Abstract

An investigation assist device includes a processor and a storage that records information on a road map including a plurality of intersections and captured videos of a plurality of cameras in correlation with a capturing time, camera information, and intersection information. The processor retrieves at least one vehicle satisfying a retrieval condition and extracts a traveling direction of the vehicle when passing through each of the plurality of intersections based on the captured videos of the plurality of cameras in response to a designation of the retrieval condition including information on time when an incident occurs and feature information on a vehicle causing the incident. The processor superimposes a traveling route of the vehicle on the road map based on the traveling direction extracted for each of the intersections and outputs the traveling route to an output unit.

Claims

1. An investigation assist system, comprising:

a plurality of cameras that are installed at a plurality of intersections respectively and

an investigation assist device that is configured to communicate with the plurality of cameras,

wherein the investigation assist device comprises;

a processor; and

a storage configured to record information on a road map including the plurality of intersections and captured videos of the plurality of cameras respectively in correlation with a capturing time, camera information, and intersection information,

wherein the processor retrieves at least one vehicle satisfying a retrieval condition and extracts a traveling direction of the vehicle at each of the intersections at the time of passing through each of the plurality of intersections based on the captured videos of the plurality of cameras in response to a designation of the retrieval condition including information on date and time when an incident occurs and feature information on the vehicle causing the incident; and

wherein the processor superimposes a traveling route of the vehicle on the road map based on the traveling direction extracted for each of the intersections and outputs the traveling route on the road map to an output unit.

2. The investigation assist system according to claim 1, wherein

the processor analyzes the feature information on the vehicle passing through the intersections at which the plurality of cameras are installed, based on the captured videos of the plurality of cameras, and records analysis results in the storage for each vehicle.

3. The investigation assist system according to claim 1, wherein

the processor outputs information on each of the vehicles to the output unit when extracting a plurality of vehicles satisfying the retrieval condition by the retrieval, and extracts a traveling direction of the selected vehicle at each of the intersections at the time of passing through each of the plurality of intersections in response to a selection of information on one vehicle among the information on the vehicles.

4. The investigation assist system according to claim 1, wherein

the processor changes the retrieval condition when there is no vehicle satisfying the retrieval condition as a result of the retrieval and retrieves at least one vehicle satisfying the retrieval condition after the change.

5. An investigation assist method implemented by an investigation assist system including a plurality of cameras that are installed at a plurality of intersections respectively and an investigation assist device that is configured to communicate with the plurality of cameras, the investigation assist method comprising:
