Method for predicting instantaneous leaf output of wind separator based on steady-state duty ratio in wind separation process

The invention relates to the field of threshing and redrying production and processing, in particular to a method for predicting the instantaneous leaf output quantity of an air separator based on the steady-state duty ratio in the air separation process. The method comprises the following steps: acquiring an internal image of a wind separator based on a machine vision device; the collected image is processed; calculating the tobacco leaf area and the steady-state duty ratio according to the processed image; and then the instantaneous leaf outlet amount of the air separator is calculated through the steady-state duty ratio according to a preset function relation. The air separation process in the air separator can be directly monitored in real time, the leaf outlet quantity index of the air separator can be quickly and nondestructively evaluated by utilizing an image processing method, the material state is helped to be judged, a production line is helped to adjust air separation process parameters in time, t
