Embodiment
As depicted in figs. 1 and 2, the present invention relates to a kind of color graphics code recognition method, it comprises step
A), color graphics coding, obtain the pictorial information of color graphics coding and go out more that details are sent to user terminal through the service end index; This process is mainly obtained this color graphics coding through take the mode of obtaining picture at the handset starting camera, and utilizes wireless network to be sent to far-end server through the cellular service end.Information flow-rate when sending in order to reduce; Need to use the software that is installed on the mobile phone that above-mentioned picture is carried out the equal proportion compression; Generally can the length of side of picture be compressed in about 200 pixels and get final product; In the process that above-mentioned picture is uploaded, upload user's customer authentication information such as name in an account book and password simultaneously.
B), user rs authentication, far-end server checking client validity effectively then receives picture and continues step, otherwise end step; Far-end server is when carrying out above-mentioned customer authentication, and is main through transferring the information such as username and password that are stored in the server, and the username and password information of uploading with picture is verified.
C), whether there is the edge; The color distortion of the color block at the angle through color graphics coding and the eliminating of color block length of side ratio factor are also judged the edge of picture active graphical; And attempt extracting sign indicating number angular coordinate---angular coordinate comprises at least 3; Going together the most frequently used is 4, and four angular coordinates constitute a square color graphics coding region.If can't obtain then end step of angular coordinate, can obtain then and continue, can't obtain angular coordinate generally speaking and mainly cause owing to color block exceeds the permissible error scope; The effect of discerning above-mentioned edge mainly is that effective color graphics is encoded by separating in the pictures taken, avoids other achromaticity encoding of graphs parts in the picture, judges into the color graphics coding by accident, and carries out further wrong identification.Carry out the figure direction of color graphics coding then and confirm step; Promptly seek the figure direction identification block that is arranged on color graphics coding non-central location; For the ease of accurate recognition, this figure direction identification block employing and other all colours piece colors are various colors all, as shown in Figure 2; The black of the second from left position, top is figure direction identification block.Figure direction identification block is arranged on the non-central location of color graphics coding, and the closer to the color graphics encoder edge, its identification accuracy is good more.If be arranged on the center of color graphics coding certainly, then can lose figure direction recognition capability.
Because the first step that is retrieved as the color graphics code identification of angular coordinate; Whether its identification is accurate; Decisive role is played in identification afterwards; Therefore in order better to guarantee the accuracy of angular coordinate identification, the angular coordinate color block is the color lump different with other color block colors, like the green block among Fig. 3.In order to improve the accuracy of angular coordinate identification, the identification of angular coordinate is wanted and can repeatedly be checked.Just in the angular coordinate color block; The affirmation ring of other colors just is set around the angular coordinate identification block; Like the redness 2 and blue 3 parts that are centered around green block 1 both sides among Fig. 3, its concrete steps are: at first discern the angular coordinate identification block, promptly be positioned at the green block 1 in the color block centre of corner location among Fig. 2; Then continue identification if meet, otherwise finish identification.Confirm angular coordinate identification block color meet preset color after; Be predisposed to green 1 in the present embodiment; Then seek respectively redness 3 around its two limits around the above-mentioned green 1 angular coordinate identification block and confirm that ring confirms ring with blue 2; But confirm that ring all meets after the color and position that presets, promptly finally confirm angular coordinate, otherwise finish identification step for above-mentioned two.
D), whether there is color information; The factor of the length of sides such as the angular coordinate through color graphics coding and the number of color graphics encoded colors piece and color block; Set up the mode of rectangular coordinate system by the connecting line on five equilibrium limit; Obtain the coordinate of all colours piece in the color graphics coding, then according to coordinate figure obtain the coordinate figure place each color block figure and extract the color value of this color block, if the color block aberration overruns; End step then, otherwise obtain the color value continued step of all color lumps; As shown in Figure 3, after obtaining the angular coordinate identification block, four above-mentioned angular coordinate identification blocks are taken turns doing the central point connecting line, constitute a quadrilateral thus, this quadrilateral area is effective color graphics coding region.This is the color block quantity that can analyze on every limit; And get the corresponding limit of some five equilibrium of respective numbers according to color block quantity; And correspondence is done line; Such two groups of lines will intersect to form the intersection point identical with color block quantity each other, and its these angles are positioned at the center of each color block, and these intersection points are set to the color that each color block is extracted in the color taking point.
E), information transforms, and obtains the string number string all colours piece permutation and combination and according to color that has defined and digital correspondence table coupling.Here need to prove the digital system of the number of colors decision numeric string employing of color block, when promptly color was n, numeric string was and adopts the setting of n system.When the statistics number of colours, to deduct the color of figure direction identification block.Like the figure direction identification block of deduction black among Fig. 3, the number of colours of confirming color block is 3, and is promptly red, blue, green.According to this resolution rules, can each color block in the figure be resolved to the string number symbol of 3 systems.
F), information analysis, give client through passback after finding step gained numeric string pairing information data in the numeric string table of comparisons, simultaneously the relevant information and the user side information of recording operation; When reality is used, promptly above-mentioned information data is sent in the mobile phone of client by far-end server.
G), data readback, client shows the information data (for example can comprise network address, literal, picture, audio frequency, video etc.) of corresponding passback.
Of Fig. 1; In carrying out angular coordinate identification and color block identifying; Need to use the color block permissible error scope control module in the far-end server that above-mentioned color block error is controlled; When the color block error exceeds allowed band, finish proving program automatically, and this can't be verified perhaps and can't identified information feed back to the user.
As shown in Figure 3, be the coding of the color graphics among the present invention synoptic diagram.
Color graphics coding in this figure; What adopt is five to take advantage of five array arrangement mode; White edge at first scheming; Be the fringe region of coloud coding, the main effect in this zone is by extracting in the numerous and diverse picture of color, with the validity of the color graphics coding that guarantees to get access to the color graphics coding; Be positioned at four color block of corner location in this figure; Be exactly the angular coordinate identification block, this angular coordinate identification block is made up of two parts, and what be positioned at the center is the center identification piece that really is used for confirming angular coordinate; The i.e. green block 1 at these four color block centers; Then setting is around the affirmation ring of this identification block around the center identification piece, and promptly the red piece 2 and blue piece 3 in these four color block outsides confirm that the effects that encircle are similar to fringe region above-mentioned for above-mentioned two; It is variegated promptly to get rid of interference, guarantees angular coordinate affirmation accuracy.Being positioned at the black color piece of the second from left position, color block array top, is picture direction identification block, and its effect mainly is to proofread and correct the picture direction, avoids owing to the picture poor direction really causes color graphics code identification mistake.This picture direction identification block generally speaking; Be preferably disposed on the outermost of color block array; Improving its correction for direction ability, but to guarantee that picture direction identification block is positioned at the array center position, can cause picture direction identification block forfeiture picture correction for direction ability like this.After getting rid of above-mentioned four angular coordinate identification blocks and figure direction identification block, all the other color block in the remaining color block array are color graphics encoded colors piece.Can know that in this figure what color coding adopted is that middle color is red, blue, green.So can constitute a ternary numeric string by this group color graphics coding.
