In this example, six surveillance cameras are installed per vehicle. However, as another configuration example, the number of surveillance cameras may be more or less. Similarly, the number of settings for other devices is not limited, and various numbers may be installed.

In the monitoring system of this example, equipment is also installed in the station premises and at each station platform.
FIG. 2 shows a configuration example of a station premises system of the monitoring system according to one embodiment of the present invention.
FIG. 2 shows a station premises 31, a station platform 32 (only one is illustrated), and a management room 33.

The station premises 31 (here, the area excluding the station platform 32 and the management room 33) is provided with a plurality of (in this example, two) networks SW41, 46, and each network SW41, 46 has a device. Provided connected. Specifically, for the network SW41, three monitoring cameras 42 to 44 and one display device 45 are connected, and for the network SW46, two monitoring cameras 47, 48 are provided.

In the configuration shown in FIG. 2 as well, as with the configuration shown in FIG. 1, the number of settings for each device is not limited, and various numbers may be installed.

In this example, the number of vehicles constituting the train may be arbitrary. For example, a single vehicle or a plurality of trains may be used.
FIG. 3 shows another configuration example of the in-vehicle system.
In this example, the same four vehicles A5 to A8 as those shown in FIG. 1 are further connected to the same four vehicles A1 to A4. As this connection, the network SW of the fourth vehicle A4 and the network SW of the fifth vehicle A5 are connected via a line 81.
Thus, as a vehicle organization, the number of vehicles can be easily increased or decreased by constructing one network by connecting each vehicle between the networks SW and enabling communication via the network SW.

An example of operation in the system shown in FIGS. 1 and 2 will be described.
Schematically, in the in-vehicle system, in each of the vehicles A1 to A4, each of the monitoring cameras 11 to 16 captures a video (video), the recording device 22 records the video and the like, and the display device 23 displays the video and the like. The management device 24 manages the video and the like, and the transmission device 25 wirelessly transmits and receives the video and the like via the transmission antenna 26.
In general, in the station premises system, each of the monitoring cameras 42 to 44, 47 to 48, and 52 to 54 captures images, the display devices 45, 49, and 55 display images and the like, and the management device 61 Video etc. are managed, recording device 62 records video etc., transmission device 63 wirelessly receives and transmits video etc. via transmission antenna 64, PC 71, portable terminal device 72, digital signage 73, etc. Is displayed.

A specific example of the operation will be shown.
Each surveillance camera captures an image of a target area set in advance. Video data captured by each surveillance camera is appropriately recorded inside the camera body or by a recording device. Note that the video data may be compressed, processed, or corrected by any method.
Each recorded data is transmitted to the outside by an appropriate transmission device, transmission antenna or the like. In this transmission, for example, a communication system that has already been established may be used, or another communication method may be used. As an example, a wireless LAN (Local Area Network) having a high transmission capability is used. Or the like.

Each data transmitted from the inside of the vehicle is transmitted to a recording device (for example, an archive-type recording device) installed in a management room or the like in the station when the vehicle stops or passes through the station. Each recorded data is appropriately processed to be disclosed to the outside, and then connected to an external network or a network between stations.
In addition to the video, the operation information of the existing vehicle may be recorded and transmitted in the same manner.

  Here, in the monitoring system of this example, all network devices are used, but it is not always necessary to construct a system with all network devices. For example, when the monitoring camera is not a network device, Equivalent to the monitoring system of this example by constructing the system via an encoder device that converts the video signal (video signal captured by the monitoring camera) from analog to digital and enables network distribution for connection. A system can be realized.

Hereinafter, detection of a boarding rate (a value representing a congestion situation) will be described in detail.
4 (a) and 4 (b) show examples of installation of surveillance cameras in a vehicle.
FIG. 4A shows a state in which the inside of the vehicle is viewed from above, and FIG. 4B shows a state in which the inside of the vehicle is viewed from the side. Specifically, doors 101 and 102 and seats 103 and 104 on both sides of the vehicle, and four monitoring cameras 111 to 114 provided on the ceiling of the vehicle are shown. In this example, the four monitoring cameras 111 to 114 are arranged at equal intervals, and are installed so as to take an image directly below from above.

In this way, the surveillance camera is installed at an appropriate position such as the upper part of the vehicle. Usually, it is practically difficult to monitor all of the vehicle with one surveillance camera, so a plurality of surveillance cameras are installed. And share the categories to be monitored.
As the four monitoring cameras 111 to 114 shown in FIGS. 4A and 4B, for example, the four monitoring cameras 11 to 14 in one vehicle shown in FIG. 1 are used. it can.

