Abstract

A machine vision based soybean seed selection method relates to the field of agricultural automation and aims to solve the problem of low selection accuracy of a traditional soybean selection method. According to the machine vision based soybean seed selection method, normal soybean seeds, mould soybean seeds, gray soybean seeds and soybean seeds with injured kernels are classified, so that the soybean seed selection accuracy is effectively increased by 20%, the soybean seeds are classified without damage, and the appearances of the soybean seeds can not be destroyed. The machine vision based soybean seed selection method is suitable for the field of agricultural automation.

Description

technical field [0001] The invention relates to the field of agricultural automation. Background technique [0002] Soybean is the main economic crop in my country, and the Northeast China is the main soybean producing area in my country. In recent years, driven by the implementation of the soybean revitalization plan by the Ministry of Agriculture, the planting area of ​​soybean in our province has increased sharply year by year. At the same time, the quality standards for soybean selection, export and processing are becoming more and more stringent. At present, the soybean seed selection and selection methods on the market mostly use mechanical principles such as vibration, centrifugation, and friction. However, the equipment designed for this method is bulky, heavy and low in precision, and is generally used for pre-sorting to remove impurities. [0003] The detection of defects, color, saturation and other information on the surface of agricultural products can be used ...
