项目摘要

This study carried out for 2 years, and the results are summarized as follows :1. Development of an Autonomous Measurement System of a Physical ModelThe developed autonomous measurement system obtains several shadow images of a clay model, which is roughly and shortly created by a designer or an engineer according to the rough information such as a sketch, by COD cameras. And a rough Z-map model is automatically constructed from the shadow images. Then the position. vectors and the unit normal vectors of points on the targeted clay model are autonomously measured.2. Development of a System for Improving the Quality of Measurement DataN points in the vicinity of a voluntary point selected from among the measurement points are extracted. In order to define a quadratic surface, the least square method is then applied to the measurement data : the position vectors and the unit normal vectors. The position vectors and the unit normal vectors on the selected points are modified as points on the defined quadratic surface. As the result, the quality of he measurement data is improved by applying the process to the all measurement points.3. Development of a System for constructing a beauty shape modelAn aesthetic shape model with curvature continuity is automatically constructed from the improved measurement data. The shape and the high light lines of the shape are indicated to a designer or an operator. When the high light lines are changed by the designer or the operator, a new shape with the modified high light lines are created.

本研究进行了2年的时间，研究结果总结如下：1.物理模型的自主测量系统的开发所开发的自主测量系统通过CCD相机获得粘土模型的多个阴影图像，该粘土模型是由设计师或工程师根据诸如草图的粗略信息粗略地和简短地创建的。并根据阴影图像自动构造了一个粗略的Z-map模型。然后是位置。向量和目标粘土模型上的点的单位法向量的自主测量.用于提高测量数据质量的系统的开发提取从测量点中选择的任意点附近的N个点。为了定义一个二次曲面，最小二乘法应用于测量数据：位置矢量和单位法向矢量。所选点上的位置向量和单位法向量被修改为定义的二次曲面上的点。结果表明，通过对所有测量点进行处理，提高了测量数据的质量.基于改进的测量数据自动构造具有曲率连续性的美学形状模型。将形状和形状的高光线指示给设计者或操作者。当设计者或操作者改变高光线时，创建具有修改的高光线的新形状。
