Portable laser radar measuring method and device

Abstract

The invention provides a portable laser radar measuring method and device. A DGPS positioning module is adopted to obtain target position parameters, an optical prism scattering scanning system is adopted to obtain target position adjustment variable parameters, an MEMS attitude sensor is adopted to obtain target angle parameters, prism rotation position angle parameters are collected, a target position parameter equation at the moment t is constructed, and a target position parameter set measured by i laser radar devices is formed. A laser radar target positioning model for maximizing the to-be-measured target under the condition of independently distributed parameter interference is constructed, and the minimum accurate solution of the positioning model for maximizing the to-be-measuredtarget is calculated; according to the invention, a portable laser radar measurement method for avoiding a least square method with a large calculated amount is adopted, and the portable laser radar measurement device adopting the method can carry out rapid modeling and display on a measurement environment in a low-light or dark state, and can dynamically transmit a measurement structure to otheruser receiving ends in real time.

Description

technical field [0001] The invention belongs to the technical field of laser radar measurement, and in particular relates to a portable laser radar measurement method and device. Background technique [0002] At present, the application of laser radar measurement technology in various production scenarios such as work and life is more and more common. At this stage, there are still relatively large constraints on its rapid development. Some practical problems of current lidar equipment are as follows: [0003] 1. The product is expensive, and the equipment application is mainly concentrated in units with strong economic strength; [0004] 2. There are few domestic independent brands of products, and there is a big gap in product application coverage compared with foreign brands; [0005] 3. The product is large in size and heavy in weight, so it can only work conveniently with the help of high-performance platform equipment; [0006] 4. The market positioning of equipmen...
