[0003] The inspection of imperfect grains is a crucial step in grain quality and safety control, directly impacting grain procurement pricing, storage safety, and processing quality. Currently, the application of machine vision technology has brought revolutionary changes to grain imperfect grain inspection, with several companies launching automated inspection equipment based on this technology.
