The invention relates to the bank note identification technical field, and provides a bank note identification method, and identification device, terminal equipment and a computer readable storage medium; the identification method comprises the following steps: obtaining an ultraviolet ray image of the bank note under the ultraviolet ray irradiation; cutting out a local subimage from the ultraviolet ray image; determining a fluorescence double-triangle pattern position in the local subimage according to the local subimage, and obtaining a window image matched with the fluorescence double-triangle pattern; carrying out line projection and/or column projection for the window image, comparing the values after the line projection and/or column projection with preset reference samples, and determining whether a to-be-identified bank note is a normal bank note or an abnormal bank note according to whether the comparison result is consistent or not. The bank note identification method can reduce the interference factors affecting identification accuracy, thus improving the identification efficiency, and improving the bank note identification accuracy.
