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.
Claims12
An integrated system for generating a three-dimensional model of an object comprising:
- a scanning laser system including;
- a laser for generating a pulsed output;
- a scanning mirror system for angularly scanning the laser pulses over the object and for collecting pulses returning from the object;
- a detector for detecting the returned laser pulses collected by the scanning mirror system;
- a timing circuit for measuring the time of flight of the laser pulses;
- and
- a processor for generating a point cloud corresponding to three dimensional location of points on the object based on the time of flight of the laser pulses and the associated angular orientation of the scanning mirror system, said processor further operating to generate a three-dimensional model from the point cloud, said model including one or more constituent geometric shapes represented by groups of points in the point cloud and for generating a data file that can be inputted into a computer aided design system.
