摘要： A 3-D coordinate measurement is performed in such a way that an electrooptical distance-measuring device is used to measure a linear distance to a target point set on a surface of a measurement object, an angle measuring device is used to measure shifted angles of an optical axis of the electrooptical distance-measuring device, and a 3-D coordinate of the target point is measured according to a measured distance and a measured angle after the optical axis of the electrooptical distance-measuring device has been aligned to the target point. The present method includes a coordinate recognizing step for observing a plurality of targets, recognizing a plurality of target points, and calculating approximate 3-D coordinates of the target points; a macroscopic sighting step for approximate aligning the optical axis of the electrooptical distance-measuring device; and a microscopic sighting step for aligning the optical axis of the electrooptical distance-measuring device to the one of the target points in the predetermined viewfield range.
