Abstract
System and method for rapid collection of data points and construction of a computer model based on a multi-resolution mesh to describe the surface contours and color of an object. The system collects data by projecting shapes of light against the object and collecting (from a position of triangulation relative to the light projector) images of the light as it reflects from the object. The system and method of the present invention are comprised of a multiple laser stripe generation process to project a number of light shapes against the object, the collection of one or more reflected laser stripes in a single image of an images collector to gather sufficient information to reproduce points on the surface of the object.
