摘　　要：为避免传统接触式测量方法导致检测设备与纱线直接接触带来的摩擦损耗,提出了纱线张力非接触式测量方法,设计了基于机器视觉的纱线张力非接触测量系统。使用双目相机检测纱线末端的消耗速度,调控纱线另一端的主动式携纱器的收放速度,使纱线平稳运行,维持纱线张力稳定。研究表明,所设计基于机器视觉的纱线张力非接触式测量系统较常规接触式张力控制方法,控制纱线张力变化幅度降低到25%左右,具有较高的精度和可靠性,能实现三维编织纱线张力的主动控制,具有较强的应用潜力。Since the traditional contact measuring method leads to the direct contact between the testing equipment and yarns and then causes friction loss,a non-contact measuring method is proposed and a noncontact measuring system for yarn tension based on machine vision is designed.Binocular cameras are used to detect the consumption speed of yarn ends.The yarn’s retraction and unwind speed are regulated.And the yarn tension is kept stable.Compared with the conventional tension control methods,the yarn tension change amplitude of the non-contact yarn tension measurement system based on machine vision,is decreased to only 25%of the original.This method has high accuracy and reliability,and can achieve active control of 3D braided yarn tension.It holds strong application potential.
