Below enumerate two kinds of two-dimensional bar codes commonly used.Shown in Figure 1 is National Standard GB/T 17172-1997 417 barcodes " regulation 417 barcode master drawings, 417 barcode maximum storage capacities are 1850 English characters, belong to the stack two-dimensional bar code, promptly pile up and form, be adapted to the laser raster scan mode and distinguish by the bar code of a series of compressions; Shown in Figure 2 is National Standard GB/T 18284-2000 quick response matrix code " regulation the quick response matrix code master drawing, the quick response matrix code maximum storage capacity is 2953 bytes, belong to matrix two-dimensional barcode, promptly the two-dimensional matrix that is spliced by the series of rectangular module is adapted to planar array type photoelectricity image sensor and distinguishes with shooting style.
Along with fast development of information technology, various high-resolution, high brightness computer display are universal day by day, and the handheld mobile devices such as mobile phone with high-resolution camera function also are used widely.Putting before this, the invention discloses a kind of data capacity is the colour matrix sign indicating number and the coding and decoding method thereof of tens of times of traditional monochromatic two-dimensional bar code data capacities, and, realize data form computer is transferred to the method for handheld mobile device based on the mode of this colour matrix sign indicating number with " visible just the bat obtains ".
Generally speaking, the sign indicating number figure of two-dimensional bar code is divided into recognition feature district, assist location characteristic area, parameter memory block and data storage area according to function.417 barcodes as shown in Figure 1,101 is the recognition feature district, and 102 is the parameter memory block, and 103 is the data storage area; Quick response matrix code as shown in Figure 2,201 is the recognition feature district, and 202 is the assist location characteristic area, and 203 is the data storage area.The recognition feature district has specific geometric properties, and purpose is to adapt to the image model recognizer of computer vision system, locatees described two-dimensional bar code fast with rational software and hardware resources; In order to guarantee to discern the large scale bar code reliably, bar code keeps some zones that are used to place the assist location feature, and image recognition algorithm further carries out geometry to image according to these assist location features and corrects; The parameter memory block is used to store the various parameters of two-dimensional bar code self, these parameters comprise information such as the logic size of bar code and data capacity, in decode procedure, need to use these parameters, for guaranteeing that decoding obtains correct parameter, before storing parameter into the parameter memory block, the forward error correction coding algorithm that the maintenance data communication field is commonly used is encoded to parameter; Storage data in data storage area obtain correct data for guaranteeing decoding, before the data storage area, use the forward error correction coding algorithm that it is encoded in storage equally.On structure, the basic structural unit of matrix two-dimensional barcode is a module, and the module of classical matrix formula two-dimensional bar code is only got " bright " or " secretly " two kinds of colors.The storable data bit numerical digit of each module is log
2C, wherein C is the desirable chromatic number of module.For example the storable data bit number of black and white module is log
22=1, the data bit number that one 4 look module is represented is log
24=2.
As shown in Figure 4, the invention discloses a kind of colour matrix sign indicating number.Wherein, 401 is the recognition feature of described colour matrix sign indicating number, and 402 is the parameter memory block of described colour matrix sign indicating number, and 403 is the assist location feature of described colour matrix sign indicating number, and 404 is the data storage area of described colour matrix sign indicating number.
Recognition feature 401 is made up of by arrangement mode shown in Figure 3 the rectangular module of four kinds of colors, and described four kinds of colors are only synthetic by two kinds of primary colours, and wherein, 301 is black, and 302 is that primary colours 1,303 are that primary colours 2,304 are the color that primary colours 1 and primary colours 2 synthesize.Therefore, in the passage of primary colours 1, described recognition feature shows as the wide striped that light and shade replaces on the horizontal direction, in the passage of primary colours 2, described recognition feature shows as the wide striped that light and shade replaces on the vertical direction, this separate on the color space, the feature of overlapping, orthogonal on the geometric coordinate, wide striped that light and shade replaces, promptly be the recognition feature of described colour matrix sign indicating number.
