Texture automatic generation and restoration method for oblique photography three-dimensional reconstruction

Abstract

The invention discloses an automatic texture generating and repairing method for oblique photography three-dimensional reconstruction. The method comprises the following steps: step 1, carrying out monotonization on data of oblique photography to obtain data of a single building; 2, performing semantic segmentation on the map of the single building to obtain a texture picture of oblique photography of the building; step 3.1, inputting the oblique photography texture picture obtained in the step 2 into a coding network to obtain a hidden code corresponding to the texture picture; step 3.2, inputting the hidden codes obtained in the step 3.1 into a pre-trained generative network to generate a repaired texture picture; and step 4, performing post-processing on the repaired texture picture generated in the step 3.2, and pasting the texture picture back to the building white film obtained by three-dimensional geometric reconstruction to obtain a complete reconstructed building with textures. According to the method, the style, color, illumination and other information in the original building texture can be reserved, and the distortion problems of image blurring, stretching, breaking and the like can be solved.

Description

technical field [0001] The invention belongs to the field of three-dimensional reconstruction of buildings in the field of remote sensing, specifically to the field of texture generation for three-dimensional reconstruction, and in particular to a method for automatic generation and repair of textures for three-dimensional reconstruction of oblique photography. Background technique [0002] With the development of theory and hardware of photogrammetry and computer vision technology, oblique photogrammetry, as the technical development direction of traditional photogrammetry, not only makes up for the defect that aerial photogrammetry cannot obtain the side texture of buildings, but also provides a basis for the use of photogrammetry to image texture. Mapping provides the possibility, and it also provides a new way for rapid and automatic acquisition of true 3D models of large-area urban buildings. [0003] In the traditional 3D reconstruction of oblique photography, the exis...
