Description
Technical field
The present invention relates to the anti-counterfeiting technologies of coin or souvenir badge, more particularly, to a kind of micro- on coin or souvenir badge
Structural anti false recognition methods.
Background technique
Coin anti-counterfeiting technology is all made of unique coinage technique and dedicated coinage materials all the time to prevent from copying, and
Under the background of globalization, technical equipment, processing method progress are rapid, your gold technology and material composition secrecy are difficult to prevent to
Belong to the imitation of coin, commemorative coin.Current anti-fake mode mainly has:
1. expert-opinion method, the i.e. professional person of coinage anti-counterfeit field are analyzed and researched to RMB application professional equipment and work
Authentication is realized in the identification of skill details, this has high requirement to personnel, and the re-testing periods are longer, and determination rates are lower.
2. components tests method, i.e. the ratio of element and element contained by chemical examination coin judges that the whether professional coinage of coinage materials is closed
Gold.This has higher requirements to equipment, and only professional testing agency just has detectability, and ingredient sampling may be damaged firmly
Coin surface.
Summary of the invention
Of the existing technology in order to solve the problems, such as, the object of the present invention is to provide a kind of on coin or souvenir badge
Micro-structure Antiforge recognizing method, it is true and false that this method can lossless, fast and accurately detect coin, and allows fake producer in existing skill
It can not be copied under the conditions of art.
In order to achieve the above object, the present invention is achieved through the following technical solutions:
A kind of micro-structure Antiforge recognizing method on coin or souvenir badge includes following processing step:
A, coin surface dot matrix information data is worked out simultaneously according to the microcosmic convex-concave geometry trace on the coin surface of every pair of die marks
Extract coding record storage；
B, its textural characteristics is found according to the Shamian Island effect that the coin surface sand-blasting of every pair of die marks is formed and records texture letter
It ceases and extracts coding record storage；
C, coding record storage is extracted according to the etching trace that laser ablation mold or coin are formed；
D, coin figure line elevation information point cloud is formed according to the different height of the coin surface pattern of every pair of die marks to be mentioned
Take coding record storage；
E, according to the trace of the geometrical pattern and coin surface microscopic that are formed in the coin pattern contour of every pair of die marks, coining
Point, line, pattern extract coding record storage；
F, by above- mentioned information formed can quick search database；
G, it identifies and the information that the surface information and a, b, c, d, step e of coin or chapter store is compared as met when true and false coin
For genuine note, it is not inconsistent and is combined into counterfeit money.
The implementation method of the step a comprises the following steps: application photograph or scanning device acquirement coin surface high definition are thin
Information is saved, the convex-concave geometry trace of coin surface microscopic is found by the rgb value and gray value of program analysis coin image, then
The surface microscopic convex-concave geometry trace that has jointly of record the imprinted product of mold, encode in conjunction with co-ordinate position information and by
Different molds are stored in database.
The implementation method of the step b comprises the following steps: application photograph or scanning device acquirement coin surface high definition are thin
Information is saved, the rgb value of coin image is analyzed by program and gray value finds coin surface sand-blasting texture, records texture information,
Texture information is encoded and is stored in database by different molds.
The implementation method of the step c comprises the following steps: the etching trace formed according to laser ablation mold or coin
The unique shape of formation carries out breath coding and is stored in database by different molds.
The implementation method of the step d comprises the following steps: application photograph or three-dimensional scanning device obtain coin exterior view
Line elevation information, in every pair of die marks metal flow can different from, record figure line height change and amplitude can be effectively
Distinguish genuine note and counterfeit money.Database is stored in by figure line height and amplitude change information information coding and by different molds.
The implementation method of the step e comprises the following steps: application photograph or scanning device acquirement coin surface high definition are thin
Save information, the rgb value of coin image is analyzed by program and gray value find coin picture on surface profile, formed in coining it is several
Trace point, the line, pattern-information of what pattern and coin surface microscopic carry out coding in conjunction with co-ordinate position information and by different molds
It is stored in database.
The implementation method of the step f comprises the following steps: the data deposit database that a, b, c, d, step e are obtained is simultaneously
Optimization.
The implementation method of the step g comprises the following steps: applying camera, scanning device and 3-D scanning or photographing device
The detail information for obtaining sample, the information in information and database is compared, and is then genuine note if any meeting, such as
It is then counterfeit money without meeting.
Advantage for present invention is with effect:
The method of the present invention mainly utilizes the Micro texture that coin surface metal flows the convex-concave geometrical morphology to be formed, sandblasting is formed to become
Change, etching trace, the elevation information of coin surface pattern and the pattern of coin, chapter surface that laser ablation mold or coin are formed
Geometric profile carry out anti-counterfeit recognition, above several category features due to its microcosmic property, randomness, be self-assembling formation during coinage
And characteristic information substantial amounts, be difficult inversely make and it is counterfeit, have stronger anti-counterfeit capability.It is not depended on after system is built up anti-
The artificial experience of pseudo- expert, can network detection whenever and wherever possible, and the fast result accuracy rate of detection speed is high, as long as detection installation software
And detecting instrument, can the secondary circulation of in honor of coin anti-fake guarantee is provided.This method will not cause coin product any thin
Micro- damage is especially suitable for the authentication of the high values commemorative coin products such as gold and silver, commemorative coin condition can be kept well complete
It is good.This method fake producer can not copy under prior art conditions, this is because coin surface microscopic first is characterized in by mold
It interacts with coin blank cake and to be formed, and every pair of mold is due to turning over the difference of metal flow and the slight change of processing conditions
It will have any different, all kinds of forms, shape are numerous on coin surface microscopic in addition, and fake producer can not copy one by one, and due to anti-
Puppet point belongs to microcosmic point, is difficult inversely to make on coin surface, (seeing that coin makees mold).The method of the present invention passes through to mold
The minutia of self-assembling formation is encoded and is stored in the intrinsic feature and coining on surface, by sample and in advance when identifying the true and false
It stays coding to be compared, distinguishes the true and false.Due to anti-fake point be mold it is exclusive or coining in self-assembling formation, copy possibility it is extremely low,
It can achieve the antifalse effect for allowing fake producer that can only imitate its type and its mind can not being imitated in the process of the present invention.To sum up, the present invention has
There are stronger practicability and higher anti-counterfeit capability.
