激光雷达原理演示实验装置的设计与拓展

Demonstration design and extension based on principles of LiDAR

针对激光雷达在实验教学领域应用较少、相关实验教学方案有待完善的问题,研制了以激光雷达、红外相机、多场景模拟板及三维调节平台为核心部件的激光雷达原理演示实验装置.围绕装置设计了激光测距实验、物体形状识别实验和材料反射率测量实验3个功能性实验,分析采集获取的数据以评价激光雷达的性能.通过运动目标物轨迹追踪实验和利用点云图实现人体三维建模实验2个拓展性实验,让学生了解激光雷达的具体应用,加深学生对该仪器的认识.

As light detection and ranging(LiDAR)was rarely used in experimental teaching,using the main components include LiDAR,infrared camera,multi-scene simulation plate and three-dimensional adjustment platform,a demonstration experimental device based on LiDAR was developed to improve experimental teaching.Three functional experiments,i.e.the laser distance measurement,different object shape recognition and different material reflectivity measurement,were designed.The collected data was analyzed to evaluate the performance of LiDAR.Two extended experiments that moving object tracking experiment and human body 3D modeling experiment using point cloud image were designed to help students to understand the specific application of LiDAR and deepen their understanding.
