[0026]
　The movement destination estimation unit 102 estimates the movement destination of the photographing target based on the moving direction of the photographing target shown in the photographing data received from the first photographing device 2. The first image capturing device 2 is, for example, the image capturing device 2 that first captures a predetermined image capturing target among the plurality of image capturing devices 2 included in the image analysis system 100.
[0027]

The second image capturing apparatus 2 is, for example, an image capturing apparatus 2 that may capture a predetermined image capturing object after the first image capturing apparatus 2 among the plurality of image capturing apparatuses 2 included in the image analysis system 100. For example, the selection unit 104 selects the second imaging device 2 based on the estimation result of the moving destination of the imaging target. Alternatively, the selection unit 104 may select the second imaging device 2 located within the imaging range including the movement destination of the imaging target based on the estimation result of the movement destination of the imaging target. In this way, the selection rule for selecting the second image capturing apparatus 2 is predetermined and given to the selecting unit 104, and the selecting unit 104 selects the second image capturing apparatus 2 according to the selection rule.
[0029]

Request) to the network control device 3.
[0030]
　The image analysis apparatus 1 having the above-described function analyzes the flow line of a person such as a suspicious person in the image capturing range of the image capturing apparatus 2 and allows the second image capturing apparatus 2 in the expected destination to allow the unit. The amount of data transmitted per hour is increased in advance before the person moves. More specifically, in the image analysis system 100 including the image analysis device 1, a certain image capturing device 2 and a candidate location of a predicted movement destination regarding a person such as a suspicious person imaged by the image capturing device 2 are captured. A plurality of photographing devices 2 are connected to the image analysis device 1. The image analysis apparatus 1 selects the image capturing apparatus 2 that captures a range having a high probability of being a destination of a suspicious person who is an image capturing target among the plurality of image capturing apparatuses 2 that capture the candidate location of the predicted destination. In short, the image analysis device 1 selects the image capturing device 2 that can image a person such as a suspicious person who is an image capturing target in the future. Then, the image analysis device 1 performs control to increase the data transmission amount per unit time allowed for the imaging device 2.
[0031]
　By performing such processing by the image analysis device 1, it is possible to control in advance to increase the amount of data transmission per unit time that is allowed by the imaging device 2 at the moving destination of a person such as a suspicious person. Thereby, even if a suspicious person is moving by a motorcycle or the like, the image analysis system 100 quickly transfers high-definition shooting data to the transfer destination such as the image analysis apparatus 1 in the moving image capturing apparatus 2 at the moving destination. Will be able to.
[0032]
　FIG. 4 is a diagram for explaining information relating to the image capturing device 2 stored in the database 6.
[0033]
　In the database 6, as shown in FIG. 4, the photographing device ID (IDentification), position information (latitude, longitude, altitude) of the photographing device, photographing direction, photographing angle, subscriber ID (IDentification), photographing range, device type Are stored in association with each other.
[0034]
　The image capturing device ID and the position information of the image capturing device 2 are information transmitted by the image capturing device 2 to the image analyzing device 1, and are stored in the database 6 by the image analyzing device 1. For example, the image capturing device 2 has a GPS (Global Positioning System) function, calculates position information of the device itself based on a signal received from a GPS satellite by the GPS function, and stores the position information and a storage unit such as a memory in advance. The information of the image capturing device ID and the device type stored in is transmitted to the image analyzing device 1. Alternatively, the position information of the image capturing device 2 may be information manually input and set in the image capturing device 2 by the administrator. Further, the image capturing device 2 includes, for example, a geomagnetic sensor and an acceleration sensor, and transmits to the image analysis device 1 information on the image capturing direction detected based on the detection value of the geomagnetic sensor and the image capturing angle detected using the acceleration sensor. .. The image analysis device 1 records the information received from the imaging device 2 in the database 6 in association with each other. Further, the image analysis device 1 receives the subscriber ID (identification information used when using the communication network) from the server of the network carrier company, and records the subscriber ID in the database 6 in association with the photographing device ID. You may do it.
