Abstract

The invention provides a video-based vehicle detecting and tracking method and system. The method comprises the steps of inputting a video containing a vehicle; detecting the vehicle in the video by means of a detector, obtaining a detection result of the vehicle, and building an online model of the vehicle according to a first-time detection result of the vehicle; tracking the vehicle in the video, and obtaining a tracking result of the vehicle; utilizing the online model of the vehicle for respectively conducting confidence coefficient calculation on the tracking result and the detecting result of the same fame, and obtaining a final detecting and tracking result according to integration of a confidence coefficient calculation result, the tracking result and the detecting result; utilizing the final detecting and tracking result for updating the online model of the vehicle and the detector through online learning. According to the video-based vehicle detecting and tracking method and system, the problems that the vehicle deforms in the tracking process and other objects shield the vehicle are solved.

Description

technical field [0001] The present invention relates to the technical field of intelligent traffic monitoring, and more specifically, to a video-based vehicle detection and tracking method and system. Background technique [0002] With the continuous development of computer technology and image processing technology, the vehicle detection and tracking method based on video technology has become the core content and key technology of intelligent transportation system. The detection and tracking method based on video technology has fast processing speed, convenient installation and maintenance and low cost. It is lower and has a wide monitoring range, which can obtain more kinds of traffic parameters. [0003] However, the current video-based vehicle tracking technology still has the following problems: [0004] 1) Occlusion problem. The occlusion problem that often occurs between pedestrians and vehicles or vehicles at intersections is the biggest problem affecting the accu...
