Multi-dimensional image usually requires huge memory and much calculation time for analyzing a shape or a fringe pattern. The method of the extraction of characteristics proposed in this study, however, requires only memory for characteristics that has the information of the object and it reduces memory and calculation time. The results of this study are as follows :(1) Multi-dimensional image processing system was constructed. The theory and the algorithm of the extraction of characteristics of an image were proposed.(2) The program 3D-CAFRAN/FT for the above system was developed on a workstation.(3) The multi-dimensional image memory and the system for the extraction of characteristics were constructed and the automated computer controlled system was developed.(4) Photoelastic fringe patterns and interferometric fringe patterns obtained by holographic interferometry and Twyman-Green interferometry are analyzed. Measurement of flatness with the order of 1nm became possible.(5) Non-contact shape measurement of a steel plate, a human body model, a plastic resin work made by press and a half sphere was performed, and propagation of a crack was analyzed. The shape measurement of the order of 0.01mm became possible.

多维图像通常需要大量的内存和大量的计算时间来分析一个形状或条纹图案。然而，本研究提出的特征提取方法只需要记忆具有目标信息的特征，减少了记忆和计算时间。研究结果如下：(1)构建了多维图像处理系统。提出了图像特征提取的理论和算法。(2)在工作站上编制了上述系统的3D-CAFRAN/FT程序。(3)构建了多维图像存储和特征提取系统，开发了计算机自动控制系统。(4)分析了全息干涉法和Twyman-Green干涉法获得的光弹性条纹图和干涉条纹图。1nm量级的平面度测量成为可能。(5)对钢板、人体模型、压塑树脂制品和半球体进行了非接触形状测量，分析了裂纹的扩展。实现了0.01mm量级的形状测量。
