corresponding image data. Determining unit that determines whether or not the number of image data associated with the same partial number data and the additional number data among the image data is a predetermined number or more; Output means for outputting data relating to the infringing vehicle when the determination is made, and the selecting means relates to image data associated with the same partial number data among the image data stored in the storage means. In consideration of the additional number data, if there is a possibility that the number of image data of the same vehicle exceeds a predetermined number, the related additional It is to select the image data numbered data does not exist.

The second mode is a specific example of the first mode, in which the violation data about the violating vehicle detected by the detection units respectively provided at a plurality of places are:
It clearly shows an example sent to one analysis unit. In the second aspect, the data detected by the plurality of detection units is sent to one analysis unit, so that the data is intensively analyzed by this one analysis unit. Therefore, a worker is required only for the analysis unit, which saves labor and greatly improves work efficiency.

In the second aspect, the analysis unit has the image processing means, but in the first aspect, instead, the image processing means may be provided in each detection unit. Good.

A violating vehicle analyzing device according to a third aspect of the present invention is the violating vehicle analyzing device according to the first or second aspect, wherein the selecting means is newly stored in the storage means by the writing means. Regarding the partial number data associated with the image data, regarding the image data associated with the partial number data among the image data stored in the storage unit, the image of the same vehicle in consideration of the additional number data. When there is a possibility that the number of data is more than a predetermined number, the selection is performed by selecting the image data having no related additional number data among the image data.

In the third aspect, since the image data is selected with respect to the partial number data associated with the image data newly stored by the writing means, the image data can be efficiently selected. . However, in the first and second aspects, the selection unit may perform the selection for all the partial number data stored in the storage unit, for example, every predetermined time.

A violating vehicle analyzing device according to a fourth aspect of the present invention is the violating vehicle analyzing device according to the first to third aspects, wherein the determining means is newly stored in the storage means by the additional writing means. With respect to the partial number data associated with the additional number data, the number of image data associated with the partial number data and the same additional number data among the image data stored in the storage unit is equal to or more than a predetermined number. The determination is performed by determining whether or not there is any.

In the fourth mode, the additional writing means makes a determination on the partial number data associated with the newly stored additional number data, so that the determination can be made efficiently. However, the first to third
In this aspect, the determination means, for example, every predetermined time,
The determination may be performed on all the partial number data stored in the storage means.

[0058] violation vehicle analysis system according to the fifth aspect of the present invention, in violation vehicle analysis system according to the first to fourth one embodiment, when the output unit outputs the data, related to the violation vehicle The image data and the partial number data and the additional number data associated with the image data are deleted from the storage unit.

In the fifth aspect, when the output means outputs the data relating to the violating vehicle, the data relating to the violating vehicle is deleted by the deleting means, so that the violating vehicle was violated a predetermined number of times or more. The data can be removed from the object of the subsequent analysis, the amount of data stored in the storage means can be reduced, and the storage capacity of the storage means can be effectively used.

A violating vehicle analysis device according to a sixth aspect of the present invention detects a violating vehicle and outputs a detection signal to the violating vehicle, and images the violating vehicle in response to the detection signal from the detecting means. Based on the image data obtained by the image capturing means and the image data obtained by the image capturing means, the registration number written on the registration number mark of the violating vehicle. An image processing unit that reads a partial number that is a part of the registration number and an additional number that is another part of the registration number, and obtains partial number data indicating the partial number and additional number data indicating the additional number, By associating the image data and the partial number data and the additional number data corresponding to the image data with each other,
Writing means to be stored in the storage means, selection means for selecting predetermined image data from the image data stored in the storage means, and display means for displaying an image represented by the image data selected by the selection means. And, the additional number data corresponding to the image stored in the storage means is added to the additional number of the registration number written on the registration number mark of the infringing vehicle read from each image displayed on the display means. If they do not match, the operator outputs an addition / correction command for adding and correcting the additional number data, and if they match, the operator confirms the match. Addition / correction to output commands
Confirmation operation means, addition / correction writing means for adding and correcting the additional data to / from the data stored in the storage means in response to the addition / correction command, and the addition / correction writing means In response to the addition or correction or in response to the match confirmation command, the confirmation information setting means for setting confirmation information for the corresponding additional number data and the image data stored in the storage means are the same. Determining means for determining whether or not the number of image data associated with the partial number data and the additional number data for which the confirmation information is set is a predetermined number or more; Output means for outputting data relating to the infringing vehicle when the determination is made, and the selecting means is the same partial number of the image data stored in the storage means. Regarding the image data associated with the image data, considering the additional number data in which the confirmation information is set, if there is a possibility that the image data of the same vehicle will be a predetermined number or more, The image data for which the confirmation information to be set is not set is selected.

According to the sixth aspect, the partial number which is a part of the registration number and the additional number which is the other part of the registration number are imaged based on the image data of the violating vehicle imaged by the image pickup means. The partial number, the additional number, and the corresponding image data read by the processing unit are associated with each other and stored in the storage unit.

Then, regarding the image data associated with the same partial number data among the image data stored in the storage means, the image data of the same vehicle is taken into consideration in consideration of the additional number data for which confirmation information is set. When there is a possibility that the number is greater than or equal to a predetermined number, the selecting unit selects the image data for which the related confirmation information is not set among the image data. That is, the additional number of the vehicle can be any number for the image data that is not associated with the additional number data for which the confirmation information is set (that is, addition, correction, or confirmation of the additional number data has not been completed yet). In addition, regarding the image data to which the additional number data for which the confirmation information is already set is associated (that is, addition, correction or confirmation of the additional number data has already been completed), the additional number of the vehicle has been confirmed. As for the image data associated with the same partial number data, if there is a possibility that the number of image data of the same vehicle exceeds a predetermined number, the image The image data for which the related confirmation information is not set is selected by the selection unit. In other words, in consideration of the additional number data that has been added, corrected or confirmed, of the image data corresponding to the vehicle that may have violated a predetermined number of times or more, the addition, correction or confirmation of the additional number data is still completed. The image data that has not been selected is selected by the selection unit.

Then, the vehicle image represented by the image data selected by the selection unit is displayed by the display means. If the additional number read from the image displayed by this display means does not match the additional number data corresponding to the image stored in the storage means (that is,
If the additional number can not be read by the image processing means or is incorrect), an addition / correction command for operating the addition / correction / confirmation operation means to add and correct the additional number data is issued. In addition to outputting, if both match (that is, if the reading of the additional number by the image processing means was correct), the addition /
The correction / confirmation operation means is operated to output a coincidence confirmation command. In response to the addition / correction command, the addition / correction writing unit adds or corrects the additional data to / from the data stored in the storage unit. And
In response to the addition or correction by the addition / correction writing means or in response to the match confirmation command, confirmation information is set by the confirmation information setting means for the corresponding additional number data. Therefore, the additional number data in which the confirmation information is set means that the additional number is in the correct state after the operator visually checks the image of the vehicle.

By the above operation, the image data for which the addition, correction and confirmation of the additional number data have not been completed among the image data corresponding to the vehicle which may have violated a predetermined number of times are picked up by the selection unit, The image data is displayed as an image, and the image data is added, corrected or confirmed by the addition / correction / confirmation operation means and the addition / correction writing means, and the confirmation information is set by the confirmation information setting means. . Therefore, the image data corresponding to the vehicle that may have violated the predetermined number of times is associated with the additional number data read, added, corrected or confirmed by the operator from the image.

Then, among the image data stored in the storage means, the same partial number data and the additional number data in which the confirmation information is set are associated (that is, the additional number is the same confirmed registration number). When the number of pieces of image data (that is, associated with the same vehicle) is greater than or equal to a predetermined number, the determination unit determines, and when the determination unit determines that the number is greater than or equal to the predetermined number (that is,
When the same vehicle violates a predetermined number of times or more), the output means outputs data regarding the violating vehicle. The data regarding the infringing vehicle is not particularly limited, but may be, for example, partial number data and image data of the infringing vehicle. The data output from the output unit is printed on a sheet of paper, or stored in an auxiliary storage unit different from the storage unit, and can be appropriately processed by another processing device or the like. It can be used as data for preparing warning letters.

Therefore, according to the sixth aspect, it is not necessary to manually maintain and manage the negatives and photographs, and all the registration numbers and the like of all vehicles photographed conventionally (all violation vehicles) are eliminated. Without manually inputting the data of the above, only the image of the vehicle that may have violated a predetermined number of times and the additional number data has not yet been added, corrected and confirmed is displayed by the display means, Only by the operator visually observing this image and adding, correcting or confirming an additional number related thereto, the vehicle which has violated a predetermined number of times or more is automatically analyzed. The reading accuracy is remarkably improved when a part of the registration number is read by the image processing means compared to when the image processing means reads the entire registration number from the image data. The image data can be appropriately selected.

Therefore, according to the sixth aspect, it is not necessary to manually maintain and manage the negatives and photographs, and the number of data input steps is significantly reduced. Moreover, the operator can obtain the image by the image pickup means. Instead of looking at all the images, only the images of the vehicle that may have violated a predetermined number of times and the additional number data has not yet been added, corrected or confirmed, so The number of steps required to visually check the image is small. As a result, the number of steps for analyzing a vehicle that repeatedly violates is significantly reduced. In addition, since vehicles that have violated more than a specified number of times are automatically analyzed based on some numbers with extremely high reading accuracy and the additional numbers confirmed by the operator visually observing the image of the vehicle, the number of vehicles that repeatedly violate the vehicle is analyzed. It is possible to secure sufficient reliability of analysis.

As described above, according to the sixth aspect, it is possible to greatly reduce the number of steps for analyzing a vehicle that repeatedly violates, it is possible to perform a quick process, and the reliability of the analysis is improved. Can be sufficiently secured.

[0069] In the prior SL sixth aspect, additional additional number data visually worker once, since the image subjected to correction or confirmation visually to need not be confirmed again, more preferred. Further, in the sixth aspect, the image data of the vehicle that has violated a predetermined number of times or more is associated not only with the partial number data but also with the confirmed additional number data. It is preferable because the additional number data can be used.

[0070] Although the sixth aspect is similar to the first embodiment basically, in the first embodiment, when the image of the vehicle is displayed by the display means, with respect to the image While it was necessary to input the additional number data without fail, in the sixth aspect, when the image of the vehicle is displayed by the display means, it is necessary to add, correct or confirm the additional number with respect to the image. Since this is good, the labor of the operator is further reduced.

The violating vehicle analysis device according to the seventh aspect of the present invention comprises a plurality of detection units respectively provided at a plurality of places and one analysis unit to which data from each of the detection units is inputted. It is a thing. Then, each of the detection units detects a violating vehicle and outputs a detection signal, and images the violating vehicle in response to the detection signal from the detecting means, and registers the registration number of the violating vehicle. And an image pickup unit that obtains image data indicating an image including. In addition, the analysis unit, based on the image data obtained by the imaging unit of each of the detection unit, a partial number which is a part of the registration number written in the registration number mark of the offending vehicle and An image processing unit that reads an additional number, which is another part of the registration number, to obtain partial number data indicating the partial number and additional number data indicating the additional number, and corresponds to the image data and the image data. Writing means for causing the storage means to store the partial number data and the additional number data in association with each other; selecting means for selecting predetermined image data from the image data stored in the storage means; Display means for displaying an image represented by the image data selected by the selecting means, and a registration number mark of a violating vehicle read from each image displayed on the display means. When the additional number data corresponding to the image stored in the storage unit does not match the additional number of the registered number, the additional number data is added and corrected by the operator's operation. Output addition / correction commands for
When the two match, the addition / correction / confirmation operation means for outputting a coincidence confirmation command by the operator's operation and the data stored in the storage means in response to the addition / correction command The addition / correction writing means for adding and correcting the additional data, and the corresponding additional number data in response to the addition or correction by the addition / correction writing means or in response to the match confirmation command. The number of pieces of image data associated with the confirmation information setting means for setting confirmation information and the same partial number data among the image data stored in the storage means and the additional number data with the confirmation information set is Determination means for determining whether or not the number is a predetermined number or more, and output means for outputting data regarding the violating vehicle when the determination means determines that the number is a predetermined number or more. Of the image data stored in the storage unit, the selecting unit considers the image data associated with the same partial number data in consideration of the additional number data in which the confirmation information is set. If there is a possibility that the image data of the vehicle will exceed the predetermined number,
Image data for which related confirmation information is not set is selected from the image data.

The seventh aspect is a specific example of the sixth aspect, in which the violation data about the violating vehicle detected by the detection units provided at a plurality of places respectively,
It clearly shows an example sent to one analysis unit. In the seventh aspect, the data detected by the plurality of detection units is sent to one analysis unit, so that the data is intensively analyzed by this one analysis unit. Therefore, a worker is required only for the analysis unit, which saves labor and greatly improves work efficiency.

FIG. 3 is a diagram showing an example of the structure of data used in the violating vehicle analysis device according to the present embodiment, and FIG. 3A is a diagram showing an example of the structure of data received by the receiving unit 21, FIG. b) is a diagram showing an example of a structure of data stored in the storage unit 24.

Violation vehicle analysis device 10 according to the present embodiment
Is configured to detect and analyze an axle weight violation vehicle as a violation vehicle. As shown in FIG. 1, a plurality of detection units 11 and a single analysis unit 20 respectively provided at a plurality of locations are provided. It is configured. However, in the present invention, only one detection unit 11 may be used depending on the application.

Each detection unit 11 is installed, for example, in each lane or a predetermined lane of a tollgate such as an expressway. The analysis unit 20 may be installed in a toll booth office or the like, or may be installed in a management center or the like provided in one place for a plurality of toll booths such as one expressway. Good. As a result, the analysis of the violating vehicle in each detection unit 11 can be centrally managed at the tollgate office, the management center, etc., and the labor can be saved.

As shown in FIG. 1, each detection unit 11 comprises a detection unit 12, a violation data output unit 13, an image pickup unit 14 such as a CCD camera, and a transmission unit 15.

The detecting unit 12 measures the axle load of the vehicle traveling in the lane, and when the axle load value exceeds a specified value, determines that the axle load is violated and outputs a detection signal.

The violating data output unit 13 includes the detecting unit 12
When the axis load violation is detected, it outputs the date and time (for example, tollgate name and lane name) and, if necessary, the axis load value as the violation data.

In response to the detection signal from the detection unit 12, the image pickup unit 14 picks up an image of the offending vehicle and obtains image data showing an image including the registration number mark of the offending vehicle.

The transmitting section 15 includes a violation data output section 13
Violating data from and image data from the imaging unit 14,
The receiving unit 2 provided on the analysis unit 20 side is encoded into a format suitable for transmission, and using an appropriate means, for example, a general public line or a dedicated line, or wirelessly.
Send to 1.

As a concrete construction of such a detection unit 11, for example, in the conventional violating vehicle photographing device shown in FIGS. 12 and 13, the silver-salt film camera 5 is replaced with a CCD camera or the like. It is possible to adopt a configuration in which the transmitting unit 15 is added.

On the other hand, the analysis unit 20, as shown in FIG. 1, has a receiving section 21, an image processing section 22, and a writing section 23.
The storage unit 24, the selection unit 25, the display unit 26, the alarm unit 26a, the operation unit 27, the output unit 28, and the deletion unit 29.
And are equipped with.

The reception section 21 receives the violation data and the image data transmitted from the transmission section 15 of each detection unit 11, restores them to the original format by decoding, and sends them to the image processing section 22 and the writing section 23. . In this embodiment,
The structure of the data received by the reception unit 21 is, for example, as shown in FIG. 3A for one violation of one violating vehicle (that is, for one imaging). Although not shown in FIG. 3A, data such as axle load value is added as necessary as part of the violating vehicle data.

Based on the image data from the receiving unit 21, the image processing unit 22 reads a partial number, which is a part of the registration number written on the registration number mark of the offending vehicle, by pattern recognition, and Part number data indicating a part number is obtained. In the present embodiment, a 4-digit serial number (reference numeral 9d in FIG. 14) is used as the partial number.

The writing section 23 stores the image data and the violation data from the receiving section 21 and the partial number data corresponding to them obtained by the image processing section 22 in the storage section 24 in association with each other.

The storage unit 24 stores the image data written by the writing unit 23 and the partial number data and the violation data associated with the image data. In the present embodiment, the structure of the data stored in the storage unit 24 is as shown in FIG.
It is as shown in (b). For convenience of explanation, FIG.
The data (partial number data, date data, time data, location data, image data) in one line in (b) are associated with each other, and are referred to as records for convenience of description. Therefore, the data of one record consists of partial number data, date data, time data, place data, and image data associated with each other for one violation of one violating vehicle. Although not shown in FIG. 3B, data such as axle load value is added to the data of one record as a part of the violating vehicle data, if necessary. Further, in the present embodiment, each record is sorted by partial number data (serial number in the present embodiment) in order to facilitate various processes described later.

When the number of pieces of image data associated with the same partial number data among the pieces of image data stored in the storage portion 24 is a predetermined number or more, the selecting section 25 outputs the predetermined number of images or more. Select data. In other words, when the number of records having the same partial number data is a predetermined number or more, each image data included in the predetermined number or more of records is selected. The predetermined number is appropriately determined depending on how many times or more the vehicle that has violated is repeatedly analyzed.
In the following description, it is assumed that the violated vehicle is analyzed three times or more. Therefore, in the following description, the predetermined number is "3". For example, when the data shown in FIG. 3B is stored in the storage unit 24, the number of pieces of image data of the records R1, R2, and R3 having the serial number “... 1” is three. The selecting unit 25 selects three pieces of image data of records R1, R2 and R3.

In the present embodiment, the selection unit 25 stores the partial number data associated with the image data newly stored in the storage unit 24 by the writing unit 23 with respect to the storage unit 24.
The selection is performed by determining whether or not the number of pieces of image data associated with the partial number data among the image data stored in is equal to or larger than a predetermined number. In other words, the writing unit 23 newly adds a record to the storage unit 24.
When the number of records having the same partial number data as the partial number data of the record is equal to or more than a predetermined number, the selecting unit 25 determines whether the number of records is equal to or more than the predetermined number. Each image data included in the record of is selected. For example, when the data stored in the storage unit 24 becomes as shown in FIG. 3B by newly storing the record R3 in the storage unit 24, the serial number “... 1” of the record R3. Since the number of image data of the records R1, R2, R3 having the same serial number “... 1” as “3” is 3, the selection unit 25 causes the records R1, R2
Three image data of 2 and R3 will be selected.
In this case, since the image data is selected with respect to the partial number data associated with the image data newly stored by the writing unit 23, the image data can be efficiently selected. However, the selection means is, for example,
The selection may be performed for all the partial number data stored in the storage unit 24 every predetermined time.

The display section 26 displays each image indicated by each image data selected by the selection section 25, and if necessary, partial number data and violation data. In this case, each image may be displayed on the same screen at the same time, or may be sequentially displayed on the screen.

When the selecting unit 25 selects image data, the alarm unit 26a issues an alarm indicating that the image data has been selected.
This alarm may be any alarm such as sounding an alarm sound or displaying an alarm on the screen of the display unit 26.

When the number of images of the same vehicle having the same registration number mark among the images displayed on the display unit 26 is a predetermined number, for example, three or more, the operation unit 27 is operated by the operator. The confirmation command is output to the output unit 28.

The output unit 28 outputs data relating to the offending vehicle in response to the confirmation command from the operation unit 27. This output is, for example, a printout by a printer, recording to a large-capacity auxiliary storage medium such as a magneto-optical disk or a removable hard disk for direct transmission of data to a large-scale computer system for issuing a warning, direct transmission, etc. Is.

When the output unit 28 outputs the data, the deleting unit 29 deletes the record relating to the offending vehicle from the storage unit 24. In addition, the deletion unit 29 checks the date data of each record stored in the storage unit 24 periodically or in response to a command from the worker, and checks the date data for a predetermined period, for example, three years or more. , Delete the record.

The above-mentioned respective elements 23, 25, 29, etc. are actually realized by the operation of the computer according to the program.

Next, an example of the operation of the violating vehicle analysis device 10 according to the present embodiment will be described with reference to the flowchart shown in FIG.

First, the detection section 12 of the detection unit 11 detects a vehicle in violation of axle load and outputs a detection signal (step S).
1) and in response to this detection signal, the image capturing unit 14 captures an image of the infringing vehicle to obtain image data showing an image including the registration number mark of the infringing vehicle, and the infringing data output unit 1
3 outputs the violation data (step S2). As a result, the transmission unit 15 transmits these image data and violation data to the reception unit 21 of the analysis unit 20 (step S3).

On the other hand, the receiver 21 of the analysis unit 20 receives the image data and the violation data (see FIG. 3A) from the transmitter 15 of the detection unit 11 (step S4).

The image processing unit 22 receives the image data from the receiving unit 21, and based on this image data, a partial number (a book number) which is a part of the registration number written on the registration number mark of the offending vehicle. In the embodiment, a 4-digit serial number is read by pattern recognition, and the serial number (for example, ".
.. "1") is obtained (step S)
5).

Next, the writing unit 23 stores the image data and the violation data from the receiving unit 21 and the partial number data corresponding to them obtained by the image processing unit 22 in the storage unit 24 in association with each other. (Step S6). In this step S6, for example, the record R in FIG.
3 is newly stored in the storage unit 24, and the data stored in the storage unit 24 becomes as shown in FIG.

When the illegal vehicle is detected, the writing of the data relating to the illegal vehicle into the storage unit 24 is completed.

After that, the selecting unit 25 selects the partial number of the image data stored in the storage unit 24 with respect to the partial number data associated with the image data newly stored in the storage unit 24 in step S6. It is determined whether the number of pieces of image data associated with the data is three or more (step S7). In other words, the selection unit 25 determines whether the number of records having the same partial number data as the partial number data of the record newly stored in the storage unit 24 in step S6 is three or more. . If NO, the image data associated with the partial number data is not the image data corresponding to the vehicle that may have violated three or more times, so the process returns to step S1 without selecting the image data. .

