Embodiment
Fig. 4 is the synoptic diagram that designed a plurality of image indexes of one embodiment of the invention 10 are arranged the pattern that forms, and Fig. 5 is the enlarged diagram of an image index 10 wherein, to clearly demonstrate design of the present invention.As shown in Figure 5, image index 10 comprises a content-data portion 12 and a table header 14.According to present embodiment, content-data portion 12 comprises 9 little elementary areas that are made of 9 round dots 16; And described content-data portion 12 shared area region are divided into 9 state regions 18, thereby constitute one 3 * 3 planar state region arrays, make each state region 18 include a round dot 16.According to the design of present embodiment, can utilize the different putting positions of a round dot 16 in a state region 18, represent a numerical value in the pairing achievement data.Specifically, as shown in Figure 6, a state region 18 can be divided into four virtual regions, and round dot 16 selectivity place lower right, lower left, upper left side or upper right side virtual region, to represent four different place values 00,01,10 or 11 respectively.Therefore, the configuration relation of the round dot 16 shown in Fig. 5 content-data portion 12, the array of position that can be corresponding shown in Figure 7.When content-data portion 12 has 9 round dots 16 and be positioned in 9 state regions respectively, because of each described state region 18 is divided into four virtual regions, when each round dot 16 selectivity are arranged at one of them of four virtual regions, can make described content-data portion 12 have 4
9(=262144) plant combinations of states.So utilize the design of image index shown in Figure 5 10, can represent 262144 different numerical value in the pairing achievement data.Therefore, according to the design of present embodiment content-data portion 12, can be from described 262144 kinds of combinations of states taking-up 65536 kinds of combinations of states wherein, with literal 65536 affiliated coding sites in the corresponding ten thousand country code coding structures; All the other combinations of states then can keep as other purposes, for example, can provide the combinations of states as correspondence proving sign indicating number (checksum code) coding site.
On the other hand, because of image index 10 is made up of the little elementary area of a group,, table header 14 isolates two adjacent image indexes 10 to distinguish so need being set.As shown in Figure 8, four image indexes 10 all have identical content-data portion 12, just have identical achievement data content, so four image indexes 10 all are provided with an identical particular table head 14.So only need to seek out described specific table header 14, just can find out identical image index 10, and the interference of other image index 10 that can not be close to.Table header 14 comprises a plurality of little elementary area that is made of for example round dot 16 equally, and described table header 14 shared area region are divided into a plurality of state regions 18.With reference to figure 5, according to the design of present embodiment, each state region 18 of table header 14 includes a round dot of being located at state region 18 centers, so table header 14 has 7 round dots again; And on two adjacent edges circle,, the table header 14 L type that forms is distributed, and 4 * 4 square formations that entire image index 10 become be made of 16 round dots are arranged around having the content-data portion 12 of 9 round dots.As shown in Figure 5, the round dot putting position of table header 14 all is preset as the center of a state region, thereby can make the process of table header 14 of recognition image index more quick; It is different but the position of table header 14 one of them round dot 16 ' needs past specific direction skew with the position of other round dot 16.Like this when carrying out image recognition and read described image index 10, after optical devices (not shown) read body surface and obtain a magnified image, as long as identify the table header 14 of image index 10 earlier, just can be to described image index 10 orientations, with the combinations of states of accurate acquisition content-data portion 12.
In addition, by changing the putting position of table header 14 orbicular spots 16, can produce different each other different table head 14.Therefore, when the corresponding different numerical value of the combinations of states of each image index 10 by adjusting content-data portion 12, the image index 10 of corresponding two different numerical value can be differentiated both by different table header 14 respectively.As shown in Figure 9, two different different table header 14a and 14b of round dot 16 putting positions can be in order to differentiate neighbouring data portion 12a with different content and 12b.Perhaps, as shown in figure 10, two different different table header 14c and 14d of round dot 16 putting positions can be in order to differentiate adjacent data portion 12c with different content and the 12d in the left and right sides.