[0035]
　The shooting range is defined by a plurality of pieces of latitude/longitude/altitude information, for example. The information of the photographing range is information calculated by the image analysis apparatus 1 based on the position information of the photographing device 2, the photographing direction and the photographing angle. Alternatively, the administrator may input the information of the photographing range to the image analysis device 1. The image analysis apparatus 1 may further use information such as the focal length of the image capturing apparatus 2 when calculating the image capturing range, and may calculate the image capturing range by substituting those values ​​into a mathematical formula for calculating the image capturing range, for example. .. Note that the calculation of the shooting range is not limited to being performed by the shooting range calculation unit 102, and may be executed by a device external to the image analysis system 100, and the calculated shooting range information may be input to the image analysis device 1. Good.
[0036]
　The device type information is, for example, whether the image capturing device 2 is fixedly installed (Fixed), whether it is provided in a guard vehicle (Patrol car) or a drone (Drone), and is wearable by a person. Indicates information such as whether or not When the device type of the image capturing device 2 indicates a security vehicle or a drone, the position information of the image capturing device 2 is frequently updated. The image analysis device 1 determines the photographing device 2 whose position information is frequently updated based on the device type, and transmits a confirmation request or the like for confirming the photographing state to such a photographing device 2. You may. Based on the confirmation request for confirming the photographing state, the photographing device 2 transmits the photographing state information including the position information, the photographing direction, the photographing angle and the like to the image analysis device 1. The image analysis apparatus 1 repeatedly calculates the shooting range using the position information, the shooting direction, the shooting angle, and the like included in the received shooting state information. That is, the image analysis device 1 may perform different processes depending on the device type.
[0037]
　FIG. 5 is a first diagram showing an outline of transmission of photographing data of the photographing device.
[0038]
　In FIG. 5, each of the three image capturing devices 2a, 2b, and 2c is allowed a data transmission amount of 1 Mbps from the network carrier. The three image capturing devices 2a, 2b, and 2c are the image capturing devices 2 managed by an administrator such as a security company. Here, regarding the data transmission from each of the image capturing devices 2a, 2b, and 2c to the image analysis device 1, the total data transmission amount per unit time allowed by the network carrier is 4 Mbps. In such a situation, it is assumed that one of the image capturing devices 2 tries to transmit a high quality image because a predetermined image capturing target has been captured. However, it takes time to increase the data transmission amount per unit time beyond the permissible amount, and therefore the imaging device 2 displays the imaging target due to the traffic problem due to the permissible amount of the data transmission amount setting. It is assumed that high-quality shooting data cannot be transmitted during this period. In consideration of such a situation, if the data transmission amount per unit time allowed for each of the image capturing devices 2a, 2b, and 2c is increased in advance, the band securing for transmitting such data amount is maintained. Therefore, the cost will increase.
[0039]
　FIG. 6 is a second diagram showing an outline of transmission of photographing data of the photographing device.
[0040]
　Also in FIG. 6, the photographing devices 2a, 2b, and 2c are shown. In the image analysis system 100 including the image analysis device 1 of the present embodiment, when the desired image capturing target can be captured by the image capturing device 2a, the image analyzing device 1 is estimated to be the destination of the capturing target. Alternatively, the photographing device 2c is selected. For example, when the image analyzing apparatus 1 selects the image capturing apparatus 2c which is estimated to be the moving destination as the image capturing apparatus 2c, the image analyzing apparatus 1 controls the image capturing apparatus 2c to increase the amount of image data transmission per unit time from 1 Mbps to 2 Mbps. To do.
[0041]
　FIG. 7 is a diagram showing a processing flow of the image analysis apparatus.
[0042]
　Next, a processing flow when the image analysis device 1 and another device cooperate to perform the image analysis process will be described.
[0043]
　It is assumed that the database 6 previously stores the above-described information on the photographing state regarding the photographing apparatus 2. Further, the image analysis apparatus 1 repeatedly receives from the image capturing apparatus 2 information on an image capturing state including position information, an image capturing direction, an image capturing angle, and the like. Further, the image analysis device 1 determines whether the position information, the shooting direction, and the shooting angle information included in the shooting state information received from the shooting device 2 match the information stored in the database 6. Furthermore, if they do not match, the image analysis apparatus 1 updates the information stored in the database 6 to the information newly received from the imaging apparatus 2.
