Abstract:
A surveying instrument for measuring three-dimensional position of a measured object, has a detecting section for detecting a direction of the measured object by rotational emission of two or more fan-shaped laser beams in which at least one beam is inclined; an optical system including a tracking-light-emitting section for emitting a tracking light and a distance-measuring-light-emitting section for emitting a distance-measuring light; a tracking-light-receiving section for receiving the tracking light reflected by the measured object; and a driving section for driving the optical system in order to collimate the measured object according to an output of the detecting section and an output of the tracking-light-receiving section.
