摘　　要：本文介绍了一种基于视觉的NC膜划线宽度在线检测的方法。在生物检测试纸的生产过程中,划膜仪对检测线T和质控线C的划线宽度、均匀度决定了其包被的抗原或抗体的数量。所以要严格控制线宽并保证划线的精度以实现定量检测,提高检测灵敏度;还要实现在线检测,否则待C/T线上包被的溶液干透就无法再进行处理。由此,本文设计了一种基于线阵电荷耦合元件(线阵CCD)的在线检测系统,检测精度高,操作方便,可实现划线宽度的实时、在线检测。This paper presents a vision-based method for the width of NC membrane online inspection. In the produc- tion of bio-test strip, the number of antigen or antibody which is coated on the membrane depends on the width and the uniformity of test line T and control line C. People should control the width and the uniformity strictly to ensure the accuracy of lines in order to achieve quantitative inspection with high sensitivity. And online inspection must be done, it cannot be processed when the solution has been dry up. This paper gives a design of online inspection system based on linear charge-coupled device （linear CCD）, it makes such advantages in terms of speed, accuracy, and the operation to achieve real-time, online inspection.
