Application of UAV Airborne LiDAR Technology in Regional 3D Modeling
Airborne LiDAR is an integrated aerial survey platform that integrates global navigation system,DGPS/IMU inertial navigation system and LiDAR system.In order to study and compare the superiority of airborne LiDAR technology and traditional low-altitude photography and measurement technology,innovative technology application means are combined with LiDAR technology and massive LiDAR point cloud data collected by airborne LiDAR field industry are carried out such internal data processing technologies as point cloud solution,point cloud classification and rendering.The elevation information and point cloud texture information were extracted to complete the 3D model construction of the measurement area.Finally,the measurement accuracy was verified according to the industry standard and measurement specification Digital Aerial Photogrammetry.The data results showed that the point cloud accuracy collected by airborne LiDAR could meet the production accuracy requirements.The application of airborne LiDAR technology in UAV will effectively improve the accuracy and efficiency of UAV aerial survey,and meet the needs of more complex aerial survey scenarios.
