Description

  The present invention relates to a toll road toll collection system installed on a toll road such as an expressway.

  FIG. 10 shows a state in which a vehicle 108 enters the entrance lane 101 of a toll road toll collection system installed at the entrance of a conventional toll road in the direction of arrow A in the figure.

  The toll road toll collection system installed in the entrance lane 101 includes an approaching vehicle detector 102, an axle detector 103, a license plate detector 104, an automatic ticketing machine 105, an outgoing vehicle detector 106, a vehicle height detector 107, and A toll indicator (not shown) is installed on the roadside 110, and is a device that automatically issues a toll by detecting the type of vehicle to pass. Details will be described below.

  The approaching vehicle detector 102 includes a projector 102a and a light receiver 102b installed on both sides of the passage, and detects the approach of the vehicle 108 that passes therethrough.

  The vehicle height detector 107 includes a light projector 107a and a light receiver 107b installed in the vicinity of the projector 102a and the light receiver 102b, and detects the height (vehicle height) of the vehicle 108 that passes therethrough. Detection results by the approaching vehicle detector 102 and the vehicle height detector 107 are transmitted to the automatic ticket issuing machine 105.

  The axle detector 103 is composed of a footboard installed in a direction orthogonal to the entry direction of the entrance lane 101, and detects the number of axles (hereinafter referred to as the number of axles) of the vehicle 108 passing through. For example, the number of axes of the vehicle 108 shown in the figure is 2. The detection result by the axle detector 103 is transmitted to the automatic ticketing machine 105.

  The license plate detection device 104 includes an illumination device 104a, a camera 104b, and an image processing unit (built in). The illuminating device 104a illuminates a license plate portion (not shown) of the vehicle 8 that passes therethrough. The camera 104b reads the image of the illuminated license plate part. The image processing unit detects the position of the license plate unit from the read image, and reads and recognizes the number. The reason for recognizing the number is that the number of vehicles passed and the number given by the vehicle type are determined, and the vehicle type can be identified by recognizing this number. The recognized number is transmitted to the automatic ticketing machine 105.

  The automatic ticketing machine 105 determines the vehicle type based on the detection result of the approaching vehicle detector 102, the detection result of the vehicle height detector 107, and the recognition result of the license plate detection device 104.

  The automatic ticketing machine 105 is further provided with ticketing openings set at three levels of upper, middle, and lower, and the height of the three levels based on the vehicle type and vehicle height determined by the automatic ticketing machine 105. Is selected, and a pass ticket is issued from the selected ticket opening. In recent years, a method of automatically moving the height of the ticketing slot based on the vehicle type and the vehicle height is known (for example, see Patent Document 1).

  The transmission vehicle detector 106 detects the exit of the vehicle 108.

A toll indicator (not shown) is an indicator that displays a toll on a toll road, and is disposed in an entrance lane or an exit lane that uses a flat fee. In the conventional system described above, the position and display angle of the charge indicator are fixed.
JP-A-7-320101 (page 1-3, FIG. 4)

  However, the toll road toll collection system described in Patent Document 1 has the following problems.

  First, since the vehicle height detector 107 requires a long sensor to measure the height of the vehicle, the vehicle height detector 107 is easily affected by attachment errors, vibrations, and the like, and is likely to become unstable. Moreover, since the installation interval of the projector 107a and the light receiver 107b is large, it is difficult to adjust the optical axis. Furthermore, for the reasons described above, there is a problem that the optical axis pitch becomes rough and the vehicle height cannot be measured finely.

  Secondly, the height of the ticketing gate of the automatic ticketing machine 105 is such that the driver is not necessarily in a position corresponding to the vehicle type and height, such as a large mezzanine tour bus with a high car height but a low driver's seat. In some cases, it may not exist and it may be difficult to receive a pass. As a result, there was a risk of unsafeness such as a tollgate traffic jam or forced reception posture.

  Thirdly, since the license plate detection device 104 has a single camera and a fixed viewing angle, there is a risk that the literacy rate of the license plate information may decrease due to the vehicle approach angle, the deformation of the license plate, the adhesion of dirt, and the like. is there.

