description The invention relates to the technical field of real-time figure outline detection and tracking of a depth image, in particular to a figure outline quick detection and tracking method based on the depth image. The figure outline quick detection and tracking method based on the depth image is characterized by comprising a figure outline quick detection step and a figure outline mask real-time tracking step; the figure outline quick detection step comprises the steps that S1, a background region is determined through movement of a figure; S2, update is performed through a background model update strategy according to the size and the direction of a pixel value change of the depth image in the background region; and S3, a figure outline region is obtained through background deduction, and background update is performed again depending on the figure outline region; and the figure outline mask real-time tracking step comprises the steps that S4, quick partitioning is performed on a figure outline mask region based
