工件表面纹理间距提取的一种新方法

A new method of detect the distance of workpiece surface texture

表面质量是机械产品的一个重要指标,如何准确高效地提取衡量工件表面质量的评定参数是当前一个重要的研究方向。研究了一种基于快速傅里叶变换(FFT)方法从工件表面图像提取纹理间距参数,该方法具有精度高,方法简单等优点。

Workpiece surface quality is a significant factor for mechanical production. The research of how to pick-up the parameter which is used for judging the surface quality accurate and effect is very important. This paper introduces a measurement to piCk-up process texture distance parameter by using fast Fourier transform （FFT） ,use this measurement we can obtain the distance parameter more accurate and easy
