The invention discloses a method and system for identifying water washed banknotes. The method comprises the steps of acquiring an ultraviolet reflection image of a banknote excluding an ultraviolet fluorescent character region; acquiring pixel points with the brightness being greater than a brightness threshold in the ultraviolet reflection image; calculating the area of a connected region of thepixel points; and identifying the banknote to be a water washed banknote if the area of the connected region is greater than the preset area. Under the background of the ultraviolet reflection image,water washed banknote identification is performed on the image region excluding the ultraviolet fluorescent character region by using fluorescence reaction characteristics of the water washed banknote, influences of the ultraviolet fluorescent character region are eliminated, the water washed banknote is accurately identified, and reasonable recycling of the water washed banknote is realized.
Description
technical field [0001] The invention relates to the technical field of banknote identification, in particular to a method and system for identifying water-washed banknotes. Background technique [0002] Washed banknotes are usually banknotes that have been soaked in water and then flattened or washed with a detergent solution. Clean water is generally tap water, and tap water and washing powder generally contain fluorescent bleach. Banknotes that have been soaked in tap water or washed with washing powder solution are different from the original banknotes and cannot be circulated anymore and should be recycled in time. [0003] However, in the prior art, the banknote identification device cannot identify the water-washed banknotes, so that the reasonable recycling of the washed banknotes cannot be realized. Contents of the invention [0004] The invention provides a method and system for identifying water-washed banknotes. The method and system can accurately identify wat...
