Architectural pattern detection and modeling in images

摘要

Systems and methods are provided to facilitate architectural modeling. In one aspect, repetitive patterns are automatically detected and analyzed to generate modeled structural images such as building facades. In another aspect, structural symmetry is analyzed to facilitate architectural modeling and enhanced image generation.

1. A method, comprising:
extracting, by a system comprising a processor, a set of initial sample portions of an image, wherein the set of sample portions comprises a set of grid information, a set of image space information and a set of lattice information associated with the image; generating, by the system, a set of similarity maps representing similar image elements between the initial sample portions of the set of initial sample portions, wherein the set of similarity maps is based on at least one similarity measurement; selecting, by the system, a set of repetitive patterns and a set of architectural objects from the set of initial sample portions, wherein the set of repetitive patterns is selected based on the set of similarity maps; clustering, by the system, subsets of repetitive patterns of the set of repetitive patterns and architectural objects into aggregated repetitive pattern groups based on a set of procedural modeling rules, wherein the aggregated repetitive pattern groups represent a shape, an architectural element, or a structure of a synthetic façade model; and matching, by the system, the aggregated repetitive pattern groups to architectural objects of a data store corresponding to a synthetic facade model template.