[0044]
　When the information on the shooting state is updated, the shooting range calculation unit 103 calculates the shooting range by substituting the updated position information, shooting direction, and shooting angle into a mathematical formula for calculating the shooting range. The shooting range calculation unit 103 updates the information on the shooting range stored in the database 6. The image analyzer 1 updates the information as described above each time it receives the information on the photographing state from the photographing device 2.
[0045]
　In such a situation, each photographing device 2 transmits the photographing data to the image analysis device 1. The amount of image data transmitted per unit time is stored in the relay device 5. The relay device 5 manages a session with the image capturing device 2, so that the image capturing data of the image capturing device 2 is transmitted within the range of the amount of image data transmitting per unit time allowed for each image capturing device 2. The image analysis device 1 receives the photographing data (step S101). The movement destination estimation unit 102 of the image analysis apparatus 1 analyzes the image included in the shooting data received from each shooting apparatus 2 and determines whether or not a person who is a shooting target has been detected (step S102).
[0046]
　It should be noted that the image capturing apparatus 2 may perform the behavior or person identification of the person who is the capturing target, and as a result, determine whether the person is the suspicious person who is the capturing target. Further, the object to be photographed is not limited to a person. The object to be photographed may be, for example, a vehicle such as an automobile, a bicycle, a motorcycle, or an animal, or an object that moves unnaturally (cardboard worn by a suspicious person, outside the photographing range of the photographing device 2). It may also be a stick inserted from.
[0047]
　The movement destination estimation unit 102 selects, from the plurality of image capturing apparatuses 2 connected to the image analyzing apparatus 1, the image capturing apparatus 2 that is the transmission source of the image capturing data that is being processed and that includes an image in which a person is detected. The destination estimation unit 102 reads the shooting state information of the shooting device 2 that is the transmission source from the information about the shooting device stored in the database 6. The movement destination estimation unit 102 estimates the movement direction of the detected person.
[0048]
　FIG. 8 is a diagram showing an outline of the estimation of the moving direction.
[0049]
　For example, the movement destination estimation unit 102 calculates the intra-image movement vector (v1) indicating the movement direction of the person in the image indicated by the photographing data, based on the position of the person shown in a plurality of continuous images included in the photographing data. To do. In addition, the movement destination estimation unit 102 uses the photographing direction (v2) included in the photographing state information of the photographing device 2 that is the transmission source of the photographing data and uses the movement direction vector in the real space corresponding to the intra-image movement vector (v1). (V3) is calculated (step S103). For example, when the shooting direction (v2) is south and the intra-image movement vector (v1) indicates the right direction of the rectangular image area, the west direction is based on these vectors as shown in FIG. This is the moving direction vector (v3).
[0050]
　The moving destination estimation unit 102 may estimate the range of the moving destination after a predetermined time according to the moving amount of the imaging target per unit time. The movement destination estimation unit 102 outputs the movement direction vector (v3) in the real space to the selection unit 104. The destination estimation unit 102 may output the destination range after a predetermined time to the selection unit 104. The movement destination estimation unit 102 may output the movement amount per unit time to the selection unit 104.
[0051]
　The selection unit 104 compares the shooting range of each shooting device 2 stored in the database 6 with the moving direction vector (v3) of the shooting target in the real space based on the position information of the sending shooting device 2. .. Based on the comparison, the selection unit 104 selects one or a plurality of second photographing devices 2 having the preceding photographing range in which the moving direction vector (v3) is facing (step S104). The selected photographing device 2 moves the photographing target, such as a person, after the photographing device 2 which is the transmission source of the photographing data including the image showing the photographing target cannot photograph the photographing target. The image capturing device 2 (second image capturing device 2) may be imaged in the future. The selection unit 104 detects the photographing device ID of the selected second photographing device 2 from the photographing device information stored in the database 6. The selection unit 104 outputs the image capturing device ID of the selected second image capturing device 2 to the band control requesting unit 105.
