(1)Extraction of Visual Language and an Automatic Fairing SystemWe analyzed a lot of curves drawn by designers, extracted visual language, and systematized the visual language. We proposed a method for measuring a clay model of a car using a non-contact type 3D measuring equipment, and a method for extracting visual language from the measurement data. We also proposed a method for constructing whole shape using the combination of the elements of the visual language. On the bases of these results, a prototype of a system for creating curves using the visual language was proposed. This system gives curves intended by designer in a short time, and it was clarified that this system was a good tool for reverse engineering.(2)Optimum Segmentation of CurvesWe proposed a method for segmenting a complex curve automatically by considering the segmentation problem as a problem of determining good knots of a spline. In order to treat data with cusps or jump, we improved the method so that we can treat multiple knots. The method was applied for a problem that obtains a curve model from measurement data of a clay model of a car, and a good result was obtained. We also survey many methods of data fitting, and discussed them in a survey paper.(3)Extraction of a Cognitive Geometry and its Application for PrimitivesWe analyzed face structure of primitives and polyhedrons, and we systematized the extracted polyhedrons as a visual language.(4)Measurement of a 3D Object and its 3D modelingWe measured shape and texture of a stuffed specimen of a Japanese wolf preserved at Wakayama University using a non-contact type 3D measuring equipment. Using the data, a 3D digital model of the stuffed specimen was made, and a virtual museum of Japanese wolf was constructed.

(1)视觉语言的提取与自动光顺系统分析了设计师绘制的大量曲线，提取了视觉语言，并将视觉语言系统化。提出了一种利用非接触式三维测量设备测量汽车粘土模型的方法，以及从测量数据中提取视觉语言的方法。我们还提出了一种利用视觉语言的元素组合来构建整体形状的方法。在此基础上，提出了一个基于可视化语言的曲线生成系统原型。该系统能在较短的时间内给出设计者想要的曲线，说明该系统是一个很好的逆向工程工具。(2)曲线的优化分割本文提出了一种复杂曲线的自动分割方法，将分割问题归结为确定样条线的好结点问题。为了处理具有尖点或跳跃的数据，我们对方法进行了改进，使其可以处理多个节点。将该方法应用于从汽车粘土模型的测量数据中获取曲线模型的问题，取得了较好的效果。(3)认知几何的提取及其在基元中的应用我们分析了基元和多面体的人脸结构，并将提取的多面体作为可视化语言进行了系统化。(4)三维物体的测量及其三维建模利用非接触式三维测量设备测量了和歌山大学保存的一只日本狼的填充标本的形状和纹理。利用这些数据，制作了填充标本的3D数字模型，并建立了日本狼的虚拟博物馆。
