Title:
MULTI-TARGET TRACKING METHOD AND DEVICE, COMPUTER DEVICE AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/151166
Kind Code:
A1
Abstract:
A multi-target tracking method and device, a computer device and a non-volatile readable storage medium. The multi-target tracking method comprises: detecting a target of a pre-determined type in an image by means of a target detector, so as to obtain target frames of the target of a pre-determined type; scoring the target frames by means of a target classifier, so as to obtain scores indicating that the target frames belong to a designated target; deleting, from the target frames, a target frame with a score lower than a pre-set threshold, so as to obtain a filtered target frame; extracting features of the filtered target frame by means of a feature extractor, so as to obtain a feature vector of the filtered target frame; and and matching, according to the feature vector, the filtered target frame with each target frame in the previous frame image of the image, so as to obtain an updated target frame.
The present application solves the problem of the dependency on a target detector in existing multi-target tracking solutions, and improves the tracking accuracy and robustness.
