Abstract

Provided is a surveying instrument including a distance measuring light projector configured to project a distance measuring light to an object, a distance measuring light receiver having a photodetector configured to receive a reflected distance measuring light from the object, a tracking light projector configured to project a tracking light to the object, a tracking light receiver having a tracking photodetector configured to receive a reflected tracking light from the object, and an image pickup module configured to receive a background light, in which the distance measuring light projector and the tracking light projector include a first deflecting optical member, and the distance measuring light projector, the tracking light projector, and the image pickup module include a second deflecting optical member.

Description

technical field [0001] The present invention relates to a measuring device capable of acquiring three-dimensional coordinates of an object to be measured. Background technique [0002] Measuring devices such as laser scanners and total stations have light-wave distance measuring devices that detect and measure distances by prism distance measurement that uses a reflective prism as the object to be measured, or by non-prism distance measurement that does not use a reflective prism. distance to the object. [0003] A conventional measuring device includes a distance measuring unit for measuring a distance to a measurement target object, a tracking unit for tracking the measurement target object, and an imaging unit for imaging the measurement target object. However, in conventional measuring devices, in order to keep the size of the optical system small, the distance measuring unit, the tracking unit, and the imaging unit are generally arranged on different axes. [0004] Fu...
