Abstract

This application discloses a method, apparatus, device, and medium for tracking target objects in images, belonging to the field of positioning technology. The image target object tracking method includes: acquiring an image sequence; detecting a target object in each image of the image sequence to obtain first coordinate information of key points of the target object and a two-dimensional detection box including the target object; generating a two-dimensional target tracking box of the target object based on the two-dimensional detection box; generating a three-dimensional structure of the target object based on the first coordinate information and the second coordinate information of the two-dimensional target tracking box; and generating a trajectory of the target object in the image sequence based on the three-dimensional structure of the target object in each image, for tracking the target object. Through the scheme disclosed in this application, the tracking of three-dimensional objects in two-dimensional images can be achieved.
