A system and method of determining three-dimensional data for an object by performing optical flow analysis to calculate surface profile analysis for a group of monocular component images that vary wavelength distribution, and determining three-dimensional data relating to the object from the component images and the surface profile analysis. Stereo image features are obtained from a single monocular polychromatic raw image or multiple monocular grayscale images having known spectral imaging collection data. Apparatus are described which allow three-dimensional data for an object to be determined from one or more two-dimensional images of the object.
