针对高速、高分辨率带钢表面质量在线检测，研究开发了以TDI成像技术为基础的视觉检测系统。系统采用高速TDI CCD器件，配合照度自适应LED光源成像，将采集得到的带钢图像经光纤送至图像分送器，各处理单元并行接收图像分送器的数据并进行实时处理，完成带钢表面质量检测。现场应用表明，基于TDI成像技术的镀锡带钢表面质量在线检测系统可有效实现镀锡带钢表面缺陷检测。

For high-speed, high-resolution images of steel strip surface online inspection, a machine vision system based on TDI (Time Delayed Integration) imaging technology was researched and developed. TDI CCD sensor was used and cooperated with adaptive illumination LED light in this system. The acquired images of steel strip were sent to the image splitter through the fiber and then real-time processed by the Image Processing Units (IPU). Surface defects on tin strip were detected in this system. Application and results show effectiveness for tin strip surface defect inspection of the system (SIS) based on TDI (Time Delayed Integration) imaging technology.