Parameter memory block 402 is used to store the value of described colour matrix sign indicating number variable element, and these variable elements comprise the line number of colour matrix and columns, the length of data that the data storage area is stored, the kind number that the data storage area module is used color etc.Because the value that the parameter memory block is used to store described colour matrix sign indicating number variable element, therefore the parameter of parameter memory block self must be arranged in specific embodiment in advance, and these agreements comprise the color of parameter memory block module use, the parameter of forward error correction coding algorithm etc.
Assist location feature 403 is with respect to the fixed-site of recognition feature 401, and the color value of each module is by its place coordinate constraint.The effect of assist location feature is to provide coordinate reference and color reference for the data module away from recognition feature.
Data storage area 404 is the zones that are used to store data, and the data storage area module is used color representation ability, color detection ability and the desired data density Dynamic Selection of the kind number of color according to application system.If the color representation ability of application system or color detection ability then should reduce the kind number of color, and use the color of wavelength dispersion as far as possible; If application system needs large data capacity, then increase the kind number of color, store the length of data to improve each data module, thereby reach the purpose that improves data capacity.
Fig. 5 is the computer program flow chart that encodes the data to described colour matrix sign indicating number.Process 501 is according to the line number and the columns of the calculation of parameter colour matrix such as chromatic number of data length to be encoded, data module use, and the parameter that is used for the forward error correction coding algorithm of data to be encoded; Process 502 generates two-dimensional matrix in internal memory, a module of the corresponding described colour matrix sign indicating number of each element of matrix, the color value of described element storage respective modules; Process 503 is dressed up the parameter Bit String with line number and columns, the chromatic number of data module, the parameter group such as length of data of matrix, utilization forward error correction coding algorithm is filled into the parameter memory block to this parameter Bit String coding with the parameter Bit String behind the described coding; Process 504 usefulness forward error correction coding algorithms are encoded to data, and the data behind the described coding are filled into the data storage area; Process 505 converts described two-dimensional matrix to raster graphic formatted file, end-of-encode.
The raster graphic file that above-mentioned cataloged procedure obtains can directly show with Electro-Optical Display, or is printed on paper and other medium, so computer data has obtained performance with the form of colour matrix sign indicating number.In order to obtain its coded data from described colour matrix sign indicating number, need to obtain the image of described colour matrix sign indicating number with recognizing apparatus, and to its decoding.Fig. 6 is the system block diagram of described recognizing apparatus, and wherein, 601 is the display medium of colour matrix sign indicating number, and 602 is the colour matrix sign indicating number, and 603 is planar array type color photoelectric image sensor, is used to aim at 602 and receive its light of initiatively launching or reflected ambient.Central processing unit 604 chain of command configuration color photoelectric image sensors 603 are gathered coloured image under the view finding pattern, and the image that collects is presented on the color monitor 605 in real time, with guides user aiming colour matrix sign indicating number 602, and make planar array type color photoelectric image sensor 603 and colour matrix sign indicating number 602 keep suitable distance, to obtain the optimal imaging effect.Press fast gate control 606, central processing unit 604 chain of command configuration color photoelectric image sensors 603 are gathered piece image with optimal parameter, image is stored in the random asccess memory 607, and central processing unit 604 operation decoding software modules are to picture decoding and obtain data.Nonvolatile memory 608 is used for stored program and data.
Because there are two main inherent characteristics in photo electric imaging system:
1, according to " near big and far smaller " basic principle of perspective imaging, if three planes at the lens of colour matrix sign indicating number, planar array type color photoelectric image sensor and sensitive chip place thereof are not parallel, then the image of the colour matrix sign indicating number of Huo Deing is not a rectangle, the module size near from camera lens is big, the module size far away from camera lens is little, therefore under the normal mode of operation, inevitably there is geometric deformation in the image of the colour matrix sign indicating number of acquisition;
2, signal is through the transfer process of electrical-optical-electricity, and the colour matrix sign indicating number in the image that is obtained is compared with the original color square matrix code and certainly existed aberration.
So the picture decoding of the colour matrix sign indicating number that planar array type color photoelectric image sensor is collected is the process of a complexity.
