AbstractThe three-dimensional real-time detection method of human hand movement image is characterized by that sticking mark point on the joint of the hand to be tested, making said hand implement various movements according to the requirements, taking human hand movement image from different angles and real-time collecting image into computer, filtering image, mapping, nonlinear transformation, fuzzy enhancement, scanning image, finding mark point, calculating two-dimensional centre coordinate of mark point, making three-dimensional reconstitution so as to obtain human hand movement image. Said invention can be used for real-time detecting and recording human hand movement locus to research its movement law and control mechanism or used in clinical research.
