Abstract

A speed limit violation control system of the present disclosure includes: imaging units (320, 330) which image a running vehicle; recorder (420) that records one of videos imaged by the imaging units (320, 330); and controller (360) that calculates a speed of the vehicle based on the videos of imaging units (320, 330) and determines a starting point and an ending point of the one of the videos, which is to be recorded in recorder (420), based on the calculated speed.

Claims

1. A speed limit violation control system comprising:

an imaging unit that images a running vehicle to provide a video;

a recorder that records a portion of the video, the portion of the video being defined by a starting point for recording and an ending point for recording; and

a controller that

calculates a speed of the vehicle based on the video provided by the imaging unit, and

determines the starting point for recording and the ending point for recording of the portion of the video recorded by the recorder, based on the calculated speed,

wherein the controller determines the starting point and the ending point such that a period from the starting point to the ending point includes a period from when the speed of the vehicle exceeds a set reference value until when the speed of the vehicle falls down to the reference value or less.

2. The speed limit violation control system according to claim 1, wherein

the vehicle includes a first vehicle and a second vehicle, and

the controller determines the starting point and the ending point based on the speeds of the first vehicle and the second vehicle.

3. The speed limit violation control system according to claim 1, wherein the controller sets the starting point so as to be before a time when the speed of the vehicle exceeds the reference value.

4. The speed limit violation control system according to claim 1, wherein the controller sets the ending point so as to be after a time when the speed of the vehicle falls down to the reference value or less.

5. The speed limit violation control system according to claim 1, further comprising a global positioning system (GPS) unit that detects position information,

wherein the recorder records the position information, and a time when the video is imaged in association with the portion of the video.

6. The speed limit violation control system according to claim 1, wherein the recorder records time information in a file different from a file for the portion of the video, the time information relating to timing when the speed of the vehicle exceeds the reference value and timing when the speed of the vehicle falls down to the reference value or less.

7. A speed limit violation control system comprising:

an imaging unit that images a video of a first vehicle and a second vehicle, which are running and are taken as subjects;

an input unit that receives a first speed of the first vehicle, a second speed of the second vehicle, position information including geospatial data acquired by an own vehicle and speed limit information corresponding to the position information; and

a recorder that records a superimposed video obtained by superimposing the first speed, the second speed, the position information including geospatial data and the speed limit information on the video.