  Fourth, since the position indicator and the display angle of the toll indicator do not change even if the position of the driver changes depending on the type of vehicle passing through, the visibility of the display unit from the driver may be depending on the vehicle. There was a bad case.

  The present invention has been made to solve the above problems, and detects the height position of a driver who drives a vehicle from an image captured by a camera, and inputs a ticketing gate of an automatic ticketing machine and a charge collector. Provided is a toll road toll collection system that makes it easy to exchange a toll or a toll by changing the display angle of a mouth or a toll indicator according to the height of the driver.

  In order to achieve the above object, a toll road toll collection system according to claim 1 of the present invention is installed at a toll gate of a toll road and detects an approaching vehicle and an approaching vehicle detection means. When the vehicle is detected, a camera that images the front of the vehicle, and image processing means that detects height position information of a driver driving the vehicle from the front image of the vehicle captured by the camera And a height for changing the height of the ticket entrance of the automatic ticketing machine that issues the pass ticket or the medium entrance of the toll collector that collects the fee based on the height position information of the driver detected by the image processing means And adjusting means.

  The toll road toll collection system according to claim 2 of the present invention is installed at a toll gate on a toll road and detects an approaching vehicle detecting means for detecting an approaching vehicle, and the approaching vehicle detecting means detects the vehicle. A camera that captures the front of the vehicle, an image processing unit that detects height position information of a driver who drives the vehicle from a front image of the vehicle captured by the camera, and the image processing unit Display angle adjusting means for changing a display angle of a toll indicator that displays a toll based on the driver's height position information detected by the above.

  Further, an approaching vehicle detection means for detecting an approaching vehicle installed at a toll gate on a toll road, and a predetermined interval for imaging the front of the vehicle when the approaching vehicle detection means detects the vehicle First recognition for recognizing character information on a license plate of the vehicle using a first camera and a second camera that are spaced apart and a front image of the vehicle imaged by the first camera And the first information for recognizing the character information on the license plate of the vehicle using the front image of the vehicle imaged by the second camera when the first recognition means does not succeed. Two recognition means, and as a result of recognition by the first recognition means and the second recognition means, the one with more recognition information is used as license plate information.

  According to the present invention, the height position of the driver who drives the vehicle is detected from the image captured by the camera, and the display angle of the ticket issuing port of the automatic ticketing machine, the charge input port of the toll collector, or the charge indicator is set. By changing according to the height of the driver, it is possible to provide a toll road toll collection system that facilitates the exchange of tolls or tolls.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an example of an installation diagram in which the toll road toll collection system of the present invention is installed in a toll gate entrance lane. This figure shows a state where a vehicle 8 has entered the entrance lane 1a of the toll road toll collection system installed at the entrance of the toll road in the direction of arrow A in the figure. FIG. 2 is a device configuration diagram when the system is applied to an entrance lane. The configuration will be described below with reference to FIGS.

  In the toll road toll collection system installed in the entrance lane 1a, an approaching vehicle detector 2, an axle detector 3, an image processing device 4, an automatic ticketing machine 5, and an outgoing vehicle detector 6 are installed on the roadside 10 and pass through. This is a device that automatically detects the type of the vehicle 8 to be issued and issues a pass ticket. Details will be described below.

  The approaching vehicle detector (approaching vehicle detection means) 2 is composed of a projector 2a and a light receiver 2b arranged on both sides of the lane, and the light emitted from the projector 2a is detected by the light receiver 2b. When the vehicle 8 enters between the light projector 2a and the light receiver 2b, the light is blocked. A unit in which this light is continuously blocked is detected as one vehicle.

  The axle detector 3 is composed of a footboard arranged in a direction orthogonal to the approach direction of the entrance lane 1a, and counts the number of times the footboard is stepped while the approaching vehicle detector 2 is detecting the vehicle 8. To count the number of axles below the number of axles. The number of axes is detected for each approaching vehicle. For example, the number of axes of the vehicle 8 shown in the figure is 2. The detection result by the axle detector 3 is transmitted to the automatic ticketing machine 5.

