The display device 25 has a display means such as a display, and displays information on a vehicle, traveling, or operation.

In the operation support system 1, each function described below is realized by the processor of each of the above-mentioned devices executing a program to control each part. The operation performed by each function is also expressed as the operation performed by the processor of the device that realizes the function.
FIG. 4 shows a functional configuration realized in this embodiment. The server device 10 includes an inner detection unit 101, an outer detection unit 102, a promotion notification unit 103, a vehicle door determination unit 104, a platform door determination unit 105, and a notification information output unit 106. The vehicle device 20 includes a notification information display unit 201.

The inner detection unit 101 of the server device 10 determines whether or not there is an object in the inner area based on the image of the inner area which is a predetermined area of the platform of the station taken by the image pickup device 30, and determines that there is an object. If so, the object is detected. The outer detection unit 102 determines whether or not there is an object in the outer region, which is a region different from the inner region, based on the signal output by the object detection sensor 41, and if it is determined that there is an object, the outer detection unit 102 determines the object. Detect. The inner region and the outer region will be described with reference to FIG.

FIG. 5 shows an example of a platform on which a train is placed side by side. In FIG. 5, the home 3 seen from above vertically is shown. As shown in FIG. 5, the platform door device 40 is installed on the platform 3 along the edge 4 on the track side of the platform 3. In FIG. 5, the train 5 beside the platform 3 is shown. Each vehicle 6 of the train 5 is provided with three doors (hereinafter, each of which is referred to as a "vehicle door 7").

The platform door device 40 has a plurality of platform doors 42 and a plurality of fences 43. The plurality of platform doors 42 and the plurality of fences 43 are provided alternately along the edge 4 of the platform 3 and arranged side by side along the edge 4, and are closer to the edge 4 than the platform door device 40 and the platform door device. The platform 3 is partitioned on the side farther from the edge 4 than the 40. The plurality of platform doors 42 are provided at positions facing the vehicle doors 7 of the train 5 which is stopped and placed next to the platform 3.

The inner detection unit 101 detects an object in the inner region A1 shown in FIG. The inner region A1 is a region that is farther from the edge 4 of the platform 3 than the platform door device 40 and has a rectangular shape. An imaging device 30 is provided at each corner of the inner region A1 so as to face the center of the inner region A1. As a result, no matter where the person is in the inner region A1, the face of the person is photographed.

In this embodiment, the inner detection unit 101 detects the presence or absence of an object called a human. Specifically, the inner detection unit 101 acquires images taken by a plurality of image pickup devices 30, and detects whether or not there is a person in the inner region A1 from the acquired images. The inner detection unit 101 attempts to recognize the face shown in the image by using, for example, a well-known face recognition technique, detects that there is a person if even one face is recognized, and recognizes one face. If it is not done, it will not detect that there is a person.

The outer detection unit 102 detects an object in the outer region A2 shown in FIG. The outer region A2 is a region closer to the edge 4 of the platform 3 than the platform door device 40 and having a rectangular shape. The inner region A1 is a region along the edge 4 of the home 3 that is farther from the vehicle door 7 of the vehicle 6 that is laid alongside the home 3, and the outer region A2 is a region along the edge 4. This is the area closer to the vehicle door 7 of the vehicle 6.

The plurality of fences 43 are provided with a plurality of object detection sensors 41 so as to detect the presence or absence of an object in the outer region A2. The plurality of object detection sensors 41 are provided so that the detection range covers the entire outer region A2, and outputs signals indicating the respective detection results to the outer detection unit 102. The outer detection unit 102 acquires the detection result indicated by the output signal and detects the presence / absence of an object in the outer region A2.

For example, the outer detection unit 102 stores in advance the distance to the upper surface of the home 3 reflected in each pixel when there is no object in the outer region A2, and the pixel in which a distance shorter than the stored distance is measured is measured. Detects that there is an object at the position indicated by. The outer detection unit 102 supplies the result information indicating the detection result in the outer region A2 to the vehicle door determination unit 104 and the platform door determination unit 105. On the other hand, the inner detection unit 101 supplies the result information indicating the detection result in the inner region A1 to the promotion notification unit 103, the vehicle door determination unit 104, and the platform door determination unit 105.

After detecting an object (a person in this embodiment) in the inner region A1, the promotion notification unit 103 gives a notification to urge the rider. When the result information supplied from the inner detection unit 101 indicates that there is a person in the inner region A1, the promotion notification unit 103 outputs an audio signal indicating a guidance for urging the rider to the speaker device 50. The speaker device 50 is provided in the vicinity of the inner region A1 and outputs the guidance voice indicated by the input voice signal to the person in the inner region A1.

