Integrated system for quickly and accurately imaging and modeling three-dimensional objects
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.
1. A method for merging first and second geometric primitive surfaces, both lying on a single surface, to form a single geometric primitive surface, also lying on the same surface, the first geometric primitive surface resulting from a fit to a first group of points on said single surface, and with the second geometric primitive surface resulting from a fit to a second group of points on the same single surface, said method comprising the steps of:
creating a new group of points by combining the first and second group of points; and
fitting a new single geometric primitive surface using the new group of points whereby different portions of the same surface can be represented as a single surface.
2. A method as recited in claim 1 , wherein groups of points corresponding to two planar surfaces are merged to form a single planar surface.
3. A method as recited in claim 1 , wherein groups of points corresponding to two cylindrical surfaces are merged to form a single cylindrical surface.
