Abstract
An image target tracking method, device, and system thereof are provided in the present disclosure. The image target relative position determining method includes the following steps: obtaining a target initial position, and performing a sparse sampling according to the target initial position; dividing sampling points into foreground sampling points and background sampling points; clustering adjacent foreground sampling points according to a spatial distribution of the foreground sampling points in order to obtain a clustering result containing a plurality of clusters; and performing a robust estimation according to the clustering result in order to determine a relative position between a target and a camouflage interference in an image. Throughout the process, a multi-feature cascade clustering is completed by using sparse sampling, sampling point division, and adjacent foreground sampling point clustering; a robust estimation is performed in order to accurately predict a relative position between a target and a camouflage interference.
