Summary: | The invention belongs to the technical field of coal and gangue separation, and particularly relates to a coal and gangue separation method and device based on series connection of visible light and X rays. The coal and gangue separation method comprises the following steps: S1, identifying for the first time; s2, image processing; s3, acquiring a target area; s4, target identification; s5, identifying for the second time; s6, gray features are extracted; s7, obtaining a mapping set; s8, the steps S1-S4 are executed in sequence, so that large gangues are removed; and S7, performing the steps S5-S6 to obtain the gray value of the subsequent coal gangue, and importing the gray value into the mapping set in the step S7 to realize the subsequent separation operation of the coal and the gangue. The problem that simultaneous separation of large and small particle sizes is difficult can be solved, coal and gangue of all particle sizes can be covered, the accurate separation function of coal and gangue of all particl |
