A Study on Defect Detection of Magnetic Tile Based on the Machine Vision Technology

Magnetic tile plays an important role in permanent magnet motor. Its surface defects seriously affect the performance of the motor. To realize the automatic detection of the magnetic tile surface, the technology of machine vision is adopted and Halcon is selected as the software. In this paper, the research is carried out covering the aspects of classification of the defect, the design of the visual system and the experiment. Through the experiment, the successful rate of detection is high, which provides a theoretical basis for the automatic detection of the magnetic tile.
