The invention discloses an automatic target tracking and trajectory calculation method based on multiple videos, and belongs to the technical field of computer vision processing. The invention discloses an automatic target tracking and trajectory calculation method based on multiple videos. The method comprises the following steps of camera parameter calculation and three-dimensional reconstruction, definition and parameter training of a 3D scene model, and target person recognition and trajectory reconstruction. According to the method, the 3D models of all pedestrians in the video can be quickly reconstructed, each person and the action track of the person are parameterized by using the SPM model, comparison and registration are performed from the two aspects of appearance and posture through the calculated parameters, and recognition and path calculation of the target object are completed.
Description
technical field [0001] The invention relates to the technical field of computer vision processing, in particular to a method for automatic target tracking and trajectory calculation based on multiple videos. Background technique [0002] Target tracking and trajectory calculation have extremely important application value in criminal investigation, intelligent monitoring and intelligent transportation. The traditional method needs to search for the target object in a large amount of surveillance video and measure the behavior trajectory, which requires a lot of manpower, and there are endless errors and omissions. [0003] There are two types of methods commonly used at present: [0004] (1) Pedestrian re-identification: also known as pedestrian re-identification, is a technology that uses computer vision technology to determine whether a specific pedestrian exists in an image or a single video. However, this technology has great limitations. Firstly, it cannot track targe...
