Patent attributes
The invention relates to a method for texturizing virtual three-dimensional objects, particularly virtual three-dimensional building objects and city models with a photographic image (1) of a real object, particularly of a picture of a façade. The method is characterized by the following steps: Projecting the photographic image (1) onto a virtual surface (2) of the virtual three-dimensional object to produce a raw texture; localizing a raw texture element (3) in the raw texture by using a classification method; computer-compatible description of the localized raw texture element by a formal feature set for the raw texture element, particularly a feature vector; comparing the formal feature set of the raw texture element with each feature set of predefined library elements (4), and determining degrees of similarity between the raw texture element and each library element; replacing the localized raw texture element with at least one library element when a predefined degree of similarity is present, and reshaping the raw texture into a generalized texture (5) of the virtual object by replacing all raw texture elements with library elements.
