Laser distance measuring system for realizing long-distance and short-distance measurement

Abstract

The invention discloses a laser distance measuring system for realizing long-distance and short-distance measurement. The laser distance measuring system comprises a laser light source, a collimationlight source, a first transmitting lens, a second transmitting lens, a receiving lens, a prism group, an image sensor, a photosensitive element, a distance display unit and an eyepiece; distance measuring light emitted by the laser light source passes through the first emitting lens and then irradiates a measured object, collimation light emitted by the collimation light source passes through thesecond emitting lens and then irradiates the measured object, and the distance measuring light and the collimation light emitted by the measured object pass through the receiving lens and then enter the prism group. Through the prism group, the collimation light and the distance measuring light are separated, the separated collimation light enters the image sensor, the separated distance measuringlight enters the photosensitive element, and natural light sequentially penetrates through the prism group and the distance display unit to enter the eyepiece. The laser distance measuring system issimple in structure, is convenient to use, and can achieve the integrated measurement from the short-distance high-precision measurement to the long-distance measurement of a product.

Description

technical field [0001] The invention relates to a laser ranging device, in particular to a laser ranging system for realizing long-distance and short-distance measurement. Background technique [0002] The common laser range finder has long-distance measurement, generally can measure one thousand to two thousand meters, or even farther, and also has short-distance measurement, generally within tens of meters, or within a few meters. Different ranging products are selected according to different application requirements, but it is impossible to meet the precise ranging requirements for long and short distances on one product. [0003] Therefore, how to provide a laser ranging system that realizes long-distance and short-distance measurement is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] Aiming at the problems in the prior art, the present invention provides a laser ranging system for long-distance and short-distance measur...