The guidance to encourage boarding is, for example, a voice saying, "The door will close soon and the vehicle will depart. It is dangerous, so those who board and disembark should move in a hurry." When such a notification is given by the promotion notification unit 103, the person in the inner region A1 tries to move from the place in a hurry, so that the object is in the inner region A1 as compared with the case where this notification is not made. It is possible to advance the timing at which it is detected that there is no such thing.

The vehicle door determination unit 104 determines whether or not the vehicle door 7 can be closed based on the detection results of the objects in each of the inner region A1 and the outer region A2. More specifically, the vehicle door determination unit 104 determines whether or not the vehicle door 7 can be closed based on the detection result of the object in the outer region A2 after a predetermined time has elapsed from the detection of the object in the inner region A1. That is, the vehicle door determination unit 104 waits for a predetermined time without performing the determination process, and performs the determination process after the elapse of the predetermined time.

Hereinafter, this predetermined time is also referred to as "waiting time". As the waiting time, for example, the maximum time required for a person to move the same distance as the width of the inner region A1 in the lateral direction is used. For example, assuming that the width of the inner region A1 in the lateral direction is 2 m and the average walking speed is 1 m / sec, the vehicle door determination unit 104 determines whether or not to close the inner region A1 with a waiting time of 2 seconds. The waiting time is not limited to this, and for example, the maximum time required to diagonally cross the inner region A1 may be used, or the waiting time is the time obtained by multiplying the maximum time by the margin rate. May be.

Specifically, when the vehicle door determination unit 104 is supplied with the result information indicating the detection result that there is a person in the inner region A1, the vehicle door determination unit 104 waits until the waiting time (for example, 2 seconds) elapses, and the waiting time elapses. The result information supplied from the outer detection unit 102 later is acquired. Further, when the vehicle door determination unit 104 is supplied with the result information indicating the detection result that there is no person in the inner region A1, the vehicle door determination unit 104 immediately acquires the result information supplied from the outer detection unit 102 without waiting. ..

When the detection result that there is no object is shown by the result information from the acquired outside detection unit 102, the vehicle door determination unit 104 determines that the vehicle door 7 can be closed, and the detection result that there is an object. When is indicated, it is determined that the vehicle door 7 cannot be closed. The vehicle door determination unit 104 repeatedly performs determination at predetermined time intervals (for example, every 0.1 seconds), and supplies the determination result to the notification information output unit 106.

The notification information output unit 106 generates notification information for notifying the supplied determination result, and outputs the generated notification information. When the determination result that the vehicle door 7 can be closed is supplied, the notification information output unit 106 generates, for example, the character string "Please close the vehicle door" as notification information and outputs it. Further, when the determination result that the vehicle door 7 cannot be closed is supplied, the notification information output unit 106 generates, for example, the character string "Please do not close the vehicle door yet" as the notification information. Output.

The notification information display unit 201 of the vehicle device 20 displays the notification information output as described above. The notification information display unit 201 displays, for example, the character string "Please close the vehicle door" when the vehicle door 7 can be closed, and "Open the vehicle door" when the vehicle door 7 cannot be closed. Do not close it yet "is displayed. The driver does not close the vehicle door 7 while "Please do not close the vehicle door yet" is displayed, and closes the vehicle door 7 when "Please close the vehicle door" is displayed. Perform the operation.

In order to avoid contact of an object with the departing vehicle 6, detection of an object in an area near the vehicle (particularly near the vehicle door 7 where the movement path of a person to the vehicle 6 is concentrated) such as the outer region A2 is detected. is important. However, it is possible that an object suddenly approaches the vehicle from a region (for example, the inner region A1) farther from the vehicle than the outer region A2, such as a rush ride. In this embodiment, as described above, the determination and notification are performed based on the detection results in the two regions, the inner region A1 and the outer region A2, so that the presence or absence of an object can be determined in the region near the door of the vehicle (this embodiment). Then, the safety at the time of departure of the vehicle can be improved as compared with the case where it is performed only in the outer region A2).

If the vehicle door 7 cannot be closed when there is an object in the inner region A1, the vehicle door 7 remains impossible to close until the object in the inner region A1 goes out. That is, even if it is detected that an object exists in the inner region A1 but the process of determining whether or not the vehicle door 7 can be closed is performed during the period until the object exits the inner region A1, it tends to be unnecessary. In this embodiment, when it is detected that there is an object (there is a person) in the inner region A1, it is determined that the vehicle door 7 is closed after a predetermined time has elapsed.

