METHOD AND DEVICE FOR MEASURING SURFACE MOVEMENT OF OBJECT, AND COMPUTER-READABLE RECORDING MEDIUM WITH PROGRAM FOR OPERATING COMPUTER STORING PROGRAM FOR OPERATING COMPUTER FOR REALIZING THE METHOD STORED THEREON

摘要

PROBLEM TO BE SOLVED: To surely extract in read-time quantitative information concerning the surface movement of an object of a person, etc., from a video image. ;SOLUTION: A surface movement measuring method includes a step for expressing the position of the surface of the object of a first frame by a mesh model, a step for converting images in the first and second frames to plural sub-band images by plural kinds of resolutions, a step 130 for generating plural rough mesh models of node density lower than that of the mesh model, a step 132 for obtaining an overlay image obtained by overlapping the corresponding rough mesh model to each sub-band image of the first and second frames, and a step 136 for calculating the cross correlation of the texture map of the overlay image from the corresponding sub-band image of the first and second frames and calculating relative positional variation from the first frame to the second frame of each node.;COPYRIGHT: (C)2001,JPO
