Abstract

The invention relates to the technical field of image processing, in particular to a target tracking method, a target tracking device, a computer readable medium and electronic equipment. The method comprises the steps of obtaining a to-be-tracked video, and performing target detection on the to-be-tracked video to obtain a key frame image containing a tracking target; performing image recognitionon the key frame image to obtain an object area containing a tracking target, and performing key point extraction on the object area to obtain key point data of the tracking target; extracting a to-be-detected image of a next frame adjacent to the key frame, and performing feature extraction on the to-be-detected image to obtain a second feature map of the to-be-detected image; inputting the second feature map and the key point data into a prediction model as input parameters to obtain corresponding prediction key point data of each key point in the to-be-detected image; and determining the tracking target in the to-be-detected image according to the predicted key point data.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an object tracking method, an object tracking device, a computer-readable medium, and an electronic device. Background technique [0002] Object tracking is one of the hotspots in the field of computer vision research, and has been widely used in many fields. Generally speaking, target tracking is to establish the positional relationship of the object to be tracked in a continuous video sequence, and obtain the complete trajectory of the object. [0003] In the prior art, optical flow method and deep learning technology have also been widely used in target tracking technology. In the target tracking scheme based on deep learning, it is generally necessary to use deep learning to train the network model in advance; when performing tracking, the features learned by the network model are directly applied to the tracking framework of correlation filtering, so a...
