The invention provides a target tracking method which comprises: a step of obtaining a connected domain, carrying out three-dimensional connected domain analysis on an input initial depth image to obtain a list of the connected domain of the initial depth image; a step of determining an initial target, determining a target connected domain where the target is in the initial depth image according to a currently known current position of the target, and determining n feature points in the image part corresponding to the connected domain, wherein n is a natural number; a step of tracking, carrying out three-dimensional connected domain analysis in the subsequent depth image input after the initial depth image, identifying the target connected domain where the target is in each candidate connected domain in the connected domain list of the subsequent depth image; and a step of determining the target position, namely tracking the n feature points in the target connected domain identified by the tracking step to update the current position of the target. A target tracking device is also correspondingly provided. |
