Corn-seed image carefully-choosing apparatus and usage method for apparatus

The invention relates to the technical field of visual inspection by using a machine, and concretely relates to an corn-seed image carefully-choosing apparatus and a usage method for the apparatus. The technical scheme is characterized in that the a practical efficient on-line carefully-choosing image detection algorithm for corn seeds is provided; a corn-seed turning-over mechanism is designed, which is capable of performing image detection determination on the front side and the reverse side of a corn seed and helps to guarantee accuracy of a detection result; an electromechanical sorting execution mechanism with simple structure is designed; and a novel double-row feeding mechanism is designed, which is capable of continuously uniformly performing double-row feeding on corn seeds. The corn-seed image carefully-choosing apparatus is simple in structure, precise and efficient, and is significant in guaranteeing enforcement of orientated precise sowing of corn, realizing careful choosing of corn seeds before sowing, promoting high quality, high yield and stable development of corn industry in our country and mechanization, automation and intelligentization level of agricultural-product detection.
