Design of 3D Lidar Imaging System Based on Laser Ranging

为了通过激光测距获取目标的三维图像,本文研究了三维激光雷达的基本工作原理、器件选型与集成测试,并讨论了不同测试条件对测试结果的影响。通过激光扫描识别整个测试区域中的目标,然后再根据激光光源到目标的距离信息实现目标三维结构的复现与重建。讨论与分析了该系统所需要的器件类型与参数,最终确定了系统中各模块的型号参数与特性。实验测试了不同位置的光强,结果显示,不同强度及位置对应的激光能量可以用于表示目标的三维位置坐标,验证了系统的可行性。

This study aims to investigate the basic working principle,device selection,and integration test of three-dimensional laser radar in order to obtain a three-dimensional image of the target by laser ranging.The influence of different test conditions on the test results is also examined based on the experimental outcomes.The laser scanning is used to identify the target in the entire test area,and the distance information from the laser source to the target is used to reproduce and reconstruct the three-dimensional structure of the target.This study also analyzes the device types and parameters required by the system and determines the model parameters and characteristics of each module in the system.The experimental results demonstrate that the three-dimensional position coordinates of the target can be represented by the laser energy corresponding to different intensities and positions,the feasibility of the system is verified by the experimental findings.
