PURPOSE:To make it possible to measure the distance and angle by one piece of a light wave distance and angle measuring device without changing its position regardless of the presence of an obstacle, by refracting the light emitted from the light wave distance and angle measuring device by a relay device, hitting the light to a target, and receiving the reflected light through the relay device. CONSTITUTION:A reflecting mirror 18 of a relay device 12 is arranged so as to form a right angle with a light wave axis. A light beam is emitted from a light wave distance and angle measuring device 11. Based on the light beam reflected by the reflecting mirror 18, a distance l1 between the light wave distance and angle measuring device and the reflecting mirror 18 is measured in advance. Then, the reflecting mirror 18 is slanted by a specified angle, and the reflected light from a reflecting prism 21, which is attached to a target 20 is detected through the reflecting mirror 18. Then, a length (l2+l1) from the light wave distance and angle measuring device 11 to the target 20 through the reflecting mirror 18 is measured. Thereafter the distance l2 between the reflecting mirror 18 and the target 20 is obtained. Since the reflecting mirror 18 for relay is used, the measurement can be performed by one distance and angle measuring device 11 without changing the position regardless of the presence of an obstacle. |
