The invention relates to the technical field of rice detection, discloses a rice mixing rate detection method and device, and aims to solve the problems of low efficiency and poor accuracy of an existing rice mixing rate detection mode. The scheme mainly comprises the following steps: carrying out grain-by-grain image acquisition on a rice sample, and carrying out image preprocessing on each single image; determining a rice type corresponding to each single image by using a pre-trained deep learning model; calculating a pixel area and a minimum enclosing rectangle of a region formed by the rice contour in each single image, determining a rice grain length of the corresponding rice according to the minimum enclosing rectangle and the image acquisition parameters, and determining a rice grain shape according to the rice grain length; and determining the rice quality of the rice corresponding to each single image according to the rice types, the rice grain types and the pixel area, and determining the rice mixin
