Embodiment 1
[0030] Figure 1a It is a flow chart of a banknote pattern data acquisition method provided by Embodiment 1 of the present invention, Figure 1b It is a schematic diagram of the front fluorescent effect of RMB 100 provided by Embodiment 1 of the present invention; Figure 1c It is a schematic diagram of the fluorescent effect on the reverse side of RMB 100 provided by Embodiment 1 of the present invention; this embodiment can be applied to the situation where different exposure conditions are used to irradiate banknotes to be detected, and this method can be executed by an acquisition device for banknote pattern data. This device can be realized by the mode of software and / or hardware, and generally can be integrated in the ATM, and this method comprises following operations:
[0031] S110. Irradiate the front side of the banknote to be detected with a light source corresponding to the first exposure condition, so that the front side of the banknote to be detected presents a l...
Embodiment 2
[0049] figure 2 It is a flow chart of a method for acquiring banknote pattern data provided in Embodiment 2 of the present invention, as figure 2 As shown, the method includes the following operations:
[0050] S210. Irradiating the banknote to be detected with an ultraviolet light source corresponding to a preset exposure condition, scanning the banknote to be detected by a first sensor, and sequentially collecting data of each scanning line of the banknote to be detected.
[0051] Wherein, the preset exposure condition may be the first exposure condition or the second exposure condition, or other set exposure conditions different from the first exposure condition and the second exposure condition may be adopted, which is not limited in this embodiment of the present invention . The first sensor may be a line sensor, which is used to scan each line of data of the banknote to be detected.
[0052] For example, the banknote identification module in the ATM exposes the fron...
Embodiment 3
[0070] image 3 It is a flow chart of a banknote pattern data acquisition method provided in Embodiment 3 of the present invention, as image 3 As shown, the method includes the following operations:
[0071] S310. Use the transmission channel sensor to collect the point signal corresponding to the banknote to be detected.
[0072] Wherein, the transmission channel sensor can be the point sensor that is distributed in the ATM banknote transmission channel, and the transmission channel sensor comprises at least one group and is positioned at the same level sensor node on the same straight line perpendicular to the path of banknotes, and the transmission channel sensor is located at the same level as the banknotes. The path communicates before the banknote recognition module. In the process of banknotes moving, a series of point signals corresponding to the banknotes passing through the sensor can be collected through the transmission channel sensor as the banknotes move. Opt...
