An image captured by the IoT device 140 may be a still image or a moving image. Further, the IoT device 140 provides image data representing an image captured by the camera to the edge device 110 via the communication network 160. The communication network 160 may include, for example, a LAN (Local Area Network) or a wireless LAN laid in the vehicle.

The edge device 110 is a relay device (for example, a gateway) that is connected to the communication network 160 and wirelessly connected to the communication network 150. The edge device 110 mediates data communication between a device connected to the communication network 150 and a device connected to the communication network 160. The communication network 150 may be configured including the Internet, for example. The communication network 150 is connected to an external server 120 for acquiring information related to traffic accidents and disclosing it to a large number of drivers. Specific examples of the external server 120 include a traffic information server that is operated and managed by a road administrator such as a prefecture, the Ministry of Land, Infrastructure, Transport and Tourism, or a commissioned organization thereof.

The communication network 150 includes feature information (in other words, information that characterizes the event) that represents the characteristics of the image captured by the IoT device 140 when a specific event such as a traffic accident occurs is detected. A drive recorder information server 130 that acquires position information indicating the generation position and time information indicating the generation time from the edge device 110 is connected. In the present embodiment, the drive recorder information server 130 is based on the information acquired from the edge device 110, and accident summary information indicating the outline of the traffic accident that has occurred (information indicating the degree of the traffic accident that has occurred, the location and time of occurrence) ) And provided to the external server 120. As a result, a large number of drivers using the external server 120 can share information on traffic accidents. Below, it demonstrates centering on the edge device 110 and the drive recorder information server 130 which show the characteristic of this embodiment notably.

The predetermined event refers to a collision accident (that is, a traffic accident) between a vehicle on which the edge device 110 is mounted and an object such as another vehicle, a wall, or a power pole, or a person or an animal. Here, the following method can be considered as a specific method for detecting the occurrence of a traffic accident. First, for each of a plurality of types of traffic accidents, feature information extracted from an image recorded by a drive recorder at the time of the accident is stored in advance in the storage 113 as determination criterion information. Then, the detection unit 212 compares the feature information extracted by the extraction unit 211 with each of the plurality of determination criterion information, and determines that a traffic accident has occurred when the same or similar determination criterion information exists. You can do that. For the same or similar determination of feature information and determination criterion information, depending on the distance between points when the former and the latter are mapped as points in the same coordinate space (for example, multidimensional Euclidean space).

In the present embodiment, the occurrence of a predetermined event is detected based on the feature information extracted by the extraction unit 211, but the occurrence of the predetermined event is detected by performing pattern recognition on the image captured by the imaging unit 215. You may do it. In short, any mode may be used as long as a predetermined event is detected based on an image captured by the imaging unit 215. In addition, an acceleration sensor or an impact sensor is connected to the edge device 110 via the communication network 160, and a measurement result of each sensor (that is, a change in acceleration of the vehicle on which the edge device 110 is mounted or an impact applied to the vehicle). The occurrence of a traffic accident may be detected in consideration of the above.

The transmission unit 213 receives the feature information extracted by the extraction unit 211 for the image in which the predetermined event is detected, triggered by the detection unit 212 detecting a predetermined event (a traffic accident in this embodiment). Position information indicating the position at which the image was captured and time information indicating the time at which the image was captured are transmitted to the drive recorder information server 130 via the communication unit 214. In other words, the transmission unit 213 provides the feature information, the position information, and the time information to the acquisition unit of the drive recorder information server 130 via the communication network in response to the detection of the predetermined event. Interference means for interfering with the host controller of the drive recorder.

Hereinafter, a set of feature information, position information, and time information is referred to as “drive recorder information”. The position information may be acquired using GPS, a beacon of a wireless access point in the communication network 150, and the time information may be acquired using GPS or a real-time clock. Further, the communication address of the drive recorder information server 130 that is the transmission destination of the drive recorder information may be written in advance in the storage 113 or embedded in the program.

