Method and device for measuring impurity-containing specific gravity of grains harvested by combine harvester

Abstract

The invention discloses a method and device for measuring the proportion of impurities contained in harvested grains of a combine harvester, and the method comprises the steps: enabling an industrialcamera, illumination equipment and damping equipment to be installed at a corresponding position, needing to measure the proportion of impurities contained in harvested grains, of the combine harvester, and adjusting the shooting interval and exposure time of the industrial camera; distinguishing grains in the acquired images from other impurities by utilizing a CPU (Central Processing Unit) through an image processing algorithm, and calculating the proportion of impurities contained in the harvested grains; and providing a display device, receiving specific gravity information of impurities contained in the grains through a parallel interface, and displaying the specific gravity information in real time. According to the method and device for measuring the specific gravity of the impurities contained in the grain harvested by the combine harvester, the grain and the impurities can be effectively distinguished, specific gravity information of the impurities contained in the grain is obtained, and the purpose of real-time and accurate monitoring can be achieved.
