【摘要】 自由曲线重构问题是CAD/CAM工程中的首要问题,为了获得工件的数学模型,需要通过测量的型值点构造曲线。用神经网络的方法对自由曲线进行重构,并通过与三次B样条插值法构建的曲线相比较,以分析由神经网络法拟合复杂曲线的可行性。更多还原

【Abstract】 Freeform curve reconstruction is a important problem in CAD/CAM systemic engineer. The mathematic model of workpieces can be reconstructed, by using data that get from workpieces to reconstruct the curve. The freeform curve is reconstructed by using a neural network. By comparing with interpolation of B-Spline, feasibility of this method is analysed.更多还原