FIG. 5 is a diagram illustrating an example of a functional configuration of the drive recorder information server 130. The drive recorder information server 130 includes an acquisition unit 231, a provision unit 232, a payment unit 233, and a communication unit 234. The communication means 234 is the communication device 134 in FIG. The acquisition unit 231, the payment unit 233, and the provision unit 232 in FIG. 5 perform the calculation or communication by the processor 131 in cooperation with the program stored in the memory 132 or the storage 133 and the processor 131 that executes the program.

The acquisition unit 231 acquires drive recorder information from the edge device 110 via the communication network 150. In the present embodiment, the acquisition unit 231 acquires drive recorder information by receiving drive recorder information transmitted via the communication network 150. In the present embodiment, the drive recorder information is transmitted from the edge device 110 to the drive recorder information server 130 via the communication network 150 when the traffic accident is detected by the detection unit 212, but from the drive recorder information server 130 The drive recorder information may be acquired by polling. In this case, the acquisition unit 231 is a unit that periodically performs the polling.

The providing unit 232 generates accident summary information from the drive recorder information acquired by the acquiring unit 231 and transmits it to the external server 120. More specifically, the providing unit 232 determines the degree of a traffic accident based on the feature information included in the drive recorder information acquired by the acquiring unit 231 (a serious accident that requires subsequent vehicle closure, or the occurrence of an accident). Moderate accidents that require traffic regulation such as deceleration when passing the vicinity of the location, minor accidents that require attention to the surroundings when passing the neighborhood of the accident location, although traffic regulation is not necessary) judge.

Then, the providing unit 232 transmits the information indicating the degree of the traffic accident and the position information and time information included in the drive recorder information to the external server 120 as accident summary information. According to such an aspect, it is not necessary to determine the extent of the traffic accident on the external server 120 side, the accident summary information provided from the drive recorder information server 130 is shared as it is with many drivers, and the situation worsens. Can be prevented. In addition, as a specific method for determining the degree of traffic accident based on the feature information, determination standard information indicating the range of feature information (or typical feature information) for each degree of traffic accident is stored in the storage 133 in advance. In addition, a method of determining the degree of a traffic accident by comparing the feature information included in the drive recorder information acquired by the acquisition unit 231 and the determination criterion information is conceivable.

In the present embodiment, in the storage 133, transfer destination information (for example, a bank account number) of a vehicle manager who has signed an information provision contract with the operation manager of the drive recorder information providing system 100 is stored in the vehicle. Is stored in advance in association with the communication address of the edge device 110 mounted on the device. Then, the payment unit 233 transfers the reward to the transfer destination indicated by the transfer destination information corresponding to the communication address of the transmission source of the drive recorder information acquired by the acquisition unit 231. In addition to the transfer of the reward, a notification that the reward has been transferred may be transmitted to the information provider.

The remuneration to be paid to the sender of the drive recorder information may be calculated according to a calculation formula for consideration for providing information in a contract for information provision. Specific examples of this calculation formula include a calculation formula that increases the consideration as the rarity of feature information (for example, the severity of an accident) increases, and a calculation formula that increases the consideration as the number of times the drive recorder information is provided. It is done. According to these aspects, an incentive for providing the drive recorder information can be given to the manager of the vehicle, and the manager's interest in providing the information can be increased.

FIG. 6 is a sequence diagram showing operations of the edge device 110 and the drive recorder information server 130 included in the drive recorder information providing system 100.

Step SA100 in FIG. 6 is a process executed by the extraction unit 211 of the edge device 110. In step SA100, the extraction unit 211 analyzes the image data provided from the imaging unit 215 and extracts feature information. Step SA110 subsequent to step SA100 is processing executed by the detection unit 212 of the edge device 110. In step SA110, the detection unit 212 detects a predetermined event (traffic accident) based on the feature information provided from the extraction unit 211.

