GENERATING THREE-DIMENSIONAL MODELS FROM IMAGES
First Claim
Patent Images
1. A method that facilitates image-based modeling, comprising:
- receiving input image data representing a faç
ade;
reconstructing input image data with a computing device to compute three-dimensional (3D) points, lines, and camera positions associated with the faç
ade; and
performing a multi-view semantic segmentation on reconstructed input image data to recognize faç
ade structure and segment the faç
ade.

Abstract
The subject disclosure relates to generating models from images. In an aspect, multi-view semantic segmentation is provided to recognize and segment images at the pixel level into semantically meaningful areas, and which can provide labels with a specific object class. In further aspects, a partition scheme is provided that can separate objects into independent blocks using major line structures of a scene. In addition, an inverse patch-based orthographic composition and structure analysis on a block is provided that can regularize noisy and missing reconstructed 3D data to facilitate image-based modeling.
