1.物理模型自主测量系统的研制开发了一套自主测量系统，该系统由设计人员或工程师根据草图等粗略信息，通过COD相机获取粘土模型的多幅阴影图像。并从阴影图像自动构建粗略的Z-map模型。然后是职位。自主测量目标粘土模型上各点的矢量和单位法矢。用于提高测量质量的系统的开发提取从测量点中选择的任意点附近的数据点。为了定义二次曲面，然后对测量数据应用最小二乘法：位置向量和单位法向向量。将选定点上的位置向量和单位法向向量修改为定义的二次曲面上的点。结果表明，通过将该过程应用于所有测量点，提高了测量数据的质量。用于构建美容形状模型的系统的开发从改进的测量数据自动构建具有曲率连续性的美观形状模型。该形状和该形状的高亮线被指示给设计者或操作员。当设计者或操作员改变高亮线时，创建具有修改后的高亮线的新形状。

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.
