Problems solved by technology

[0004] Of course, optical recognition is the most direct method, however, optical recognition is also the most difficult
Because most image recognition programs often involve complex algorithms, if this makes the recognition mechanism expensive, it will make it difficult to popularize because of the high cost

Embodiment Construction

[0038] Please refer to FIG. 1( a ), which is a correlation diagram of some components of the optical identification device 10 . The optical identification device 10 is used to identify special-purpose paper 11 , such as banknotes, identification cards, checks or various securities. The optical recognition device 10 has a light source 102 , a spectroscopic device 104 corresponding to the light source 102 , two optical detectors 106 , and an image recognition circuit 108 .

[0039] The light source 102 emits visible or invisible light 120 , and the light 120 is split into two main beams 122 , 124 by the beam splitter 104 . When the paper 11 moves through the inspection zone in a predetermined direction, the two main beams illuminate the area of ​​the paper 11 that passes through the inspection zone and generate responsive images 126, 128, respectively. The two optical detectors 106, such as CCD or CMOS image capture circuit, respectively receive the response images 126, 128, an...

Abstract

The invention is an optical recognizing device for recognizing papers with special use, such as paper money, comprising at least a light source, at least a light splitting device, at least two optical detectors and a picture identification circuit, where the light splitting device splits the light generated by the corresponding light source into two main beams, which are projected on the paper to be detected to form above two response pictures, and the optical detectors receive these response pictures and the picture identification circuit recognizes true or false and kinds of the papers by analyzing these response pictures.

Description

technical field [0001] The invention relates to an optical identification device and method, in particular to an optical device and method for testing special paper. Background technique [0002] Due to the advancement of electronic technology and the increase of labor costs, more and more tasks are performed by automatic machines, such as various vending machines, money changers and so on. Initially, automatic machines mainly used low-denomination coins, and often used volume, density, conductivity and other characteristics to identify the authenticity of coins. However, as there are more and more high-value applications of automatic machines, high-value banknotes will inevitably become objects that automatic machines must handle. [0003] However, whether it is to identify the amount or the authenticity, the difficulty of banknote identification is often higher than that of coins. Therefore, many people propose various methods for identifying the authenticity and denomin...
