[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0049] Such as figure 1 As shown, the method for constructing a CSG model according to the laser radar grid point cloud according to the present invention includes the following steps:
[0050] Step 101, read the grid point cloud data acquired by the ground laser radar, and use the grid point cloud data to construct a spatial index structure tree.
[0051] In the present invention, the data of the leaf nodes of the spatial index structure tree includes the three-dimensional minimum outer box information of the node, the two-dimensional row and column number outer rectangle information, the node name identification information, the identification information of the node storage point coordinates, and the three-dimensional coordinate offset parameter information.