For the colour matrix sign indicating number of successfully decoding, must solve following 3 subject matters:
1, how in image, to locate the colour matrix sign indicating number, and discern its anglec of rotation;
2, how to discern the geometric deformation degree of colour matrix sign indicating number each several part, and it is corrected;
3, the aberration of correcting color square matrix code how.
After addressing these problems, i.e. the described colour matrix sign indicating number of restructural, and then obtain data according to the inverse process decoding of the described colour matrix sign indicating number of Fig. 5 cataloged procedure.To openly the present invention is directed to the solution of the problems referred to above below.
The process of the recognition feature of colour matrix sign indicating number is surveyed in Fig. 7 explanation in image.701 is the recognition feature of colour matrix sign indicating number described in the image, as previously mentioned, described recognition feature possesses the feature of the wide striped overlapping, orthogonal on separation, geometric coordinate on the color space, that light and shade replaces, therefore, from recognition feature 701, extract above-mentioned primary colours 1 channel image, obtain gray scale image 702, from recognition feature 701, extract above-mentioned primary colours 2 channel image, obtain gray scale image 703; Gray scale image 702 binaryzations are obtained black and white binary image 704, gray scale image 703 binaryzations are obtained black and white binary image 705; On the horizontal direction of black and white binary image 704, survey " Bai-Hei-Bai-Hei-Bai-Hei-Bai-Hei-Bai " sequence, the abscissa of the central point 706 of sequence is exactly the center abscissa of described recognition mode, survey " Bai-Hei-Bai-Hei-Bai-Hei-Bai-Hei-Bai " sequence on the vertical direction of black and white binary image 705, the ordinate of the central point 707 of sequence is exactly the central longitudinal coordinate of described recognition mode; Centre coordinate with the described recognition mode that detects is a basic point, on a plurality of directions, survey " Bai-Hei-Bai-Hei-Bai-Hei-Bai-Hei-Bai " sequence through described basic point, the path of the sequence process that the scan line vertical with striped detects is the shortest, the path of the sequence process that detects less than scan line 709 of the path of the sequence process that detects of scan line 708 for example, therefore described path the deflection of short scan line be exactly the anglec of rotation of recognition feature, the described anglec of rotation also is the anglec of rotation of described colour matrix sign indicating number in image.
The recognition mode of described colour matrix sign indicating number is by behind the successful location, obtains the width w of module with the width of described recognition mode divided by the number of modules on its column direction, obtains the height h of module divided by the number of modules on its line direction with the height of described recognition mode.Because of the assist location feature of described colour matrix sign indicating number is fixed with respect to the coordinate of its recognition feature, so can be according to the module width w of aforementioned calculation gained and the coordinate of height h estimation auxiliary positioning module, the module of the assist location feature far away more apart from recognition feature, the error of its estimation coordinate is big more.Again because of the coordinate decision of the color of the module of described assist location feature by the module place, and the color difference of the module of two adjacent assist location features, so available colouring information is finely tuned the coordinate of the module of assist location feature, outwards determine the coordinate of whole modules of assist location feature one by one by the center of colour matrix sign indicating number.Thereafter, the coordinate of data module can draw with interpolation calculation according to the coordinate of auxiliary positioning module.So far, realized geometric correction to described colour matrix sign indicating number image.
Therefore as previously mentioned, the colour matrix sign indicating number in the image that is obtained is compared with the original color square matrix code and is certainly existed aberration, before the module reading of data of the data storage area of colour matrix sign indicating number, must proofread and correct the color of described data module.For this reason, introduce following updating formula:

8After this described updating formula of substitution, proofreaies and correct the color of data module with described updating formula.
Fig. 8 is the computer program flow chart of decoding restoring data from image.Process 801 is according to the detection method location recognition mode of above-mentioned recognition mode, and the anglec of rotation of definite colour matrix sign indicating number; Process 802 reads parameter from the parameter memory block, and utilization decoding FEC algorithm instructs the subsequent decoding process to the parameter error correction with the parameter that obtains, if parameter error correction failure, then decode procedure finishes; Process 803 is determined the module coordinate of assist location feature according to preceding method, then, is benchmark with the coordinate of described auxiliary positioning module, with the coordinate of interpolation calculation data module; Process 804 is calculated the color correction coefficient according to preceding method, and the color of data module is proofreaied and correct; Process 805 is used the error correction of decoding FEC algorithm according to the parameter of the forward error correction coding algorithm that process 802 obtains to data.
