SIX-DEGREE-OF-FREEDOM MOTION ANALYZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an analysis method analyzing the 6-degree of freedom motion of a rigid body by using image data picked up from only one direction. SOLUTION: In this analyzing method, a reference circle 10 is set in a unified body with a rigid body, a reference point 20 is formed on the circle 10, and the image of the point 20 is picked up intermittently at fine time intervals by using a fixed camera. From image data of the reference circle 10 and the reference point 20 which are obtained every moment, the center coordinate and the rotation angle of the reference circle 10 are calculated in order. Thereby 3-degree-of-freedom translation and 3-degree-of-freedom rotational motion of the rigid body are analyzed.
