Title:
METHOD AND APPARATUS FOR DETECTING MOTION INFORMATION OF TARGET, AND DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/213729
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for detecting motion information of a target, and a device and a medium. The method for detecting motion information comprises: performing target detection on a first image to obtain a detection frame of a first target; acquiring depth information of the first image in a corresponding first camera coordinate system and thus determining depth information of the detection frame of the first target, and determining first coordinates of the first target in the first camera coordinate system on the basis of the position of the detection frame of the first target in an image coordinate system and the depth information thereof; according to posture change information of a photographic apparatus, converting second coordinates of a second target in a second camera coordinate system corresponding to a second image into third coordinates in the first camera coordinate system; and determining motion information of the first target on the basis of the first coordinates and the third coordinates. By means of the technical solution provided in the embodiments of the present disclosure, a large amount of computation processing can be avoided, thereby improving the processing efficiency.