On the other hand, if YES is determined in step S7, the image data associated with the partial number data is the image data corresponding to the vehicle that may have violated three or more times. Selection by the unit 25 (step S8) When each image data is selected by the selection unit 25, an alarm indicating that the alarm unit 26a is selected is issued (step S8).
9) Then, the display unit 26 displays the image (the image including the registration number mark of the infringing vehicle) indicated by each image data selected in step S8 (step S10), and waits for confirmation by the operator.

The operator observes the display unit 26 in response to the alarm generated by the alarm unit 26a, and visually observes each image (especially the registration number mark) displayed on the display unit 26 to confirm the violation indicated by each image. Regarding the vehicle, it is determined whether or not there are three or more images of the same vehicle, and when there are three or more images, a confirmation operation is performed on the operation unit 27 (including an operation of selecting the three or more images). )I do. As a result, the operation unit 27 outputs a confirmation command to the output unit 28, and proceeds from step S11 to step S12.

When the number of images of the same vehicle is two or less for the violating vehicle indicated by each image, the operator performs an unconfirmed operation on the operation unit 27. As a result, the process returns from step S11 to step S1.

When a confirmation command is output from the operation unit 27,
In response to the confirmation command, the output unit 28 outputs data regarding the infringing vehicle (data corresponding to the image selected by the operator indicated by the confirmation instruction), for example, three or more records regarding the infringing vehicle. (Step S1
2).

When the output unit 28 outputs the data regarding the violating vehicle, the deleting unit 29 receives the data and stores the record corresponding to the image selected by the operator indicated by the confirmation command. It is deleted from the section 24 (step S13), and the process returns to step S1.

Although not shown in the flow chart shown in FIG. 2, the deletion unit 29, as described above, periodically deletes the date of each record stored in the storage unit 24 or in response to the operator's instruction. The data is checked, and the record is deleted when a predetermined period, for example, three years or more has passed from this date.

According to the violating vehicle analysis device of the present embodiment described above, it is not necessary to manually maintain and manage negatives and photographs, and all vehicles photographed conventionally (all violating vehicles) Only the image of the vehicle that may have violated a predetermined number of times is displayed on the display unit 26 without manually inputting all the data such as the registration number. For example, the operator can visually check the image. Then, the vehicle that has violated a predetermined number of times or more can be confirmed and grasped. The reading accuracy is significantly improved when a part of the registration number is read by the image processing unit 22 compared to when the image processing unit 22 reads the entire registration number from the image data. Therefore, a vehicle that may have violated a predetermined number of times or more. It is possible to appropriately select the image data. In particular, in the present embodiment, since the serial number represented by a large character is used as a partial number, the reading by the image processing means can be performed very accurately, which is preferable. However, the partial number is not limited to the serial number, and may be a combination of the serial number and the application number, for example.

Therefore, according to the present embodiment, it is not necessary to manually maintain and manage the negatives and photographs, and the number of data input steps is significantly reduced. Since all the images are not visually inspected, but only the images of the vehicle that may have violated a predetermined number of times or more are visually inspected, the number of steps for visually confirming the images is small. As a result, the number of steps for analyzing a vehicle that repeatedly violates is significantly reduced. Further, finally, the operator visually confirms the image of the vehicle, so that it is possible to sufficiently secure the reliability of the analysis of the vehicle that repeatedly violates.

As described above, according to the present embodiment, it is possible to greatly reduce the number of steps for analyzing a vehicle that repeatedly violates, and it is possible to perform a quick process.
The reliability of the analysis can be sufficiently ensured.

In this embodiment, the alarm unit 26a,
Although the output unit 28, the deletion unit 29, and the like are provided, these are not necessarily required.

FIG. 4B is a diagram showing an example of the structure of data stored in the storage unit 44.

Violation vehicle analysis device 30 according to the present embodiment
Is also configured to detect and analyze an axle weight violation vehicle as a violation vehicle. As shown in FIG. 4, a plurality of detection units 31 and a single analysis unit 40 respectively provided at a plurality of locations are provided. It is configured. However, in the present invention, only one detection unit 31 may be used depending on the application.

Each of the detection units 31 has the same structure as the detection unit 11 in the violating vehicle analysis device 10 shown in FIG. 1, and the description thereof will be omitted.

The analysis unit 40, as shown in FIG.
The receiving unit 41, the image processing unit 42, the writing unit 43, the storage unit 44, the selection unit 45, the display unit 46, and the alarm unit 46.
a, an operation unit 47, an output unit 48, a deletion unit 49, an additional writing unit 50, and a determination unit 51.

The reception section 41 receives the violation data and the image data transmitted from the transmission section 15 of each detection unit 31, restores them to the original format by decoding, and sends them to the image processing section 42 and the writing section 43. . In this embodiment,
The structure of the data received by the reception unit 41 is, for example, as shown in FIG. 6A for one violation of one violating vehicle (that is, for one imaging). Although not shown in FIG. 6A, data such as an axle load value is added as necessary as part of the violating vehicle data.

Based on the image data from the receiving unit 41, the image processing unit 42 reads a partial number, which is a part of the registration number written in the registration number mark of the offending vehicle, by pattern recognition, and Part number data indicating a part number is obtained. In the present embodiment, a 4-digit serial number (reference numeral 9d in FIG. 14) is used as the partial number.

The writing section 43 stores the image data and the violation data from the receiving section 41 and the partial number data corresponding to them obtained by the image processing section 42 in the storage section 44 in association with each other.

The storage unit 44 stores the image data written by the writing unit 43, the partial number data and the violation data associated therewith, and the additional number data associated therewith. The additional number data is a part other than the partial number in the registration number written on the registration number mark. In the present embodiment, since the serial number is used as the partial number, the additional number data is composed of the usage number data, the hiragana character data and the Land Transport Office name data. In the present embodiment, the storage unit 44
The structure of the data stored in is shown in FIG. 6 (b). For convenience of explanation, each data of one row in FIG. 6B (partial number data, date data, time data,
The location data, the image data, the usage number data, the hiragana character data, and the Land Transport Office name data) are associated with each other, and are referred to as records for convenience of description. Therefore, the data of one record includes partial number data, date data, time data, location data, image data, application number data, hiragana character data, and land transportation bureau that are associated with each other for one violation of one violating vehicle. It consists of name data. In FIG. 6B, the mark "!"
Indicates that data has not yet been input and is not stored in the storage unit 44. Although not shown in FIG. 6B, data such as axle load value is added to the data of one record as a part of the offending vehicle data, if necessary.
Further, in the present embodiment, each record is sorted by partial number data (serial number in the present embodiment) in order to facilitate various processes described later.

