Abstract

Provided are a target tracking method and device, the method comprising: acquiring a to-be-tracked area of a tracked target in a current frame image; determining a plurality of key points in the current frame image, and acquiring the position of each key point; based on the position of each key point, acquiring an auxiliary tracking area in the current frame image; according to a motion track in the to-be-tracked area and the auxiliary tracking area, dividing the to-be-tracked area and the auxiliary tracking area into a plurality of groups; and establishing a spatial structure model for each group, and acquiring the position of the to-be-tracked area in the next frame image according to the spatial structure model. The position of the tracked target in the to-be-tracked area in the next frame image is obtained after obtaining the position of the to-be-tracked area in the next frame image. Compared with an existing model-based target-tracking method, an embodiment of the present invention does not require offline training, thus realizing online tracking.

Description

technical field [0001] The present invention relates to the technical field of information processing, and more specifically, to a target tracking method and device. Background technique [0002] Object tracking is a basic technology for video content understanding. With the development of video processing towards intelligence, the application of object tracking is becoming more and more extensive, such as the analysis of movement patterns and traffic patterns of groups or individuals in video surveillance; in home applications In terms of somatosensory games, gesture recognition and finger tracking; in terms of news video, continuous tracking and shooting of key figures, animal population tracking and behavior analysis, etc. [0003] Among them, target tracking refers to inputting a video containing several moving objects, and outputting the position of one or more specified moving objects (tracking targets) in each frame of the video. The main method currently used in tar...
