A portable laser radar measurement method and device

Abstract

The invention provides a portable laser radar measurement method and device, comprising the following steps: using a DGPS positioning module to obtain target position parameters, using an optical prism scattering scanning system to obtain target position adjustment variable parameters, using a MEMS attitude sensor to obtain target angle parameters, and collecting prisms Rotate the position and angle parameters, construct the target position parameter equation at time t, form a set of target position parameters measured by i laser radar devices, construct the independently distributed parameter interference, maximize the laser radar target positioning model of the target to be measured, and calculate Maximize the minimum accurate solution of the positioning model of the target to be measured; this application uses a portable laser radar measurement method that avoids a large amount of calculation of the least squares method, and the portable laser radar measurement device using this method can be used in low-light or no-light conditions. The measurement environment can be quickly modeled and displayed, and the measurement structure can be dynamically transmitted to other user 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...
