VISION SENSOR SYSTEM, CONTROL METHOD, AND PROGRAM

On the basis of a measured shape, which is a three-dimensional shape of a subject measured by means of a measuring unit using an image captured when an image capturing unit is disposed in a first position and a first attitude, a movement control unit determines a second position and a second attitude for once again capturing an image of the subject, and sends an instruction to a movement mechanism. The three-dimensional shape is represented by means of height information from a reference surface. The movement control unit extracts, from the measured shape, a deficient region having deficient height information, and determines the second position and the second attitude on the basis of the height information around the deficient region of the measured shape. In this way, the position and attitude of the image capturing unit can be determined in such a way as to make it easy to eliminate the effects of shadows. 移动控制部基于测量形状来决定应再次拍摄被摄体的第二位置及第二姿势，并对移动机构作出指示，所述测量形状是使用将摄像部配置成第一位置及第一姿势时的图像通过测量部所测量的、被摄体的三维形状。三维形状是由距基准
