Abstract
A three dimensional imaging system having a diode laser and collimator along with a video camera and digital circuitry wherein when the light from the laser is collimated and hits the surface of an object with the reflected light images picked up by the video camera and the centroid location of each intersection is interpolated translating two dimensional pixels into three dimension coordinates.
