Abstract

A device, method and system for utilizing an optical array generator, confocal measurement/depth of focus techniques to generate dynamic patterns in a camera for projection onto the surface of an object for three-dimensional (3D) measurement. Projected light patterns are used to generate optical features on the surface of an object to be measured and optical 3D measuring methods which operate according to triangulation, confocal and depth of focus principles are used to measure the object.
