The invention is applicable to the technical field of image processing, and provides a bill detection method, a bill detection device and a terminal. The bill detection method includes: acquiring the color visible light image of the bill, the infrared transmission image of the bill and the ultraviolet transmission image of the bill; based on the color visible light image, locating the character pattern corresponding to the serial number of the bill; determining the character pattern according to the positioning result The first character area on the infrared transmission image, and determine the second character area of the character pattern on the ultraviolet transmission image; determine whether the image corresponding to the first character area meets the first preset condition, and determine the second character area Whether the corresponding image satisfies the second preset condition; if the image corresponding to the first character area satisfies the first preset condition, or the image corresponding to the second character area satisfies the second preset condition, it is determined that the ticket has an abnormal serial number. The invention can effectively detect the abnormal situation that the serial number on the bill is altered.
Description
technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a bill detection method, a bill detection device, a terminal and a computer-readable storage medium. Background technique [0002] At present, bill business such as certificate of deposit, check or bill of exchange is becoming more and more common in people's life, and bill business usually involves a large flow of funds, so the detection and processing of bills is particularly important. [0003] The serial number is a relatively important piece of information in the entire face information of the bill. Bill detectors usually search for the target bill from the bill box based on the serial number of the bill, and compare the information on the face of the bill. In some cases, criminals will use red pens, highlighters, black pens or pencils to alter the serial numbers on the bills. Such as figure 1 As shown, the serial number on the bill can be identified a...
