Multi-view-angle laser radar surveying and mapping device and view angle preferential selection method thereof

Abstract

The invention provides a multi-view laser radar surveying and mapping device and a view selection method thereof. The multi-view laser radar surveying and mapping device comprises a triangular surveying and mapping base, the top of the triangular surveying and mapping base is provided with three fixing plates, and each fixing plate is provided with a surveying and mapping mechanism, an adjusting mechanism and two dismounting mechanisms; the surveying and mapping mechanism comprises a mounting block, a placement groove, a fixing block, a square plate, a laser radar body, a laser transmitter, a sensing chip, a receiving lens and a transmitting lens, the mounting block is fixedly mounted at the top of the fixing plate, and the placement groove is formed in the top of the mounting block; according to the multi-view laser radar surveying and mapping device and the view angle preferential selection method thereof, multi-view surveying and mapping can be carried out on a detection site, meanwhile, a proper surveying and mapping view angle can be selected, and a laser radar can be rapidly disassembled to be overhauled and maintained when the laser radar breaks down.

Description

technical field [0001] The invention belongs to the technical field of radar surveying and mapping, and in particular relates to a multi-view laser radar surveying and mapping device and a method for selecting a viewing angle. Background technique [0002] Lidar is a radar system that emits a laser beam to detect the position, speed and other characteristic quantities of the target. Its working principle is to transmit a detection signal to the target, and then compare the received signal reflected from the target with the transmitted signal, and make an appropriate After processing, the relevant information of the target can be obtained, such as target distance, azimuth, height, speed, attitude, and even parameters such as shape. In the prior art, a scanning control method, device, equipment and laser based on laser radar have been announced. Radar and laser radar include: a laser transmitter (1) for emitting laser light; a reflector (4) arranged on a fixed axis, the reflec...

Problems solved by technology

[0003] However, there are deficiencies in the above structure. When using laser radar for surveying and mapping, the field of view provided by a single laser radar is limited, and it is impossible to accurately survey and map the locations that need to be detected, and there is a blind spot in the detection field of view.
