Vehicle detection system and vehicle detection method
View Patent ↗A client terminal displays, on a display device, a visual feature of each of a plurality of vehicles passing through an intersection at a location where an incident occurred and map data indicating a passing direction of each of a plurality of vehicles passing through the intersection and sends, in response to a designation of any one of the plurality of vehicles, an instruction to set the designated vehicle as a tracking target vehicle to the server. When the instruction is received, a server specifies a camera of the intersection at which the tracking target vehicle is highly likely to enter next based on at least a current time and a passing direction of the tracking target vehicle at the intersection and sends camera information of the specified camera to the client terminal. When the camera information is received, the client terminal displays, on the display device, a position of a camera corresponding to the camera information to be superimposed on the map data identifiably.

the server is configured to, when the instruction is received, specify an entry direction at a second intersection at which the tracking target vehicle is highly likely to enter next based on at least a passing direction of the tracking target vehicle at the first intersection and send the entry direction at the second intersection to the client terminal, and
the client terminal is configured to, when the entry direction at the second intersection is received,
display, on the display device, a position of the second intersection;
automatically set the entry direction at the second intersection as a search condition of a search request to be performed on the tracking target vehicle at the second intersection; and
send the next request to the server to search vehicles passing through the second intersection based on the search request.
2. The vehicle detection system according to claim 1 ,
wherein the server is configured to store the entry direction at the second intersection in a storage as information indicating a travelling route of the tracking target vehicle.
3. The vehicle detection system according to claim 1 ,
wherein the server is configured to specify the entry direction at the second intersection at which the tracking target vehicle is highly likely to enter next, based on a current time, the passing direction of the tracking target vehicle passing at the first intersection, and a distance from the first intersection.
4. The vehicle detection system according to claim 1 ,
wherein the client terminal is configured to send an acquisition request for a captured image of a second camera at the second intersection to the server when the second camera corresponding to the entry direction at the second intersection is designated by a user's operation, and display, on the display device, the captured image of the second camera sent from the server in response to the acquisition request.
5. The vehicle detection system according to claim 4 ,
wherein the client terminal is configured to display a direction in which the tracking target vehicle enters on the display identifiably.
6. The vehicle detection system according to claim 1 ,
wherein the client terminal is configured to send the instruction to the server when map data indicating a passing direction of any one of the plurality of vehicles passing through the intersection is designated by a user's operation.
7. The vehicle detection system according to claim 1 ,
wherein the client terminal is configured to send the instruction to the server when a visual feature of any one of the plurality of vehicles is designated by a user's operation.
8. The vehicle detection system according to claim 1 ,
wherein the client terminal is configured to display, on the display device, a passing direction of the tracking target vehicle, which passes through the first intersection, to be superimposed on the map data identifiably.
9. The vehicle detection system according to claim 1 ,
wherein the client terminal is configured to display a color of an icon of a camera corresponding to the entry direction at the second intersection differently from icons of cameras other than the camera corresponding to the entry direction at the second intersection.
10. The vehicle detection system according to claim 1 ,
wherein the client terminal is configured to blink and display an icon of a camera corresponding to the entry direction at the second intersection.
11. The vehicle detection system according to claim 1 ,
wherein the client terminal is configured to display, on the display device, a visual feature of the tracking target vehicle to be superimposed on the periphery of the intersection of the map data identifiably.
12. The vehicle detection system according to claim 1 ,
wherein the server is configured to acquire road information of an area including the plurality of intersections, and specify a second camera at the second intersection where the tracking target vehicle is highly likely to enter next based on a current time, a passing direction of the tracking target vehicle passing through the first intersection, and road information of the area.
13. The vehicle detection system according to claim 12 ,
wherein the road information of the area includes traffic jam information of a road.
14. The vehicle detection system according to claim 12 ,
wherein the road information of the area includes construction information of a road.
15. The vehicle detection system according to claim 12 ,
wherein the road information of the area includes one-way traffic information of a road.
16. The vehicle detection system according to claim 1 , wherein
the client terminal is configured to send, in response to input of information including date and time and a location at which an incident occurred and a feature of a vehicle which caused the incident, an information acquisition request for a vehicle passing through the intersection at the location at the date and time to the server,
the server is configured, when the information acquisition request is received, to extract vehicle information and passing directions of a plurality of vehicles passing through the intersection at the location in association with each other using a captured image of a camera corresponding to the intersection of the location at the date and time, and send the extracted result to the client terminal, and
the client terminal is configured to display, on the display device, the visual features of the plurality of vehicles passing through the intersection at the location and passing directions of the respective vehicles in association with each other using the extracted result.
17. A vehicle detection method implemented by a vehicle detection system which includes a server connected to communicate with a plurality of cameras installed at each of a plurality of intersections and a client terminal connected to communicate with the server, the method comprising:
displaying, by the client terminal, on a display device, a visual feature of each of a plurality of vehicles passing through a first intersection at a location and map data indicating a passing direction of the each of the plurality of vehicles having passed through the first intersection, and sending, in response to a designation of any one of the plurality of vehicles, an instruction to set the designated vehicle as a tracking target vehicle to the server;
specifying, by the server when the instruction is received, an entry direction at a second intersection at which the tracking target vehicle is highly likely to enter next based on at least a passing direction of the tracking target vehicle at the first intersection and sending the entry direction at the second intersection to the client terminal; and
in response to the entry direction at the second intersection being received by the client terminal,
displaying, by the client terminal, on the display device, a position of the second intersection;
automatically setting, by the client terminal, the entry direction at the second intersection as a search condition of a search request to be performed on the tracking target vehicle at the second intersection; and
sending, by the client terminal, the next request to the server to search vehicles passing through the second intersection based on the search request.
