Corn seed dynamic image fine selection device and method used for oriented sowing

The invention belongs to the technical field of machine vision, and provides a corn seed dynamic image fine selection device and method used for oriented sowing. By means of the corn seed dynamic image fine selection device, acquisition and detection calculation of dynamic image information of corn seeds can be achieved; by means of detection and analysis of appearance features and the image information of the corn seeds, fine selection of the corn seeds can be achieved through the corn seed dynamic image fine selection device and method; the seeds with black embryos exposed out of the tips, the small and circular seeds, the seeds damaged by insects, the mildewing seeds and the adhesive seeds are blown away, and the precision of fine selection is greatly improved; and meanwhile, the prerequisite is provided for arraying, packaging and oriented sowing of the corn seeds in the later period. Detection calculation is sequentially conducted on the corn seeds through tens of detection indexes, the whole detection p
