  • Digitizer using intensity gradient to image features of three-dimensional objects
    Patent number: 6639684
    Abstract: A method and apparatus to digitize three-dimensional objects. A projection assembly is retained in fixed relation to an imaging assembly. The projection assembly projects a fixed gradient light pattern into a focal zone of the imaging assembly. The imaging assembly integrates the illumination over time such that the fixed gradient reveals the features of the three dimensional object.
