Abstract
In the process of positioning and measuring the outer contour of the soft polishing plate,the edges are difficult to ex-tract,and the contour center and radius are low in accuracy.The median filter and grayscale transformation are used to improve the image quality,and the grayscale projection and grayscale variance statistics are used.Edge screening,using the center-constrained least squares method to fit the outer contour,obtain the contour center coordinates and radius through the Gauss-Newton method,and complete high-precision positioning and measurement.Through experimental comparison,the positioning and measurement er-ror of the system is kept within 0.2mm,and the detection speed reaches 0.8s per sheet.It is practical and efficient in production ap-plications,and improves the detection efficiency and production automation of soft abrasive discs.关键词
