Description

  The present invention relates to a package inspection system.

  In airports and the like, a baggage inspection system is used in which an inspector performs a security check based on an image (for example, an X-ray image) obtained by capturing baggage or the like with a baggage imaging device such as an X-ray imaging device. In recent years, a baggage inspection system has been proposed in which images captured by a plurality of baggage imaging devices are transmitted to a remote interpretation terminal, and an inspector skilled at the interpretation terminal collectively inspects the image (Patent Literature). 1).

Special table 2009-510394 gazette

  By the way, in the conventional luggage inspection system, the length of the queue of the owner of the luggage to be inspected (hereinafter referred to as the person to be inspected) is not considered. For this reason, when there are multiple inspection lanes where the baggage imaging devices are installed, the deviation cannot be quickly resolved when deviations occur in the queue lengths of the inspectees lined up in each inspection lane. There has been a problem that the inspection time, which is a combination of the waiting time in the inspector's queue and the interpretation time, is biased among the examinees. In other words, even if the test subject has begun to line up at the same time, the test time of the test subject in the test lane with the long queue is longer than the test time of the test subject in the test lane with the short queue As a result, the feeling of unfairness was given to the examinees.

  Therefore, the present invention preferentially inspects inspection lanes that have a long queue, that is, a large number of subjects to be inspected, and thereby level out the inspection times of a plurality of inspection lanes, thereby suppressing uneven inspection times. The purpose is to do.

  One aspect of the present invention includes an imaging unit that captures an inspected person's luggage, a plurality of luggage imaging apparatuses that transmit the captured image, and displays the image, and accepts an input of an inspection result by an inspector. A package inspection system comprising: an interpretation terminal; and a server that distributes the images transmitted from the plurality of package imaging devices to the interpretation terminal, wherein each package imaging device is waiting for an inspection of the package. Number counting means for acquiring the waiting number of persons to be inspected, and inspection information storage means for storing inspection information in which the image captured by the luggage imaging device is associated with an identifier of the luggage imaging device. , A number information storage means for storing the number of persons information in which the waiting number of persons is associated with the identifier of the luggage imaging device for each of the luggage imaging devices, and the waiting person with reference to the inspection information and the number of people information There, characterized in that it and a delivery sequence determination means for delivering to the interpretation terminal from the server the images captured more preferentially at higher said package imaging device.

  Here, it further includes an elapsed time measuring means for measuring an elapsed time from the time taken by the baggage imaging device for each image, and the delivery order determining means is configured such that the elapsed time is equal to or greater than a predetermined threshold time. It is preferable to distribute the image from the server to the image interpretation terminal with higher priority regardless of the number of waiting persons.

  Further, the waiting number is the sum of the number of the inspected persons waiting for imaging by the luggage imaging apparatus and the number of the inspecting persons waiting for the inspection result after imaging by the luggage imaging apparatus. The delivery order determining means refers to the number of persons information, and when the difference between the maximum value and the minimum value of the number of waiting persons for each of the luggage imaging devices is equal to or less than a predetermined threshold number of persons, Regardless of this, it is preferable that the image captured by the baggage imaging apparatus having a larger number of waiting for inspection results is more preferentially distributed from the server to the image interpretation terminal.

  In addition, the luggage imaging device includes a conveyance unit that automatically conveys the luggage to the imaging unit, and a conveyance speed adjustment that increases a conveyance speed of the conveyance unit as the inspection processing speed of the image increases for each of the luggage imaging devices. It is preferable to provide means.

  According to the present invention, it is possible to provide a baggage inspection system that equalizes inspection times of a plurality of inspection lanes and suppresses uneven inspection time.

Make it. Further, when receiving an image from the luggage imaging apparatus 102, the control unit 30 assigns an image ID that is a unique identifier to the image and stores it as image information 32c. In addition, the control unit 30 receives the inspection result of the image from each interpretation terminal 106 and transmits the inspection result to the luggage imaging apparatus 102 that is the transmission source of the image. Further, the control unit 30 functions as a delivery order determining unit 30a and an elapsed time measuring unit 30b. Here, the delivery order determination unit 30a refers to the examination information 32a and the number information 32b, and gives priority to the image of the baggage captured by the baggage imaging device 102 having a larger waiting number from the server 104 to the image interpretation terminal 106. A distribution order determination process for distribution is executed. Details of the delivery order determination process will be described later. Further, the elapsed time measuring unit 30b performs a process of measuring an elapsed time from the time when the baggage imaging apparatus 102 images each baggage image.

