Abstract: The present invention relates to a hand position estimation method and system for estimating a 3-dimensional hand position for quick hand movement, on the basis of domain transfer learning from a depth image to an infrared image, the hand position estimation method comprising the steps of: processing a depth image and an infrared image for hand movement; synthesizing a depth map with the infrared image by using a hand image generator (HIG), and estimating skeletal positions of hand joints from each of the depth map and an infrared map; and calculating a 3-dimensional hand position by using the skeletal positions and the center of a hand depth image.
