Abstract: A target tracking method, including: acquiring a video stream of a preset acquisition region; performing target detection on tth video frame of the video stream, and determining a first candidate box of the candidate target in the tth video frame; ranking the candidate targets, according to a confidence of the candidate target and a first intersection over union between the first candidate boxes of respective candidate targets, and determining a candidate target in at least one matched rank; performing at least one matching on the candidate target in the at least one matched rank, respectively, according to a set of trackers of the video stream in (t−1)th state and a preset matching strategy, and determining a target tracking result of the tth video frame; and determining a tracking trajectory of the target in the video stream according to the target tracking results of the T video frames.
