Paired-edge based hand tracking method using depth image

摘要

The present invention relates to an edge-pair-based hand tracking method, which detects an initial hand by detecting a finger candidate using information of a pair of edge pairs in a depth image, And a hand tracking step of tracking a shape including a coordinate having a small depth change among a plurality of coordinates stored in the next frame of the frame, and judging the shape manually. The hand tracking method according to the present invention is advantageous in that initial hand detection and hand tracking are simultaneously performed while main operations of initial hand detection and hand tracking are similar to detecting edge pair groups within a region of interest, . Also, there is an advantage in that the amount of computation is small because the stored coordinates are tracked using a simple method of comparing the depth values of the current frame and the previous frame.
