Abstract

The invention discloses a vehicle speed detection system based on three-dimensional modeling technology, which is characterized in that it includes: an image acquisition module, a moving object detection module, a moving object coordinate information conversion module, a moving object speed measurement module, and an information mapping module. The vehicle speed detection system based on the three-dimensional modeling technology proposed by the present invention can detect the two-dimensional coordinates of the moving vehicle and convert them into three-dimensional coordinates, and then determine the actual size of the target according to the three-dimensional coordinates, and obtain its actual spatial position, area, speed, etc. Information, realizes intelligent recognition, tracking and behavior analysis of vehicles and other targets in the video, realizes a more intuitive and three-dimensional visual effect of the monitoring area and video, improves the detection accuracy, and enhances the friendliness of user-system interaction and convenience.

Description

technical field [0001] The invention belongs to the technical field of video monitoring and relates to a vehicle speed detection system based on three-dimensional modeling technology. 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 t...
