摘　　要：双须影像法是一种基于双端随机须丛快速、低成本的测量纤维长度的方法,须丛曲线的测量计算精度是该测量方法的首要保证。为了考查Wu-Wang算法在棉纤维须丛曲线计算中的应用价值,首先考查检测器的线性工作范围、双端影像法所需测量的棉须丛个数,而后利用Wu-Wang算法计算须丛透光信号各点对应的纤维面密度,进而计算获取随机须丛的线密度曲线即须丛曲线,再将线密度曲线与AFIS(advanced fiber information system)测量数据换算的须丛曲线进行比较,考查其准确度。结果显示,采用线密度不大于3.45g/m的棉条制作2个双端随机须丛,所测得的平均须丛曲线与AFIS测量数据换算得到的须丛曲线非常一致,从而证明了Wu-Wang算法获取的棉须丛曲线具有很高的准确度。Double-side cluster image method is a rapid,accurate and low-cost length measurement method for raw cotton based on the novel sample with dual beards.The calculation accuracy of the fibrogram is the primary guarantee of this method.In order to examine the application value of the Wu-Wang algorithm in the calculation of cotton fibrogram,this paper examined the linear working range of the detector and the number of cotton cluster measured by the double-side cluster image method.Then the fiber density of every unit in the image was calculated by the Wu-Wang algorithm from the transmittance for the linear density curve of random clusters,which was called fibrogram.This fibrogram was compared with the relative counts curve converted by the AFIS measurement data to examine the accuracy of the fibrogram.The results show that when the cotton sliver density is less than3.45g/m and the cluster number is two,the average fibrogram shows high accordance with that from the AFIS,that is to say Wu-Wang algorithm exhibits high accuracy in the application of cotton length measurement.
