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.

本研究历时2年，研究结果总结如下：1。物理模型自主测量系统的开发所开发的自主测量系统，是由设计师或工程师根据草图等粗略信息，通过COD相机，获得粘土模型的几个阴影图像。并根据阴影图像自动构建粗糙的Z-map模型。然后是位置。目标黏土模型上点的向量和单位法向量自动测量。一种提高测量数据质量的系统的开发从测量点中选择一个自愿测量点附近的几个点。为了定义二次曲面，然后将最小二乘法应用于测量数据：位置向量和单位法向量。所选点上的位置向量和单位法向量被修改为所定义的二次曲面上的点。结果表明，将该过程应用于所有测量点，提高了测量数据的质量。基于改进后的测量数据，自动构建具有曲率连续性的美学形状模型。形状和形状的高光线指示给设计师或操作员。当设计师或操作人员改变高光线时，就会创建一个带有修改过的高光线的新形状。
