Abstract
A method and device for use in hand gesture recognition is applicable to image processing. The method includes: acquiring a depth map of a hand in a current image; estimating first positions of joints of the hand according to the depth map of the hand; creating a 3D point cloud of the hand according to the depth map of the hand; matching the first position of the joints of the hand and a stored 3D hand model to the 3D point cloud of the hand to obtain second positions of the joints and first degree of freedom parameters of the joints; and recognizing the hand's gestures according to the second positions of the joints and the first degree of freedom parameters of the joints. The method achieves a practical hand gesture recognition technique and recognizes hand gestures accurately.
