英文摘要：

A machine vision based oil seal defect detection on-line system was developed to improve the detection precision and efficiency. The developed system was composed of mechanical transmission system（ conveyor belt,station switching arm,rotating detection workbench and rotating wheel）,electric control system,image acquisition device and oil seal defect detection software system. The experimental results show that,the system can detect the oil seal defects with detection rate of 98%. It also shows the advantages of good real-time performance,high efficiency,good production generality and so on.
