无人机激光雷达测量关键参数设置研究
Research on Key Parameter Setting of UAV LiDAR Measurements
摘要
Abstract
In order to improve the data quality of unmanned aerial vehicle(UAV)piggyback light detection and ranging(LiDAR),a comparative experiment is designed using a long-range,high-precision LiDAR system.By adopting different flight altitudes,laser pulse frequencies,and side overlap rates,combining with the analysis of the point cloud density and elevation accuracy,the impacts of these 3 parameters on the quality of the data is investigated.The results indicate that flight altitude is negatively correlated with point cloud density,but has no significant effect on elevation accuracy;increasing the laser pulse frequency will raise the density of point cloud,however,a high frequency can cause energy attenuation and ranging ambiguity;a higher side overlap rate will increase the density of point cloud and ensure the data completeness,but has no significant effect on elevation accuracy.Based on the experimental results,the quantitative parameter settings for UAV LiDAR in scenarios with different vegetation coverage and different terrain types are proposed.关键词
