Abstract

The invention provides a method and system for target detection and tracking, belonging to the field of video monitoring. The method includes: training a joint model combining target detection and target tracking; processing each frame image of the video sequence at the current moment through the joint model to generate a candidate frame, the candidate frame including target coordinates and objects belonging to each category Probability; adjust the candidate frame in conjunction with the tracking segment of the previous moment relative to the current moment; generate a final detection frame based on the adjusted candidate frame to perform target detection and obtain a final detection result; and convert the final detection The result is combined with the tracking segment at the previous moment to generate the tracking segment at the current moment. The invention utilizes the tracking information to optimize the detector itself, and fuses the tracking information with the detector at an early stage, so that the detection result is more accurate.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a method and system for target detection and tracking. Background technique [0002] With the continuous development of the Internet and artificial intelligence technology, more and more fields are involved in automatic calculation and analysis, among which the field of video surveillance is one of the most important scenarios, such as for security. In video surveillance, target detection and tracking is one of the most important technologies. Among them, the detection algorithm is to find the moving target in the video frame, such as finding the target A in the 10th frame, and finding the target a in the 11th frame, and the tracking algorithm is to prove that A and a are the same target, so it can be seen that the tracking Algorithms are based on detection algorithms. [0003] However, common target detection and tracking technologies in the field of video surveillance mostly u...
