This study investigated sorting points and sorting grades to facilitate the development of a green soybean-sorting machine using image processing. For green soybeans harvested at the optimal time, 36-44% of the pods were classified outside the grade. Of those, 6-15% showed mechanical damage. We classified the mechanical damage into types I-V. Furthermore, we classified the sorting points for shape damage, damage due to green soybean seed maturity, damage due to pests, and mechanical damage. Among those points, pest damage and mechanical damage (type I, type II, type V) that produced color change points in the pods were classified according to the ratio of damaged areas to total pod area. Therefore, grade A was less than 10%, grade B was 10-15%, and outside grade (substandard) was greater than 15%.
