Embodiment 2
[0077] Such as figure 2 As shown, the banknote processing method provided by Embodiment 2 of the present invention is based on the technical solution provided by Embodiment 1, and for step S102 "according to the preset determination rules, determine whether the serial number area of the banknote to be processed is Severely defaced" further optimization. Explanations of terms that are the same as or corresponding to the above embodiments are not repeated here. which is:
[0078] Perform binary processing on the serial number area of the banknote to be processed;
[0079] Projecting the area of the serial number along the row direction and the column direction respectively, to obtain the precise area of the serial number in the row direction and the column direction;
[0080] Count the defacement characteristics of the serial number in the precise area;
[0081] According to the defacement feature and the preset threshold range, it is determined whether there is ser...
Embodiment 3
[0101] Such as image 3 As shown, the banknote processing method provided by the third embodiment of the present invention is based on the technical solution provided by the second embodiment, step S204 "counting the defacement characteristics of the serial number in the precise area" and step S205 " Further optimization of determining whether there is serious contamination in the serial number area of the banknote to be processed according to the contamination feature and the preset threshold range. Wherein, the defacement feature includes a gray value and a number of projection passes, and explanations of terms that are the same as or corresponding to those in the foregoing embodiments will not be repeated here. which is:
[0102] S301. Receive banknotes to be processed from the banknote receiving port.
