摘要
基于线性阵列测径技术,利用线阵CCD激光传感器研究纱线直径测量和毛羽估计方法。提出了纱线直径线轮廓特征信号的递归平均滤波算法和直径像素坐标获取的线性插值方法。设计了非接触式实时测量系统,并制定实验方案。通过仿真实验验证了递归平均滤波算法,分析了不同浮动阈值对直径像素的影响及子片段毛羽与直径的变化。仿真结果证实了纱线直径获取算法的有效性、测量系统的可行性和测量结果的良好再现性,且系统能够精确测量纱线直径和估计毛羽率,实现了数据分析过程自动化与实时化。
Based on linear array technology for measuring diameter,a study is made to utilize the linear CCD laser sensor to measure yarn diameter and estimate hairiness,and an algorithm of filtering process on recursive averaging for line profile signal of yarn diameter and linear interpolation for acquiring the diameter pixel coordinates are proposed.This article also plotted a contactless real-time measuring system and prepared an experiment scheme.The algorithm of recursion average filtering was verified by the experimental simulation,and the influence of different fluctuation threshold values on the diameter pixels was analyzed,along with the variation of sub segments’ hairiness and diameter.The results confirmed the validity of the algorithm for obtaining the yarn diameter,the feasibility of the measurement system,and the good reproducibility of the test results.The system can accurately measure the yarn diameter and estimate hairiness,realizing automatic and real-time data analysis.
