The following description and drawings fully show specific embodiments of the present invention, to enable those skilled in the art to put into practice them.Other embodiments can include structure, logic, it is electric, process and other change.Embodiment only represents possible change.Unless explicitly requested, otherwise single component and function are optional, and the order operated can change.The part of some embodiments and feature can be included in or replace part and the feature of other embodiments.The scope of embodiment of the present invention includes the gamut of claims, and all obtainable equivalents of claims.Herein, these embodiments of the present invention individually or can be represented generally with term " invention ", this is just for the sake of convenient, and if in fact disclosing the invention more than one, the scope for being not meant to automatically limit the application is any single invention or inventive concept.
In order to solve the problems, such as that magnetic security line detection accurate reliability is low in the prior art, the embodiment of the present invention provides a kind of bank note magnetic and buries safety line anti-counterfeiting detection apparatus and method entirely, and the true and false of safety line can be accurately determined by double check, is realized simple and convenient.
Bank note magnetic provided in an embodiment of the present invention buries safety line anti-counterfeiting detection equipment entirely, and as depicted in figs. 1 and 2, wherein Fig. 1 is the side view of the equipment to its structure, and Fig. 2 is the top view of the equipment.The equipment includes：
It is arranged on the light source 104 being oppositely arranged below the transmittance tester 103 and Transfer pipe 102 of the top of bank note Transfer pipe 101；Transmittance tester 103, obtain the transmission image under light source irradiation by the bank note of Transfer pipe.
Image processing apparatus 105, extract the shape facility that the magnetic on bank note transmission image buries safety line entirely
Magnetic detection device 106, the magnetic on bank note that detection passes through Transfer pipe bury the magnetic signal of safety line entirely.
Signal processing apparatus 107, is handled magnetic signal, is obtained magnetic and is buried the two-dimensional encoded of safety line entirely.
Genuine/counterfeit discriminating device 108, judge that magnetic buries the shape facility of safety line and whether meets predetermined shape facility entirely, judge whether two-dimensional encoded be to specify two-dimensional encoded, when being judged as YES, judges that bank note is genuine note, otherwise judges that bank note is counterfeit money.
The said equipment, when bank note enters Transfer pipe from back-note feeder, reaches test position, transmittance tester 103 can obtain the transmission image of bank note, and be post-processed by image processing apparatus 105；The magnetic that magnetic detection device 106 is detected on bank note buries safety line entirely, and transfers to signal processing apparatus 107 to handle the magnetic signal of acquisition.
Image processing apparatus 105 in the said equipment, position of the safety line on bank note can be buried entirely according to magnetic, it is determined that from the magnetic security line region on transmission image, the parameter that magnetic buries the shape facility of safety line entirely is extracted from the region determined.Wherein, security thread feature includes the shapes and sizes of safety line, wherein, the size of safety line is characterized by least one of following parameters：Length, width, area.

Based on same inventive concept, the embodiment of the present invention also provides one kind and buries safety line anti-counterfeiting detection equipment entirely using bank note magnetic, realizes the method that bank note magnetic buries safety line anti-counterfeiting detection entirely, its flow is as shown in figure 3, comprise the following steps：
Step S101：The transmission image being arranged under the light source that the acquisition of the transmittance tester above bank note Transfer pipe is oppositely arranged by the bank note of Transfer pipe below Transfer pipe irradiates.
When bank note passes through Transfer pipe, under the irradiation of transmitted light source, transmission image can be detected by transmittance tester, burying safety line entirely due to magnetic is embedded in bank note, therefore can obtain more preferably safe line image using printing opacity detection.
Step S102：Magnetic on image processing apparatus extraction bank note transmission image buries the shape facility of safety line entirely.
The shape facility of safety line, such as rectangle, square, circular etc. are obtained in the step, at least one in the parameters such as length, width, area can also be obtained.
Whether the magnetic in bank note buries the safety line that safety line is an elongated rectangular shape entirely, can be rectangular shape by detecting the shape of safety line, whether its width, length meet predetermined width, length etc. to differentiate the true and false of safety line.
Image acquiring device can select camera, imaging sensor etc..
Step S103：The magnetic on bank note that magnetic detection device detection passes through Transfer pipe buries the magnetic signal of safety line entirely.
Magnetic bury full safety line be bank note issue mechanism in printing of bank note, the wires that are embedded to using safety line magnetic code technology in bank note are magnetic, and metal wire is set a string it is two-dimensional encoded.Magnetic signal can be detected by magnetic detection device.
Wherein magnetic detection device can be magnetic sensor, can also use magnet array or magnetic head arrays etc..
Step S104：Signal processing apparatus is handled magnetic signal, is obtained magnetic and is buried the two-dimensional encoded of safety line entirely.
Above-mentioned steps S101 and step S102 obtains the shape facility of safety line, step S103 and step S104 obtains two, magnetic security line and encodes the two acquisition process, it performs the time in no particular order, can simultaneously obtain, can also first obtain one of them and sequentially obtain another.
Step S105：Whether the shape facility that genuine/counterfeit discriminating device judgement magnetic buries safety line entirely meets predetermined shape facility.
By the shape facility of acquisition, such as the parameter such as the shape of the parameter such as shape, size and the safety line that stores, size is compared, and when identical, the security thread for illustrating to collect is to meet predetermined shape.
If meeting, step S106 is performed；Otherwise step S108 is performed.
Step S106：Genuine/counterfeit discriminating device judge obtain it is two-dimensional encoded whether be specify it is two-dimensional encoded.
By the two-dimensional encoded of the safety line of acquisition and storage the two-dimensional encoded of genuine note contrasted, if comparing result is identical, explanation be specify it is two-dimensional encoded, otherwise illustrate be not specify it is two-dimensional encoded.
If meeting, step S107 is performed；Otherwise step S108 is performed.
Above-mentioned steps S105 and step S106 execution sequences in no particular order, it is good first to judge which can judge simultaneously.
Step S107：Judge that bank note is genuine note.
When meeting, judge that bank note is genuine note.
Step S108：Judge that bank note is counterfeit money.
When any of which item is not met, judge that bank note is counterfeit money.