Step SA120 following step SA110 is a process executed by the transmission means 213 of the edge device 110. In step SA120, the transmission unit 213 transmits drive recorder information including the feature information extracted by the extraction unit 211 for the image in which the predetermined event is detected by the detection unit 212 to the drive recorder information server 130. The drive recorder information transmitted from the edge device 110 in this way is transmitted to the drive recorder information server 130 via the communication network 150.

As shown in FIG. 6, in the drive recorder information server 130, the process after step SB100 is executed when the drive recorder information is received via the communication network 150. Step SB100 in FIG. 6 is a process executed by the acquisition unit 231 of the drive recorder information server 130. In step SB100, the acquisition unit 231 acquires drive recorder information transmitted from the edge device 110.

Step SB110 subsequent to step SB100 is a process executed by the providing unit 232 of the drive recorder information server 130. In step SB110, the providing unit 232 transmits the accident summary information generated based on the drive recorder information acquired in step SB100 to the external server 120. The accident summary information transmitted from the drive recorder information server 130 in this way is transmitted to the external server 120 via the communication network 150. The external server 120 publishes accident summary information received via the communication network 150 (for example, posted on a predetermined web page or broadcasted on a radio or the like). As a result, many drivers share the above accident summary information, and when passing through the vicinity of the location immediately after the occurrence of the accident indicated by the accident summary information, detour to other roads according to traffic regulations. It is possible to take measures according to the degree of traffic accident that occurred, such as passing the vehicle decelerating or paying attention, and worsening the situation (occurrence of traffic congestion due to the traffic accident or secondary traffic Accidents).

Step SB120 following step SB110 is a process executed by the payment means 233 of the drive recorder information server 130. In this step SB120, the payment means 233 calculates a remuneration to be paid to the manager of the vehicle provided with the image capturing apparatus that captured the image that is the source of the information provided to the external server 120, and pays the remuneration. Thereby, an incentive for providing the drive recorder information can be given to the manager of the vehicle, and the manager's interest in providing the information can be increased. In this embodiment, the process of step SB120 is executed after the process of step SB110. However, the process of step SB120 may be executed first, and then the process of step SB110 may be executed.

As described above, according to the drive recorder information providing system 100 of the present embodiment, it is possible to acquire information on traffic accidents from a plurality of vehicles using IoT and provide it to an external system. At the same time, it becomes possible to increase the interest, motivation and motivation of the vehicle manager for providing information.

In addition, in the drive recorder information providing system 100 of the above embodiment, the image data captured by the IoT device 140 is not transmitted from the edge device 110 to the drive recorder information server 130 as it is. For this reason, according to the present embodiment, the image data captured by the IoT device 140 is transmitted to the drive recorder information server 130, and the image data is analyzed by the drive recorder information server 130. The amount of data transmitted from the edge device 110 to the drive recorder information server 130 via the network 150 can be reduced. Further, since data transmission from the edge device 110 to the drive recorder information server 130 is performed only when a predetermined event is detected, communication is performed in comparison with a mode in which data transmission from the edge device 110 to the drive recorder information server 130 is always performed. The amount of data transmitted from the edge device 110 to the drive recorder information server 130 via the network 150 can be further reduced.

Furthermore, according to the present embodiment, the processing load of the drive recorder information server 130 can be reduced and the response of the drive recorder information server 130 can be reduced as compared with the mode in which the image data is analyzed by the drive recorder information server 130. The drive recorder information server 130 is less likely to be down due to overload. Further, according to the present embodiment, it is possible to configure the drive recorder information server 130 by using an inexpensive computer device having a low processing capacity as compared with the mode in which the image data is analyzed by the drive recorder information server 130. become.

That is, according to the present embodiment, it is obtained from a plurality of vehicles using IoT while speeding up the response of the drive recorder information server 130, reducing downtime of the drive recorder information server 130, and preventing an increase in cost. Information can be processed as necessary and provided to an external system for sharing with a large number of drivers, and the vehicle manager's interest in providing information can be increased.
