In this work, a trial of modeling a manikin face §using SwissRanger SR-3000 is implemented. The §process includes acquiring data, range data §restoration, registration and surface §reconstruction. Several tests are done to evaluate §the camera s performance. Then, the noisy and low-§resolution range images are restored by MRF by §designing intensity information into the prior so §that the restored range measurements obtain the high §contrast property of the intensity information. The §range images are registered by ICP algorithm. To §improve the performance of ICP according to the §data, several variants are introduced. A new surface §reconstruction and super-resolution algorithm called §2.5D MRF is originated to combine multiple §registered surfaces. This high dimensional MRF §merges surfaces by trying to move locally smooth §patches together and keep the original values for §details. The algorithm is proved to be robust to §noise and registration errors. Finally, a face model §combined by 15 registered views via simple averaging §and super-resolution of the face combined by 3 views §via 2.5D MRF are displayed as the result.
