摘　　要：利用p-分位数法对三叶形醋酸纤维截面图像进行二值化处理,再利用截面填充的方法实现纤维截面之间的分离,测量三叶形纤维截面形态特征参数。根据三叶形纤维截面边界特点,通过图像的拐点确定纤维截面的外接圆和内切圆,计算出纤维截面的异形度。该测量方法快速、准确、实用,解决了手动测量效率低、精度不稳定等问题。To measure the morphology characteristics of trilobal acetate fiber, the p -quantile method was used to make image binarization and the cross-section filling technique was used to achieve the separation of the fiber cross-section. According to the characteristics of the cross-section boundary, the circumscribed circle and inscribed circle of fiber cross-sectian were determined by searching the inflexion point of the cross-section boundary. Hence the profile degree of the fiber cross-section was obtained. The measurement method was proved to be rapid, accurate and practical, which can solve the defects of the low efficiency and instable accruacy of manual measurement.
