A kind of coding mode, it is distributed at plane (on two-dimensional directional) chequered with black and white according to certain rules with certain specific geometric figure
Graphic recording data symbol information, in code compilation dexterously using constitute computer-internal logical foundations " 0 ", " 1 "
The concept of bit stream indicates text numerical information using several geometrical bodies corresponding with binary system, defeated by image
Enter equipment or photoelectric scanning device automatically identifying and reading to realize automatic processing of information.It can be deposited more than traditional Bar Code bar code
More information can also indicate more data types.However planar bar code technology data capacity used at present is small, in order to increase by two
Tie up code data capacity, a kind of mode is two dimensional code to be made to very big, but do big two dimensional code and can occupy too many area；Another kind side
Formula is the point of two dimensional code to be made small, however the information of two dimensional code is stated, depending on black and white lattice in two-dimensional bar code figure
Publication and area, the feature make it in recognition, require the acquisition of its figure to become very high, usual fine definition and low abnormal
Change is the most fundamental requirement, if doing the point of small two dimensional code, is unfavorable for the correction of scalloping, while also by the limit of resolution ratio
System.
It proposes in the prior art and barcode data capacity is increased by the processing of colour barcode, such as publication No. is CN
The technology contents of 102147873A, in such technology by quaternary information in Color Expression encoded data stream (i.e. 0,1,2,
3) bar code reading requirement, is reduced, data information capacity is improved.However the content in patented technology is laid particular emphasis in conventional color bar code
On the basis of be implanted into picture, enhance the form of expression, for still having deficiency in the transformation of bar code itself.
Therefore, in view of the foregoing drawbacks, need to improve the prior art.
