Research on Automatic Coal Sorting Technology Based on Machine Vision

摘要

Automatic coal sorting technology based on machine vision has the function of analyzing whether there is material on the conveyor. Contour of image will be found when there is material on conveyor. The average of color will be calculated according to respective proportion of blue component and the red component in the contour. Comparing the average with the setting threshold judges the type of material. The technology has advantage of high efficiency, good stability, reliable, etc. The system also has the function of sending signals to sorting equipment and statistic number of various materials. The system reduces production costs in coal companies, and improves production efficiency, enhance the competitiveness of companies.