Regarding the image data associated with the same partial number data among the image data stored in the storage unit 44, the selecting unit 45 determines the image data of the same vehicle in consideration of the additional number data. When there is a possibility that the number will be more than the number, the image data for which the related additional number data does not exist is selected from the image data. That is, the additional number data is not yet associated (ie,
For records in which the additional number data is "!", The additional number data can be any number, and the additional number data is already associated (that is, the additional number data is "!"). Absent)
Regarding the record, assuming that the additional number data is fixed, considering the possibility of matching of the additional number data, regarding the records having the same partial number data, the number of records of the same vehicle may exceed the predetermined number. If there is a property, the additional number data in the record is “!”.
The image data of the record that is selected is selected by the selection unit 45. In other words, in consideration of the additional number data, the image data corresponding to the vehicle that may have violated a predetermined number of times or more may be selected by the selecting unit 45 as the image data for which the additional number data has not been input. Become. The predetermined number is appropriately determined depending on how many times or more the vehicle that has violated is repeatedly analyzed. In the following description, it is assumed that the violated vehicle is analyzed three times or more. Therefore, in the following description, the predetermined number is "3". For example, when the data as shown in FIG. 6B is stored in the storage unit 44, regarding the records R11, R12, R13, R14 having the serial number “... 1”, the records R11, R13, R14 Since the additional number data may match, there may be three or more records for the same vehicle. Therefore, the records R11 and R1
The image data of the record R14 in which the additional number data is “!” Out of R3 and R14 is selected by the selection unit 45.

In the present embodiment, the selection unit 45 stores the partial number data associated with the image data newly stored in the storage unit 44 by the writing unit 43.
Regarding the image data associated with the partial number data among the image data stored in, if there is a possibility that the number of image data of the same vehicle will be more than a predetermined number in consideration of the additional number data, The selection is performed by selecting the image data in which the related additional number data does not exist among the data. In other words, when a new record is stored in the storage unit 44 by the writing unit 43, the selecting unit 45 determines whether the additional number data matches the record having the same partial number data as the partial number data of the record. In consideration of the possibility, when there is a possibility that the number of records of the same vehicle will be a predetermined number or more, the image data of the record in which the additional number data is “!” Is selected from the records. For example, when the data stored in the storage unit 44 becomes as shown in FIG. 6B due to the new storage of the record R14 in the storage unit 44, the serial number “... 1” of the record R14. R11, R12, R1 having the same serial number as "... 1"
Regarding R3 and R14, records R11, R13, and R14
Since there is a possibility that the additional number data of 3 will be the same and there may be three or more records of the same vehicle, the record of which the additional number data is "!" Among the records R11, R13, R14. The image data of R14 is selected by the selection unit 45. However, the selection unit 4
For example, the selection unit 5 may perform the selection with respect to all the partial number data stored in the storage unit 44 every predetermined time.

The display unit 46 displays the image indicated by the image data selected by the selection unit 45, and if necessary, the partial number data and the violation data. In this case, each image may be displayed on the same screen at the same time, or may be sequentially displayed on the screen.

When the selecting unit 45 selects image data, the alarm unit 46a issues an alarm indicating that the image data has been selected.
This alarm may be any alarm such as sounding an alarm sound or displaying an alarm on the screen of the display unit 46.

The operation unit 47 operates, by an operator's operation, additional number data indicating the additional number written on the registration number mark of the infringing vehicle read from the image displayed on the display unit 46. input.

The additional writing section 50 stores the additional number data input by the operating section 47 in the storage section 44 in association with the corresponding image data.

The determining unit 51 determines whether or not the number of pieces of image data associated with the same partial number data and additional number data among the image data stored in the storage unit 44 is equal to or larger than a predetermined number. To do. In other words, the determination unit 51
Determines whether or not the number of records having the same partial number data and additional number data is a predetermined number or more. That is, it is determined whether or not there is a violating vehicle that violates a predetermined number of times or more.

In the present embodiment, the determining unit 51 causes the additional writing unit 50 to store the image stored in the storage unit 44 with respect to the partial number data associated with the additional number data newly stored in the storage unit 44. The determination is performed by determining whether or not the number of pieces of image data associated with the partial number data and the same additional number data out of the data is a predetermined number or more. In other words, when the additional writing unit 50 newly stores the additional number data in the storage unit 44, the determination unit 51 stores the partial number data associated with the additional number data in the storage unit 44. It is determined whether or not the number of pieces of image data associated with the partial number data and the same additional number data out of the existing image data is a predetermined number or more. However, the determination unit 51
For example, the determination may be performed for all the partial number data stored in the storage unit 44 every predetermined time.

When the determination unit 44 determines that the number is equal to or more than a predetermined number (that is, when the same vehicle violates a predetermined number of times or more), the output unit 48 outputs data regarding the violated vehicle. This output is, for example, a printout by a printer, recording to a large-capacity auxiliary storage medium such as a magneto-optical disk or a removable hard disk for direct transmission of data to a large-scale computer system for issuing a warning, direct transmission, etc. Is.

When the output unit 48 outputs the data, the deleting unit 49 deletes the record relating to the offending vehicle from the storage unit 44. In addition, the deletion unit 49 checks the date data of each record stored in the storage unit 44 periodically or in response to a command from the worker, and checks the date data for a predetermined period, for example, three years or more, from this date. , Delete the record.

The above-mentioned elements 43, 45, 49,
Reference numerals 50, 51, etc. are actually realized by the operation of the computer according to the program.

Next, an example of the operation of the violating vehicle analysis device 30 according to the present embodiment will be described with reference to the flowchart shown in FIG.

First, the detection section 12 of the detection unit 31 detects a vehicle in violation of axle load and outputs a detection signal (step S).
21), and in response to the detection signal, the image capturing unit 14 captures an image of the violating vehicle, obtains image data showing an image including the registration number mark of the violating vehicle, and the violating data output unit 13 outputs the violating data. Output (step S22). As a result, the transmission unit 15 transmits these image data and violation data to the reception unit 41 of the analysis unit 40 (step S23).

On the other hand, the receiver 41 of the analysis unit 40 receives the image data and the violation data (see FIG. 6A) from the transmitter 15 of the detection unit 31 (step S24).

The image processing unit 42 receives the image data from the receiving unit 41, and based on this image data, a partial number (a book number) which is a part of the registration number written on the registration number mark of the offending vehicle. In the embodiment, a 4-digit serial number is read by pattern recognition, and the serial number (for example, ".
.. "1") is obtained (step S2)
5).

Next, the writing section 43 stores the image data and the violation data from the receiving section 41 and the partial number data corresponding to them obtained by the image processing section 42 in the storage section 44 in association with each other. (Step S26).
In this step S26, for example, the record R14 in FIG. 6B is newly stored in the storage unit 44, and the storage unit 44
The data stored in is shown in FIG. 6 (b).

As described above, when the infringing vehicle is detected, the writing of the data regarding the infringing vehicle into the storage unit 44 is completed.

After that, the selecting unit 45, regarding the partial number data associated with the image data newly stored in the storage unit 44 in step S26, selects the partial number of the image data stored in the storage unit 44. Regarding the image data associated with the data, considering the additional number data,
It is determined whether or not the number of image data of the same vehicle may be three or more (step S27). In other words,
The selection unit 45 considers the possibility of the additional number data matching regarding the record having the same partial number data as the partial number data of the record newly stored in the storage unit 44 in step S26, and then the same vehicle It is determined whether there is a possibility that there will be three or more records. If NO,
The image data associated with the partial number data is 3
Since the image data does not correspond to the vehicle that may have violated more than once, the process returns to step S21 without selecting the image data.

On the other hand, if YES is determined in the step S27, the image data associated with the partial number data includes the image data corresponding to the vehicle that may have violated three or more times. Image data in which additional number data does not exist among the image data (that is, image data of the record in which the additional number data is "!")
Are selected by the selection unit 45 (step S28).

