Embodiment Construction

[0032] Systems and methods are provided for detecting repeating patterns from images and assisting computer three-dimensional modeling. In one aspect, an inspection system and method for detecting repeating patterns in an orthographic texture image is provided. In a given input file, the method can efficiently detect repeating patterns of essentially any shape without resorting to any prior knowledge about the pattern, such as location, size, and shape features. The method and system improve the performance of existing three-dimensional city modeling systems by making building facade analysis more robust and more efficient than previous systems and methods. The system and method are fully automatic methods, which have been applied to many large-scale urban modeling scenarios and achieved good results.

[0033] In another aspect, a method for automatically generating a three-dimensional building front wall model from an image is also provided. The front wall symmetry detection ...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 282,370, entitled DETECTION METHOD OF REPETITIVE PATTERNS IN IMAGES, filed January 29, 2010, the contents of which are hereby incorporated by reference in their entirety. This application also claims priority to US Provisional Patent Application No. 61 / 344,093, entitled METHOD OF FACADE SYMMETRY DETECTION AND MODELING IN IMAGES, filed May 21, 2010, the contents of which are also incorporated herein by reference in their entirety. technical field [0003] The present subject disclosure relates generally to computer modeling methods, and more particularly to the application of detecting and modeling repeating patterns and structural symmetries to more accurately visualize building structures. Background technique [0004] There is an increasing demand for photorealistic building and urban modeling. Among them, three-dimensional ("3D") map servi...
