Abstract
A rapid and convenient method has been developed which uses electro-optical computer-based technology to capture the three-dimensional surface data of an object and to replicate the object from the data. In addition, the data may be used for automated mensuration or inspection. Conceived by Solid Photography, Inc. (SPI) it was developed initially for use in replicating portrait sculptures as well as for use in copying and scaling a variety of objects. The method, which uses patterns of white light projected onto the surface of an object, provides a quick and accurate means of recording the three-dimensional surface information in coded form either on film or by a "real time" TV camera.
