摘　　要：针对麻灰纱混纺质量的评价问题提出纱线横切面均匀度检测法。利用MATLAB进行分布定位网格法计算,将图像转换为能真实反映纤维分布及数量的网格矩阵。结果表明,分布定位网格法能够快速获取黑纤维分布网格图,科学还原麻灰纱混纺纤维图像的基本特征;有效地完成了对麻灰纱切片图的黑纤维数量测算,其计算的相对偏差值在2.86%~16.67%之间。In order to evaluate the quality of low content duey fiber yam,a detection method to measure the evenness of cross-section of blended yam was proposed. By using the MATLAB softwarethe distributed positioning grid method can transform the image into a grid matrix which can reflect the distribution and quantity of fibers. The results show that the method can rapidly obtain the black fiber distribution mesh, and restore scientifically the ba- sic features of the image. The calculation of the number of black fibers in the slices of low content duey fiber yam is completed effectively, the relative deviation of the calculation is between 2.86% and 16.67%.