As a result, the load of the process of determining whether or not the vehicle door 7 can be closed (mainly the load on the processor of the server device 10) can be reduced as compared with the case where the standby for a predetermined time is not performed. Further, in this embodiment, when it is detected that there is no person in the inner region A1, the detection result in the outer region A2 is immediately acquired without waiting, and determination and notification are performed. As a result, the departure of the vehicle 6 can be accelerated as compared with the case where the vehicle always waits when it is detected that there is no person in the inner region A1.

The platform door determination unit 105 determines whether or not the platform door 42 of the platform door device 40 installed in the outer region A2 can be closed based on the detection result of the object in the inner region A1. In the present embodiment, the platform door determination unit 105 of the platform door 42, like the vehicle door determination unit 104, is based on the detection result of the object in the outer region A2 after a lapse of a predetermined time from the detection of the object in the inner region A1. Determine if it can be closed.

When the platform door determination unit 105 is supplied with the result information indicating the detection result that there is no person in the inner region A1, the platform door determination unit 105 immediately acquires the result information supplied from the outer detection unit 102. When the detection result that there is no object is shown by the result information from the acquired outside detection unit 102, the platform door determination unit 105 determines that the platform door 42 can be closed, and the detection result that there is an object. If is indicated, it is determined that the platform door 42 cannot be closed.

The platform door determination unit 105 repeatedly performs determination at predetermined time intervals (for example, every 0.1 seconds), and supplies the determination result to the notification information output unit 106. The notification information output unit 106 generates notification information for notifying the supplied determination result, and outputs the generated notification information, as in the case of the vehicle door. When the determination result that the platform door 42 can be closed is supplied, the notification information output unit 106 generates, for example, the character string "Please close the platform door" as notification information and outputs it.

Further, when the determination result that the platform door 42 cannot be closed is supplied, the notification information output unit 106 generates, for example, the character string "Please do not close the platform door yet" as the notification information. Output. The notification information display unit 201 of the vehicle device 20 displays the notification information output as described above. By performing the determination and notification as described above, the platform door 42 can be safely closed as compared with the case where it is not determined whether or not the platform door 42 can be closed.

The server device 10 performs a closing confirmation process for confirming whether or not the doors (vehicle door 7 and platform door 42) may be closed according to the above configuration.
FIG. 6 shows an example of an operation procedure in the closure confirmation process. First, the server device 10 (inside detection unit 101) determines the presence or absence of an object in the inner region A1 based on the image of the inner region A1 captured by the image pickup device 30 (step S11).

Next, the server device 10 determines whether or not an object has been detected in the inner region A1 in step S11 (step S12). When it is determined that the object is detected (YES) in step S12, first, the server device 10 (promotion notification unit 103) gives a notification prompting the ride (step S13). Subsequently, the server device 10 (outside detection unit 102) waits until a predetermined time elapses (step S14), and determines whether or not there is an object in the outer region A2 after the elapse of the predetermined time (step S15).

If it is determined in step S12 that no object has been detected (NO), the server device 10 (outside detection unit 102) proceeds to step S15 to determine whether or not there is an object in the outer region A2. Next, the server device 10 determines whether or not an object has been detected in the outer region A2 in step S15 (step S16).

When it is determined that the object is detected (YES) in step S16, the server device 10 (vehicle door determination unit 104 and platform door determination unit 105) cannot close the doors (vehicle door 7 and platform door 42). It is determined that there is (step S21). Then, the server device 10 (notification information output unit 106) outputs the notification information for notifying the determination result that the closure is not possible to the vehicle device 20 (step S22). After step S22, the server device 10 returns to step S11 and operates.

When it is determined in step S16 that no object is detected (NO), the server device 10 (vehicle door determination unit 104 and platform door determination unit 105) can close the doors (vehicle door 7 and platform door 42). (Step S31). Then, the server device 10 (notification information output unit 106) outputs the notification information for notifying the determination result that the closure is possible to the vehicle device 20 (step S32). The server device 10 ends this operation procedure after step S32.

[2] Modifications The above-mentioned examples are merely examples of the implementation of the present invention, and may be modified as follows. Moreover, you may combine Examples and each modification as needed.

[2-1] Notification method The operation support system 1 may notify the determination result of whether or not the doors (vehicle door 7 and platform door 42) can be closed by a method different from that of the embodiment. For example, in the embodiment, the notification is performed by displaying the notification information by the vehicle device 20, but in addition to or instead of the notification, the vehicle device 20 outputs a voice indicating the notification information to perform the notification. You may.

Further, in the embodiment, the notification information is output to the vehicle device 20, but the present invention is not limited to this. For example, when the home or platform door device 40 is provided with an image or audio output device (for example, a display or a speaker), the notification information output unit 106 outputs the notification information to the output device to perform notification. You may be broken. In short, as long as the notification information is notified to a person (for example, a driver) who operates to close the vehicle door 7 and the platform door 42, the notification may be performed by any method.

