Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
Fig. 1-4 is please referred to, the present invention provides a kind of technical solution: when dynamic two-dimension code is worked out, by one group of longer needs
The information that the information of displaying is divided into multiple groups short, the maximum length of every group of short message can be 8,16,32,64 and 128 characters
Deng.
Dynamic two-dimension code is made of several static two dimensional codes, and every width static two dimensional code may include or part includes a component
Short information after cutting, and showing by certain sequence order, when identification, the short information after being identified is by corresponding sequence
Information before being reassembled into segmentation.
The structure of each witness marker on recognizable frame in dynamic two-dimension code is identical, each witness marker by with
Lower element is constituted: three concentric locating circles and three data circles；The central point of three concentric locating circle is as static two dimensional code
Identify basic point；Innermost layer setting circle includes three data circles, and three data circles are arranged successively and mutually indepedent, intermediate data
Circle is concentric with setting circle；Data circle is corresponding with quick identification code, and each data circle represents a data of quick identification code；
Again include bowlder when the identification software (hereinafter referred to as mobile phone) of identification equipment recognizes in a certain data circle, will quickly identify
It is set to 1 with the data of corresponding position of data circle in code, otherwise to be set to 0.
According to current identification condition, quick identification code in dynamic two-dimension code, by (3+6), totally 9 bytes are formed；1st to
3 bytes be referred to as frame information coding, for identify this can recognize frame on relevant information and message length encoded, last 6
A byte is referred to as frame sequence coding, thus dynamic two-dimension code present case at most can recognize that frame forms by 64 width；?
In the case that identification technology develops, it can be extended, at this moment frame information is encoded to binary one 11B, if frame is believed
Breath is encoded to binary one 11B, then it represents that this is encoded to extended coding；The software that quick identification code can be identified in equipment is fast
Speed identification.
Recognizable frame in dynamic two-dimension code is played by frame sequence coded sequence；When the frame sequence that can recognize frame is compiled
When code is 0, representing this can recognize that frame is that the first width can recognize frame；When the frame sequence that can recognize frame is encoded to 1, indicate that this can
Identification frame is that the second width frame can recognize frame；When the frame sequence that can recognize frame is encoded to 63 (2 6 powers), indicate that this can recognize
Frame is that last width can recognize frame.
Unlike common static two dimensional code, it can recognize that the static two dimensional code on frame does not include the fault-tolerant of redundancy
Information can recognize that the fault-tolerant of frame is compensated by transportable frame；It can recognize that each region on the static two dimensional code on frame is last
8 byte datas for examining, hereafter referred to collectively as CRC data, CRC data is for examining whether some region of data are known
It is not wrong；When mobile phone identifies the static two dimensional code on recognizable frame, discovery CRC is incorrect, can be by can with this
Data on the corresponding transportable frame of identification frame compensate identification.
Also there are three witness markers on each width transportable frame, one of them is to be fixed on the upper right corner, another two witness marker
It is then moveable, the structure of the witness marker on each width transportable frame is also such as recognizable frame, by concentric circles and data
Circle composition；On Far Left witness marker on each width transportable frame and bottom witness marker and recognizable frame be it is the same,
And be made of three concentric circles and three data circle, but the witness marker of rightmost then by three concentric circles outside and two numbers
It is formed according to circle；Far Left witness marker and bottom witness marker on each width transportable frame can working as with dynamic two-dimension code
Preceding frame number is changed and is changed, but is located at top and bottommost forever；Data circle on transportable frame corresponds to an octet
Data, we are hereafter referred to collectively as mobile frame position to the data, and mobile frame position is used to indicate the position that the transportable frame moves,
That is Far Left witness marker is at a distance from rightmost witness marker, using one two-dimensional code data as basic unit；Mobile framing bit
It sets and compensates identification for the partial data to the transportable frame；Transportable frame also acts as number other than playing vision buffer effect
According to compensating action.
After mobile phone is identified all recognizable frames in dynamic two-dimension code, by the decoding on all recognizable frames
Information is reorganized according to the sequence of the frame sequence coding on recognizable frame, before recovering dynamic two-dimension code coding
Information.
Due to identifying that each width can recognize that frame and transportable frame need certain time, and the fast speed that frame is mobile, so
When handset identity dynamic two-dimension code, and method for distinguishing is known immediately without using capturing immediately, but only identify and can recognize on frame immediately
Quick identification code.After mobile phone captures a certain frame of dynamic two-dimension code, first judge that the frame is to can recognize frame or move
Frame then only saves the frame if it is transportable frame, waits the recognizable frame (0 to last width of all sequences in the dynamic two-dimension code
Can recognize frame) it is identified together after whole captured；The quick identification code on the frame is then first quickly judged if it is recognizable frame,
And record the analog value of the coding of the frame sequence in the quick identification code, then equally only save the frame and simultaneously nonrecognition this can know
On other frame, the recognizable frame (0 to last width can recognize frame) of all sequences in the dynamic two-dimension code is waited all to be captured
It is another afterwards to play identification.Thus dynamic two-dimension code can be identified in a relatively short period of time.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
