ABSTRACT:
A 3D vision system utilizes a CCD camera to first generate a two dimensional image of the object. A computer analyzes the two dimensional image to determine areas of interest, such as high contrast areas which indicate sharp discontinuities. A laser range scanner, controlled by the computer, then scans the object at a variable resolution, increasing its resolution in the areas of interest to generate a computer model.