  The storage unit 32 stores information processed by the control unit 30 such as examination information 32a, number of people information 32b, and image information 32c.

  As shown in FIG. 4, the inspection information 32 a includes an image ID that is an identifier of a package image transmitted from the package imaging device 102, a package imaging device ID that is an identifier of the package imaging device 102 that captured the package image, It is a database associating inspection states and waiting times. Here, the inspection state is an uninspected state indicating that the image of the parcel has not been inspected, an inspecting state indicating that the parcel is being inspected by the image interpretation terminal 106, and the inspection indicates that there is no problem with the parcel. It is information indicating one of the NG states in which there is a problem with the package by the state and inspection. The waiting time is information indicating an elapsed time from when a package image is captured by the package imaging apparatus 102 until the image is distributed. In this embodiment, processing is performed so that the package image captured by the package imaging device 102 is instantaneously transmitted to the server 104, so that the elapsed time from the time at which each package image is received by the server 104 is calculated. Wait time. After the package image is distributed from the server 104 to one of the image interpretation terminals 106, the waiting time for the image of the package is cleared.

  For example, in the example of the inspection information 32a in FIG. 4, the image of the package specified by the image ID “000001” is captured by the package imaging device 102c, the inspection state is “NG state”, and has already been inspected. Is finished and the waiting time is cleared. The package image specified by the image ID “000002” is captured by the package imaging apparatus 102a, the inspection state is “OK state”, and the inspection has already been completed and the waiting time has been cleared. The package image specified by the image ID “000003” is captured by the package imaging apparatus 102b, the inspection state is “uninspected”, and the waiting time from the imaging is 13 (the unit is arbitrary). . The package image identified by the image ID “000005” is captured by the package imaging apparatus 102a, the inspection state is “under inspection”, and the waiting time is cleared.

  As shown in FIG. 5, the number-of-persons information 32b is a database in which the number of waiting for imaging, the number of waiting for inspection results, and the number of waiting are associated with the baggage imaging device ID of each baggage imaging device 102. When the server 104 receives the number of people waiting for imaging, the number of people waiting for the inspection results, and the number of people waiting for the images counted by the number counting unit 16 of the baggage imaging apparatus 102, the control unit 30 of the server 104 And the waiting number as the total number thereof is stored as the number information 32b in association with the baggage image pickup device ID of each baggage image pickup device 102.

  For example, in the example of the number information 32b in FIG. 5, the luggage imaging apparatus ID “A” indicating the luggage imaging apparatus 102a includes 6 persons waiting for imaging, 2 persons waiting for the inspection result, and the waiting number that is the sum of them. 8 people are registered. Also, in the baggage imaging apparatus ID “B” indicating the baggage imaging apparatus 102b, two people are registered as the number of people waiting for imaging, one is the number of people waiting for the inspection result, and three people are waiting as the total number of them. Also, in the baggage image pickup apparatus ID “C” indicating the baggage image pickup apparatus 102c, three people are registered as the number of people waiting for imaging, one person is waiting as the inspection result, and four people are waiting as the total number of them.

  Note that the number of test result waiters can also be obtained from the test state of the test information 32a. That is, the number of images waiting for the inspection result can be obtained by counting the number of images in which the inspection state is not inspected or being inspected for each baggage imaging apparatus 102. In this case, the waiting number of people can be received from the number counting unit 16 of the baggage imaging apparatus 102, and the waiting number can be obtained by using the number of people waiting for the inspection result obtained by the above method.

  The image information 32c is a database in which the image data of each package received from each package imaging device 102 is associated with the image ID assigned thereto.

  The input unit 34 includes an information input device such as a keyboard and a mouse, and is used to input instructions and information to the server 104. The output unit 36 includes an information output device such as a display or a printer, and is used to output information processing information in the server 104. The communication unit 38 includes a network interface and the like, and communicates with the baggage imaging apparatus 102 and the image interpretation terminal 106 via the information communication network 108.

  Next, the interpretation terminal 106 will be described. The image interpretation terminal 106 receives distribution of the package image from the server 104 and presents the image to an inspector who operates the terminal to inspect the package. The image interpretation terminal 106 receives the input of the inspection result for the package image and transmits the inspection result to the server 104. The interpretation terminal 106 includes a control unit 40, a storage unit 42, an input unit 44, an output unit 46, and a communication unit 48, as shown in the device configuration diagram of FIG.

