Embodiment
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, contrast accompanying drawing is illustrated the specific embodiment of the present invention below.Apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, and obtain other embodiment.
For making simplified form, only schematically show part related to the present invention in each figure, they do not represent its practical structures as product.In addition, be convenient to make simplified form understand, there are the parts of identical structure or function in some figure, only schematically depict one of them, or only marked one of them.In this article, " one " not only represents " only this ", also can represent the situation of " more than one ".
Specifically portable equipment of the present invention for carrier with wearable device such as glasses, mobile phone or wrist-watches, is brief description the present invention, is namely described in detail for glasses carrier below.
That shown in Figure 1 is that the portable equipment for paper money recognition of the present invention mainly forms schematic diagram.As shown in Figure 1, the portable equipment for paper money recognition of the present invention comprises image acquisition units 10, coding unit 11, graphics processing unit 12, CPU (central processing unit) 13, detecting unit 14 and voice alerting unit 15, namely describes in detail to those ingredients below.
Image acquisition units 11, for gathering the view data of this bank note when both parties carry out paper money transaction.In the present embodiment, image acquisition units 11 adopts the high definition collection shooting Charge Coupled Device (CCD) image ccd sensor of ten million Pixel-level of such as adjustable focal length, is configured on carrier glasses, gathers banknote image video when carrying out paper money transaction.When carrying out paper money transaction, blind users or counterpart need first the bank note of transaction is taken this glasses anterior locations and by bank note just to glasses, the bank note of now concluding the business just enters the value of feedback high definition collection shooting ccd sensor on glasses, described high definition collection is that photographing module will detect the bank note position entering and gather shooting ccd sensor, described high definition gathers photographing module and the banknote image in video acquisition picture is dodged red boxes mark, and mobile and can automatic focus adjustable with the movement of banknote image.
Coding unit 11 is connected with above-mentioned image acquisition units 10, receives the view data that image acquisition units 10 gathers, and exports after encoding.In the present embodiment, this coding unit is video encoding unit, and the video image for being gathered by above-mentioned ccd sensor carries out Video coding process and forms transmissible media code stream.
Graphics processing unit 12 is connected with coding unit 11, processes the view data that above-mentioned coding unit exports.In the present embodiment, graphics processing unit 12 receives above-mentioned media code stream and carries out compressed video decoder, obtains digital image sequence, and comprises gray processing, illumination compensation pre-service to the original image of input, improves picture quality, obtains gray level image.Send the gray level image finally obtained (the digital picture row namely after gray proces) to CPU (central processing unit) 13 and carry out subsequent treatment.
CPU (central processing unit) 13, graphics processing unit 12 connects, receive above-mentioned gray level image, extract the bank note information wherein comprised, such as extract color and the denomination information of bank note, and extracted bank note information is compared mate with the bank note information (bank note color, denomination) stored in a database (not shown): if the bank note Color pair extracted should be light green color, banknote denomination numerical value is 1, then match with the color of 1 yuan note in database and denomination numerical information, CPU (central processing unit) 13 just judges that this bank note is as 1 yuan; Know bank note Color pair if extract and should be lilac, banknote denomination numerical value is 5, then match with the color of 5 yuan notes in database and denomination numerical information, CPU (central processing unit) 13 just judges that this bank note is as 5 yuan; If the bank note Color pair extracted should be light blue, banknote denomination numerical value is 10, then match with the color of 10 yuan notes in database and denomination numerical information, CPU (central processing unit) 13 just judges that this bank note is as 10 yuan; If the bank note Color pair extracted should be light green, banknote denomination numerical value is 50, then match with the color of 50 yuan notes in database and denomination numerical information, CPU (central processing unit) 13 just judges that this bank note is as 50 yuan; If the bank note Color pair extracted should be light red, banknote denomination numerical value is 100, then match with the color of 100 yuan notes in database and denomination numerical information, CPU (central processing unit) 13 just judges that this bank note is as 100 yuan.After the denomination numerical value judging bank note, the true and false of this bank note need be detected further through detecting unit.
Detecting unit 14, distinguishes the true and false of bank note by fluorescence detection method.The principle of work of fluorescence detection method detects for the papery of bank note.Bank note adopts special paper manufacture (high-quality cotton containing more than 85%), false bank note adopts the common paper after bleaching to manufacture usually, paper after bleaching there will be fluorescence reaction (at ultraviolet excite lower diffraction to go out blue light that wavelength is 420-460nm) under the irradiation of ultraviolet (wavelength is the blue light of 365nm), and true bank note does not then have fluorescence reaction.In this enforcement, detecting unit 14 is made up of ultraviolet source 140 and fluorescence detection unit 141, all be arranged on glasses carrier, during detection, the ultraviolet source 140 be arranged on blind users glasses just carries out irradiating to motion bank note and uses fluorescence detection unit 141 (such as silicon photocell) to detect the fluorescence reflection of bank note simultaneously, judge the true and false (as getting rid of surround lighting to the interference of discrimination in other embodiments of the present invention of this bank note, adopt in other embodiments of the present invention, on the surface of silicon photocell, a set of color filter through wavelength and counterfeit money fluorescence reaction consistent wavelength is installed).
Finally, paper money recognition result (this banknote denomination numerical value and the true and false) is passed to blind users by the form of voice by voice alerting unit.And then blind users can be made to carry out easily concluding the business accurately.
In another embodiment of the present invention, above-mentioned CPU (central processing unit) 13 first detects in received digital image sequence whether to there is banknote image information to be identified, if having, then carries out the bank note Data Matching process of bank note information extraction, the storage of bank note information and date storehouse.
It should be noted that above-described embodiment all can independent assortment as required.The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
