实验数据的曲线拟合方法及其应用

曲线拟合技术在图像处理、逆向工程以及测试数据的处理等领域中的应用越来越广泛．目前常见的一些曲线拟合方法中，对各个物理量的处理有失公平性原则，通常是在处理中确保某一个物理量的拟合误差达到“最小”，而没有考虑到其它物理量的拟合误差．本文从这一思路出发，给出了一种新的曲线拟合方法，采用这种曲线拟合方法，对每个物理量的重视程度是相同的．实际的曲线拟合结果表明本文所提出的曲线拟合方法是正确和有效的．

Research and Application of a New Method of Curve Fitting

The technique of curve fitting is used proverbially for the image processing, reverse engineering, test data processing, etc. It is inequitable to process physical parameters by some usual methods of curve fitting. Those methods are performed only by minimizing the fitting error of one physical parameter, but do not take other parameters into account. The new method of curve fitting processes each physical parameter equally The simulation also proves that this new curve fitting method is right and effective.
