在工业设计领域中，一般采用的是对粘土模型的测量数据进行采集，然后在CAD中制作三维模型。然而，这种整流罩工作耗时长，需要大量的劳动力，这是一个问题。提出了一种应用于逆向工程技术的自动曲线整流系统。该系统由以下五个步骤构建。(1)关键线数据由三维数字化仪从粘土模型中提取。(2)利用遗传算法对提取的关键线数据进行样条近似。(3)将样条曲线（键线）划分为单调曲率曲线。(4)分析了每条单调曲率曲线的“特性”。(5)在上述分析结果的基础上，将每条单调曲率曲线替换为一种视觉语言，并对每条关键线进行视觉语言重构。通过使用这个系统，我们可以很容易地在短时间内获得设计师想要的美学曲线。
Generally, in the field of industrial design, the measurement data of a clay model are faired, and a 3D model is made in CAD. However, it is a problem that this fairing work takes a long time and requires a great deal of labor. We propose an automatic curve fairing system for the application to reverse engineering technology. The system is constructed by the following five steps. (1) Key-line data are extracted from a clay model by a 3D digitizer. (2) The extracted key-line data are approximated by a spline with a genetic algorithm. (3) The spline curve (key-line) is divided into curves of monotone curvature. (4) The "characteristic" of the curve is analyzed for each monotone-curvature curve. (5) Each monotone-curvature curve is substituted by a visual language based on the result of the analysis mentioned above, and each key-line is reconstructed by the visual language. By using this system, we can easily obtain an aesthetic curve, as intended by a designer, in a short time.
