Abstract: The present disclosure relates to a target tracking method, apparatus, device and a medium. The target tracking method includes: acquiring a target video, where the target video includes a first image frame and a first subsequent image frame sequence after and adjacent to the first image frame; performing polygon detection on the first image frame to obtain each vertex of a target polygon; and tracking each vertex of the target polygon in the first subsequent image frame sequence according to a first vertex position of each vertex of the target polygon in the first image frame. According to embodiments of the present disclosure, real-time performance and accuracy of tracking the target polygon can be improved.

Abstract: The present disclosure relates to a target tracking method and apparatus, a device, and a medium. The method includes: acquiring a target video frame; determining, based on the target video frame, position information of a target area in the target video frame; in a case that a determination of the position information of the target area in the target video frame is failed, determining target photographing position information, and determining again, according to the target photographing position information and a camera projection algorithm, the position information of the target area in the target video frame.
