Corn seed grain directional positioning placement device and method for directional sowing

The invention belongs to the technicalfield of machine vision. According to a corn seed grain directional positioning placement device and a method for directional sowing, through a feeding device and a conveying device, seed grains to be measured are fed periodically and are distributed on a conveyor belt at intervals; through a structural design of a direction-adjusted and faceted placement device, corn seed grains with different embryo surface directions can be respectively placed, and directions of tip ends of the corn seed grains are corrected, so that directional positioning placement is realized. Meanwhile, the external physical characteristics of the corn seed grains are detected and calculated, so that the accuracy of the directions of the tip ends can be greatly improved, conditions are provided for arrangement packaging and directional sowing of the corn seed grains in the later period, and a solution way is provided for realizing mechanically and automatically directional sowing of corns. 本发明属于机器视
