| 摘 要： | 采用自相关函数对不同加工工艺形成的非平面工件表面粗糙度进行了研究。讨论了自相关函数及其扩展度参数与图像纹理特性的关系，构建了实验装置，利用图像处理软件对实验所得的激光散斑图像进行了处理，得到了自相关函数及其扩展测度参数随表面粗糙度的变化曲线。为研究非平面工件的粗糙度，提供了一种新的方法。

| Abstract: | The non-planar surface roughness formed in different processing is studied based on autocorrelation function. The relationships between autocorrelation function, measuring parameter and image texture are discussed. The experimental setup is built. The laser speckle is processed by image processing software. The relation curves of autocorrelation function and surface roughness are obtained. |
