The research of a relic excavated from remains has become popular. A laser measurement device is mainly used for measuring shapes of fragments and cannot measure uneven complicated shapes. So the X-ray computed tomography which can make 3D measurement is being used as the measurement device, but the model generation still requires human intervention. We propose a procedure to automatically recover surface models of fragments with complicated shapes from slice images measured by X-ray computed tomography (CT). The surface model of a complicated shape is automatically formed by setting up a surface patch on each grid and interpolating intermediate points between the 2 corresponding contours. So far all the restoration task is done by manual operation as long as we manipulate the relic fragment in virtual space. The precise shape information of a cross section of each fragment can be easily obtained with our method using CT. Therefore, we aim at the automatic restoration using the information
