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.
