Abstract
An identification method for a valuable file and an identification device thereof. The method includes the following steps: (1) acquiring an original infrared image, type, denomination and orientation data of a current valuable file; (2) obtaining size data and infrared characteristic data of a corresponding standard valuable file; (3) applying an image projection conversion technology, and correcting the original infrared image to form a second infrared image matched with the size of the standard valuable file; (4) obtaining the infrared characteristic data of the current valuable file from the second infrared image and comparing same with that of the standard valuable file to identify whether the current valuable file is true or false; and (5) outputting the identification result. This method and device correct the original infrared image, reducing the quality acquisition requirements thereof, and can collect an image directly using a camera on a simply equipped mobile device, improving identification accuracy.
