Abstract: A target device, which allows a sufficient amount of reflected light to be obtained from an end portion, is provided and includes a measurement section. In the target device, a retroreflective layer in which a plurality of retroreflective elements are arranged on the entire circumference in a circumferential direction about an axis is formed on at least part of the outer peripheral surface of the measurement section. The retroreflective layer is formed into an uneven shape in which a distance from the axis changes along the entire circumference in the circumferential direction.

Abstract: A mobile body is controlled even in a place in which a navigation signal is difficult to receive from a navigation satellite. A three-dimensional information processing unit operates a device or a functional part which measures three-dimensional coordinates of a controlled target and operates a laser scanner or a laser scanning part which obtains three-dimensional point cloud data of the target. The unit includes a positioning section that operates the device or the functional part which measures the three-dimensional coordinates, to calculate the three-dimensional coordinates, and includes a scan controlling section that obtains the three-dimensional point cloud data from the laser scanner or the laser scanning part. The unit also includes a range calculator that calculates a movable range of the target from the three-dimensional coordinates and the three-dimensional point cloud data, and includes a controlled target position calculator that calculates a position of the target in the movable range.
