Method for measuring instantaneous leaf outlet quantity of air separator according to dynamic large leaf area ratio in air separator

The invention relates to the field of threshing and redrying production and processing, in particular to a method for measuring the instantaneous leaf output quantity of an air separator according to the dynamic large leaf area ratio in the air separator. Comprising the following steps: acquiring a real-time image with blades in a wind separation state in a wind separator through a machine vision imaging system; the real-time image is processed; according to a preset pixel area division standard of a large piece, a middle piece, a small piece and a fragment, obtaining an area ratio of a dynamic large piece in the wind separator on the processed image; and measuring the instantaneous leaf outlet quantity of the air separator according to a preset function relation. According to the method, the dynamic proportion of the blade structure, namely the large blade, is measured in real time through machine vision and an algorithm, the method for measuring and calculating the leaf outlet amount of the wind separator i
