Abstract
Methods are described for automatically generating a three-dimensional model of a structure including real façade textures obtained from geo-referenced oblique images. The geographical position of at least one real façade texture is located. Geo-referenced images containing the real façade texture are located. A base image having the real façade texture is selected from the geo-referenced images by analyzing image raster content. The real façade texture of the base image is applied to the three-dimensional model. Systems for generating the three-dimensional model are also described herein.
