激光雷达原理演示实验装置的设计与研发

Design and development of experiment device for demonstration of LiDAR principle

为将激光雷达的基本工作原理和测量方法引入教学领域,以激光雷达为基础,设计了一套激光雷达原理演示实验设备。通过获取激光飞行时间、能量强弱和发射角度等信息,设计了距离探测、物品形状识别和垂直角分辨率测量等实验。三维调节平台的设计可以使仪器操作简单、读数准确;多场景模拟板可以模拟多种激光雷达工作场景。学生既能直观体会激光雷达的工作原理,又能通过测量数据分析相应性能参数,同时可拓展图像处理技能,提高并丰富了设计性研究性实验教学内容。

In order to introduce the basic working principles and measurement methods of LiDAR into the teaching field,a set of LiDAR principle demonstration experimental equipment was designed based on LiDAR.By obtaining information such as laser flight time,energy intensity,and emission angle,experiments such as distance detection,object shape recognition,and vertical angular resolution measurement are designed.The design of the three-dimensional adjustment platform makes the instrument easy to operate and accurate in reading;the multi-scenario simulation board can simulate a variety of LiDAR working scenarios.It was used not only to understand the working principle of LiDAR directly,but also to analyze the corresponding performance parameters through measurement data,and expand image processing skills,which improved and enriched the experimental teaching content of design research.
