It is preferred that, the information code respectively with some grades of GTGs is read from identification region according to the shape of described information code element
Member.For example, described information code element is shaped as rectangle.It is preferred that, being shaped as described information code element is square.It is preferred that, it is described
The size of information code element is set according to GTG quantity.For example, the size of described information code element is directly proportional to GTG quantity, and for example,
Ratio is determined according to default experience ratio table.And for example, the size of described information code element is determined according to the identification region.For example,
Identification region is square, is classified as x2It is individual square；For example, the identification region is 3*3 square centimeters, 9 sides are classified as
Shape, the size of each square as described information code element, i.e., 1 square centimeter；And for example, be classified as 36 it is square, it is each square
The as size of described information code element, i.e., 0.25 square centimeter.These corresponding relations only need to be pre-set.And for example, root is gone back
The size of described information code element is determined according to number of colours.For example, the size of described information code element is inversely proportional with the number of colours,
The number of colours is bigger, and described information code element is smaller.It is preferred that, determine described information code element always according to the GTG quantity
Size.For example, the size of described information code element is inversely proportional with the GTG quantity, the GTG quantity is bigger, described information code
Member is smaller.So, an information code element can accommodate bigger information content.
And for example, the recognition methods, it comprises the following steps：Obtain many GTG invisible two-dimensional codes；Read from identification region
Respectively there are some colors and each color has the information code element of some grades of GTGs, output is encoded data after decoding.Wherein, if
Do color and there are each color some grades of GTGs to give information code element or many GTG invisible two-dimensional codes or the color of identification region
Color quantity.For example, read from identification region with the information code element of red and black double colour and each color with 96 grades of GTGs,
Its a total of 96*2=192 seed color；And for example, read from identification region with red-black two kinds of basic colors and each is basic
Color has the information code element of 96 grades of GTGs, its a total of 96*2=192 kinds subdivision color.Or, it will be appreciated that it is, according to described
Number of colours and the GTG quantity, identification is with some basic colors and each basic color combines some grades of GTGs, so as to combine
Form some colors or be sub-color or be segment color information code element.
For example, the various subdivision colors that cooperation of the color including basic color and GTG is obtained, the number of colours bag
Include basic chromatic number amount.Wherein, the basic color is some basic colors, for example the basic color of RGB three, and for example, per color
Coordinate 12 GTGs, then a total of 36 kinds of colors.For example, basic color cooperatively forms the GTG of relevant rudimentary color from different GTGs
Colour system.And for example, each basic color is determined by the number of colours, i.e., described basic color is related to the number of colours.For example,
The number of colours is 3, corresponding, and the color includes 3 kinds of basic colors；And for example, the GTG quantity is 16, i.e., including 16 grades
GTG, so, a total of 48 kinds of colors of identification region of many GTG invisible two-dimensional codes.And for example, the number of colours is 8, described
GTG quantity is 64, i.e., described number of colours includes 8 kinds of basic colors, and every kind of basic color has 64 grades of GTGs, totally 512 kinds of colors or
Segment color.And for example, the corresponding basic color of number of colours, example are determined according to the basic chromatic number amount mapping table of color 2 D code
Such as, each basic chromatic number amount in the table to should quantity basic color, for example, according to number of colours and the basic color of basic color
Quantity mapping table, corresponding basic color information is obtained according to number of colours, for example, number of colours is 3, what correspondence was pre-seted
3 kinds of basic color RGB, and for example, number of colours is 7, and 7 kinds of basic colors that correspondence is pre-seted, the yellowish green ultramarine of such as blood orange is purple, for example,
Basic chromatic number amount is 8,8 kinds of basic colors that correspondence is pre-seted, and and for example, basic chromatic number amount is 8, and corresponding basic color is that blood orange is yellowish green
Ultramarine purple indigo；And for example, basic chromatic number amount is 64 or 128, and corresponding basic color is the correlation set by each image processing software
Colour system, by that analogy.For example, the number of colours is 256, the GTG quantity is also 256, then a total of 65536 kinds of colors,
I.e. each basic color includes the color of 256 kinds of different GTGs, and each GTG is to that should have the color of 256 kinds of different basic colors.
Under normal circumstances, using number of colours as storage information factor when, if number of colours is higher, follow-up
Identification process in, the requirement to hardware device is higher, and has the advantages that information capacity is big；Can also be only with grey exponent number
The factor as storage information is measured, now color is intended only as the form of expression of many GTG invisible two-dimensional codes, its essential storage
Information is grey Quick Response Code, gray processing processing is carried out to image during identification, without considering color factors.
For example, being the various basic color parsing GTG quantity in the identification region of many GTG invisible two-dimensional codes；And for example, it is more grey
The identification region of rank invisible two-dimensional codes only configuration information area, deposits location information in the information area；Or deposited in the information area
Positioning area.For example, parsing number of colours and GTG quantity for the identification region of many GTG invisible two-dimensional codes；And for example, by the color
Color quantity determines each basic color, i.e., described basic color is related to the number of colours.And for example, it is many GTG invisible two-dimensional codes
Identification region parsing number of colours and GTG quantity.And for example, it is the identification region parsing of many GTG invisible two-dimensional codes and ash more
The GTG quantity that the number of colours of rank invisible two-dimensional codes matches, for example, the GTG quantity is equal with the number of colours.Again
Such as, the identification region of many GTG invisible two-dimensional codes is parsed always according to the GTG quantity.And for example, according to GTG quantity
The size of the identification region is adjusted flexibly.For example, the identification region is directly proportional to the GTG quantity, in the present embodiment,
The size of many GTG invisible two-dimensional codes is not a rated value, but is flexibly set according to GTG quantity, can be with practical application
Make a width very big pictorial poster；It is preferred that, the positioning grid that the pictorial poster is viewed and admired without obvious, obstruction, so that as many
GTG invisible two-dimensional codes are used.
It is preferred that, when obtaining many GTG invisible two-dimensional codes, the letter is also determined by the shape mark in described information area
Cease the shape of code element.For example, the shape of described information code element is set according to the GTG quantity, for example, the GTG quantity is got over
Greatly, the edge of the shape of described information code element is more；And for example, the GTG quantity is bigger, and the shape of described information code element is more multiple
It is miscellaneous；And for example, the shape of described information code element has some convex portions, and the GTG quantity is bigger, and the convex portion of described information code element is got over
It is many；It is preferred that, the convex portion quantity of described information code element is equal with the GTG quantity；It is preferred that, each described information code element is set
Positioning area described in one is put, using the positioning area of the convex portion as described information code element.For example, the convex portion is essentially
Pixel grid, the pixel grid on its both sides is colourless or light color, and the convex portion is dark color.It is preferred that, according to the grey exponent number
Amount sets the size of described information code element.For example, the size of described information code element is inversely proportional with the GTG quantity, for example, institute
State GTG quantity bigger, described information code element is smaller.
It is preferred that, also include step after many GTG invisible two-dimensional codes of acquisition：Denoising, by denoising to obtain more preferable knowledge
Other effect.For example, carrying out the denoising using mean filter.It is preferred that, the denoising is carried out using geometric mean filtering.Again
Such as, the denoising is carried out using smothing filtering.It is preferred that, the denoising is carried out using nonlinear smoothing filtering.It is preferred that, use
The mode of many GTG invisible two-dimensional codes is quickly continuously acquired simultaneously, similar to the continuous shooting mode that interval time is extremely short, obtains multiple
Many GTG invisible two-dimensional codes, are overlapped, and then perform the denoising.So, more accurately denoising effect can be obtained.It is preferred that
