Surveying instrument

Abstract

A surveying instrument has a surveying instrument main body (3) accommodating a distance measuring light projecting module (23) having a light emitter (28) for projecting a distance measuring light (35) to an object, a distance measuring light receiving module (24) having a photodetector (39) for receiving a reflected distance measuring light (45) from the object, a wide angle camera (21) for acquiring an image with a predetermined angle of view, and an arithmetic control module for controlling the distance measuring light projecting module and the wide angle camera and for calculating a distance to the object based on a light receiving result of the reflected distance measuring light with respect to the photodetector, wherein the wide angle camera has an imaging optical axis (53) tilted in a direction separated from an optical axis (27) of the distance measuring light and a deflection optical member for deflecting an optical axis of an incident background light (61) in a direction separated from the optical axis of the distance measuring light, and the imaging optical axis is configured such that a machine center (30) of the surveying instrument main body is located on a substantial extension line.