  The image processing device 4 includes a lighting device 40, a camera 41, a camera 42, and an image processing unit 43.

The lighting device 40 illuminates the front surface of the vehicle 8 that passes therethrough.
The camera 41 (first camera) and the camera 42 (second camera) are arranged with a predetermined distance in the horizontal direction with respect to the lane 1a, and constitute a so-called binocular camera or stereo camera. When the approaching vehicle detector 2 detects the front end of the vehicle 8, the front part of the vehicle 8 is individually imaged in synchronization with the front end detection of the vehicle 8, and the captured image data is captured by the image processing unit 43. Send to.

  The image processing unit (image processing means) 43 stores the received image data in the image memories 43a and 43b and performs image processing. The image processing unit 43 uses a pattern recognition technique based on the image data in the image memory 43a among the two image data stored in the image memory 43a (image memory 1) and the image memory 43b (image memory 2). It has the 1st recognition means which recognizes the external dimension of a license plate, and the character information on a license plate. If recognition of part or all of the license plate information is not successful, a second recognition unit for recognizing the license plate character information based on the image data in the image memory 43b is provided. As a result of recognition by the first recognition means and the second recognition means, the one with more recognition information is transmitted to the automatic ticket issuing machine 5 as license plate information.

  The image processing unit 43 further identifies the driver in the vehicle based on the one image data, and detects position information regarding the height. When a plurality of human image candidates are detected in the vehicle, the driver who has the position of the plurality of persons closest to the camera 41 or the camera 42 based on the two separately captured image data is a driver. And detect information about its height. This detection result is transmitted to the automatic ticketing machine 5.

  FIG. 3 is a schematic configuration diagram of the automatic ticketing machine 5. The automatic ticketing machine 5 includes a ticketing slot 51, a ticketing slot driving unit 52, a ticketing unit 53, a waste ticket stocker 54, and a control unit 55.

The ticket issuing port 51 is a port that passes the pass ticket P to the user (driver).
The ticket issuing slot drive unit (moving means) 52 connects a gear 52b incorporated in the rotating shaft of the drive motor 52a and a gear 52d arranged in the vertical direction of the gear 52b by a timing belt 52c, and the ticket issuing slot is connected to the timing belt 52c. 51 is connected. With such a configuration, it is possible to move the ticket issuing port 51 to an arbitrary position in the vertical direction within a predetermined range indicated by an arrow C in the drawing.

  The ticket issuing unit 53 creates a toll ticket in which entrance information such as vehicle type information, installation toll gate number, and ticket issuing time information determined by the control unit 55 is recorded.

  The waste ticket stocker 54 is a part that is taken in and accommodated when the user (driver) forgets to take the pass ticket P.

  The control unit 55 is configured to calculate the toll based on the detection result of the approaching vehicle detector 2, the detection result of the axle detector 3, and the license plate information of the image processing device 4. Car type classification (vehicle type information) is performed on any of the above.

  FIG. 4 is a detailed view of the ticket issuing opening 51. The ticket issuing port 51 includes a means for holding the pass ticket P and a drive means for transporting the pass ticket P. A drive roller 51a and a pickup roller 51b are provided at the exit of the pass ticket P as means for holding the pass ticket P. The driving means for transporting the pass ticket P includes a driving motor 51d, a gear 51e for transmitting the driving force of the driving motor 51d, and a timing belt 51c. The passing ticket P is transported from the ticket issuing unit 53 by transporting means such as the transporting rollers 53a and 53b or the transporting belt 54, and any of them can be transported by existing technology and will not be described in detail.

  The passing ticket P is transported in the direction indicated by the arrow B, and when the leading edge is detected by the timing sensor 51f, the passing ticket P projects a predetermined length downstream from the holding position of the drive roller 51a and the pickup roller 51b and stops. Let In this state, the vehicle user (driver) waits for the passing ticket P to be extracted.

