the method comprises the following steps: the multichannel sensing element (3) is arranged in a corresponding multichannel sensing element box (9), then the multichannel sensing element box (9) is fixed above a note inlet of a currency detector, the notes are put into the note inlet from the note inlet, and the currency detector drives the notes to carry out note feeding and counting;
step two: in the process of feeding and twisting the paper money, the color numerical value of each paper money can be collected by the photodiode (4) and the LED multicolor light source plate (5) on the multi-channel sensing element (3), firstly, the LED multicolor light source plate (5) is used for irradiating the light source on the front and back surfaces of the paper money, and the light source irradiated on the paper money can be reflected to the photodiode (4);
step three: after the reflected tri-stimulus values are collected, color detection is realized by measuring the three primary colors forming the color of the object, the RGB three primary colors of the paper money to be identified are collected and parameterized, and then the parameterized data of the paper money to be identified and the parameterized data of the paper money classification database are distinguished and analyzed, so that the face value and the authenticity of the paper money to be detected can be obtained.
