Abstract

An investigation assist device is connected to cameras installed at a plurality of intersections respectively. The investigation assist device has a processor and a storage that records road map information including the plurality of intersections and captured video of each camera in association with camera information and intersection information. The processor extracts camera information of intersections adjacent to a first point where an event occurred according to an information input including information on the first point and feature information of a vehicle having caused the event. The processor retrieves a vehicle satisfying the feature information of the vehicle using a captured video of a camera specified by the extracted camera information. The processor analyzes feature information of the retrieved vehicle. The processor updates feature information of the vehicle by adding the analyzed feature information of the vehicle to the feature information of the vehicle input by the information input, and stores the updated information in the storage. The processor updates detection point information of the vehicle from the information on the first point into detection point information of the retrieved vehicle, and stores the updated information in the storage.

Claims

1. An investigation assist device that is connected to cameras installed at a plurality of intersections respectively so as to communicate with the cameras, the investigation assist device comprising:

a processor; and

a storage that records road map information including the plurality of intersections and captured video of each camera in association with camera information and intersection information;

wherein the processor extracts camera information of intersections adjacent to a first point where an event occurred according to an information input including information on the first point and feature information of a vehicle having caused the event;

wherein the processor retrieves a vehicle satisfying the feature information of the vehicle using a captured video of a camera specified by the extracted camera information;

wherein the processor analyzes feature information of the retrieved vehicle;

wherein the processor updates feature information of the vehicle by adding the analyzed feature information of the vehicle to the feature information of the vehicle input by the information input, and stores the updated information in the storage,

wherein the processor updates detection point information of the vehicle from the information on the first point into detection point information of the retrieved vehicle, and stores the updated information in the storage.

2. The investigation assist device of claim 1,

wherein the processor retrieves a plurality of vehicles satisfying the feature information of the vehicle, and displays images of the retrieved vehicles on an operator terminal,

wherein the processor analyzes feature information of any one vehicle selected by the operator terminal among the displayed vehicle images, and

wherein the processor updates the detection point information of the vehicle into detection point information of any one vehicle selected by the operator terminal.

3. The investigation assist device of claim 1,

wherein whenever the detection point information of the vehicle is updated, the processor extracts camera information of intersections adjacent to a detection point specified by the updated detection point information of the vehicle.

4. The investigation assist device of claim 1,

wherein the processor sets a predetermined period as a retrieval target period for the captured video of the camera, the predetermined period containing an occurrence time of a report about the occurrence of the event or a detection time of the vehicle.

5. An investigation assist method using an investigation assist device that is connected to cameras installed at a plurality of intersections respectively so as to communicate with the cameras, the investigation assist method comprising:
