Описание:
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...Похожие книги
