Abstract
A surveying instrument comprises a distance measuring light projecting module, a light receiving module, an optical axis deflector which integrally deflects a distance measuring optical axis and a light receiving optical axis, a wide-angle image pickup module, a projecting direction detecting module configured to detect an optical axis deflection angle and a deflecting direction, a narrow-angle image pickup module, a distance measurement calculating module and an arithmetic control module, wherein the arithmetic control module is configured to control the optical axis deflector and the distance measurement calculating module, wherein the distance measurement calculating module is configured to perform a distance measurement of a measuring point based on a light emission timing of a distance measuring light and a light reception timing of a reflected distance measuring light, and wherein the narrow-angle image pickup module is configured to acquire a narrow-angle image with the distance measuring optical axis as an image center.