[0052]
　In addition to the movement direction vector (v3), the selection unit 104 may select the photographing device 2 by using the range of the movement destination after a predetermined time or the movement amount of the photographing target per unit time. Good. For example, the selection unit 104 determines whether or not the moving range after a predetermined time and the shooting range of the second shooting device 2 overlap. The predetermined time may be calculated based on the amount of movement per unit time. For example, when the movement amount per unit time is large, the predetermined time is set short, and when the movement amount per unit time is small, the predetermined time is set long. The selection unit 104 defines a range in which the shooting target is located based on the amount of movement of the shooting target per unit time, and selects one or more shooting devices 2 from the second shooting devices 2 belonging to the range. You may make it select. The selection unit 104 may end the process when the second imaging device 2 cannot be selected. Alternatively, when the selection unit 104 cannot select the second image capturing apparatus 2, the image analyzing apparatus 1 captures a person wearing a wearable camera or a drone including the image capturing apparatus 2 with the first image capturing apparatus 2. Control may be performed to instruct to move toward a shooting target such as a person.
[0053]
　The bandwidth control requesting unit 105 transmits a request for increasing the data transmission amount per unit time including the image capturing device ID of the selected image capturing device 2 to the network control device 3 (step S105). The network control device 3 outputs the photographing device ID and the increase request included in the increase request to the relay device 5. In response to the increase request, the relay device 5 rewrites the data transmission amount per unit time stored in the image capturing device 2 indicated by the image capturing device ID to the increased data transmission amount. Thereby, the relay device 5 can increase the data transmission amount of the photographing data per unit time, which is allowed by the photographing device 2 that may photograph the photographing target at the moving destination of the photographing target.
[0054]
　According to the above-described processing, the image analysis apparatus 1 and the image analysis system 100 including the image analysis apparatus 1 including the position estimated to be the moving destination of the image capturing target as the image capturing range have the allowable image capturing data per unit time. The transmission amount of is increased in advance before the object to be photographed moves. Immediately after the photographic subject such as a suspicious person is photographed, if the image quality of the photographic data is changed to a high quality in the photographic device 2 and the image analysis device 1 is attempted to transmit the image data, the transmission amount per unit time is small. Congestion may occur. In such a case, the image analysis apparatus 1 may not be able to receive the high-quality image data transmitted by the image capturing apparatus 2, but the above processing can solve such a problem.
[0055]
　Further, especially when a suspicious person is riding in a car, a motorcycle, or the like, although it is desired to analyze the high-quality image-capturing data showing the face of the suspicious person with the image analysis device 1, the suspicious person enters or leaves the photographic range. It takes a short time to get lost. Therefore, the photographing apparatus 2 which normally distributes photographing data of low image quality cannot distribute photographing data of high image quality. However, the image analysis device 1 according to the present embodiment can solve such a problem by the processing described above.
[0056]
　It should be noted that the image analysis apparatus 1 further uses information other than the moving direction of the shooting target and the position information of the moving destination when selecting the second shooting device 2 that includes the moving destination of the shooting target in the shooting range. You may make it select the imaging device 2 of 2. For example, it is assumed that the plurality of image capturing devices 2 are mounted on a security vehicle. In such a case, the image analysis device 1 further determines the congestion status of the road. The method by which the image analysis device 1 determines the congestion status is not limited. When it is determined that the congestion state of the road is equal to or higher than a predetermined degree, the image analysis device 1 is installed on the side of the road in advance based on the position of the image capturing device 2 and the position of the moving destination of the suspicious vehicle that is the image capturing target. One or a plurality of defined photographing devices 2 are selected. Then, the image analysis device 1 controls the data transmission amount so that the transmission amount of the photographing data per unit time permitted by the photographing device 2 increases. As a result, the image analysis device 1 can select the imaging device 2 in consideration of not only the position information but also the congestion situation of the road.