  The control unit 40 includes an information processing device such as a CPU or ASIC, and controls information processing in the image interpretation terminal 106. The storage unit 42 stores information used for information processing at the image interpretation terminal 106 such as a package image received from the server 104. The input unit 44 includes an information input device such as a keyboard and a mouse, and receives an instruction to the image interpretation terminal 106 and an input of an inspection result from an inspector. The output unit 46 includes an information output device such as a display or a printer, and is used to output information such as an image of a package. The communication unit 48 includes a network interface and the like, and communicates with the luggage imaging device 102 and the server 104 via the information communication network 108.

[Package inspection processing]
Hereinafter, a package inspection process using the package inspection system 100 according to the present embodiment will be described. The package inspection process is executed along the flowchart of FIG.

  In step S <b> 10, the number of inspected persons lined up in the inspection lane of the luggage imaging apparatus 102 is counted. The number of persons counting unit 16 counts the number of persons waiting to be imaged and the number of persons waiting for the inspection results, which are lined up in each inspection lane of the luggage imaging apparatus 102. The number of persons counting unit 16 calculates the number of waiting persons, which is the total number of persons waiting for imaging and waiting for examination results. The parcel imaging device 102 transmits the parcel imaging device ID of the parcel imaging device 102, the number of waiting for imaging, the number of waiting for inspection results, and the waiting number of people to the server 104 via the communication unit 18.

  In step S12, the server 104 performs update processing of the number information 32b. The server 104 receives the baggage imaging device ID, the number of people waiting for imaging, the number of people waiting for the inspection result, and the number of people waiting for the baggage imaging device 102 via the communication unit 38, and the package received from the baggage imaging device 102 as shown in FIG. The number information 32b in the storage unit 32 is updated with the imaging device ID, the number of people waiting for imaging, the number of people waiting for examination results, and the number of people waiting.

  In addition, it is suitable to repeat the process of step S10 and S12 at an appropriate timing. For example, it is preferable to update the number-of-persons information 32b by repeating the processes of steps S10 and S12 at regular intervals.

  In step S <b> 14, an image of the luggage is captured by the luggage imaging apparatus 102. The X-ray imaging unit 10 images the luggage of the first person to be inspected while waiting for imaging. The parcel imaging device 102 transmits the parcel image and its parcel imaging device ID to the server 104 via the communication unit 18.

  In step S16, the server 104 performs registration processing of the image information 32c. When the server 104 receives an image of the package from the package imaging device 102 via the communication unit 38, the server 104 assigns an image ID that is a unique identifier to the image, associates the image data with the image ID, and stores the image in the storage unit 32. Is stored as image information 32c.

  In step S18, the server 104 performs a process for updating the inspection information 32a. The server 104 associates the baggage image pickup device ID of the baggage image pickup device 102 that picked up the image of the baggage with the image ID of the baggage image received from the baggage image pickup device 102, and sets the inspection state to “uninspected”. Store as 32a. Furthermore, the waiting time is started from the initial value 0.

  In addition, it is suitable to repeat the process of step S14-S18 at an appropriate timing. For example, it is preferable to update the image information 32c and the inspection information 32a by repeating the processes of steps S14 to S18 at regular intervals.

  In step S <b> 20, an image acquisition request process is performed from the image interpretation terminal 106. An image acquisition request signal is transmitted to the server 104 via the communication unit 48 in accordance with an instruction input from an inspector who is operating the radiogram interpretation terminal 106 that is in an empty state after the previous examination is completed.

  In step S22, the server 104 that has received the image acquisition request signal performs a distribution order determination process for determining the distribution order of the package images. According to the determined distribution order, the server 104 receives the image acquisition request source. A package image is distributed to the interpretation terminal 106. The delivery order determination process will be described later. By this processing, the control unit 30 of the server 104 functions as the distribution order determining unit 30a. In addition, the server 104 updates the inspection state associated with the image ID of the package image distributed to the image interpretation terminal 106 in the inspection information 32a to “under inspection”.

  In step S24, the image of the parcel is inspected at the interpretation terminal 106. The image interpretation terminal 106 that transmitted the image acquisition request in step S20 receives the image data of the package image transmitted from the server 104 in step S22 via the communication unit 48. The image interpretation terminal 106 displays an image of the package on the output unit 46 based on the received image data, and causes the inspector to inspect the image (security check). The image interpretation terminal 106 receives the inspection result (OK state or NG state) from the inspector via the input unit 44 and transmits the inspection result together with the image ID of the package image to be inspected to the server 104 via the communication unit 48. To do.

