Example Embodiment
[0053] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.
[0054] like figure 1 As shown, the method for land cover classification of airborne multispectral LiDAR data based on super voxels in this embodiment is as follows.
[0055] Step 1: Read the independent point cloud data sets of each band of the original airborne multispectral LiDAR data, and obtain the original airborne multispectral LiDAR multiband independent point cloud data sets;
[0056] In this embodiment, the cropped area of the measured point cloud collected by the Titian airborne multispectral LiDAR system of Optech Corporation of Canada is used as experimental data to verify the effectiveness and feasibility of the method proposed in the present invention. The test area is a typic...
