摘要： First and second flood lamp means, which are adapted to project rotary laser beams turning at a predetermined cycle, are provided at two predetermined fixed points, and first, second and third light-receiving means, which are adapted to detect the timing and height of the reception of rotary laser beams, on a moving body. The angles of rotation of these two rotary laser beams with respect to a reference direction are determined on the basis of the outputs from the first, second and third light-receiving means, and the position and height of each light-receiving means are calculated from the resultant angles of rotation. As a result, the position and angle of posture of the moving body can be determined with a high accuracy, and these data can be displayed realtime. In order to accurately measure the angles of rotation of the two rotary laser beams with respect to the reference direction, two light-receiving means are provided on the straight line connecting the first and second flood lamp means. This enables the reference direction of each rotary laser beam to be detected accurately, and the position-measurement accuracy to be improved.
