Person tracking method, device, electronic device and computer readable medium

Abstract

The disclosure provides a person tracking method, device, electronic device and computer storage medium, belonging to the technical field of video processing. The method includes: acquiring N frames of images with a time window as a unit; acquiring a tracking path of a target person within the time window according to the N frames of images; constructing a continuous tracking path through continuous time windows to obtain a tracking result of the target person. On the basis of the existing MHT algorithm, the video containing N frames of images is processed with a global tracking scheme in units of time windows, and the tracking path of the target person in the image is obtained, and a similar real-time tracking scheme is used between time windows. Processing, this method optimizes the tracking methods of global tracking and real-time tracking in the prior art, not only can realize quasi-real-time character tracking, but also avoid the problem of exponential expansion of computing and memory as the tree depth increases.

Description

technical field [0001] The present disclosure generally relates to the technical field of video processing, and in particular, relates to a person tracking method, device, electronic device, and computer-readable medium. Background technique [0002] People tracking technology is widely used in video surveillance, and the "detection + association" scheme is often used to realize it, that is, people are detected from each frame of video images, and then these person detection frames are associated with the identities of people to achieve The purpose of tracking the trajectory of the person. [0003] According to the different tracking processing delays, people tracking technology can be divided into real-time processing and global processing. These two schemes have their own advantages and disadvantages. Although the real-time processing scheme can obtain the tracking results in real time, it has poor processing ability in solving the occlusion, intersection and long-term di...

AI Technical Summary

Problems solved by technology

These two schemes have their own advantages and disadvantages. Although the real-time processing scheme can obtain the tracking results in real time, it has poor processing ability in solving the occlusion, intersection and long-term disappearance of characters. When the judgment of a certain frame of image is wrong When , the image behind this frame cannot be corrected

Although the global processing scheme can continuously correct the errors of the previous frames during the processing process and has high fault tolerance, the processing speed is very slow, which makes it impossible to obtain the tracking results in real time.
