Document Type and Number:
WIPO Patent Application WO/2022/127876
Kind Code:
A1
Abstract:
The present application is applicable to the field of video processing. Provided are a target tracking method, a computer-readable storage medium, and a computer device. The method comprises: matching a target tracking box with target candidate boxes to determine a target candidate box in best matching with the target tracking box; matching one or more remaining target candidate boxes, except for the best matching target candidate box, with a second target candidate box detected previously to determine a corresponding matching relationship; according to the best matching target candidate box and the corresponding matching relationship, obtaining distances and overlapping relationships respectively between the best matching target candidate box and the one or more remaining target candidate boxes and between the best matching target candidate box and the second target candidate box, so as to determine a shielding relationship between a target and other objects in the current video frame; and determining, according to the shielding relationship, whether to restart target tracking. According to the present invention, the robustness of long-time tracking for a single target can be improved, a wrong result due to interference of the tracking target from the other objects is avoided, and the tracking target can be ensured to be accurate to avoid false detection.
