In the motion measurement manner of the portable body which it tries to seek motion measurement manner

摘要

PROBLEM TO BE SOLVED: To efficiently calculate position data at a measuring point at each photographing time of a moving object, and to generate a sound matched with the motion of the moving object. SOLUTION: A reference measuring point 16 and a window 17 surrounding it are set in an initial image 11 of a moving object 15, and a pixel area constituted of plural pixels corresponding to the window is set while the position is successively shifted in a retrieval range 21 of a photographed image at each time. Correlation level between the luminance distribution of each pixel area and that of the window 17 is calculated, and a pixel area with the high correlation is defined as a new window 22, and the reference measuring point 16 is made correspond to a point (a new measuring point 23) in it. The similar processing is operated also to a picture 12 of another camera, and a three-dimensional position at a measuring point is specified by a triangulation principle using each measuring point (corresponding point) on a picture at each time and the three-dimensional position of the camera itself. The motion of a moving site is specified based on the measuring point at each time and the motion data of a link between the measuring points, and a sound corresponding to it is generated.
