摘要
为客观分析上浆纱线横截面切片图像,减少主观因素对分析结果的影响,通过对浆纱横截面切片图像灰度直方图的特征分析,提出了应用高斯(Gaussian)拟合分析灰度直方图的方法。通过对实例中高斯拟合结果主项、次项及其他项构成因素的分析,得出浆料因素在灰度直方图上的分布区间;根据该区间不同灰度概率的正态分布特征,应用3δ原则合理估计了浆料扩散范围,计算出浆纱的几何上浆率和浆料相对分布半径,所得结果与实际相符。
In order to analyze the cross-sectional slice images of sized warp objectively and reduce subjective factors on the results,this paper presents an approach to analyze the gray-scale histogram of cross section slice image of sized warp by Gaussian fitting.We get the distribution of interval of sizing factors in histogram based on the components analysis about main item,sub-items and other items of the Gaussian fitting results.The spread of slurry,sizing percentage and relative radius of pulpiness distribution were calculated with 3δ principle and the normal characteristics of gray in the interval.The experimental results agree with practical values.
