提出了一种利用纱线图像处理得到的纱线直径数据建立数字化纱线黑板的新方法。建立了由摄像机、单片机和步进电机组成的图像采集与处理系统,采集运动纱线的序列图像,经图像阈值和形态学开运算后提取纱线直径数据。然后,纱线的直径数据被用于通过在黑色平面上以白色重绘所有扫描而构建DYBB,一旦它们在中心处对齐。DYBB具有局部数据放大、快速聚焦、相位调整、空间调整等功能,可更直观、方便地评价纱线条干均匀度。
This paper presents a new method for building a digital yarn black board (DYBB) with the yarn diameter data obtained from processing sequential yarn images. An image acquisition and processing system, mainly consisting of a video camera, a single-chip micro-computer and a stepper motor, was set up to capture sequence images of a moving yarn and extract yarn diameter data after the image threshold and morphological opening operation. Then, the diameter data of the yarn was used to construct the DYBB by redrawing all the scans in white on a black plane once they were aligned at the centers. The DYBB provides functions, such as local data amplification, fast focusing, phase adjustment and space adjustment, for more intuitive and convenient evaluation of yarn evenness.
