Outline of Final Research Achievements |
In this research project, we have developed a technique to estimate surface normals using the gadget which can freely change the illumination and the polarization analysis. We have established the fundamental principle for shape measurement of transparent object in this project period, and we have obtained some experimental results which implies that it is possible to measure the shape of transparent objects. In addition to the first plan, we have also developed shape measurement techniques through different approach. We have developed a technique for estimating surface normals of colored objects with specular reflection based on photometric stereo method.
