Abstract

The invention discloses a vehicle speed detecting device, which is characterized in that the device comprises an image obtaining module, a moving object detecting module, a moving object coordinate information converting module, a moving object speed measuring module and an information mapping module. The speed detecting device comprises an image obtaining module, a moving object detecting module,a moving object coordinate converting module, a moving object speed measuring module and an information mapping module. The speed detecting device of the invention, 2d coordinate of that moving vehicle can be detect, and converted to three-dimensional coordinates, and then the actual size of the target is determined according to the three-dimensional coordinates, Obtaining the information of theactual space position, area and speed, the intelligent recognition, tracking and behavior analysis of the vehicle and other objects in the video are realized, the visual effect of the surveillance area and the video is more intuitive and stereoscopic, the detection accuracy is improved, and the friendly and convenient interaction between the user and the system is enhanced.

Description

technical field [0001] The invention belongs to the technical field of video surveillance and relates to a vehicle speed detection device. Background technique [0002] With the development of the automobile industry and social economy, the number of automobiles is increasing day by day. With the rapid increase of the number of automobiles, traffic accidents are also occurring more and more frequently. In many traffic accidents, speeding has become one of the main causes of traffic accidents. Therefore, it is very necessary to detect the running speed of the vehicle in time. [0003] The detection of vehicles by the existing monitoring system can only obtain the two-dimensional information of the vehicle on the projection plane of the camera and the size of the target on the projection plane. The detected target information is actually the two-dimensional information of the vehicle on the projection plane of the camera, not the three-dimensional The object itself in space....
