A Vegetation Classification and Identification Method

[0032] Such as figure 1 As shown, a vegetation classification and recognition method for hyperspectral image and laser radar point cloud data fusion, the method includes:

[0033] S1: Data preprocessing, including lidar point cloud LiDAR (Light Detection And Ranging) preprocessing and hyperspectral image HSI (HyperSpectral Image) preprocessing;

[0034] S2: Hyperspectral image and lidar point cloud data registration, by establishing a robust feature line / surface registration primitive library, realize the precision registration between heterogeneous lidar point cloud and hyperspectral image, and uniform geocoding to A defined spatial reference system;

[0035] S3: Use the digital surface model DSM (Digital Surface Model) and digital terrain model DTM (Digital Terrain Model) generated by the lidar point cloud to generate a normalized digital surface model nDSM (Normalized Digital Surface Model);

[0036] S4: Use the hyperspectral image to calculate two spectral vegetation ind...
