Fig. 3 is flow process signal of the present invention based on another embodiment of the data transmission method of Quick Response Code
Figure, as shown in figure 3, the embodiment is included based on the data transmission method of Quick Response Code：
S301, transmitting terminal directly carry out continuous programming code to Frame to be sent.
Wherein, the Frame after coding can be two-dimentional code character, and the two-dimentional code character includes M*N two
Dimension code element.
In a specific example, information to be sent (is referred in mobile terminal with two by transmitting terminal first
System or 2 the multiple system such as quaternary, octal system, data such as hexadecimal) read collection
In internal memory, then according to 8 one group (also can be according to 16 one group) be compiled to information to be sent
Group, eventually forms the array of some 8x8.
Then, as shown in figure 4, the data of the array of above-mentioned some 8x8 are converted to two-dimentional yardage
According to obtaining several little two-dimensional code datas units, afterwards, by digital independent order several young waiters in a wineshop or an inn
Dimension code data element is arranged, and constitutes a dynamic two-dimension code Frame.
S302, transmitting terminal carry out duplicate removal compression to coded data frame.
In a specific example, each array is a two-dimentional code element (possessing Quick Response Code feature),
One frame data include the N number of two-dimentional code elements of M x.Two-dimentional code element has certain difference with traditional Quick Response Code,
For example：Dynamic two-dimension code cannot be recognized in conventional two-dimensional code identification software, but dynamic two-dimension code
Recognizer can recognize conventional two-dimensional code.Reason is, for more Quick Response Code identical permutation, to give birth to
When into M x N arrays, need to be compressed algorithm (duplicate removal), therefore in this embodiment
Two-dimentional code element is not fully identical with original Quick Response Code.As shown in figure 5, for same content
Can at most reduce by 2/3 redundancy after (character category information) compression.
Frame after compression is filled into display device according to temporal order by S303, transmitting terminal successively
On, and the area that occupies of each time data frame number group is less than or equal to the face of used display device
Product.
S304, transmitting terminal continuously transmit Frame to receiving terminal according to temporal order.
Wherein, Frame includes data frame identification ID, for one Frame of unique mark, and leads to
Cross the mark ID and show temporal order；
S305, if the Frame that receiving terminal is received is not according to the temporal order, receiving terminal
Continue to, till receiving all Frames.
S306, is decoded after be ranked up by the Frame for receiving successively
To the initial data frame.
In this embodiment, also it is capable of achieving random data frame sequence to receive, receiving terminal can be in transmitting terminal
Remaining data frame is continued in the case of non-sequential transmission Frame, strengthens the robustness of communication.Together
When, transmitting terminal and receiving terminal can carry out the transmission of data without the need for network connection, without to existing
Equipment is transformed, and compares conventional two-dimensional code data transmission method, the embodiment based on Quick Response Code
Data transmission method in data transmission capacity, speed, operation complexity have and change greatly very much
Enter.
Fig. 6 is that the present invention is shown based on the flow process of one Application Example of data transmission method of Quick Response Code
It is intended to, as shown in fig. 6, in this embodiment it is assumed that user A needs to send one to user B
File, for example, a WORD document.
First, user A mobile phones are directly encoded to the data in WORD documents, and according to
Preset rules and order encoded translated for several Frames, for example, several two-dimentional code elements,
This several Frame can constitute M x N arrays (M, N are natural number)
Secondly, the optimum resolution for playing that display device is supported is determined by optimized algorithm, then is pressed
Successively the Frame for obtaining is filled on display device according to order.For example：Frame constitutes M x N
Array (M, N are natural number).The area (or pixel) that each time data frame number group is occupied
It is less than the area (or pixel) equal to the display device for being used.
Then, user B mobile phones by image collecting device, for example, send out by photographic head, continuous reception
The continuous programming code data frame information that end sends is penetrated, and according to default coding rule and sequence, logarithm
Decoding operate is carried out according to frame, original WORD document datas information is obtained.
Wherein, user B can set up secondary connection (for example：Networking operation) can receive
Information entrained by data source.
In addition, the Frame that user's B mobile phones are such as received does not have according to predefined procedure (for example：From
Sequence is from 1,2,3 ... in the data of N, starts to receive from k-th frame, K<N, and K, N
For natural number), user B mobile phones can be continued to, till receiving all Frames.Therefore,
Realize 1:1 or 1：The data transmission capabilities (broadcast type) of N, while, there is provided it is a certain degree of
Transmission robustness.
In data transmission method of the present invention based on Quick Response Code another Application Example, Ke Yitong
Cross optimized algorithm and determine broadcasting display device display effect, for example, can be determined by adaptive algorithm
Optimum data frame-screen accounting, Frame-screen accounting (may be simply referred to as：Screen accounting) may be defined as
Elemental area shared by Frame/target terminal screen pixels area.As pixel is imitated in different terminals
Fruit is different, therefore needs to redefine suitable screen accounting before transmitting data frame.
In this embodiment, the cardinal principle that self adaptation screen is accounted for be when draw per data frame cut-off rule when,
Vertical line is suitably moved left and right, and horizontal line is moved up and down to an optimum position.As a example by drawing vertical line, if
I-th gray value for arranging pixel from top to bottom constitutes column vector Vi,
Wherein, average lengths of the m for all row of screen area, i spans are all for image-region
Capable average length, defining the cost for moving to i+1 row from the i-th row is
In above-mentioned formula (2)The XOR of adjacent block row is represented, when i is handed over positioned at 2 modules
When on line, formula (2) takes peak value.One minimum of setting, obtains step-length according to averaging method,
The general area of optimal segmentation line is obtained, in this region, enters line slip from left to right, slided
When calculate peak value.When peak value is less than minima, continue to slide.Otherwise current location is for most
Best placement.Fig. 7 show unused self adaptation screen accounting and the cut-off rule using self adaptation screen accounting
Alignment condition, it can be seen that using self adaptation screen accounting, can make Frame preferably adapt to end
End screen pixels segmentation.
In this embodiment, transmitting terminal display device is adapted to by self adaptation, transmitting terminal can be avoided to show
Show the redundancy or the buffering caused as Frame capacity is higher than the maximum pixel of display device of equipment
Overflow.
