The invention discloses a recognition system of spliced currency, and belongs to the technical field of the counterfeit money. The recognition system comprises the following steps: inputting image data through a scanner and a camera, and acquiring a scanning gray image and an adhesive tape RGB image; intercepting a left number area and a right number area from the scanning gray image, and preprocessing the number areas; performing binary morphological analysis and number segmentation on the left number area and the right number area, and then identifying whether the left number and the right number are matched by utilizing a template matching algorithm; and if the left number and the right number are matched, identifying whether the adhesive tape is existent, thereby judging whether the money is the spliced money or not. The template matching algorithm adopts a one-dimensional gray projection template matching algorithm. By adopting the template matching algorithm and the image three-primary color segmentation method, the left number area, the right number rea and the adhesive tape area in a brightness image are extracted, and the relevance principle and a threshold method are usedfor detecting and recognizing the spliced money, the spliced money in 2015 edition can be high-precisely recognized, thereby laying foundation for identifying the spliced money by the automatic cashdeposit machine.
