逆向工程中测量数据点的滤波

A study on measured data filter in reverse engineering

针对用于曲面拟合的逆向工程散乱数据点云,提出一种先加权中值滤波,再小波包分析滤波的新滤波方法。为避免繁琐的编程,充分利用M atlab中的小波包滤波函数,提出VC++与M atlab混合编程编制数值计算程序的方法,并用实际计算结果验证了该方法的可行性。

An effective weighted-median filter and wavelet analysis filtering based on the discrete data dots-clouds of reverse engineering of the curves fitting is introduced. In order to avoid plenty fussy programming and make the most of wavelet packet analysis filtering of Matlab, the idea of hybrid programming between VC ＋＋ and Matlab is put forward, and the result of application proves the viability of the proposed method.
