The quality of grain appearance is an important factor in determining price and use. However, the traditional foreign methods rely on the subjective judgment of the human eye on the true appearance of soybeans. And depending on the food quality standard of a department, or a conveyor belt is used but a camera is not used, so that the detection speed can be accelerated, but the food cannot be distinguished by human eyes, and if the camera is not used, the limit of improving the detection speed cannot be broken through. In some parts of America, grains are directly arranged manually and then are directly observed by eyes, and finally, the detection standard of the grain quality is not available even, so that the efficiency is lower, and the method for judging by the eyes has low requirement on objective accuracy, wastes time and labor and has low efficiency.
China is a world-wide agricultural kingdom, and a large number of soybeans are imported and exported every year. The size, roughness and roundness of soybeans are physical indexes for evaluating the quality of soybeans, and actually, the change of the color and luster and the deformation of the appearance of the soybeans can be mostly attributed to insect pests and natural disasters. The quality of soybeans is an important factor in determining their price and use. Firstly, subjective evaluation is formed on grains, and then the industry standard is compared. Although the method is simple, the time consumption is long, the objectivity is lacked, the precision is not high, and the time and the labor are wasted.
In order to improve the efficiency and effectiveness of soybean surface quality evaluation, a soybean image acquisition device is needed to replace human eyes to obtain soybean object images, and the limit of manpower is broken through. Thereby being capable of making good bedding for analyzing soybeans by using image processing and analysis methods more effectively.
