  • High-speed 3-D surface measurement surface inspection and reverse-CAD system
    Patent number: 5175601
    Abstract: This invention relates to an apparatus and method for 3-D vision sensing or measurement to rapidly collect X-Y-Z surface data to support dimensional measurement, surface inspection and Reverse-CAD functions. The high-speed three-dimensional surface measurement system for use in determining the surface of an object from at least two electronic signals, has at least a first source for illuminating at least a surface area of the object with at least one fringe pattern.