The following discloses and a kind of data form computer is transferred to the method for the handheld mobile device with camera function, described method is used described colour matrix sign indicating number.As shown in Figure 9,901 is the data of transmitting terminal, and encoded software 902 codings obtain colour matrix sign indicating number 903, and described colour matrix sign indicating number 903 is sent to display 904 and shows.Planar array type color photoelectric image sensor 905 receives the light signal of display 904 emissions, the scioptics imaging obtains image 906, image 906 comprises the image of described colour matrix sign indicating number 903,906 decodings of 907 pairs of images of decoding software module obtain data 908, and data 908 equate with transmitting terminal data 901.The data sending terminal system forms by 901,902,903 and 904, and the Data Receiving end system is formed by 905,906,907 and 908.Utilize existing bar code or two-dimension code to substitute colour matrix sign indicating number of the present invention and also can realize described data-transformation facility, but these existing bar codes are not that its capacity and packing density all can not be given full play to the described using value that data form computer is transferred to the method for the handheld mobile device with camera function for the described method that data form computer is transferred to the handheld mobile device with camera function designs.The increasing built-in high-resolution planar array type of mobile phone color photoelectric image sensor, in existing mobile phone bar code is used, employed bar code is traditional monochromatic bar code mostly, thereby can not effectively utilize the color detection ability of planar array type color photoelectric image sensor.Generally speaking, mobile phone self can not provide illumination, and the camera lens that its planar array type color photoelectric image sensor uses do not have the microspur imaging function, has so further limited the practical value of mobile phone bar code application.There is not described restriction in technology disclosed in this invention, described colour matrix sign indicating number has made full use of the following characteristic of computer display: but self-luminous, high brightness and brightness evenly, the color representation ability is strong, dimension of picture can change as required, encoded content dynamic update of software etc., and above-mentioned characteristic is that conventional solid-state bar code carrier such as paper is not available.The present invention is under the prerequisite that does not increase hardware cost, and the mode of " obtaining with visible just the bat " has realized data form computer is transferred to the method for the handheld mobile device with camera function.

This color table is the color reference benchmark of the sign indicating number of colour matrix described in present embodiment coding and decoding.
Present embodiment prize the colour moment horizontal and vertical parity check code module for the square, line direction total number of modules and column direction total number of modules are odd number, the recognition feature of colour matrix sign indicating number is made up of 11 * 11 modules, described recognition feature is positioned at the positive center of colour matrix sign indicating number.4 kinds of colors are embodied as 301 black, 302 bluenesss, 303 redness, 304 magentas respectively among Fig. 3.
As shown in Figure 4, parameter memory block 402 has 40 modules, and parameter memory block module is only used black, the four kinds of colors of red, green, blue in the color table, so the data bit number of each module stores is log
24=2, the digital coding of every kind of color correspondence is color index value low 2 in the color table shown in the table 1.The total data capacity of 40 modules is 40 * 2=80 bit, wherein with the version coding of 4 bits to embodiment, the chromatic number coding that 2 bit log are used according to the memory block module, 12 bits are encoded to the line direction total number of modules, 12 bits are encoded to the column direction total number of modules, 20 bit log are according to the length coding of data that store the memory block, and the total length of the coding of these parameters is 50 bits.Utilization Reed-Solomon forward error correction coding algorithm is encoded once more to the coding of the parameter of described 50 bits, generates the error correction data of 30 bits.Reed-Solomon forward error correction coding technology is the error correction coding that generally uses in the data communication, also is technology well known to those skilled in the art.The encoded back of initial data produces error correction data, initial data and error correction data together are transferred to receiving terminal, receiving terminal is received the decoding algorithm of utilization and coding equity after the data, corrects the mistake that produces in the transmission course, or because wrongly too much can not correct whole mistakes and abandon the data of receiving.80 bits become 40 groups through the parameter after encoding by per two continuous bit one components, first parameter module of the upper left corner begins from Fig. 4, with the grouping bit value as color index, in the color table of table 1, get colors, give each parameter module painted in the direction of the clock successively, store parameter into the parameter memory block with this.
