Embodiment Construction

[0052] In order to make the purpose, technical solution and technical effect of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0053] It should be noted that all the "left", "right", "upper" and "lower" mentioned in the text refer to the angle of view from the front facing the drawings of the description. In addition, all the "blank areas" mentioned in this article refer to the rectangular area with the largest continuous area where no original characters or patterns can be seen with the naked eye without the aid of a machine. Words or designs on unused or treated banknotes. It should be noted that the blank area is determined as an inherent area of ​​the banknote, even i...

Abstract

The invention provides a paper currency face and orientation identification method and apparatus. The paper currency face and orientation identification method includes the steps: acquiring a target image; extracting the characteristic information of the target image, wherein the characteristic information includes the blank area characteristic parameter, the serial number characteristic parameterand the denomination characteristic parameter; according to at least one of the blank area characteristic parameter, the serial number characteristic parameter and the denomination characteristic parameter, determining the currency type of the paper currency corresponding to the target image, and generating the face and orientation identification result corresponding to the paper currency; and outputting the face and orientation identification result. The paper currency face and orientation identification method and apparatus can reduce the calculation amount during the paper currency face and orientation identification process, can improve the tolerable error rate, and can significantly reduce the output abnormality rate.

Description

technical field [0001] The invention belongs to the field of banknote identification, and more specifically, the invention relates to a Cuban banknote face-to-face identification method and device. Background technique [0002] In the existing technical field of banknote orientation recognition, banknote information is usually obtained by means of image acquisition, and then based on the image and the pre-stored banknote image information (including the front side, front side reverse, reverse front side, reverse side, etc.) Reverse) to match, and then obtain the banknote face (front or back) orientation (forward or reverse) information. However, image matching technology usually needs to match the correspondence between image content, texture, grayscale and so on. First of all, the amount of data involved in the image matching process is large, and the matching cost is high; secondly, the common information of all banknote states will be collected (these common information ...
