本文介绍了一种新型的纤维成像系统，该系统可以在纵向上自动采集一系列显微纤维图像，形成长纤维段的全景图像，从而可靠地识别混纺纤维。全景图像显示了长纤维的缩略图，没有丢失或复制样本幻灯片上的任何片段。首先，在X轴和Y轴上快速扫描样品载玻片，以捕获纤维的连续图像并记录每个图像的位置。其次，对子图像的位置进行拼接，形成全景图像。第三，分析全景图像以计算长纤维片段的骨架，该骨架提供纤维形状和位置的简单表示，并为第二次扫描幻灯片配准单个片段的位置。最后，三轴电动工作台将幻灯片传送到每个登记段的位置，重新调整焦距，并捕获高质量的图像用于正式分析。整个捕获过程是完全自动化的，全景视图允许高效的图像捕获，以可靠地识别苎麻和棉混纺纤维。
This paper introduces a new fiber imaging system that can automatically capture a series of microscopic fiber images in the longitudinal view to form a panoramic image of long-fiber segments for reliable identifications of blended fibers. The panoramic image shows thumbnails of long fibers without missing or duplicating any segments on the sample slide. Firstly, the sample slide is scanned quickly in the X- and Y-axes to capture sequential images of fibers and to register the locations of each image. Secondly, a panoramic image is formed by stitching the sub-images together according to their positions. Thirdly, the panoramic image is analyzed to calculate the skeletons of long-fiber segments, which provide simple representations of fiber shapes and locations, and to register the locations of individual segments for the second scan of the slide. Finally, the triaxial motorized stage transports the slide to the location of each registered segment, readjusts the focus, and captures high quality images for the formal analysis. The entire capturing process is fully automated, and the panoramic view permits efficient image capturing for the reliable identification of ramie and cotton mixed fibers.
