【摘要】 提出用于表面粗糙度自动干涉法测量过程中的一种有效的白光干涉图像阈值分割方法．分割后的二值图像经过干涉条纹边界线革取后得到的被测表面轮廓波形和表面粗糙度参数的计算结果与高精度ＴＡＬＹＳＵＲＦ６型表面粗糙度测量仪的测量结果十分吻合．此种图像分割方法同样也适用于粗糙表面激光干涉图像的二值化分割．更多还原

【Abstract】 n this paper, a brief and effective method-arithmetic mean thresholding is suggested for segmenting interference image of complex light interfereometer used in automatic measurement of surface roughness. The roughness profile information extracted from binary image after thresholding and calculated results of by sampling enough height deviation data from roughness profile coinside with those charted and measured by TALYSURF 6 profilemeter. This thresholding method are also suitable for segmenting interference image of laser surface roughness interferometer.更多还原
