Material component determination method and device, terminal and readable storage medium

The invention relates to a material component determination method and device, a terminal and a readable storage medium, and relates to the technical field of rock identification; the method comprises the steps: obtaining a material slice image; inputting the material slice image into a crystalline state identification dichotomy model, and outputting to obtain a single-crystalline-state component set image and a non-single-crystalline-state component set image; receiving scanning data; verifying the single crystalline component identification result based on the scanning data to obtain a verification result; and determining the components of the material sheet based on the single-crystal-state component identification result, the non-single-crystal-state component identification result and the verification result. In the process, only the position corresponding to the single crystal state component set image needs to be scanned, so that the area of a scanning region is reduced, the working time consumed by sc
