APPARATUS FOR GUIDING MOVEMENT OF AN UNMANNED MOVING BODY

This invention is intended to periodically correct the position and posture of an automatically steerable unmanned moving body according to a guiding method with the aid of dead reckoning or the like. A plurality of sets of at least two ground marks (8) are placed on the movement passage of the unmanned moving body (1) in a spaced relation along a reference passage (15) and the ground marks (8) are visually recognized by means of a television camera (6) or the like mounted on the unmanned moving body. Then, the existent position and posture of the unmanned moving body (1) are detected with reference to the results of visual recognization and thereafter the position and posture of the unmanned moving body (1) which have been calculated in accordance with the aforesaid guiding method or the like are corrected in accordance with the thus detected results.
