| titleOfInvention | Water area leveling processing method and computer equipment for manufacturing digital elevation model |
| abstract | The application relates to a water area leveling processing method and device, computer equipment and a storage medium during manufacturing of a digital elevation model. The method comprises the following steps: acquiring laser point clouds and an orthoimage, and classifying the laser point clouds according to the earth surface and the water body to obtain classified earth surface laser point clouds; constructing an irregular triangulation network batch output first digital elevation model based on the surface laser point cloud, and converting the first digital elevation model into a first elevation grid point cloud; constructing an irregular triangular net batch output digital surface model based on the classified laser point cloud, and processing the digital surface model to obtain a water body thematic polygon; and processing the classified laser point cloud, the water body thematic polygon and the first elevation grid point cloud to obtain a second digital elevation model which is output in batches. By adopting the method, the efficiency of producing the DEM based on the airborne laser point cloud can be greatly improved on the premise of ensuring the quality of producing the DEM based on the airborne laser point cloud. |
