Method and device for generating three-dimensional data LOD simplified model

The invention relates to a method and device for generating a three-dimensional data LOD simplified model and computer equipment. The method for generating the three-dimensional data LOD simplified model comprises: acquiring oblique photography data to generate an oblique photography model; unfolding the oblique photography model to a two-dimensional plane to obtain a first plane model, and obtaining a texture image on the first plane model; performing geometric simplification on the first plane model to obtain a second plane model; obtaining vertex texture coordinates in a second plane modelaccording to the texture image; and recovering the second plane model into a three-dimensional grid data model according to the vertex texture coordinates. According to the invention, loss of a largenumber of texture details due to direct texture mapping of the three-dimensional oblique photography model in a traditional simplified model is avoided; problem that the texture is distorted due to the change of the geometric
