| 摘 要： | 介绍一套目前已在实验室中开发成功的冷轧带钢表面缺陷在线监测系统,该系统用于在线检测和识别冷轧带钢的表面缺陷.系统采用多个面阵CCD摄像头同步采集带钢表面的图像,并通过并行计算系统对图像进行分析和处理,以得到钢板表面的缺陷情况.系统在软件流程上进行了特殊的设计,以保证实时数据处理功能.经试验,系统对"乳化液斑痕"、"锈痕"、"压入氧化铁皮"、"辊印"、"折印"和"边裂"等6种常见的冷轧带钢表面缺陷类型识别率在90%以上.

| Abstract: | An on-line surface defect inspection system for cold rolled strips is introduced. The system is equipped with CCD matrix cameras to capture images of steel surface simultaneously. A parallel computer system is used for image processing to obtain defect information on steel surface. The system is specialized in software designing for real-time data processing. With samples from industry, the system is tested that six types of surface defects of cold rolled strips can be detected and classified with high rate, including "emulsion marks", "rusts", "scales", "roll imprints", "coil breaks" and "edge cracks" .The recognition rate of the system for these six kinds of defects is more than 90%. |
