Abstract:
1. A method for acquiring a three-dimensional (3D) surface profile data set of an object comprising: with a light source, illuminating a surface of said object with a pattern of light that varies spatially by wavelength such that at least one visible spectrum of light arranged in a rainbow pattern occurs in illumination of said surface; capturing light reflected from said object with a monochromatic camera; sequentially disposing each of a plurality of different color filters on said monochromatic camera such that output from said monochromatic camera is combined into a color image; and calculating 3D data (X, Y, Z) for each visible point on said object based upon triangulation in which each wavelength in said visible spectrum corresponds to an angle with respect to a baseline between said light source and said camera.