In this example, the boarding rate is detected based on video data captured by the monitoring cameras 111 to 114 or video data recorded in a recording device.
Specifically, for example, a person existing in the vehicle is detected based on the video data captured by the monitoring cameras 111 to 114 or the video data recorded in the recording device, and the ratio of the person to the vehicle. The occupancy rate A is determined based on whether or not In addition, the number of people getting on and off is measured based on the video data captured by the monitoring cameras 111 to 114 or the video data recorded in the recording device, and the boarding rate is determined by the number of people who are currently on the maximum number of people who can get on the vehicle. B is determined. Then, from the boarding rates calculated by these two methods, an accurate boarding rate is determined by taking an average value or the like. In this example, since a plurality of monitoring cameras 111 to 114 are assigned to the monitoring area, the results of all the monitoring cameras 111 to 114 are finally collected. Thereafter, the obtained result is displayed on a monitor (display device 23) in the vehicle or on display devices 45, 49, 55 such as an electric bulletin board or digital signage in the station premises 31 such as the station platform 32. Further, data can be transmitted and displayed on a terminal via an external network (network 65) such as a PC 71 or a terminal such as a mobile phone (mobile terminal device 72).

FIG. 5 shows an example of a processing procedure for calculating the boarding rate.
In this example, the boarding rate is calculated by the management device 24 in the vehicle A1 shown in FIG. 1, the management device 61 in the station yard 31 shown in FIG. 2, or any other device, and the vehicle shown in FIG. The information for each of the monitoring cameras 11 to 16 in A1 to A4 can be calculated by each of the monitoring cameras 11 to 16 or any other device.

This will be described with reference to FIGS. 4 (a), 4 (b) and FIG.
First, when the train operation starts (step S1), the boarding rate is cleared (initialized) (step S2).
Basically, since the change in the vehicle occupancy rate is synchronized with the opening and closing of the doors 101 and 102, the opening (opening) of the doors 101 and 102 is used as a trigger (step S3), and preparation for occupancy rate calculation (occupied person) (Preparation for detection) (step S4), detection of persons getting on and off at the same time is executed (step S5), and the detected persons getting on and off are counted (step S6).

  Using the closing of the doors 101 and 102 as a trigger (step S7), the boarding rate calculation (occupied person detection) is executed (step S8). Then, a person is detected from the video data captured by each of the monitoring cameras 111 to 114, and the ratio of the area in the vehicle occupied by the person (occupancy based on the video data of each of the monitoring cameras 111 to 114) is calculated. (Step S9) and totaling them (for example, obtaining the total occupation rate in one vehicle based on the occupation rate based on the video data of the plurality of monitoring cameras 111 to 114). Is calculated (step S10). At the same time, using the closing of the doors 101 and 102 as a trigger (step S7), the total of the monitoring cameras 111 to 114 counted in step S6 is obtained (for example, the video data of the plurality of monitoring cameras 111 to 114 is obtained). Based on the counted number of persons, the total occupancy ratio in one vehicle is obtained) and the boarding ratio B of each vehicle is calculated by comparing with the maximum number of persons who can board (step S12).

  And the corrected boarding rate is calculated by calculating | requiring the average value of boarding rate A of each vehicle calculated from the occupation rate, and boarding rate B calculated from the number of people getting on and off (step S13). In this case, the calculation may be performed by weighting one of the average values, not the average value.

Thereafter, the data of the calculated result (boarding rate) is transmitted (step S14) and displayed on a display device (for example, the display device 23 shown in FIG. 1) (step S15).
If the train operation has not ended (step S16), the process returns to the process of step S3.

  Here, various methods may be used as a method for calculating the occupancy rate based on a specific occupancy rate, and other methods include heat source detection using a far-infrared camera, reference image comparison, and specific pattern mark detection. The boarding rate may be calculated from the occupation rate.

Further, the calculation of the boarding rate B based on the specific number of passengers will be described below.
First, at the start of operation, the number of passengers is initialized as zero, and then the number of people getting on and off is executed by triggering that the door 101 and / or the door 102 are opened.
It is not always necessary to count the number of people when the door opens, but if you count the number of people based on images taken at irregular times, if there are multiple surveillance cameras, the same person will be recognized by different surveillance cameras. However, since problems such as when counting a plurality of times or when a person at the blind spot cannot be recognized occur, it is desirable to count the number of people when the door is opened.

  Next, in order to count the number of people getting on and off, a method for recognizing a person is first required. For this purpose, for example, a method of recognizing a person's face or head using face detection or contour detection can be used. Various methods have been studied and developed for video processing in this field, and a person may be recognized by any method.

  Next, there is a need for a method for determining whether the detected person gets on or off the vehicle. For this purpose, for example, by analyzing the detected motion vector of the person, it can be determined that the vehicle is moving from the inside of the vehicle to the outside of the vehicle, and it can be determined that the vehicle is getting on if it is moving from the outside of the vehicle to the inside of the vehicle. Further, if the image is taken from the diagonally upward direction in the door direction, it can be determined that the passenger is getting on when the detected person is approaching and getting off when the person is far away.

