Abstract: A method for discriminating the moving object type comprises steps: making the moving object drive the passage; measuring the velocity of the moving object; emitting light from one side of the passage; receiving the light which is not blocked by the moving object from the other side of the passage; detecting the profile of the moving object based on the emitted light and measured velocity of the moving object to detect at least part of the profile of the moving object; and a discriminating step, which compares at least part of the profile with the information stored predetermined so as to determine the type of the moving object.
