Abstract:
With the development of information technology, Machine vision technology which has the ad-vantages of accurate, efficient, fast and flexible, receives extensive attention of the public. The application of machine vision technology in industrial production has great potential and effectiveness. Due to the manual measurement of the turnout rail size has problems such as low efficiency and accuracy, subjective and poor consistency, this paper proposes a new mathematical morphological filtering method based on machine vision, called MI-cored which uses a structural element of “M” glyph. Through experiments, by using the MI-cored, the resulting image signal has the smallest noise-signal ratio and the best effect of noise suppression, which is provided to measure the turnout rail size, improves the accuracy of measurement and ensures the quality of turnout rail production.