When each image data is selected by the selection unit 45, an alarm indicating that the alarm unit 46a is selected is issued (step S29), and the display unit 46 displays the image (indicated by the image data selected in step S28). The image including the registration number mark of the violating vehicle is displayed (step S30), and the operator waits for input of additional number data.

The operator observes the display unit 46 in response to the alarm issued by the alarm unit 46a, and visually observes each image (particularly the registration number mark) displayed on the display unit 46, whereby The additional number data indicating the additional number written on the registration number mark of the infringing vehicle read from the image is input by the operation unit 47. In response to this, the additional writing unit 50 stores the additional number data in the storage unit 44 in association with the corresponding image data (step S3).
1).

After that, the determination section 51 determines that the additional writing section 50
Thus, regarding the partial number data associated with the additional number data newly stored in the storage unit 44 in step S31, the partial number data and the same additional number data among the image data stored in the storage unit 44 It is determined whether the number of associated image data (that is, image data of the same vehicle) is three or more (step S3).
2). If NO, the image data associated with the partial number data is not the image data corresponding to the vehicle that has violated three or more times, and therefore the process directly returns to step S21.

On the other hand, if YES is determined in step S32 (that is, if the same vehicle violates a predetermined number of times or more), the output unit 48 outputs data relating to the violating vehicle (corresponding to the three or more image data). Output data), for example, three or more records relating to the infringing vehicle are output (step S33).

When the output unit 48 outputs the data regarding the violating vehicle, the deleting unit 49 receives the data and deletes the data regarding the violating vehicle, for example, the record regarding the violating vehicle from the storage unit 44 (step S34). ),
Return to step S21.

Although not shown in the flow chart shown in FIG. 5, the deleting section 49, as described above, periodically deletes the date of each record stored in the storage section 44 or in response to the operator's instruction. The data is checked, and the record is deleted when a predetermined period, for example, three years or more has passed from this date.

According to the violating vehicle analysis device of the present embodiment described above, it is not necessary to manually maintain and manage negatives and photographs, and all vehicles taken conventionally (all violating vehicles) Only the image of the vehicle that may have violated a predetermined number of times and the additional number data has not yet been input is displayed by the display unit 46 without manually inputting all data such as the registration number. If the operator visually checks this image and inputs only the additional number related to the image, the vehicle that has violated a predetermined number of times or more is automatically analyzed. The reading accuracy is significantly improved when a part of the registration number is read by the image processing unit 42 compared to when the image processing unit 42 reads the entire registration number from the image data. Therefore, a vehicle that may have violated a predetermined number of times or more. It is possible to appropriately select the image data. In particular, in the present embodiment, since the serial number represented by a large character is used as a partial number, the reading by the image processing means can be performed very accurately, which is preferable. However, the partial number is not limited to the serial number, and may be a combination of the serial number and the application number, for example.

Therefore, according to the present embodiment described above, it is not necessary to manually maintain and manage the negatives and photographs, and the number of data input operations is significantly reduced.
Instead of visually observing all the images obtained by the image capturing means, only the image of the vehicle that may have violated a predetermined number of times or more and the additional number data has not yet been input is visually inspected. The number of steps required to visually check the image is small. As a result, the number of steps for analyzing a vehicle that repeatedly violates is significantly reduced. In addition, since vehicles that have violated more than a specified number of times are automatically analyzed based on some numbers with extremely high reading accuracy and the additional numbers confirmed by the operator visually observing the image of the vehicle, the number of vehicles that repeatedly violate the vehicle is analyzed. It is possible to secure sufficient reliability of analysis.

As described above, according to the present embodiment, it is possible to greatly reduce the number of steps for analyzing a vehicle that repeatedly violates, and it is possible to perform a quick process.
The reliability of the analysis can be sufficiently ensured.

In the first embodiment, the operator may visually check the same image many times, whereas in the present embodiment, the operator may visually check the same image once. This is more preferable because it is not necessary to visually confirm the image for which the additional number data has been input again. Further, in the present embodiment, the image data of the vehicle that has violated a predetermined number of times or more is associated not only with the partial number data but also with the additional number data. It is preferable because it can be used.

Incidentally, in the present embodiment, the alarm unit 46a,
Although the deletion unit 49 and the like are provided, these are not always necessary.

(Third Embodiment) Next, the third embodiment of the present invention will be described.
The violating vehicle analysis device according to the embodiment will be described with reference to FIGS. 7 to 9.

FIG. 7 is a functional block diagram showing a violating vehicle analysis device according to this embodiment. FIG. 8 is a schematic flowchart showing the operation of the violating vehicle analysis device according to the present embodiment. FIG. 9 is a diagram showing an example of the structure of data used in the violating vehicle analysis device according to the present embodiment, and FIG. 9A is a diagram showing an example of the structure of data received by the receiving unit 71, FIG. b) is a diagram showing an example of a structure of data stored in the storage unit 74.

Violated vehicle analysis device 60 according to the present embodiment
Is also configured to detect and analyze an axle load violation vehicle as a violation vehicle. As shown in FIG. 7, a plurality of detection units 61 and a single analysis unit 70 respectively provided at a plurality of locations are provided. It is configured. However, in the present invention, the number of the detection units 61 may be only one depending on the application.

Each of the detection units 61 has the same structure as the detection unit 11 in the violating vehicle analysis device 10 shown in FIG. 1, and the description thereof will be omitted.

The analysis unit 70, as shown in FIG.
The receiving unit 71, the image processing unit 72, the writing unit 73, the storage unit 74, the selecting unit 75, the display unit 76, and the alarm unit 76.
a, an operation unit 77, an output unit 78, a deletion unit 79, an addition / correction writing unit 80, a determination unit 81, and a confirmation information setting unit 82.

The reception unit 71 receives the violation data and the image data transmitted from the transmission unit 15 of each detection unit 61, restores them to the original format by decoding, and sends them to the image processing unit 72 and the writing unit 73. . In this embodiment,
The structure of the data received by the reception unit 71 is, for example, as shown in FIG. 9A for one violation of one violating vehicle (that is, for one imaging). Although not shown in FIG. 9A, data such as axle load value is added as necessary as a part of the violating vehicle data.

Based on the image data from the receiving unit 71, the image processing unit 72 is a partial number which is a part of the registration number written on the registration number mark of the offending vehicle and the other part of the registration number. Is read by pattern recognition to obtain partial number data indicating the partial number and additional number data indicating the additional number. That is, in the present embodiment, unlike the above-described first and second embodiments, the image processing unit 72 recognizes all characters of the registration number. In the present embodiment, the partial number is 4
Digit serial number (reference numeral 9d is attached in FIG. 14)
Is used. Therefore, in the present embodiment, the additional number data consists of usage number data, hiragana character data, and Land Transport Office name data.

The writing unit 73 associates the image data and the violation data from the receiving unit 71 with the partial number data and the additional number data corresponding to them obtained by the image processing unit 42 with each other, and stores them in the storage unit 74. To memorize.

