The goal of this study involves the development of the new 3D sensing technology and its applications. The new 3D sensing technology is capable of real-time shape acquisition of a high-speed moving/deforming object. Particularly, I focused on the method for the high-resolution shape reconstruction and applications for man-machine interface.I have proposed a method for High-resolution shape reconstruction. This method enables the reconstruction of high-resolution shape by integrating multiple time-sequential range images. Also the estimation method for non-rigid deformation has been developed in this study. This method achieves accurate surface estimation and planar development based on a mathematical model involving the physical features of the developable surface. In addition, based on the high-speed 3D sensing technology, I have developed an interactive display system. The proposed system is a variant of the multi-touch display technology that introduces an original way of manipulating three dimensional data by utilizing the deformable tangible screen. As another application, I have developed a new book digitalization technology of scanning large stacks of paper while the user performs a continuous page flipping action. The developed technology shows that it is possible to recognize the 3D deformation of the flipped papers and reconstruct the original flat image.

本研究的目标涉及新的 3D 传感技术及其应用的开发。新的3D传感技术能够实时获取高速移动/变形物体的形状。特别是，我重点研究了高分辨率形状重建的方法及其在人机界面中的应用。我提出了一种高分辨率形状重建的方法。该方法通过集成多个时序距离图像来重建高分辨率形状。本研究还开发了非刚性变形的估计方法。该方法基于涉及可展开表面物理特征的数学模型，实现了精确的表面估计和平面展开。另外，基于高速3D传感技术，我开发了交互式显示系统。所提出的系统是多点触摸显示技术的一种变体，它引入了利用可变形有形屏幕来操纵三维数据的原始方法。作为另一个应用程序，我开发了一种新的书籍数字化技术，可以在用户执行连续翻页动作时扫描大堆纸张。所开发的技术表明，可以识别翻转纸张的 3D 变形并重建原始平面图像。