  On the other hand, when the pass ticket P is not extracted (details will be described later), the drive motor 51d is reversely rotated to take the pass ticket P into the pass ticket holder 51g in the apparatus.

The operation of the automatic ticketing machine 5 configured as described above will be described.
First, the pass ticket P created by the ticket issuing unit 53 is transported in the direction of the arrow B shown in the figure, and sent to the pass ticket holder unit 51 g in the ticket issuing port 51.

  Next, based on the driver height position information detected by the image processing device 4, the ticket outlet driving unit 52 moves the ticket outlet 51 to a height most suitable for the driver height position and stops it. Then, a part of the pass ticket P is protruded from the ticket issue port 51 from the pass ticket holder part 51g in the ticket issue port 51 and waits until the pass ticket P is extracted. When the pass ticket P is extracted, the process proceeds to the ticket issuing process for the next vehicle. If the departure vehicle detector 6 detects that the vehicle has exited without the passing ticket P being extracted, the passing ticket P is taken into the passing ticket holder 51g and the ticket opening 51 is introduced into the waste ticket stocker 54. Moving to the mouth, the pass ticket P is accommodated in the waste ticket stocker 54, and the process proceeds to the ticket issuing process for the next vehicle.

  FIG. 5 is an image diagram of the vehicle and the occupant in the image memory. In this figure, the leading end in the traveling direction of the large mezzanine sightseeing bus 8a where the vehicle height is high but the driver's seat is low is detected by the approaching vehicle detector 2, and image data captured in synchronization with this detection is stored in the image memory. It is the image figure memorize | stored in. Horizontal coordinates X000 to X800 represent the imaging range in the width direction of the lane, and vertical coordinates Y000 to Y500 represent the imaging range in the height direction from the road surface. A portion surrounded by the maximum values of the horizontal coordinate X and the vertical coordinate Y is an imaging range, and arbitrary image data in the imaging range can be read by the horizontal coordinate X and the vertical coordinate Y.

Further, the resolution of the image is determined by the optical magnification of the optical system to be imaged. For example, if the maximum value Y500 of the vertical coordinate Y is set so as to correspond to a height of 4 m (= H2) from the road surface, the vertical coordinate resolution K corresponds to 80 mm according to the following equation (1). If the horizontal pixels and vertical pixels of the camera that captures an image are configured to have the same size, the values of the horizontal resolution and the vertical resolution are equal, and in this case, both are 8 mm. Further, the height H1 to the driver when the driver 8b in the image data captured by the camera configured as described above is detected by image processing described later is calculated by the following equation (2).
Vertical coordinate resolution: K = 4 m (= 4000 mm) / 500 = 8 mm (1)
Driver height: H1 = KYn (2)
Yn: Indicates that the value of the vertical coordinate is n.

  FIG. 6 is a flowchart for explaining the operation of the equipment installed in the entrance lane 1a. Hereinafter, description will be made with reference to FIGS.

  First, the vehicle 8 is monitored by the approaching vehicle detector 2. If the vehicle 8 is not detected as a result of monitoring by the vehicle detector 2 (No in S1), the vehicle detector 2 continues monitoring until the vehicle 8 is detected.

  On the other hand, when the vehicle 8 is detected by the vehicle detector 2, the shaft number counting process by the axle detector 3, the vehicle number recognition process by the camera 41 and the camera 42, and the driver height position detection process are performed simultaneously. Is called.

First, the axis number counting process will be described.
The axis number counter counted by the axle detector 3 is cleared (initialized) to “0” (S2).

  Next, if the number of axes is detected by the axle detector 3 (Yes in S4), the number of axes counter is set to +1 (S5), and if the number of axes is not detected, vehicle detection by the approaching vehicle detector 2 is performed (S6). ).

  As a result of the vehicle detection by the vehicle detector 2, if the vehicle is being detected (No in S6), the detection of the number of axes by the axle detector 3 is repeated until the vehicle passing by the approaching vehicle detector 2 is completed (S4 to S6). ).

