Abstract

A method for the registration of rigid objects by attracting objects to the desired posture by appropriate forces is described. Inputs are a group of three-dimensional coordinates of the points representing an object in the initial state and in the goal state. No information on point correspondence between the initial and the goal states is given. Firstly, the object is translated from the initial position so that its centroid coincides with one of the goal position. The difference in posture of the object is corrected by rotating round the centroid by the torque which attracts it to the goal posture. We demonstrate that repulsive forces to each point of the object from all points at the goal posture, whose magnitude is the square of the distance between the points, satisfactorily produces such torque.
