Abstract: The plate parameter measurement method can be applied to industrial intelligent control. It not only reduces the cost of plate parameter measurement, but also improves the accuracy and efficiency. Based on the practical applicalion and research of object extraction on plate image, the paper proposed a kind of plate parameter measurement method based on ISL(Image Segmentation and Thinning) algorithm that combines image threshold segmentation with image region thinning. Under the premise of ensuring accuracy, the method can effectively eliminate the noise and movement interference and meet the demands of real-time.

Key words: Plate parameter measurement, Image threshold segmentation, Image region thinning
