ABSTRACT:
An apparatus for digitally representing the surface of a three-dimensional object uses a laser beam to establish a laser line-of-sight from the laser source having a predetermined position to a surface point on the three-dimensional object. The laser beam produces a reflected light beam that a reflecting surface or mirror receives along a view line-of-sight from the surface point through an aperture. By way of triangulating a laser line-of-sight, a view line-of-sight, and a base line-of-sight, it is possible to calculate the laser line of sight distance to the three-dimensional object. The laser line of sight distance is then converted into a digital representation of the surface point on the object. By associating numerous of these surface points, it is possible to form a digital representation of the surface of a three-dimensional object. The result is a high resolution and accurate digital representation of the object surface.
