The invention discloses a material identification method and device and a storage medium, and the method comprises the steps: obtaining an approximate scattering point and a scattering angle corresponding to each particle in a plurality of radiation particles passing through a detection region where a to-be-identified material is deployed; dividing the detection area into a plurality of sub-areas, and for each sub-area in the plurality of sub-areas, selecting radiation particles of which the corresponding approximate scattering points are located in the sub-areas from the plurality of radiation particles, and determining the selected radiation particles as corresponding radiation particles; for each sub-region in the plurality of sub-regions, determining a corresponding scattering density based on the scattering angle of the corresponding radiation particle, and obtaining a plurality of scattering densities in one-to-one correspondence with the plurality of sub-regions; and performing material type identification on the to-be-identified material based on the plurality of scattering densities by using a preset material identification model to obtain a material type identification result of the to-be-identified material. According to the technical scheme, the material identification efficiency is improved.
Description
technical field [0001] The present application relates to the technical field of material detection, in particular to a material identification method, device and storage medium. Background technique [0002] In recent years, problems such as the illegal transfer of nuclear materials and nuclear proliferation are always threatening homeland security, and nuclear material detection technology has gradually attracted the attention of countries all over the world. [0003] Compared with X-ray, the traditional detection method of nuclear materials, muons, as a natural radiation source, have no radiation hazards, are sensitive to high-Z substances, and have strong penetrating ability, so they have natural advantages in the application of nuclear material detection technology. , due to the limited flux of natural muons, in order to improve the image quality of muon imaging, it usually takes a long detection time. poor.
