Abstract
A method and system for applying photo texture to geolocated 3D models operates within a 3D modeling system. The modeling system includes a modeling application operating on a workstation and a database of geotagged imagery. A 3D model created or edited within the 3D modeling system is geolocated such that every point in the 3D modeling space corresponds to a real world location. For a selected surface, the method and system search the database of imagery to identify in the database one or more images depicting the selected surface of the 3D model. The method and system identify the boundaries of the selected surface within the image by transforming two or more sets of coordinates from the 3D modeling space to a coordinate space corresponding to the image. The portion of the image corresponding to the selected surface is copied and mapped to the selected surface of the 3D model.
