Embodiment two
The method that anti-counterfeiting detection is realized by color-shifting images that the embodiment of the present invention two is provided, with two detections
Exemplified by position, the implementation process of anti-counterfeiting detection is illustrated, as shown in figure 3, comprising the following steps：
Step S201：Detected material enters transmission channel by introducing port.
For example, by taking RMB as an example, the introducing port (ratio that detected banknote is passed through into anti-counterfeiting detection equipment
Such as note input mouthful) transmission channel is imported, and be transferred to by transmission channel at the position of anti-counterfeiting detection.
Step S202：When detected material reaches the specified location in Transfer pipe, detect at thing to be detected
When the first detecting position, colouring information of the region to be detected under light source irradiation on thing to be detected.
Being generally detected as thing location in transmission channel enables to detected material to be in vertical inspection
The position of survey, therefore, the first detecting position are usually vertical detection position, certainly if not in vertical inspection
Location, can also be adjusted by rotary unit, or first in the inspection non-perpendicular to detected material surface
Location is detected.
Step S203：Control detected material rotation makes it rest on the second detecting position.
The second detecting position and the first detecting position rotated to is at an angle, in order to from different observation
Detected at angle.
Step S204：When detecting that thing to be detected is in the second detecting position, region to be detected exists on thing to be detected
Colouring information under light source irradiation.
Assuming that the first detecting position is vertical detection position, then the second detecting position is non-perpendicular detecting position, it is assumed that the
One detecting position is non-perpendicular detecting position, then it is contemplated that the second detecting position is adjusted to vertical detection position.So as to
Realize perpendicular to detected material surface and the inspection non-perpendicular to the two different observation angles of detected material surface
Survey.
Above-mentioned steps S202- steps S204 realizes the specified location in detected material reaches Transfer pipe
When, control detected material rotation makes it rest on two different detecting positions；Detect respectively at thing to be detected
When two different detecting positions, colouring information of the region to be detected under light source irradiation on thing to be detected.
Wherein, a detecting position is realized is detected with the view angle perpendicular to detected material surface to detected material,
Another detecting position is realized and detected material is detected with the view angle non-perpendicular to detected material surface.
It can specifically be realized by the rotary unit set in anti-counterfeiting detection equipment.
The characteristics of due to color shifting ink is perpendicular to detected material surface observation and non-perpendicular to detected
Two kinds of different colors are presented during thing surface observation, therefore, when region to be detected is color shifting ink pattern,
Control detected material rotation it is rested on two different detecting positions, in order to perpendicular to it is non-perpendicular
View angle in detected material surface is detected respectively to detected material.
As shown in figure 4, the light on new edition RMB becomes hollow out opened window safety line, vertical nominal value is viewed as red
Color, is green with nominal value angled (non-90 degree).Therefore false proof inspection is being carried out to new edition RMB
During survey, hollow out opened window safety line can be become by detection light perpendicular to nominal value and angled with nominal value
Color when (non-90 degree) realizes the discriminating of the true and false, if vertical nominal value is viewed as red, with nominal value
Angled (non-90 degree) is that green is then true, is otherwise false.
Step S205：According to the colouring information got determine respectively thing to be detected in each detecting position it is to be checked
Survey the color in region.
The light got during by the first detecting position and the second detecting position becomes the color letter of hollow out opened window safety line
Breath passes to the unit for carrying out color measuring and calculating processing, carries out the identification measuring and calculating of color, to determine in the first inspection
The light detected when location and the second detecting position becomes the color of hollow out opened window safety line.
Step S206：The color in thing to be detected region to be detected in each detecting position that judgement is determined is no
For specified color.
When being judged as YES, step S207 is performed；Otherwise, step S208 is performed.
For example：When the first detecting position is perpendicular to the detecting position of nominal value, judge that the light detected becomes hollow out
Whether the color of opened window safety line is red；And in the second detecting position non-perpendicular to nominal value, detect
Light become hollow out opened window safety line color whether into green.
Step S207：It is true to determine detected material.
Assuming that when the first detecting position is perpendicular to the detecting position of nominal value, light becomes the color of hollow out opened window safety line
For red；And in the second detecting position non-perpendicular to nominal value, light becomes the color of hollow out opened window safety line to be green
Color, then the banknote is genuine notes.
Step S208：It is false to determine detected material.
Assuming that when the first detecting position is perpendicular to the detecting position of nominal value, light becomes the color of hollow out opened window safety line
It is not red；Or in the second detecting position non-perpendicular to nominal value, light becomes the color of hollow out opened window safety line not
It is green, then the banknote is counterfeit money.
Above-mentioned steps S206- steps S208 is realized to be treated according to the thing to be detected determined in each detecting position
The color of detection zone judges the true and false of thing to be detected.
Embodiment three
The method that anti-counterfeiting detection is realized by color-shifting images that the embodiment of the present invention three is provided, with three or three
Exemplified by detecting position more than individual, the implementation process of anti-counterfeiting detection is illustrated, as shown in figure 5, including such as
Lower step：
Step S301：Detected material enters transmission channel by introducing port.
For example, by taking RMB as an example, the introducing port (ratio that detected banknote is passed through into anti-counterfeiting detection equipment
Such as note input mouthful) transmission channel is imported, and be transferred to by transmission channel at the position of anti-counterfeiting detection.
Step S302：When detected material reaches the specified location in Transfer pipe, detect at thing to be detected
When the first detecting position, colouring information of the region to be detected under light source irradiation on thing to be detected.
Being generally detected as thing location in transmission channel enables to detected material to be in vertical inspection
The position of survey, therefore, the first detecting position are usually vertical detection position, certainly if not in vertical inspection
Location, can also be adjusted by rotary unit, or first in the inspection non-perpendicular to detected material surface
Location is detected.
Step S303：Control detected material rotation makes it rest on next detecting position.
The next detecting position rotated to and a upper detecting position are at an angle, in order to from different
View angle is detected.
Step S304：When detecting that thing to be detected is in next detecting position, region to be detected on thing to be detected
Colouring information under light source irradiation.
Assuming that the first detecting position is vertical detection position, then other detecting positions are non-perpendicular detecting position, it is assumed that the
One detecting position is non-perpendicular detecting position, then it is contemplated that a detecting position in other detecting positions is adjusted to vertical
Straight detecting position.It is perpendicular to detected material surface and multiple not non-perpendicular to detected material surface etc. to realize
With the detection of observation angle.
Step S305：Whether the detecting position of all settings has been detected.
If so, performing step S306；Otherwise, return and continue executing with step S303, carry out next inspection