  In step S26, the server 104 performs a process for the inspection result notification process. When the server 104 receives the image ID and the inspection result of the package image transmitted from the image interpretation terminal 106 via the communication unit 38, the server 104 updates the inspection state associated with the image ID in the inspection information 32a with the received inspection result. To do. Further, the server 104 reads the package imaging device ID associated with the image ID in the inspection information 32a, and sends the inspection result to the package imaging device 102 corresponding to the package imaging device ID via the communication unit 38. Send.

  In step S28, processing corresponding to the inspection result is performed in the luggage imaging apparatus 102. The package imaging apparatus 102 that is the transmission destination in S26 receives the inspection result transmitted from the server 104 via the communication unit 18, and executes a process according to the inspection result. The control unit 20 of the baggage imaging apparatus 102 outputs a gate control signal corresponding to the received inspection result to control the opening / closing of the gate 14. Specifically, if the inspection result is “OK state”, the gate 14 is opened. If the inspection result is “NG state”, the passage of the inspected person who holds the inspected baggage with the gate 14 closed is physically performed. To control. When the inspection result is “NG state”, the alarm means (warning light, warning buzzer) provided in the baggage imaging apparatus 102 is notified to the guards and the like, and the baggage in “NG state” is possessed. It is preferable to remove the subject from the inspection lane.

[Delivery order determination processing for package images]
Next, the package image distribution order determination process in step S22 will be described. The delivery order determination process is executed along the flowchart of FIG. The distribution order determination process is executed by the control unit 30 of the server 104 with reference to the examination information 32a stored in the storage unit 32.

  In step S30, it is determined whether or not there is an uninspected image in which the inspection state of the inspection information 32a is “uninspected”. If no uninspected image exists in the inspection information 32a, the process proceeds to step S32. If present, the process proceeds to step S34.

  In step S <b> 32, the server 104 transmits information indicating that there is no unexamined image to the image interpretation request source image interpretation terminal 106 via the communication unit 38. Thereby, the delivery order determination process ends.

  In step S34, it is determined whether or not there is an uninspected image whose “waiting time” in the inspection information 32a is equal to or longer than a predetermined threshold time. Here, the predetermined threshold time is a time that the inspected person feels unable to wait when the waiting time for the inspection becomes longer than this, and is preferably set in advance by an administrator or the like. If there is an uninspected image whose “waiting time” in the inspection information 32a is equal to or greater than a predetermined threshold time, the process proceeds to step S36, and if not, the process proceeds to step S38.

  In step S36, the image with the longest waiting time among the uninspected images whose “waiting time” in the inspection information 32a is equal to or greater than a predetermined threshold time is set as the priority distribution image to be distributed to the interpretation terminal 106 that is the next image acquisition request source. decide.

  In step S <b> 38, it is determined whether or not the difference between the maximum value and the minimum value of the “waiting number” for the plurality of baggage imaging devices 102 is greater than or equal to a predetermined threshold number of people difference. If the difference between the maximum value and the minimum value of the “waiting number” in the number information 32b is equal to or greater than a predetermined threshold number difference, the control unit 30 shifts the process to step S40, and otherwise returns to step S44. Shift processing.

  In step S <b> 40, “waiting number of persons” in each baggage imaging apparatus 102 is referred to. The control unit 30 of the server 104 reads the “waiting number of people” in each baggage imaging apparatus 102 from the number-of-persons information 32 b stored in the storage unit 32. In step S42, the baggage imaging device 102 having the largest “waiting number” in each baggage imaging device 102 read in step S40 is determined as the priority baggage imaging device.

  In step S44, the “inspection result waiting number” in each baggage imaging apparatus 102 is referred to. The control unit 30 of the server 104 reads “the number of people waiting for the inspection result” in each baggage imaging apparatus 102 from the number-of-persons information 32 b stored in the storage unit 32. In step S46, the baggage imaging device 102 having the largest “number of people waiting for the inspection result” in each baggage imaging device 102 read in step S44 is determined as the priority baggage imaging device.

  In step S48, an image with the longest “waiting time” is determined as a priority distribution image among uninspected images in the baggage imaging device 102 determined as the priority baggage imaging device.

  In step S50, the uninspected image determined as the priority distribution image is transmitted from the server 104 to the interpretation terminal 106 that is the image acquisition request source. The control unit 30 refers to the inspection information 32a stored in the storage unit 32, reads the image ID of the uninspected image determined as the priority delivery image, and has not yet inspected the image ID assigned from the image information 32c. The image data of the image is read out and transmitted to the image interpretation request source 106 through the communication unit 38.

  Through the above processing, the package image is distributed from the server 104 to the interpretation terminal 106 that is the image acquisition request source, and the inspection of the package image at the interpretation terminal 106 becomes possible.

