本文是系列文章的第二部分，报道了一种计算机方法的最新发展，该方法用于从水浴中捕获的纱线样品图像中自动测量和识别纱线湿纱结。在我们前期的工作中，我们开发了一种完全计算机化的纱线结节测量的数字图像信号方法，并对各种影响因素对识别算法的影响进行了数值分析。本文通过实验室实验，对全电脑化方法测量实际纱线湿绞线的可行性和准确性进行了评价。制备了7、10、16和20Ne的100%纯棉环锭纱单纱，并用于评价。除了单位长度的扭结圈数外，还利用计算机方法客观地测量了纱线样品的扭结高度和宽度。对计算机化方法的测量结果进行了分析，并与用扭度仪和交互式计算机方法进行的人工测量结果进行了比较。
This paper is the second part of a series reporting the recent development of a computerized method for the automatic measurement and recognition of yarn wet snarls from an image of snarled yarn samples captured in a water bath. In our earlier work, a digital image-signal approach for fully computerized yarn-snarl measurement was developed and the effects of various influencing factors on the recognition algorithms were numerically examined. In this paper, the feasibility and accuracy of the fully computerized method on the measurement of actual yarn wet snarls are evaluated through laboratory experiments. One hundred percent cotton ring spun single yarns of 7, 10, 16, and 20 Ne are prepared and used for the evaluation. In addition to the number of snarl turns per unit length, the snarl height and width of the yarn samples are also objectively measured by using the computerized method. The measurement results obtained by the computerized method are analyzed and compared with those measured manually by using a twist tester and an interactive computer method.