The storage section 74 stores the image data written by the writing section 73, the partial number data associated with the image data, the additional number data and the violation data, and a confirmation flag as confirmation information. The confirmation flag is
A state where "1" is set and a state where "0" is not set are shown. In the present embodiment, the structure of the data stored in the storage unit 74 is as shown in FIG. 9 (b).
For convenience of explanation, each data of one line in FIG. 9B (partial number data, date data, time data, place data,
The image data, the usage number data, the hiragana character data, the Land Transport Office name data, and the confirmation flag) are associated with each other, and are referred to as a record for convenience of description. Therefore, the data of one record includes partial number data, date data, time data, location data, image data, application number data, hiragana character data, and land transportation bureau that are associated with each other for one violation of one violating vehicle. It consists of name data and confirmation flag. In FIG. 9 (b),
The mark “!” Indicates that it cannot be recognized by the image processing unit 72, that data has not been input and that it has not been stored in the storage unit 74. Although not shown in FIG. 9B, data such as axle load value is added to the data of one record as a part of the violating vehicle data, if necessary.
Further, in the present embodiment, each record is sorted by partial number data (serial number in the present embodiment) in order to facilitate various processes described later.

The selecting unit 75 adds the additional number data having the associated confirmation flag of "1" (that is, the image data associated with the same partial number data among the image data stored in the storage unit 74). In consideration of the additional number data for which the confirmation flag is set), if there is a possibility that the image data of the same vehicle will exceed the predetermined number, the image data for which the related confirmation flag is “0” among the image data (That is, image data for which the confirmation flag is not set) is selected. That is, the confirmation flag is still "0".
(I.e., for the record for which addition, correction or confirmation of additional number data has not been completed yet), the additional number data can be any number even if it is not "!", And the confirmation flag is already " For records of 1 ”(that is, addition, correction, or confirmation of additional number data has already been completed), it is assumed that the additional number data is confirmed, and the same number is considered after considering the possibility of matching of the additional number data. Regarding the records having partial number data, when there is a possibility that the number of records of the same vehicle is equal to or more than a predetermined number, the image data of the record whose confirmation flag is “0” among the records is the selection unit 75.
It is selected by. In other words, in consideration of the additional number data that has been added, corrected or confirmed, of the image data corresponding to the vehicle that may have violated a predetermined number of times or more, the addition, correction or confirmation of the additional number data is still completed. The image data that has not been selected is selected by the selection unit 75.
The predetermined number is appropriately determined depending on how many times or more the vehicle that has violated is repeatedly analyzed. In the following description, it is assumed that the violated vehicle is analyzed three times or more. Therefore, in the following description, the predetermined number is "3".
For example, when the data as shown in FIG. 9B is stored in the storage unit 74, the records R21, R22, R23, and R24 having the serial number “... 1” are recorded in the records R21, R22, and R24. Since the additional number data may match, there may be three or more records for the same vehicle. Therefore, the records R21, R
The image data of the record R24 of which the confirmation flag is “0” out of 22 and R24 is selected by the selection unit 75.

In the present embodiment, the selecting section 75 stores the partial number data associated with the image data newly stored in the storing section 74 by the writing section 73 with respect to the storing section 74.
Regarding the image data associated with the partial number data among the image data stored in, the number of image data of the same vehicle may exceed a predetermined number, considering the additional number data with the confirmation flag of “1”. If there is, the selection is performed by selecting the image data with the related confirmation flag of “0” from the image data. In other words, when the writing unit 73 newly stores a record in the storage unit 74, the selecting unit 75 sets the confirmation flag to “1” for the record having the same partial number data as the partial number data of the record. If there is a possibility that the number of records for the same vehicle will exceed the specified number, considering the possibility of matching additional number data of, the image data of the record for which the confirmation flag is "0" Is selected. For example, when the record R24 is newly stored in the storage unit 74 and the data stored in the storage unit 74 becomes as shown in FIG.
Sequence number "... 1" same as sequence number "... 1" of 4
With respect to the records R21, R22, R23, and R24 that have the record, the additional number data of the records R21, R22, and R24 may match, so that the record of the same vehicle is
Since there may be more than one record, the record R2
The image data of the record R24 of which the confirmation flag is “0” among 1, R22, and R24 is selected by the selection unit 75. However, the selection unit 75 may perform the selection for all the partial number data stored in the storage unit 74, for example, every predetermined time.

The display unit 76 displays each image indicated by each image data selected by the selection unit 75, additional number data, and if necessary, partial number data and violation data. In this case, each image may be displayed on the same screen at the same time, or may be sequentially displayed on the screen.

When the selecting unit 75 selects image data, the alarm unit 76a issues an alarm indicating that the image data has been selected.
This alarm may be any alarm such as sounding an alarm sound or displaying an alarm on the screen of the display unit 76.

The operating unit 77, for each image displayed on the display unit 76, adds the image stored in the storage unit 74 to the additional number written on the registration number mark of the infringing vehicle read from the image. If the additional number data corresponding to No. does not match, an addition / correction command for adding and correcting the additional number data is output by the operator's operation, and if both match, A match confirmation command is output by the operator's operation.

The addition / correction writing unit 80 is the operation unit 7
In response to the addition / correction command from 7, the addition and correction of the additional data is performed on the data stored in the storage unit 74.

The confirmation information setting unit 82 responds to the addition or correction by the addition / correction writing unit 80 or in response to the match confirmation command from the operation unit 77, with respect to the corresponding additional number data, The confirmation flag is set (that is, the confirmation flag is set to "1").

The determination unit 81 determines a predetermined number of image data associated with the same partial number data and the same additional number data having the confirmation flag of "1" among the image data stored in the storage unit 74. It is determined whether or not the number is greater than or equal to the number. In other words, the determination unit 81 determines whether or not the number of records having the same partial number data and the same additional number data with the confirmation flag being “1” is equal to or more than a predetermined number.
That is, it is determined whether or not there is a violating vehicle that violates a predetermined number of times or more.

In the present embodiment, the determination unit 81 stores in the storage unit 74 the partial number data associated with the additional number data whose confirmation flag is newly set to “1” by the confirmation information setting unit 82. The determination is performed by determining whether or not the number of pieces of image data associated with the partial number data and the same additional number data among the stored image data is a predetermined number or more. In other words, when the confirmation information setting unit 82 stores the additional number data whose confirmation flag is newly set to “1” in the storage unit 74,
The determination unit 81 determines the number of pieces of image data associated with the partial number data and the same additional number data among the image data stored in the storage unit 74 with respect to the partial number data associated with the additional number data. Is greater than or equal to a predetermined number. However, the determination unit 81 may perform the determination for all the partial number data stored in the storage unit 84, for example, every predetermined time.

When the determination unit 74 determines that the number is equal to or more than a predetermined number (that is, when the same vehicle violates a predetermined number of times or more), the output unit 78 outputs data regarding the violated vehicle. This output is, for example, a printout by a printer, recording to a large-capacity auxiliary storage medium such as a magneto-optical disk or a removable hard disk for direct transmission of data to a large-scale computer system for issuing a warning, direct transmission, etc. Is.

When the output unit 78 outputs the data, the deleting unit 79 deletes the record relating to the offending vehicle from the storage unit 74. In addition, the deletion unit 79 checks the date data of each record stored in the storage unit 74 periodically or in response to a command from the worker, and checks the date data for a predetermined period, for example, three years or more, from this date. , Delete the record.

The above-mentioned elements 73, 75, 79,
80, 81, etc. are actually realized by the operation of the computer according to the program.

Next, an example of the operation of the violating vehicle analysis device 60 according to the present embodiment will be described with reference to the flowchart shown in FIG.

