摘要
Disclosed is a system for collecting statistics on pedestrian traffic by means of tracking based on a video analysis technique. The system comprises: a camera, a storage module, a comparison module, a positioning module, a trajectory formation module, a directional module, a counting module, a calculation module, a pre-built body recognition model and a motion trajectory, wherein the comparison module compares image information obtained by the camera with a stored body recognition model, and if comparison is successful, first-step positioning is carried out; the trajectory formation module tracks, based on the first-step positioning, recognised body image information to form a body motion trajectory in a three-dimensional space; the directional module compares the body motion trajectory with a pre-set motion trajectory in the storage module to determine the direction of the body motion trajectory; and the counting module collects statistics on pedestrian traffic according to the direction of the body motion trajectory. The system in the present invention can not only accurately recognise that there are people coming in and going out, but also determine the direction, so a false positive rate is relatively low.
