摘要
运用计算机的动态显微观察及实时图像处理技术,通过对CCD摄像头、三维载物平台与载物台同步移动的频闪光源、投影光电显微镜、步进电动机等主要硬件的选型与相关软件的开发,研究设计出一种全自动苎麻纤维细度仪。该仪器可快速、准确测定苎麻纤维细度指标直径(d,μm)、公制支数(Nm,m/g)、线密度(ρL,tex)及其纤维不匀率(CV,%)。结果表明,该仪器性能稳定、重现性好、检测误差小、准确度高,单个试样测试时间5 min^6 min,且测定纤维试样根数达1000根/min以上。该仪器的研制成功,填补了我国苎麻纤维细度快速测定技术与设备的空白,为指导苎麻科研与生产中的苎麻纤维准确定等提供可靠支撑。
By using of computer's dynamic microscopic observation and real-time image processing technology,an automatic ramie fiber fineness instrument was designed with selecting and exploiting of relative software of the CCD camera,the 3D loading platform,the strobe light( synchronizedwith the movement of loading platform),the projection optical microscope,the stepping motor,etc. It can rapidly and accurately determine ramie fiber fineness index: the diameter( d,μm),the metric count( Nm,m/g),the linear density( ρL,tex) and fiber irregularity( CV,%). The results showed that the instrument was stable and repeatable as well,small error and high accuracy. A ramie fiber sample was detected for5 min to 6 min and the number of fiber specimens up to 1000/min. The success of developing of the instrument has filled the gap in the field of the quick determination technologies of fiber fineness of ramie in China and provided guidance of ramie fiber products quasi-determination in ramie scientific research and production.