First, the detection unit 12 of the detection unit 61 detects a vehicle in violation of axle load and outputs a detection signal (step S).
41), and in response to the detection signal, the image capturing unit 14 captures an image of the infringing vehicle to obtain image data showing an image including the registration number mark of the infringing vehicle, and the infringing data output unit 13 outputs the infringing data. Output (step S42). As a result, the transmission unit 15 transmits these image data and violation data to the reception unit 71 of the analysis unit 70 (step S43).

On the other hand, the receiver 71 of the analysis unit 70 receives the image data and the violation data (see FIG. 9A) from the transmitter 15 of the detection unit 61 (step S44).

The image processing unit 72 receives the image data from the receiving unit 71, and based on this image data, a partial number (a book number) which is a part of the registration number written on the registration number mark of the offending vehicle. In the embodiment, a four-digit serial number) and an additional number that is another part of the registration number are read by pattern recognition, and the serial number (for example, "... 1") is read.
The partial number data indicating the number and the additional number data indicating the additional number are obtained (step S45). That is, the image processing unit 72 recognizes all characters of the registration number.

Next, the writing unit 73 stores the image data and the violation data from the receiving unit 71 and the partial number data and the additional number data corresponding to them obtained by the image processing unit 72 in association with each other. The data is stored in the unit 74 (step S46). In this step S46, for example,
The record R24 in FIG. 9B is newly stored in the storage unit 74, and the data stored in the storage unit 74 is shown in FIG.
As shown in (b).

With the above, when a violating vehicle is detected, the writing of the data relating to the violating vehicle into the storage unit 74 is completed.

After that, the selecting unit 75, regarding the partial number data associated with the image data newly stored in the storage unit 74 in step S46, selects the partial number from the image data stored in the storage unit 74. Regarding the image data associated with the data, it is determined whether or not there is a possibility that the number of image data of the same vehicle will be three or more in consideration of the additional number data having the confirmation flag of "1" (step S).
47). In other words, the selecting unit 75 matches the additional number data with the confirmation flag “1” for the record having the same partial number data as the partial number data of the record newly stored in the storage unit 74 in step S46. In consideration of the possibility of the above, it is determined whether or not there is a possibility that there are three or more records of the same vehicle. If NO, the image data associated with the partial number data is not the image data corresponding to the vehicle that may have violated three or more times, so that the image data is not selected and step S41 is performed.
Return to.

On the other hand, if YES in step S47, the image data associated with the partial number data includes image data corresponding to the vehicle that may have violated three or more times. Among the image data, the image data for which the confirmation flag is not set (that is, the image data of the record for which the confirmation flag is “0”) is
It is selected by the selection unit 75 (step S48).

When each image data is selected by the selection unit 75, an alarm indicating that the alarm unit 76a has been selected is generated (step S49), and the display unit 76 displays the image (indicated by the image data selected in step S48). The image including the registration number mark of the infringing vehicle) and the additional number data associated therewith are displayed (step S50), and the operator waits for the addition / correction / confirmation of the additional number data.

The operator observes the display unit 76 in response to the alarm generated by the alarm unit 76a and visually observes each image displayed on the display unit 76, whereby the registration number of the violating vehicle read from each image is read. Of the registration numbers written on the mark, the additional number is read from the storage unit 74 and compared with the additional number displayed on the display unit 66 to check whether or not there is an error. If there is an error, the operator operates the operation unit 7
Correctly input the additional number data by 7. Also,
If there is no error, the operator performs a matching confirmation operation using the operation unit 77. Further, when the additional number displayed on the display unit 26 is displayed as “!” Because the additional number cannot be recognized by the image processing unit 71, the operator uses the operation unit 77 to obtain the correct additional number data. Enter additionally.
The additional number data corrected or additionally input by the operation unit 77 is output to the addition / correction writing unit 80 as an addition / correction command, and the addition / correction writing unit 80 receives the addition / correction command, Addition / correction is performed by overwriting the data already stored in the storage unit 74 with the additional number data corrected or additionally input and rewritten. The above is the process of step S51.

Next, the confirmation information setting unit 82 responds to the addition / correction by the addition / correction writing unit 80 or in response to the match confirmation command from the operation unit 77, with respect to the corresponding additional number data. The confirmation flag is set (that is, the confirmation flag is set to "1") (step S5).
2).

[0209] After that, the determination unit 81 determines that the confirmation information setting unit 8
Regarding the partial number data associated with the additional number data whose confirmation flag is newly set to “1” by 2, the partial number data and the same additional number data of the image data stored in the storage unit 74 The number of image data (that is, image data of the same vehicle) associated with is 3
It is determined whether or not the number is equal to or more (step S53). N
If it is O, the image data associated with the partial number data is not the image data corresponding to the vehicle that has violated three or more times, and therefore the process directly returns to step S41.

On the other hand, if it is determined to be YES in step S53 (that is, if the same vehicle violates a predetermined number of times or more), the output unit 78 outputs data relating to the violating vehicle (corresponding to the three or more image data). Output data), for example, three or more records relating to the offending vehicle are output (step S54).

When the output unit 78 outputs the data regarding the violating vehicle, the deleting unit 79 receives the data and deletes the data regarding the violating vehicle, for example, the record regarding the violating vehicle from the storage unit 74 (step S55). ),
Return to step S41.

Although not shown in the flow chart shown in FIG. 8, the deleting unit 79, as described above, periodically records the date of each record stored in the storage unit 74 or in response to the operator's instruction. The data is checked, and the record is deleted when a predetermined period, for example, three years or more has passed from this date.

According to the violating vehicle analysis device of the present embodiment described above, it is not necessary to manually maintain and manage negatives and photographs, and all vehicles photographed conventionally (all violating vehicles) Only the image of the vehicle that may have violated a predetermined number of times without additional input of data such as the registration number and the additional number data that has not yet been added, corrected or confirmed is displayed. Displayed by the unit 76, the operator can visually analyze this image and only add, correct, or confirm an additional number related thereto, and the vehicle that has violated a predetermined number of times or more is automatically analyzed. The reading accuracy is significantly improved when the image processing unit 72 reads a part of the registration number from the image data as compared to when the image processing part 72 reads the entire registration number from the image data. It is possible to appropriately select the image data.

Therefore, according to the present embodiment, it is not necessary to manually maintain and manage the negatives and photographs, and the number of data input steps is greatly reduced, and the operator can obtain all the information obtained by the image pickup means. Instead of looking at the image of
Since only the image of the vehicle that may have violated a predetermined number of times and the additional number data has not yet been added, corrected or confirmed, the number of steps for visually confirming the image is small. . As a result, the number of steps for analyzing a vehicle that repeatedly violates is significantly reduced. In addition, since vehicles that have violated more than a specified number of times are automatically analyzed based on some numbers with extremely high reading accuracy and the additional numbers confirmed by the operator visually observing the image of the vehicle, the number of vehicles that repeatedly violate the vehicle is analyzed. It is possible to secure sufficient reliability of analysis.

As described above, according to the present embodiment, the number of steps for analyzing a vehicle that repeatedly violates can be significantly reduced, and quick processing can be performed.
The reliability of the analysis can be sufficiently ensured.

In the first embodiment, the operator may visually check the same image many times, whereas in the present embodiment, the operator may visually check the same image once. It is more preferable because it is not necessary to visually confirm the image to which the additional number data has been added, corrected or confirmed. Further, in the present embodiment, not only partial number data but also confirmed additional number data is associated with the image data of the vehicle that has violated a predetermined number of times or more. Number data is also available, which is preferable.

Although this embodiment is basically the same as the second embodiment, in the second embodiment,
