Determining Surface Orientations of Transparent Objects
Based on Polarization Degrees in Visible and Infrared Wavelength
Daisuke Miyazaki Megumi Saito Yoichi Sato Katsushi Ikeuchi
We present a new method for obtaining surface orientations of transparent surfaces through analysis of the degree of polarization in surface reflection and emission in visible and far-infrared wavelength, respectively. This parameter, the polarization degree of reflected light at the visible wavelengths, is used for determining the surface orientation at a surface point. The polarization degree at visible wavelengths provides two possible solutions, and the proposed method uses the polarization degree at far-infrared wavelengths to resolve this ambiguity.
