Abstract: The effective and fast image processing techenique is important for surface disfigurement dectecting system based on machine-vision for arc segments ceramic magnet.Because mathematical morphology takes on characteristics of making image data simple and making parallel processing easy,this paper provides a method of detecting surface disfigurement with mathematical morphology for arc segments ceramic magnet.By choosing suitable structrue elements,image data with surface disfigurement are operated with methods of morphology and then the outlines of disfigurement are extracted.The test results indicate that this method is effective,and takes on high precision ratio and fast computing processing.

Key words: arc segments ceramic magnet, disfigurement dectecting, mathematical morphology, image processing
