Abstract: A color sorting method for small-grain agricultural products combining an area scanning photoelectric characteristic and a line scanning photoelectric characteristic is provided. The present invention obtains an area scan image of small-grain agricultural product materials on a conveyor belt by using an area scan camera, which can accurately extract area array features of the materials and realize accurate identification of the unqualified materials. At the same time, the present invention can provide key parameters for accurate positioning during free falling of the materials while identifying the unqualified materials by using the area scan image, and can cooperate with the line scan positioning camera and the pneumatic nozzle to achieve high-speed elimination of the unqualified materials.
