Coal gangue identification method and device based on millimeter wave imaging and optical image, and storage medium

The invention discloses a coal gangue recognition method based on millimeter wave imaging and an optical image, a computer device and a storage medium, and the coal gangue recognition method comprises the steps: carrying out the millimeter wave imaging of a coal mine, obtaining millimeter wave data, carrying out the three-dimensional reconstruction of the millimeter wave data, obtaining a three-dimensional image, and extracting a two-dimensional image from the three-dimensional image. According to the pixel value distribution in the two-dimensional image, identifying the components of the coal mine, and the like. According to the invention, the coal gangue components and the coal components in the coal mine can be displayed through the amplitudes of the pixel points of the two-dimensional image; due to the fact that efficient and accurate recognition is achieved through electromagnetic scattering characteristics of coal components and coal gangue components, the interference degree of environmental factors su
