The VTOL drone is suitable for orthographic and oblique images and LiDAR data acquisition for high-precision and large-area aerial mapping projects. The acquired data can be processed to generate different mapping data results, including Digital Orthophoto Map (DOM), Digital Surface Model (DSM), Digital Elevation Model (DEM), Digital Line Graphic (DLG), real-scene 3D model and LiDAR point cloud model. Providing with basic geographic information and spatial data for various industries, and is widely used in terrain mapping, smart city, property rights confirmation and other scenarios.
In a project of geological hazard investigation in western Sichuan, JOUAV partner used CW-25E to carry JolidAR-LR long range LiDAR to focus on screening hidden geological hazard points at high position. With the penetrating ability of LiDAR to vegetation and powerful DEM visualization technology, more than 30 hidden geological hazard points were finally found out.
In a project in Hongge Town, Yanbian County, Panzhihua, JOUAV partner used CW-15 drone to carry a 210MP full-frame oblique camera to do 3D aerial mapping, then perform property and cadastral survey based on acquired high-resolution 3D model. The horizontal mean square error of the model was 3.3cm, and vertical mean square error was 2.6cm, which greatly improved the operation efficiency.