[0057]
　Further, the image analysis apparatus 1 may select the image capturing apparatus 2 according to the application using the captured image data to be analyzed. For example, when a suspicious individual is detected in the image data obtained from the fixedly installed imaging device 2, in order to obtain more information (clearer face image, car license plate, etc.) regarding the suspicious individual. The image analyzing apparatus 1 may select the second image capturing apparatus 2 from the mobile image capturing apparatuses 2 (wearable camera or drone). In addition, the image analysis device 1 may extend the range for selecting the imaging device 2 when there is insufficient information to predict the movement vector of the suspicious individual, grasp the surrounding map, and monitor the flow line. The mobile imaging device 2 may be selected for this purpose.
[0058]
　The monitor 7 provided in the above-described image analysis system 100 can output the received image or video when the imaging data captured by the imaging device 2 is received from the relay device 5. For example, the administrator designates the photographing device 2, and the monitor 7 outputs the image or video of the designated photographing device 2. The monitor 7 may be, for example, a mobile terminal such as a mobile phone, a tablet terminal, or a personal computer. Further, the monitor 7 may receive and display the movement direction vector (v3) of the movement target performed by the image analysis apparatus 1 and the information of the movement destination from the image analysis apparatus 1. Further, the image analysis device 1 displays image information obtained by blinking or enlarging the icon image of the photographing device 2 selected based on the moving destination of the photographing target among the icon images of the plural photographing devices 2 displayed on the map image. It may be output to the monitor 7. It should be noted that the monitor 7 may display a past video image or a video image of the image capturing device 2 other than the image capturing device 2 selected by the image analysis device 1 according to a user operation.
[0059]
　The bandwidth control requesting unit 105 of the image analyzer 1 transmits the increase in the data transmission amount per unit time before the increase after a predetermined time has passed after transmitting a request to increase the data transmission amount per unit time to the network control device 3. A reduction request for returning may be transmitted to the device. This makes it possible to reduce the bandwidth allocated to the image capturing device 2 when the image capturing device 2 is not capturing a desired image capturing target. The bandwidth control requesting unit 105 of the image analysis apparatus 1 detects the passing of a suspicious person based on the image data obtained from the image capturing apparatus 2 or obtains the user's instruction, and the allowable amount of data transmission. May be transmitted to the image capturing apparatus 2 having increased the number of the data transmission amount per unit time before the increase. The bandwidth control requesting unit 105 may have a function of returning to the data transmission amount per unit time before the increase when the above-mentioned return condition is satisfied.
[0060]
　The image analysis apparatus 1 acquires the moving direction vector (v3) from another device, instead of calculating the moving direction vector (v3) of the shooting target in its own apparatus, and based on the acquired information, the moving destination of the shooting target. It is also possible to select the imaging device 2 that is supposed to be.
[0061]
　Further, in the above-described processing, the case where the image analysis device 1 detects a shooting target reflected in the image in the shooting data has been described. However, the shooting device 2 or another device detects the shooting target in the image. Good.
[0062]
　FIG. 9 is a diagram showing the minimum configuration of the image analysis apparatus.
[0063]
　As shown in this figure, the image analysis apparatus 1 may have the functions of the selection unit 104 and the band control request unit 105. The selection unit 104 selects the second image capturing device related to the first image capturing device from the plurality of image capturing devices. The bandwidth control requesting unit 105 sends to the network control device 3 a request for changing the amount of data that can be sent by the second image capturing device.
[0064]
　Each of the above-mentioned devices has a computer system inside. A computer program for causing each device to perform the above-described processing is stored in a computer-readable storage medium of the device, and the computer of the device reads and executes the computer program, thereby Processing is performed. Here, the computer-readable storage medium refers to a magnetic disk, a magneto-optical disk, a CD-ROM (Compact Disc-Read Only Memory), a DVD-ROM (Digital Versatile Disc-Read Only Memory), a semiconductor memory, or the like. Further, this computer program may be distributed to the computer via a communication line, and the computer that receives this distribution may execute the program.
[0065]
　Further, the computer program may be a program for realizing a part of the function of each processing unit described above.