[2-2] Standby Time In the embodiment, the vehicle door determination unit 104 detects an object in the outer region A2 after a predetermined time (= standby time) has elapsed from the detection of the object in the inner region A1 based on the detection result of the vehicle door. Although it is determined whether or not the 7 can be closed, the waiting time may be changed depending on the situation.

In this modification, the vehicle door determination unit 104 determines the waiting time according to the number of objects detected in the inner region A1. The vehicle door determination unit 104 uses, for example, a waiting time table in which the number of objects and the waiting time are associated with each other.
FIG. 7 shows an example of a waiting time table. In the example of FIG. 7A, the waiting time of "T1", "T2", and "T3" is associated with the number of objects of "less than Th1", "Th1 or more and less than Th2", and "Th2 or more". (T1 <T2 <T3).

In this modification, the inner detection unit 101 supplies, for example, the number of faces recognized in the inner region A1 to the vehicle door determination unit 104 as the number of detected objects. The vehicle door determination unit 104 specifies a waiting time (for example, waiting time T3 if the number of objects is Th2 or more) associated with the number of supplied objects in the waiting time table, and waits for the specified waiting time. Then make a judgment.

In the example of FIG. 7A, the vehicle door determination unit 104 increases the waiting time as the number of detected objects in the inner region A1 increases. The larger the number of objects detected in the inner region A1, the more crowded the home is, and the more crowded the home is, the longer it tends to take time for people to disappear from the inner region A1. Therefore, if the waiting time is lengthened as the number of detected objects is increased, unnecessary determination processing performed from the inner region A1 until the person disappears is reduced.

On the other hand, if the waiting time is always long, even if the platform is vacant, the waiting time will be long and the departure will be delayed. In this modification, by varying the standby time according to the number of detected objects, the load due to unnecessary determination processing (mainly the load on the processor of the server device 10) is reduced as compared with the case where the standby time is constant. The departure time can be made as early as possible while reducing the number.

In addition to the above, the vehicle door determination unit 104 may determine the waiting time according to the moving direction of the object detected in the inner region A1. The vehicle door determination unit 104 uses, for example, a waiting time table in which the moving direction of an object and the waiting time are associated with each other.
FIG. 7B shows another example of the waiting time table. In the example of FIG. 7B, the waiting times of "T11" and "T12" are associated with the moving directions of the objects called "boarding direction" and "getting off direction" (T11 <T12). ..

The boarding direction is a direction in which the person occupying the vehicle 6 moves, that is, a direction toward the vehicle door 7 of the vehicle 6. On the contrary, the disembarkation direction is the direction in which the person disembarking from the vehicle 6 moves, that is, the direction in which the person disembarking from the vehicle 6 moves away from the vehicle door 7. In this modification, the inner detection unit 101 repeatedly supplies the position of the detected object to the vehicle door determination unit 104 at predetermined time intervals (for example, every 0.1 seconds).

The vehicle door determination unit 104 specifies the moving direction from the direction in which the supplied position changes. For example, when the object does not exist at the position of the object at the time t1 (the position before the movement) at the next time t2, the vehicle door determination unit 104 moves to the position closest to the position before the movement at the time t2. As the position of, the movement direction is specified based on the direction from the position before the movement to the position after the movement.

The vehicle door determination unit 104 compares the angle formed by the direction from the position before the movement to the position after the movement and the boarding direction, and the angle formed by the direction from the position before the movement toward the position after the movement and the disembarkation direction. , Specify the direction of a small angle as the moving direction. When a plurality of objects are detected and the boarding direction and the disembarking direction coexist, the vehicle door determination unit 104 specifies, for example, the direction in which the number of moving objects is large as the moving direction.

The vehicle door determination unit 104 specifies the waiting time associated with the specified moving direction in the waiting time table (for example, the waiting time T11 if the moving direction is the riding direction), and waits for the specified waiting time. Make a judgment. In the example of FIG. 7B, the vehicle door determination unit 104 has a longer waiting time in the getting-off direction than the waiting time in the getting-on direction. Generally, people waiting at the platform get on after the passengers get off, so there are more people from the inner area A1 in the situation where there are more people getting off than in the situation where there are more people getting on. The time required to run out tends to be short.

The larger the number of objects detected in the inner region A1, the more crowded the home is, and the more crowded the home is, the longer it tends to take time for people to disappear from the inner region A1. Therefore, if the waiting time when the getting-off direction is specified is longer than the waiting time when the boarding direction is specified, unnecessary determination processing performed until the person disappears from the inner region A1 is reduced.

