Measurement of Wool Fiber Diameter by Image Analysis

Fiber diameter is the most important raw wool property determining price, processing potential and end use. In this paper, a digital - image- processing algorithm is described for automatically measuring the diameters of wool fibers from microscope images. Experiment result shows that the system is fast, reliable and accurate.     

图像法测定羊毛卷曲度

设计了一个测试系统,研究了采用图像分析技术对羊毛纤维的两维卷曲进行测量的方法,提出了羊毛卷曲的定量指标——卷曲曲率半径,采用切比雪夫曲线拟合的方法构造羊毛卷曲的数学模型,研究了不同测试长度下羊毛卷曲曲率半径的变化,分析了测试长度对测试结果的影响.实测表明,该系统具有较好的可行性.
