Title:
METHOD AND APPARATUS FOR PERFORMING THREE-DIMENSIONAL COMPUTER MODELING
Document Type and Number:
WIPO Patent Application WO2006121457
Kind Code:
A3
Abstract:
A method and apparatus for automatically generating a three-dimensional computer model from a "point cloud" of a scene produced by a laser radar (LIDAR) system (114 in Figure 9). Given a point cloud of an indoor or outdoor scene, the method extracts certain structures from the imaged scene, i.e., ceiling, floor, furniture, rooftops, ground, and the like, and models (904) these structures with planes and/or prismatic structures to achieve a three-dimensional computer model (902) of the scene. The method may then add photographic and/or synthetic texturing to the model to achieve a realistic model.
