Image Processing Based on Gray Information in Sorting System of Coal Gangue

摘要

Gangue sorting is an important part of coal production, which is to choose gangues from coal blocks. In China, hand sorting is adopted in the separation of large gangues, and workers have great labor intensity and low production efficiency. The intelligent sorting system of coal gangue can be realized through automatic sorting technology based on machine vision and mechanical arms with independent control. Image processing is the key technology of sorting system. Through the image processing of coal and gangue characterization, it is convenient and quick to solve the problem of identification difficulty, so as to improve the accuracy and efficiency of sorting.
