There is a strong demand for a method of acquiring a non-rigid shape under deformation with high accuracy and high resolution. However, this is difficult to achieve because of performance limitations in measurement hardware. In this paper, we propose a model based method for estimating non-rigid deformation of a developable surface. The model is based on geometric characteristics of the surface, which are important in various applications. This method improves the accuracy of surface estimation and planar development from a low-resolution point cloud. Experiments using curved documents showed the effectiveness of the proposed method.
