ABSTRACT:
A method and apparatus for determining the surface orientation of objects in a field of view is provided by utilizing optical polarizers and photodetector arrays. Using the disclosed imaging technique, the polarization states of light can be determined over a two-dimensional distribution corresponding to the field of view. The polarization state at each pixel is correlated with the surface orientation of the corresponding object point. This method and apparatus is suitable for the recognition of three-dimensional objects in robot vision.
