software system
Raw data:Binary structured data is a 3D point cloud map consisting of a series of XYZ coordinate information;
Point cloud data processing:Processes such as 3D coordinate transformation, noise point removal, intraday point cloud data synthesis, point cloud ground filtering, wind speed filtering, etc., combined with human judgment filtering (e.g., tower, bracket base, etc., can be manually cropped at once during installation);
Optimization of structural parameter extraction algorithms:Optimal rasterized canopy height extraction model; Estimating the daily change of vegetation volume based on volumetric surface differencing and obtaining vegetation temporal change characteristics.

Application Cases
激光雷达与物候相机组合，观测生长物候的同时，为点云数据计算验证提供参考
数据处理过程
农作物与地面的点云分离–植被覆盖度计算（FVC）–间隙率计算–叶面积指数计算（LAI）。通过一个生长季的数据获取，LiDAR计算得到的叶面积指数与地面实测值时间序列规律非常一致(7天滑动平均）。
