Valuable document identification method and device

Abstract

The invention discloses a valuable document identification method comprising the following steps of: (1) acquiring the original red infrared image, the kind, the nominal amount and the orientation data of the current valuable document; (2) the dimension data and the red infrared feature data of a corresponding standard valuable document; (3) carrying out collection treatment on the original red infrared image by applying an image projection transformation technology to form a second red infrared image matched with the standard valuable document in dimension; (4) acquiring the red infrared feature data of the current valuable document from the second red infrared image and comparing the red infrared feature data of the current valuable document with the red infrared feature data of the standard valuable document to identify the authenticity of the current valuable document; and (5) outputting an identification result. Compared with the prior art, the valuable document identification method has the advantages that the original red infrared image is subjected to correction treatment, thus, the requirement for the acquiring quality of the original red infrared image is reduced, a camera on simple mobile equipment can be directly utilized to collect images, and the authentic identification precision is improved. In addition, the invention discloses a corresponding valuable identification device.

Description

technical field [0001] The invention relates to a valuable document identification method and an identification device thereof, in particular to a method and a device for performing infrared image identification of valuable documents on a mobile device with an infrared camera function. Background technique [0002] Although various bank cards are widely used at present, the circulation of cash is still the main way. Some criminals use high-tech technology to imitate and forge valuable documents such as banknotes, which has caused serious harm to society. Sexual demands are getting higher and higher. However, at present, relatively accurate identification equipment mainly includes large-scale machines such as banknote detectors and ATM machines. These equipment are not only expensive, but also not easy to carry, which greatly limits the places where these equipment can be used. Some simple devices, such as highlighters and other devices, are not easy to detect and identify ...

However, at present, relatively accurate identification equipment mainly includes large-scale machines such as banknote detectors and ATM machines. These equipment are not only expensive, but also not easy to carry, which greatly limits the places where these equipment can be used. Some simple devices, such as highlighters and other devices, but although these devices are convenient to carry, it is not easy to detect and identify the authenticity of valuable documents

[0003] The problem faced by the existing technicians is: if the accuracy of the valuable document identification device is to be improved, the accuracy of the collected images of the valuable document identification device must be ensured. For this reason, the valuable document identification device needs to use a stable single light source to Collecting images to improve the clarity and authenticity of the value document image limits the hardware structure and use of the value document identification device, making the structure of the high-precision value document identification device complex and expensive And it is not easy to carry, but the valuable document identification device is faced with the problem of poor identification accuracy due to its simple structure, low cost and easy to carry