The following describes the execution mode of assist location feature.
Among Fig. 4, it is (0,0) that the ranks coordinate of center module in matrix of recognition feature demarcated, and is 8 module settings colors that connect the parameter memory block according to following mode:
Module (6 ,-6) is red;
Module (6,0) is a black;
Module (6,6) is green;
Module (0,6) is a black;
Module (6,6) is blue;
Module (6,0) is a black;
Module (6 ,-6) is a white;
Module (0 ,-6) is a black;
With these 8 modules is starting point, get following a kind of adjacent color of each module color in color table shown in the table 1 respectively, for the uncoloured assist location characteristic module that each module is adjacent painted, wherein, shown in the regulation table 1 in the color table white following a kind of adjacent color be black.For example module (6,-6) color is red, red following a kind of adjacent color in table 1 color table is green, the uncoloured auxiliary positioning module adjacent with module (6 ,-6) is module (7 ,-7), be module (7 then with green,-7) painted, this process that circulates all is colored until the module of all assist location features.
In order to make full use of the display area of computer display, the line direction total number of modules and the column direction total number of modules of the sign indicating number of colour matrix described in the present embodiment can be unequal.Usually, the width of computer display is greater than height, the column direction number of modules of corresponding described colour matrix sign indicating number is greater than the line direction number of modules, in this case, after arriving the border from the module of four jiaos of outward extending assist location features of recognition feature of described colour matrix sign indicating number, continue to extend forward according to mode shown in Figure 10, be that the assist location characteristic module in the upper left corner arrives the upper left corner module that extends to matrix behind the matrix top left, the assist location characteristic module in the lower left corner arrives the lower left corner module that extends to matrix behind the matrix bottom left, the assist location characteristic module in the upper right corner arrives the upper right corner module that extends to matrix behind the matrix top to the right, and the assist location characteristic module in the lower right corner arrives the last cell module that extends to matrix behind the matrix bottom to the right.
The data storage area of the sign indicating number of colour matrix described in the present embodiment uses whole 8 kinds of colors of listing in the color table, so each data module can be stored log
2The 8=3 Bit data.Regard data to be stored as Bit String, by every continuous 3 bits, one component group, 3 bits of last group less than are filled with bit 0.As color index, in table 1 color table, select a kind of color with each bit group, give a data module painted, be about to described bit group and stored the data module that is colored into selected color.
As shown in figure 10, the painted order of data module begins with the clockwise hand of spiral from the center to external radiation, promptly from data module 1001, advance in the direction of the clock, skip the assist location characteristic module that runs into, finish a circle after module 1002, first module 1003 from next circle begins the repetition said process then, so is circulated to module 1004.If the column direction total number of modules of described colour matrix sign indicating number is greater than the line direction total number of modules, be starting module then with module 1005, be scanned up to module 1006 with " it " font from right to left by the row master mode, jump to the data module 1007 of last cell then, continue " it " font scanning of front, be scanned up to the traversal that module 1010 is finished all data modules.
Introduce the capacity of the sign indicating number of colour matrix described in the present embodiment below.
The screen resolution of supposing the display color square matrix code is 1024 * 768, described each module of colour matrix sign indicating number is of a size of 3 * 3 pixels on screen, then the line number of colour matrix sign indicating number is 768/3=256, get odd number 255, the columns 1024/3 of colour matrix sign indicating number, round numbers 341, total number of modules of colour matrix sign indicating number is 255 * 341=86955, wherein the recognition feature number of modules is 11 * 11=121, parameter memory block number of modules is 40, assist location characteristic module number is 3 * (341-13)+(255-13)+8=1234, therefore data module adds up to 86955-121-40-1234=85560, the data capacity of every data module is 3 bits, and total capacity is 85560 * 3/8=32085 byte.With regard to the actual displayed ability of handheld mobile devices such as mobile phone, the capacity of 32085 bytes is enough to transmit the moderate image of a width of cloth quality.
