GENERATING 3D BUILDING MODELS WITH GROUND LEVEL AND ORTHOGONAL IMAGES

摘要

A system and method is provided for generating textured 3D building models from ground-level and orthogonal imagery. Ground-level images for the sides of building objects are collected to form a 3D dense point cloud for identification of key architectural features, corresponding key façade geometry planes, and generation of a 3D building façade geometry. Orthogonal images are correlated to the 3D building model providing a properly geo-positioned, scaled and textured 3D building model.

1. A method of generating a textured building model, the method comprising:
collecting a plurality of captured ground-level images for at least a first side of a building object; creating a point cloud from the collected plurality of ground-level images; outlining a plurality of vertices for defining edges of at least a single planar surface; selecting a plurality of data points from the created point cloud that represent the single planar surface within the created point cloud; creating simplified façade geometry for the first side; and texturing the simplified façade geometry with at least one of the collected plurality of captured ground-level images.
