【 摘 要 】

In this study, a new method of online inspection of contour defects is proposed for stainless steel precision blanking sheet to address problems in the use of the current method to obtain detect information: The recognition system is complex, and the measurement error of defect dimension is large. The images of defect blanking sheet are obtained by the established image collection system. The results of image analysis show that the defect contour of blanking sheet has the correspondence and similarity characteristics. An improved sequential similarity detection algorithm and the measurement algorithm are developed. The measurement experiments show that the online inspection system is stable and reliable, and the maximum measurement error is 0.0362mm. The results of this study will lay a foundation for the online inspection of precision machining.
