无人机载激光雷达在房地一体测绘中的应用

Application of UAV Onboard LiDAR in Integrated Surveying and Mapping

主要探讨了如何利用大黄蜂四旋翼无人机搭载AS-900HL多平台激光雷达系统完成外业点云数据获取,通过点云解算软件生成高精度点云三维模型,采用CoMapping点云测图软件进行内业测图,形成测图成果后,通过图纸回放外业,进行修补测及间距勘丈的技术方法。通过点位精度和间距精度的验证,充分证明了采用无人机载激光雷达,不但可以达到房地一体测绘的精度要求,而且能够大大提高房地一体测绘的工作效率。

It was mainly discussed the workflow of repairing survey and spacing survey with the Dahuangfeng four-rotor UAV equipped with AS-900HL multi-platform LiDAR system.The field point cloud data were acquired to generate high-precision point cloud 3D model through point cloud solution software,and were applied for mapping with CoMapping.With the surveying results,the field was reconstructed through the drawings,and was used for repairing survey and spacing survey.The verification of point accuracy and spacing accuracy fully proved that the use of UAV onboard LiDAR could not only meet the accuracy requirements of indoor house-field surveying and mapping,but also greatly improved the work efficiency.
