Abstract

The invention provides a measuring system of a handheld laser range finder. The measuring system comprises a total station type electronic tachometer, an optical path conversion system, a guide rail, a handheld laser range finder clamping and positioning device and a total station type electronic tachometer clamping and positioning device, wherein the total station type electronic tachometer is arranged near the top end of the guide rail; the optical path conversion system is arranged on the guide rail; the handheld laser range finder clamping and positioning device is arranged at the top end of the guide rail; the total station type electronic tachometer clamping and positioning device is used for fixing the total station type electronic tachometer. The measuring system of the handheld laser range finder, provided by the invention, reduces the detection cost and guarantees the detection precision.

Description

technical field [0001] The invention relates to the field of laser measurement, in particular to a measuring system for a hand-held laser range finder. Background technique [0002] Since the middle of last century, with the continuous development of science and technology, there has been an epoch-making ranging method—electromagnetic wave ranging. Electromagnetic wave ranging has the advantages of long range, high precision, high operating efficiency, low labor intensity, and less restricted by terrain conditions, so it is quickly applied to various fields of measurement. [0003] The first hand-held laser rangefinder was born in 1992 and was first successfully developed by the Swiss Leica company. After 1995, manufacturers around the world began mass production. Hand-held laser range finder is widely used in construction, real estate, surveying and mapping industry, large-scale industrial measurement and other aspects due to its low cost, cheap price, and the ability to a...