At this time, the person staying in the vehicle is excluded from the count target. This is because the number of people on board is determined by adding / subtracting the number of people who got on and off from the number of people on board immediately before.

  In addition, it is desirable that the monitoring camera to be counted counts the number of people only by the monitoring camera that captures the door direction. This is because a monitoring camera that does not capture the direction of the door on which a person gets on and off cannot count the number of people who get on and off.

Here, in the case of a train, depending on the vehicle, it is often possible to go between vehicles through the door 105 between the vehicles. The number of passengers (boarding rate B) of each vehicle also changes depending on the movement of a person between vehicles. Therefore, the number of passengers in each vehicle can be determined more accurately by detecting / counting and feeding back the inter-vehicle door 105 at any time by a monitoring camera within the angle of view. The detection method is the same as the passenger count when the door is opened, and the detection timing is different from the passenger count when the door is opened. This may be a detection trigger when the opening / closing of the inter-vehicle door 105 is notified by a sensor or the like, but it may be entered from the inter-vehicle door 105 but cannot be delayed when exiting. Therefore, it is desirable to operate the surveillance camera so that the inter-vehicle door 105 portion is always detectable.
Then, the current number of passengers is calculated by adding or subtracting the number of passengers counted from the previous number of people on board, and the ratio to the maximum number of people who can get on the vehicle is obtained. Specifically, the boarding rate B = (current number of passengers / maximum number of passengers) × 100.

FIGS. 6 to 8 (a) and (b) show examples of installation of a monitoring camera in a vehicle.
FIGS. 6 to 8 (a) show the state of the inside of the vehicle as viewed from above, and FIGS. 6 to 8 (b) show the state of the inside of the vehicle as viewed from the side. Specifically, doors 101 and 102 and seats 103 and 104 on both sides of the vehicle, and 4 to 6 surveillance cameras provided on the ceiling of the vehicle are shown.
In FIG. 6, the four monitoring cameras 201 to 204 are installed in an obliquely upward direction of the vehicle, and are installed so as to capture an image obliquely downward from above.
In FIG. 7, five monitoring cameras 301 to 305 are installed on the ceiling, the monitoring camera 301 is in the direction of the inter-vehicle door 105, the monitoring camera 302 is in the direction of the door 101, and the monitoring camera 303 is in the direction of the door 102. The monitoring camera 304 and the monitoring camera 305 are each installed so as to take an image from directly above from below.
In FIG. 8, six monitoring cameras 401 to 406 are installed on the ceiling near the seat and two on the ceiling near the door, and are installed so as to capture an image directly downward from above. Further, in this case, the monitoring camera 402 and the monitoring camera 403 are each installed so as to image directly below, but the opposite door 102 and door 101 may be installed so as to image obliquely below from above. .

  If these surveillance cameras are swivel-type panhead cameras, the imaging direction can be changed freely, such as directly below or diagonally when the door is opened or closed, and the degree of freedom in installation and operation Can be increased.

  As in this example, from images obtained from surveillance cameras installed in an arrangement as shown in FIGS. 4 (a), 4 (b) and FIGS. 6-8 (a), (b) or other arrangements, Two methods are used: a method for determining the area occupied by a person in the vehicle and converting it to a boarding rate A, and a method for counting the number of people who get on and off the vehicle and converting it from the maximum number of people that can be boarded to a boarding rate B. By calculating the average, it is possible to determine a reliable occupancy rate with more objectivity.

In addition, you may implement combining the detection (calculation) method of arbitrary boarding rates, and the installation position of arbitrary monitoring cameras. Further, a boarding rate detection (calculation) method other than the method shown in this example, or the arrangement of surveillance cameras other than the arrangement shown in this example may be used.
In addition, when there are overlapping portions in the monitoring area captured by two or more monitoring cameras, it is considered that the overlapping portions are correlated with the images captured by these two or more monitoring cameras. By using only one of the images captured by two or more surveillance cameras, or by averaging and using information obtained from images captured by two or more surveillance cameras, A boarding rate etc. can be calculated | required.

Next, with reference to FIG. 1 and FIG.
The obtained boarding rate (occupation rate × count number of people) data is temporarily stored, for example, by the monitoring cameras 11 to 16 installed in the vehicles A1 to A4, and the information is transmitted to the management device 24 of the leading vehicle A1. Is done. In the management apparatus 24, the boarding rates (occupation rate × counted number) of the monitoring cameras 11 to 16 of the vehicles A1 to A4 are totaled to obtain the current boarding rate (for example, the boarding rate for each of the vehicles A1 to A4). . Thereby, the boarding ratio of all the vehicles A1-A4 can be similarly obtained.

