The invention is applicable to the technical field of image processing, and provides a bill serial number recognition method, a recognition device, a terminal and a computer readable storage medium. The recognition method comprises the following steps: acquiring a bill image; extracting a feature region of the bill image; determining the horizontal direction of a serial number area in the featurearea; selecting a first target area comprising a preset number of serial number characters which are continuously arranged at equal intervals from a specified side to the other side along the horizontal direction, whether a second target area exists on the other side of the first target area in the horizontal direction or not is judged, and the second target area is an area which also comprises the serial number characters of the preset number at equal intervals; if the second target area exists on the other side of the first target area in the horizontal direction, judging whether the ticketdragging situation exists currently or not. The method is beneficial to improving the recognition accuracy of the bill serial number.
Description
technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a bill serial number recognition method, a recognition 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 of the bill is the unique identification of the bill. When issuing a new bill, the most important thing that needs to be recorded is the serial number of the bill. However, in practical applications, when issuing bills, a stack of clean and unsoiled new bills will be placed in the ticket box for sequential camera recognition. Under the existing hardware structure, single bills are usually issued sequentially , this will encounter the ...
