MEHTHOD AND DEVICE FOR MEASURING THREE-DIMENSIONAL SHAPES

摘要

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. In one embodiment, depth detection is possible on a per pixel basis.
