THREE-DIMENSIONAL SURFACE PROFILE IMAGING METHOD AND APPARATUS USING SINGLE SPECTRAL LIGHT CONDITION

摘要

A three-dimensional surface profile imaging method and system uses a single spectral light illumination constraint to guarantee consistent RGB values corresponding to a given light spectrum, regardless of the surface reflectance characteristics of the object being imaged. In one embodiment, each light sheet projected onto the object contains only a single wavelength. As a result, the spectral composition of the projected light at any surface point of the object will be independent of the light intensity and the reflectance characteristics of the surface.
