Abstract

The invention relates to the technical field of computers, and provides a target tracking method and device, equipment and a storage medium. The method comprises the steps: calculating the Mahalanobisdistance between each obtained original detection region and each obtained prediction target region; taking the original detection target corresponding to the mahalanobis distance with the minimum value as a basic target to be evaluated; if the number of the to-be-evaluated basic targets is more than one, taking an original detection target in the previous frame of video image corresponding to the prediction tracking target as a to-be-processed target; performing depth feature extraction on each to-be-processed target to obtain a depth feature vector of each to-be-processed target; and matching the depth feature vector of each to-be-processed target in each frame of video image with the depth feature vector of each to-be-processed target in the next frame of video image to obtain a matching result corresponding to each to-be-processed target in each frame of video image, and completing target tracking according to the matching result. The accuracy of target tracking can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a target tracking method, device, equipment and storage medium. Background technique [0002] In order to achieve target tracking, the traditional tracking target method mainly obtains the detection frame of the target object in the detector and the tracking frame in the filter, and then directly associates and matches the obtained detection frame and tracking, and according to the obtained Correlating the matching results to determine the tracking target, but this method has high computational complexity and is easily limited by the model of the filter itself. The filter model has a poor locking effect on movable targets on images with rapidly changing illumination , it is not sensitive to the extraction of color statistical features, so that the acquisition of movable targets on images with obvious illumination changes and similar background colors is not accurate eno...
