Abstract

The invention discloses a method for improving static trajectory fragments in multi-target real-time trajectory tracking. The trajectory is the single-frame trajectory target B, calculate the IOU position calculation between B and the trajectory in the static path container staticPaths, and obtain the maxIOU corresponding to the largest i-th trajectory record staticPaths[i] of the IOU in it; S3, according to the current timestamp Information, update the state of the trajectory in staticPaths, judge whether it should enter the death cycle, delete the free space; S4, wait for the newly added trajectory, repeat step S1. Aiming at the position and feature constraints of the video static target, the newly added trajectory is constrained by position and feature, which effectively reduces the generation of trajectory fragments.

Description

technical field [0001] The invention relates to the fields of video analysis and multi-target track tracking, in particular to a method for improving static track fragments in multi-target real-time track tracking. Background technique [0002] Target tracking is a very important technical link in the field of video analysis. It is necessary to correlate and match the data of multiple frames before and after the track target in the video according to time, position, and feature relationship to generate the track of the target. [0003] Corresponding to the online real-time trajectory connection process, due to target detection or various reasons, the same target will generate multiple trajectory fragments; trajectory fragments are an important parameter index for multi-target trajectory connection. If there are too many trajectory fragments, the tracking experience will be greatly improved. decline in magnitude. [0004] During online real-time processing, there is no compl...
