Abstract

The embodiment of the invention provides a method and device for generating a building model on a three-dimensional map and a storage medium. The method comprises the following steps: binding size information of a building on UV coordinates; according to the size information of the target building, performing scaling processing on each side grid surface of the target grid chart on the three-dimensional canvas to obtain each scaled side grid surface, wherein the target grid model is a grid model of the target building on the three-dimensional canvas; and determining color information of each side grid surface, and coloring each scaled side grid surface according to the color information and the UV coordinates to obtain a building model corresponding to the target building. According to the invention, the model on the three-dimensional canvas is zoomed according to the size information of the building in reality stored in the UV coordinate, the zoomed grid surfaces are colored according to the UV coordinate, and the building model corresponding to the target building is obtained through rendering. Therefore, the planning effect of distinguishing the form and color of the building on the three-dimensional map is achieved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional mapping, in particular to a method, device and storage medium for generating buildings on a three-dimensional map. Background technique [0002] The building model in the 3D map is usually composed of multiple grids. Each side is composed of multiple grids. For this reason, it is necessary to color each grid surface to generate a more complete and beautiful building. Model. [0003] Usually, the building model in the 3D map is beautified by UV texture mapping according to user needs. In this way, only considering the surface beautification of the building appearance, it cannot realize the planning of the number, location layout and morphological distinction of the buildings on the three-dimensional map, and thus cannot meet all the needs of users. SUMMARY OF THE INVENTION [0004] In view of the problems existing in the prior art, the embodiments of the present invention provide a me...
