纬编针织物疵点的实时检测

 本文构建了图像采集,数据信号处理和光源的纬编针织物疵点实时检测系统.针对纬编针织物部分疵点在图像上灰度分布明显,但形状不规则的特点,使用了细胞神经网络对疵点进行分割;对于灰度差异较小,却呈线形状分布的疵点,引入线检测的方法,使用Radon变换定位疵点的位置.实验表明,该算法可以有效的检测出破洞,漏针,飞花,跳纱,横路和花针等纬编针织物疵点.

Real-time detection of weft knitted fabric defects

In order to detect the weft knitted fabric defects automatically,a real-time system and algorithm for the detection were developed in which the hardware part included image acquisition,signal processing and illumination device,while proograming was performed by Halcon software.The kinds of weft knitted fabric defects were defined as irregular shape and linear shape according to the characteristics of the defects.The cellular neural network was applied for detecting the defects with obvious gray level distri...
