Abstract
An object tracking method includes: obtaining a video stream acquired by a camera, and decoding the video stream to obtain a plurality of image frames; and obtaining position information of a target object in a current image frame. Obtaining the position information of the target object in the current image frame includes: performing, in response to that the current image frame is a first-type image, object detection on the current image frame to obtain the position information of the target object in the current image frame; and predicting, in response to that the current image frame is a second-type image, the position information of the target object in the current image frame based on motion vectors of a previous image frame and a position the target object in the previous image frame.