  Here, by determining the priority baggage imaging device according to the “number of waiting people” in steps S40 and S42, the baggage image is preferentially delivered to the image interpretation terminal 106 in order from the baggage imaging device 102 having the “number of waiting people”. be able to. Therefore, it is possible to level the number of persons inspected waiting for inspection in the plurality of baggage imaging devices 102.

  Further, when the difference between the maximum value and the minimum value of the “number of waiting persons” is smaller than the threshold number of persons in step S38, the priority baggage imaging device is determined according to the “number of inspection result waiting persons” in steps S44 and S46. The package images can be preferentially delivered to the image interpretation terminal 106 in order from the package imaging device 102 having a large number of “waiting inspection results”. In other words, if it is determined that there is no difference in level between the inspection lanes in the total number of persons waiting to be inspected (the number of persons waiting), the inspected persons who have already taken an image of the package The number of persons to be inspected waiting for the inspection result after capturing the image of the baggage can be leveled by sequentially inspecting the baggage image of the baggage imaging apparatus 102 having a large number of “waiting inspection results” indicating the number of people.

  Also, in steps S34 and S36, among the uninspected images whose “waiting time” is equal to or greater than a predetermined threshold time, an image having the largest “waiting time” is preferentially inspected, thereby enabling “waiting number of people” and “waiting for inspection results”. Regardless of the “number of persons”, the parcel image of the inspected person whose “waiting time” has become longer is given priority over the leveling process of the number of inspected persons between the inspection lanes of the plurality of parcel imaging devices 102. Priority can be given to inspection.

[Modification]
In the luggage imaging apparatus 102, the conveyance speed of the conveyance unit 12 may be controlled by the conveyance speed adjusting unit 20a according to the inspection state of the luggage. When the conveyance speed adjustment unit 20a receives the inspection result of the package from the server 104, the conveyance speed adjustment unit 20a calculates an inspection processing speed that is the number of inspection results received per unit time. The transport speed adjusting means 20a adjusts the transport speed of the package in the transport section 12 by outputting a speed adjustment signal that increases the transport speed as the inspection processing speed increases.

  With such a configuration, the conveyance speed of the conveyance unit 12 that automatically conveys the package can be increased as the package imaging device 102 in the inspection lane has a higher inspection processing speed. Accordingly, the longer the inspection lane of the queue is, the higher the inspection speed is increased by preferential inspection, and the inspection time of each inspection lane of the plurality of luggage imaging devices 102 is more effectively leveled. The deviation of the inspection time caused by the queue length can be suppressed.

  By the way, the present invention is not limited to the above-described embodiment, and may be implemented in various different embodiments within the scope of the technical idea described in the claims. The effects described in the embodiments are not limited to this.

  In the above-described embodiment, processing is performed so that an image captured by the luggage imaging apparatus 102 having a larger “waiting number” is distributed from the server 104 to the image interpretation terminal 106 with higher priority. However, the present invention is not limited to this, and processing may be performed such that an image captured by the luggage imaging apparatus 102 having a larger “number of people waiting for imaging” is more preferentially distributed from the server 104 to the image interpretation terminal 106. In other words, the “waiting number of people” in the present invention is not limited to the “waiting number of people” in the above-described embodiment, but may be “the number of waiting for imaging”. Specifically, in the distribution order determination process, in step S38, it is determined whether or not the difference between the maximum value and the minimum value of the “number of people waiting for imaging” is equal to or greater than the threshold number, and in step S40, each uninspected image is handled. The “number of people waiting for imaging” of the luggage imaging device ID to be obtained may be obtained, and processing may be performed so that the luggage imaging device having the largest “number of people waiting for imaging” is set as the priority luggage imaging device in step S42. In such other embodiments as well, the number of inspected persons waiting for an inspection in the plurality of baggage imaging apparatuses 102 can be leveled.

In the above embodiment, the server 104 includes the distribution order determining unit 30a, the elapsed time measuring unit 30b, the examination information 32a, the number of people information 32b, and the image information 32c. However, the present invention is not limited thereto, and these components may be included in any one of the baggage imaging apparatuses 102 and any one of the image interpretation terminals 106. In this case, the baggage imaging apparatus 102 and the image interpretation terminal 106 provided with these components provide a server function equivalent to the server 104 in the above embodiment on the network. The other package imaging device 102 and the interpretation terminal 106 exchange information in the same manner as when communicating with the server 104 via the network to the package imaging device 102 (or the interpretation terminal 106) having a server function.