  The result of the boarding rate is notified to the rider and the driver through the display device 23 installed in each of the vehicles A1 to A4, and is installed in the station premises 31 such as the station platform 32 by the transmission device 25. The data is transmitted to the recording device 62 or the management device 61 and managed by an appropriate management database.

FIG. 14 shows a display example of the boarding rate as an example of information displayed on the screen of the display device 23.
As a preferred embodiment, the boarding rate is displayed in an easy-to-understand manner. Specifically, the boarding rate (for example, 120%) is displayed as a percentage on the images of the vehicles A1 to A4, and the region of the portion where the background color of the vehicle image is applied is changed according to the boarding rate. In this example, the boarding rate and the ratio of the size of the background color area to the vehicle image match, and the background color is, for example, 0% to 50% blue, 50% to 70% By making yellow, red above 70%, etc., it is possible to easily grasp the boarding rate intuitively. In addition, the traveling direction of the train (vehicle) is indicated by an arrow, the number of each vehicle is displayed in letters, and the corresponding vehicle (the vehicle) is indicated by the vehicle number for easy understanding. Add parentheses (for example, []) and change the background and outline.

Information such as images and boarding rates by the monitoring system is also displayed in the cab by a display device. For example, the display device can be a display device that allows the driver to easily check the images and information. For example, when there is a vehicle with an abnormal opening / closing of a door, it is possible to check the situation in the cab by looking at the video from a surveillance camera that can confirm the door of the vehicle. However, it is possible to grasp quickly.
In addition, by making it possible to check the display of the boarding rate and the video together, for example, it is possible to accurately alert a crowded vehicle.

  In the display device, for example, the display content of the display screen can be switched depending on the set item, such as selecting an image of a monitoring camera to be viewed by a driver or the like, or selecting a vehicle. For example, when the display device is a touch panel type, various operations such as selection and setting can be performed by touching the screen by a person, and as another example, the display device may include a mouse or a keyboard. An input device can be connected and operated by a person.

FIG. 15 shows an example of information displayed on the screen of the display device in the train cab.
In the display screen 301 of the display device of this example, the number of the selected vehicle is displayed on the display unit 311, the boarding rate of each vehicle is displayed on the display unit 312, and the monitoring camera in the vehicle is displayed on the display unit 313. The display unit 314 displays the number of the selected surveillance camera, the display unit 315 displays an operation unit on which various operations can be performed by a person, and the display unit 316 displays a plurality of operations. Information for identifying the monitoring camera selected from among the monitoring cameras is displayed, and an image captured by the selected monitoring camera is displayed on the display unit 317.

  Further, in this example, the information on the boarding rate and the like is also applied to general display devices 45, 49, 55 such as an electric bulletin board or digital signage installed in the station premises 31 such as the station platform 32 or in the elevator. Is displayed. Along with this, images of the inside of the vehicle and the station platform are simultaneously displayed so that the congestion situation can be visually confirmed. This helps the next rider and can help to reduce congestion in vehicles and stations. In addition, information such as the boarding rate can be displayed on the floor of the station platform so that it can be easily seen by those who wait at the station.

In addition, information such as a boarding rate is distributed through an external network (for example, the network 65), and is transmitted to a mobile terminal or a PC represented by a mobile phone or the like (for example, a PC 71, a mobile terminal device 72, a digital signage 73, or the like). By using it, it is possible to know in advance information such as the boarding rate of the train scheduled to be boarded and the congestion status without being in the station.
The information on the occupancy rate is recorded, for example, in the same way as video and audio data (for example, audio data accompanying the video), and is managed in a database together with information such as date and time, station, etc. Useful information for improvement activities.

As described above, in this example, a monitoring camera, a recording device such as a video, a network switch, a display device, and a management device for the inside and outside of a vehicle in a public transportation such as a bus or taxi represented by a train. In addition, the inside of the vehicle is monitored by a monitoring system composed of a transmission device, a transmission antenna, etc., and the boarding rate in the vehicle such as a train is derived based on the image obtained by the monitoring system, and various types of boarding rates, etc. By recording information (for example, along with information recorded by an existing monitoring system), it can be used as useful information, for example, in the event of an accident or when analyzing video for purposes such as crime prevention. it can.
Moreover, in this example, the boarding rate in trains etc. can be calculated | required, for example in real time, and it can help operation of trains etc. by displaying, transmitting, and recording.

  In this way, in this example, by utilizing the monitoring system, information such as the occupancy rate of each vehicle is also derived from the image captured and recorded by the surveillance camera in the vehicle, and recorded and stored at the same time. Thus, for example, useful information can be provided even in the event of an emergency.
