Description
Technical field
This utility model multi-functional bank note cognitron belongs to technical field of machine vision.
Background technology
Paper money recognition, including the new and old identification of bank note, truth identification and incomplete identification, this technology, is extensively applied by the Public place such as bank, market.
At present, new and old identification, truth identification and incomplete identification are difficult to organically combine.Cash inspecting machine can only be distinguish true from false, and cannot judge new and old and incomplete；As long as and genuine note will be spued in the case of being stained by ATM.
Utility model content
In order to solve the problems referred to above, the utility model discloses a kind of multi-functional bank note cognitron, this paper money recognition machine can carry out new and old identification, truth identification and incomplete identification simultaneously to bank note.
The purpose of this utility model is achieved in that
A kind of multi-functional bank note cognitron,
Light source, pin hole, collimating mirror, beam expander, attenuator, bank note bare terminal end and photodiode array is set gradually along the light direction of propagation；Light source and pin hole are together to form point source, form directional light through collimating mirror, then become parallel angle pencil of ray through beam expander, the part directive photodiode array that described parallel angle pencil of ray is not blocked by bank note；
Described light source, is also configured with heater；
Between attenuator and bank note bare terminal end, it is additionally provided with Amici prism, on the reflected light path of Amici prism, is additionally provided with image-forming objective lens and imageing sensor；The light beam launched from bank note, after Amici prism reflects, is imaged onto image sensor surface by image-forming objective lens；
Described imageing sensor includes that visible light image sensor and infrared image sensor, described visible light image sensor and infrared image sensor are by two dimension platform carrying.
Beneficial effect:
The first, arrange due to the structure of light source, pin hole, collimating mirror, beam expander, the part directive photodiode array that parallel angle pencil of ray is not blocked by bank note can be realized, therefore can judge that bank note is the most incomplete according to the quantity receiving optical signal diode in photodiode array；
The second, owing to being provided with attenuator and imageing sensor, therefore, it is possible to image processed under different light intensity and identify, the new and old of coin is judged；
3rd, it is also configured with heater due to light source, therefore can give off infrared ray in a heated state, make whole system work at infrared band, and then identify the infrared anti-false mark on coin, judge the true and false of coin.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model multi-functional bank note cognitron.
In figure: 1 light source, 2 pin holes, 3 collimating mirrors, 4 beam expanders, 5 attenuators, 6 bank note bare terminal ends, 7 photodiode arrays, 8 Amici prisms, 9 image-forming objective lens, 10 imageing sensors, 101 visible light image sensors, 102 infrared image sensors, 11 two dimension platforms.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model detailed description of the invention is described in further detail.
The multi-functional bank note cognitron of the present embodiment,
Light source 1, pin hole 2, collimating mirror 3, beam expander 4, attenuator 5, bank note bare terminal end 6 and photodiode array 7 is set gradually along the light direction of propagation；Light source 1 and pin hole 2 are together to form point source, form directional light through collimating mirror 3, then become parallel angle pencil of ray through beam expander 4, the part directive photodiode array 7 that described parallel angle pencil of ray is not blocked by bank note；
Described light source 1, is also configured with heater；
Between attenuator 5 and bank note bare terminal end 6, it is additionally provided with Amici prism 8, on the reflected light path of Amici prism 8, is additionally provided with image-forming objective lens 9 and imageing sensor 10；The light beam launched from bank note, after Amici prism 8 reflects, is imaged onto imageing sensor 10 surface by image-forming objective lens 9；
Described imageing sensor 10 includes that visible light image sensor 101 and infrared image sensor 102, described visible light image sensor 101 and infrared image sensor 102 are carried by two dimension platform 11；The effect of two dimension platform 11 is to change the service band of imageing sensor 10.
