Abstract(in English) | This study proposes a method to estimate elastic deformation using silhouettes obtained from multiple endoscopic images for endoscopic surgery. Our method allows to estimate local deformation of organs with internal structures using a volumetric mesh model reconstructed from preoperative CT data. A visual hull is computed from silhouettes and used as a constraint on the view volume. The model shape is updated to satisfy the constraint while preserving the shape as much as possible. The result of the experiments showed that the proposed methods could estimate the deformation with 5mm-1cm RMS errors. |