  Next, when the approaching vehicle detector 2 detects that the vehicle has passed in step S6 (Yes in S6), the number-of-axis counter value is transmitted to the automatic ticketing machine 5 (S7). With the above processing, the axis number counting processing is completed.

Next, vehicle number recognition processing will be described.
When the vehicle detector 2 detects the vehicle 8 in step S1 (Yes in S1), the front surface of the vehicle 8 is synchronized with the front end detection of the vehicle 8 by the camera 41 (camera 1) and the camera 42 (camera 2). (S3).

  Next, vehicle number recognition processing is performed based on the image data in the image memory 43a (image memory 1) (S8). As a result of the vehicle number recognition process, if successful, the vehicle number data is transmitted to the automatic ticketing machine 5 (S11). On the other hand, if the vehicle number recognition process is not successful, the vehicle number recognition process is performed based on the data in the image memory 43b (image memory 2) (S10). Transmit (S11). The vehicle number recognition process is completed by the above process. In addition, although not shown in figure, you may apply the process of S8-S11 to the process of driver | operator detection mentioned later.

Next, the driver height position detection process will be described.
A person image is extracted based on the image data of the image memory 43a and the image memory 43b (S12).

  Next, the number of people images extracted is confirmed. As a result of this confirmation, if the person is alone (Yes in S13), the height position of the person image is detected from the image memory coordinate position where the person image exists (S16). The driver's height position information, which is the detection result, is transmitted to the automatic ticketing machine 5 (S17).

  On the other hand, if the extracted person image is not one in S13 (No in S13), the camera 41 (camera 1) is selected based on the image data in the image memory 43a (image memory 1) and the image memory 43b (image memory 2). ) The distance from the camera 42 (camera 2) to a plurality of person images is calculated by three-dimensional surveying (three-dimensional surveying means, S14).

  Next, a person image closest to the camera (a shadow existing in the foreground of the vehicle) is specified from the calculated distance (S15). The height position of the person image specified in this way is detected (height position information detecting means, S16), and the height position information of the driver as the detection result is transmitted to the automatic ticketing machine 5 (S17). . With the above processing, the driver height position detection processing is completed.

  When the above-described number-of-axis counting process, vehicle number recognition process, and driver height detection process are completed, an automatic ticket-issuing machine process is performed based on these processing results. In the example of FIG. 5, the height H1 of the driver is used as the head of the driver image. However, the present invention is not limited to this.

FIG. 7 is a flowchart for explaining automatic ticket-issuing machine processing. Hereinafter, description will be given with reference to FIGS.
The axis number counter value obtained as a result of the axis number counting process by the control unit 55, the vehicle number data obtained as a result of the vehicle number recognition process, and the height position of the driver obtained as a result of the driver height detection process It is confirmed whether information has been received (S20). If the reception is not completed as a result of this confirmation (No in S20), the process waits until the reception is completed.

  When the reception is completed as a result of the confirmation (Yes in S20), the ticket issuing unit 51, which is the height adjusting means, moves the ticket issuing port 51 to the ticket issuing unit 53 and holds (holds) the ticket P in the ticket holder unit 51g. (S22).

  Next, the ticketing slot driving unit 52 is driven by the drive motor 52a to move the ticketing slot 51 to the driver's height (S22).

  Next, the drive roller 51a of the ticket issuing slot holder 51g is driven to cause the passing ticket P to protrude from the ticket issuing slot (S23).

  Next, it is monitored whether the pass ticket P has been extracted (S24). As a result of this monitoring, if the passing ticket is not extracted, it is monitored whether the departure vehicle detector 6 detects the exit of the vehicle (S25). If no vehicle exit is detected as a result of this monitoring (No in S25), the removal of the pass ticket and the vehicle exit by the departure vehicle detector 6 are monitored (S24, S25).