On the other hand, if the waiting time is always long, even if the platform is vacant, the waiting time will be long and the departure will be delayed. In this modification, by changing the standby time according to the movement direction of the detected object, the load due to unnecessary determination processing (mainly the load on the processor of the server device 10) is compared with the case where the standby time is constant. The departure time can be made as early as possible while reducing the number of passengers.

In addition to the above, the vehicle door determination unit 104 may determine the waiting time according to the moving speed of the object detected in the inner region A1. The vehicle door determination unit 104 uses, for example, a waiting time table in which the moving speed of an object and the waiting time are associated with each other.
FIG. 7 (c) shows another example of the waiting time table. In the example of FIG. 7 (c), the waiting time of "T21", "T22" and "T23" corresponds to the moving speed of the object "less than Th21", "Th21 or more and less than Th22" and "Th22 or more". It is attached (T21>T22> T23).

In this modification, the inner detection unit 101 repeats the position of the detected object at predetermined time intervals (for example, every 0.1 seconds) and supplies the detected object to the vehicle door determination unit 104, as in the example of FIG. 7B. do. The vehicle door determination unit 104 calculates the moving speed based on the amount of change in the supplied position. The vehicle door determination unit 104 specifies a waiting time (for example, if the moving speed of the object is less than Th21 and Th22 or more, the waiting time T22) associated with the calculated moving speed of the object in the waiting time table, and the specified waiting time is specified. Make a judgment after waiting for a time.

In the example of FIG. 7C, the vehicle door determination unit 104 increases the waiting time as the moving speed of the object detected in the inner region A1 is slower. The slower the moving speed of the detected object, the longer it tends to take for the inner region A1 to disappear. Therefore, if the waiting time is lengthened as the moving speed of the detected object is slower, unnecessary determination processing performed from the inner region A1 until the person disappears is reduced.

On the other hand, if the waiting time is always long, even if the platform is vacant, the waiting time will be long and the departure will be delayed. In this modification, by changing the standby time according to the movement speed of the detected object, the load due to unnecessary determination processing (mainly the load on the processor of the server device 10) is compared with the case where the standby time is constant. The departure time can be made as early as possible while reducing the number of passengers.

The vehicle door determination unit 104 may specify the waiting time by using two or more of the number of detected objects, the moving direction of the detected objects, and the moving speed of the detected objects. When the number of objects and the moving direction of the objects are used, for example, the vehicle door determination unit 104 specifies the waiting time by the method described in FIG. 7, and sets the average of the two specified waiting times as the waiting time. This makes it possible to reduce unnecessary determination processing as compared with the case where only one of the number of objects, the moving direction, and the moving speed is used.

[2-3] Platform door determination method The platform door determination unit 105, like the vehicle door determination unit 104, is based on the number of detected objects, the movement direction of the detected objects, and the movement speed of the detected objects. The determination may be made after waiting for the specified waiting time. As a result, the load of the process of determining whether or not the platform door 42 can be closed can be reduced as compared with the case where the waiting time is constant.

Further, the platform door determination unit 105 may specify a waiting time different from that of the vehicle door determination unit 104. For example, the vehicle door determination unit 104 specifies the waiting time based on the number of detected objects, and the platform door determination unit 105 specifies the waiting time based on the movement direction of the detected objects.

[2-4] Standby time, presence / absence of platform door The vehicle door determination unit 104 and the platform door determination unit 105 may make a determination without providing a standby time. Even in that case, the safety at the time of departure of the vehicle can be enhanced as compared with the case where the determination of the presence or absence of an object is performed only in the region near the door of the vehicle (for example, the outer region A2). Further, the platform may not be provided with a platform door device. Even in that case, by detecting the presence or absence of an object in each of the two regions, the inner region A1 and the outer region A2, the safety at the time of departure of the vehicle is compared with the case where the presence or absence of the object is determined in only one region. It is possible to accelerate the departure of the vehicle while increasing the number of vehicles.

[2-5] Functional configuration The functional configuration realized by the server device 10 and the vehicle device 20 is not limited to that shown in FIG. For example, in the embodiment, the notification information output unit 106 performs an operation of generating the notification information and an operation of outputting the generated notification information, but these operations may be performed by different functions.

Further, for example, one function may perform the operation performed by the inner detection unit 101 and the outer detection unit 102. Further, the functions realized by the server device 10 may be realized by computer resources provided by two or more information processing devices or cloud services. In short, as long as the functions shown in FIG. 4 and the like are realized as a whole, the range of operations performed by each function and the device that realizes each function may be freely determined.
