Three-dimensional range finder and measuring and using method thereof

Abstract

The invention provides a three-dimensional range finder, which comprises: a shell; a supporting disc, wherein the shell is coaxially and rotationally arranged above the supporting disc, and a verticalpoint alignment device is fixedly arranged in the center of the bottom of the supporting disc; a reference alignment device, wherein the outer peripheral surface of the shell is fixedly provided withthe reference alignment device used for being aligned with a reference line; a distance measurement processing system comprising a data processing module, an interaction module and a distance measurement module, wherein the data processing module is electrically connected with the interaction module and the distance measurement module, and the measurement direction of the distance measurement module is perpendicular to the alignment direction of the reference alignment device; and a level adjusting device, wherein the supporting disc is provided with the level adjusting device used for keeping the shell horizontal. Through the cooperation of the reference alignment device and the level adjusting device, in combination with the arrangement that the measurement direction of the distance measurement module is perpendicular to the alignment direction of the reference alignment device, three-dimensional measurement can be accurately conducted on the distance and flatness of a to-be-measured wall, so that the measurement error is small, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of opto-mechanical-electrical integration equipment, in particular to a three-dimensional distance measuring instrument and a method for measuring and using the same. Background technique [0002] In recent years, with the development of science and technology, laser rangefinders have been increasingly used in aerospace, robotics and other fields. In order to obtain the three-dimensional environment information of the measured object, it is usually necessary to build a three-dimensional laser ranging system. [0003] However, the existing three-dimensional ranging devices have obvious errors due to the instability of the measurement base. Contents of the invention [0004] The object of the present invention is to provide a three-dimensional range finder to solve the above problems. [0005] In order to achieve the above object, the present invention provides the following technical solutions: a three-di...