  As a result of this monitoring, when the passing ticket is extracted (Yes in S24), the automatic ticket-issuing machine processing is terminated. On the other hand, if the departure of the vehicle is detected as a result of monitoring of the departure of the vehicle by the departure vehicle detector 6 (Yes in S25), it is assumed that the vehicle has left without being taken out and the passage ticket is discarded. To house. The automatic ticket-issuing machine process is complete | finished by the above process.

  In the above-described embodiment, belts or the like as shown in FIGS. 3 and 4 are used as means for changing the height of a ticket issuing gate or a toll collection medium entrance according to the height position of the driver. Although the means for moving the height has been described, as another embodiment, the conventional multi-ticket issuing machine shown in FIG. 10 is used to issue a ticket from the ticket issuing slot close to the height position of the driver detected by image processing. It is good.

  FIG. 8 is an example of an installation diagram in which the toll road fee collection system of the present invention is installed in the toll gate exit lane. This figure shows a state in which a vehicle 8 has entered the exit lane 1b of the toll road toll collection system installed at the exit of the toll road in the direction of the arrow A in the figure.

  The toll road toll collection system installed in the exit lane 1b includes an approaching vehicle detector 2, an image processing device 4, a toll collector 11, a toll indicator 12, and a starting vehicle detector 6, and a vehicle 8 passing therethrough. The toll is displayed on the toll indicator 12 and the toll collector 11 collects the toll. Details will be described below.

  The approaching vehicle detector 2 and the image processing device 4 are the same as those installed in the entrance lane 1a shown in FIG. The detection result and the processing result are transmitted to the charge receiver 11 and the charge indicator 12.

  The toll collector 11 is provided with three pass ticket inlets 11a for inserting a pass ticket issued from the automatic ticketing machine 5 shown in FIG. 1, and three charge input ports 11b for inputting a toll. . There is a case where a card insertion slot for inserting a card such as a prepaid card is provided in the charge insertion slot 11b. The toll collector 11 configured as described above performs toll collection processing based on the pass ticket information input from the user of the vehicle 8 that has entered the exit lane 1b. At this time, according to the height position information of the driver of the image processing device 4, a set of heights respectively selected from the three pass ticket entrances and toll entrances is set to a height suitable for the driver's height position. Adjust it. Also in this case, in addition to moving and adjusting a set of height positions, only a set of mouth heights close to the detected height position may be validated or displayed.

  The charge indicator 12 is provided with a display part 12a for displaying a charge and a display angle adjusting mechanism (display angle adjusting means) 12b for adjusting the angle of the display part 12a within a range indicated by an arrow 12c. The display angle adjustment mechanism 12b adjusts the display angle of the display unit 12a to a height suitable for the height position of the driver according to the height position information of the driver of the image processing device 4. By adopting such a configuration, it is possible to make the charge indicator 12 with good visibility from any driver who drives the vehicle 8.

  The calling vehicle detector 6 detects the exit of the vehicle 8 and shifts to a toll collection process for the next vehicle according to the detection result.

  FIG. 9 shows a modification of the charge indicator. This display device includes a display unit 13a for displaying a charge, a display unit 13b, and a display angle adjusting mechanism (display angle adjusting unit) 13c. The functions of each display unit and the display angle adjustment mechanism are the same as in the case of the single charge indicator described above. In this way, the same effect as changing the display angle by including a plurality of display units corresponding to a plurality of height positions and changing the display unit to be displayed according to the height position of the driver is obtained. Obtainable. In the illustrated example, a display angle adjustment mechanism is provided, but it is used according to the use situation.

  By adopting such a configuration, the vehicle height detector which is the first problem is not required, so that it is not necessary to adjust the optical axis between the projector and the light receiver constituting the vehicle height detector. In addition, it is difficult to receive tolls and collect tolls when there is no driver at a position corresponding to the vehicle type and height, such as the 2nd and 4th large mezzanine tour buses. The poor visibility of the display is eliminated. Furthermore, the literacy rate of the license plate information is improved by recognizing the vehicle number of the license plate using two cameras as the second problem.

  The present invention is not limited to this, and can be applied to, for example, an automatic ticketing machine disposed at the entrance of a pay parking lot or a similar system.
