Dynamic weighing method for coal and gangue in coal-gangue sorting robots

Gong-kuang zidonghua
Image recognition-based coal-gangue sorting robots have become a research hotspot in the field of coal-gangue separation. To address the issue of low recognition accuracy caused by complex real-world conditions—such as dust adhesion, lighting variation, water stains, and coal slurry coverage—a dynamic weighing method for coal and gangue was proposed ...
