Laser scan range finding device

Abstract

The invention provides a laser scan range finding device comprising a reflector mount, a reflector, a laser emission lens, a laser sleeve, a laser emitter, a top cover, an optical filter, a core frame, a base plate, a motor stator, a motor rotor magnetic pole, a core back plate, a laser receiver array, a receiver lens, and a receiver lens mount. The laser emission lens is used for converting the first light beam emitter by the laser emitter into a parallel light beam; the parallel light beam is reflected on the reflector surface so as to form a second light beam; when the second light beam arrives a tested target object, a third light beam is formed by the surface of the object; the third light beam is focused by the receiver lens so as to form a fourth light beam entering the laser receiver array. Compared with the prior art, the single laser emitter is combined with reflector periodical vibrations so as to realize multi-line laser emission. In addition, the angle between multi-line lasers can be controlled and adjusted through software in a microprocessor, and the angle change can be easily uniformed.

Description

technical field [0001] The invention relates to robot design technology and laser scanning technology, in particular to a laser scanning distance measuring device. Background technique [0002] Laser scanning ranging technology is a method of non-contact target object scanning and ranging using collimated beams. By rotating the collimated beam (laser) used for ranging by 360°, the distance measurement in the environment can be realized. Objects are scanned and ranging, and the contour information of the environment is extracted. [0003] In the prior art, the current multi-line laser ranging technology uses multiple laser arrays to form a laser array, and the laser array emits laser light to form a multi-line laser, which is scattered through a lens at a fixed angle. The multi-line laser formed above generally has the following defects: 1) The laser is one of the core devices of the laser scanning rangefinder, and the market price is relatively expensive. The multi-line las...
