Embodiment Construction
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0032] refer to Figure 1-3 , a three-dimensional large-scale water restoration technology that supports cross-Tile topological connections, including the following steps;
[0033]Step 1: Determine the elevation of the water area, roughly draw the range of the water area, and form a hypothetical auxiliary water surface with the same elevation as the water surface to be generated but with a larger range. Before performing water area restoration, the user needs to first determine where the water area is to be repaired and the repaired area The elevation of the water area; to determine where the water area is to be repaired, you can draw a polygon describing the approxi...

The invention relates to the technical field of three-dimensional model data restoration, in particular to a three-dimensional large water area restoration technology supporting cross-Tile topologicalconnection. The method comprises the steps of determining the elevation of a water area, calculating the intersection line of an auxiliary water surface and an original three-dimensional model, adjusting the intersection line, completing the classification of the intersection line, generating a vivid water area texture large image, and repairing the geometric and texture of the water surface oneby one by Tile to complete the repairing of the three-dimensional large water area. The three-dimensional large water area restoration technology is simpler to operate, less in interaction, high in automation degree, higher in efficiency, capable of processing a water area with an island in the middle, high in water texture restoration degree, natural in water surface and shore texture transitionand better in effect, and the restored water surface.
Description
technical field [0001] The invention relates to the technical field of three-dimensional model data restoration, in particular to a three-dimensional large-scale water area restoration technology supporting cross-Tile topological connection. Background technique [0002] The geographic information surveying and mapping industry uses aerial triangulation technology to reconstruct a three-dimensional model of the earth through aerial photography of drones. However, when reconstructing the 3D model of the water surface, due to the single tone of the water surface and the phenomenon of reflection, the feature points of the water extracted from the photos are very few, and the final 3D model of the water is incomplete. At present, there is no good algorithm to solve the 3D reconstruction problem of the water surface. Even the industry-leading 3D reconstruction software Smart3D reconstructs the water surface is broken and incomplete; Modelers repair the 3D model of the water surf...
