轿车门外板自由曲面的反求

Reverse car outside door plate free-form surface

为了获得已有自由曲面的CAD模型,这里通过对自由曲面的测量、特征提取及曲面构造的方法来定义出自由曲面的几何形状,并用该方法实现了对轿车门板自由曲面的反求,构造出该零件的CAD模型。

To get exist free -form surface CAD model, the geometrical shape of free -form surface is defined by measuring free- form surface, stilling character and constructing surface, and by using this method, the car outside door plate free -form surface had been reversed, the part CAD model had also been constructed.
