PURPOSE:To efficiently obtain the rotary angle of an object to be recognized, by regulating a standard vector that connects the center of gravity to a prescribed position, and finding an angular relation between the vector that connects the center of gravity of the object to be recognized to the prescribed position, and the standard vector. CONSTITUTION:In the object to be recognized at a standard position, the standard vector that connects the center of gravity to the prescribed position is regulated. Similarly, the center of gravity, and the prescribed position for a recognizing object are found, and and the vector that connects the center of gravity to the prescribed position is found. The rotary angle of the object to be recognized can be obtained from the angular relation between the vector and the standard vector. By the above processing procedure, it is possible to make unnecessary a long time calculation of gravity.
