Abstract
Abstract An integrated system generates a model of a three-dimensional object. A scanning laser device scans the three-dimensional object and generates a point cloud. The points of the point cloud each indicate a location of a corresponding point on a surface of the object. A first model is generated, responsive to the point cloud, that generates a first model representing constituent geometric shapes of the object. A data file is generated, responsive to the first model, that can be inputted to a computer-aided design system.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
120 words
A method of manually separating from a plurality of clouds of points, representing a plurality of three-dimensional geometric features consisting of objects and surfaces in a scene, a subset of the points that represents a desired feature in the scene, the method comprising: selecting all the point clouds that include at least some data points representing the desired feature; and changing a view of the clouds to provide a different two dimensional projection of the three dimensional clouds and manually drawing a polygonal lasso around the desired points in the current view to refine a selected subset of points to be included in a point sub-cloud and repeating the refining as many times as required to obtain the desired sub-cloud.