In addition, according to the design of present embodiment, table header 14 is formed on two adjacent edges circle of content-data portion 12, and defines the distribution range of the round dot 16 of described content-data portion 12.So, after utilizing optical devices to read image,, can utilize table header 14 to proofread and correct with the round dot arrangement in the accurate acquisition content-data portion 12 if image index 10 produces distortion when waiting distortions.
Below by the advantage of comparison diagram explanation the present invention with respect to existing design.
Figure 11 A is the simplified schematic diagram of existing design, the simplified schematic diagram that Figure 11 B designs for the present invention.Before explanation advantage of the present invention, at first define an effective information rate value:
E=(the round dot number of presentation video index content information)/(all round dot numbers).
Shown in Figure 11 A, in 5 * 5 round dot matrix block of an existing design, each information point 206 is all centered on by four lattice points 204; Therefore, an image index may be partitioned into a plurality of lattice points shown in the dotted line to 22, and each lattice point comprises a lattice point 204 and an information point 206 to 22; So the effective information rate value of existing design is 50%, and described value is can be with a fixed constant of round dot matrix block size variation.On the other hand, shown in Figure 11 B, with regard to the present invention's design of identical 5 * 5 round dot matrix block, deduction occupies the table header round dot on two borders, and its effective information rate value is (4 * 4)/(5 * 5)=64%.And according to design of the present invention, the effective information rate value is just high more when image index 10 is big more.One 10 * 10 round dot matrix block for example, its effective information rate value is (9 * 9)/(10 * 10)=81%.Hence one can see that, and effective information rate value of the present invention is obviously high than existing design, and can further improve with the image index increase.In other words, the present invention can utilize the identical quantity of information of less round dot number (lower round dot density) expression.
With regard to the design of an image index, should reduce the number of little elementary area according to the size of little elementary area and spacing each other as far as possible, image index is reduced the overall brightness influence of body surface.As previously mentioned, image index usually with the main information co-exist of body surface, therefore, when the density of round dot was high more, not only visual effect was poor more, and the existence of the easier perceptual image index of human eye and chance increase that image index and main information are obscured.Therefore, effective information rate value of the present invention is obviously high than existing design, so can utilize the identical quantity of information of less round dot number (lower round dot density) expression.The existence that can provide better visual effect and human eye relatively to be not easy the perceptual image index like this, and image index and main information are obscured.On the other hand, when image index forms in a limited body surface zone, under the prerequisite that the identical information amount is provided, shown in Figure 11 A, too high round dot distribution density causes the distance of two adjacent round dots too small, thereby generation comparatively significantly vision is disturbed, and perhaps increases easily to print difficulty and cause optical devices interpretation mistake or differentiate to be difficult for.Of the present inventionly then can not cause this problem than low-density design.
Figure 12 A and Figure 12 B are relatively the present invention and existing another simplified schematic diagram that designs.Shown in Figure 12 A, existing design in an image index because need to form a key point 202 at least, so four rectangular blocks that constituted together with four lattice points 204 around it and information point 206 need 13 round dots could constitute an image index at least.Yet, shown in Figure 12 B,, only need 4 round dots 16 can form an image index according to design of the present invention.Therefore, the present invention can constitute an image index with less round dot number, like this will be more flexible at the lip-deep set-up mode of different objects, and be not easy to cause too high round dot distribution density.
Figure 13 is another design example of image index 10 of the present invention.The distribution mode of round dot 16 on a state region 18 of content-data portion 12 do not limit, as shown in figure 13.When state region 18 is divided into four virtual regions, can divide into two groups of round dot distribution modes according to the distance of distance state regional center point P; The nearer round dot 16a of distance center point P is arranged at lower right, lower left, upper left side or upper right side virtual region, can represent four different place values 000,001,010 or 011 respectively; Distance center point P round dot 16b far away is arranged at lower right, lower left, upper left side or upper right side virtual region, can represent other four different place values 100,101,110 or 111 respectively.By this design, the distribution of round dot 16 on a state region 18 can produce 8 kinds of possible combinations of states.
Certainly, according to design of the present invention, one of them that only needs round dot 16 is placed a plurality of virtual regions is to represent different place values, and the virtual region quantity of being divided equally as for each described state region 18 does not limit.As shown in figure 14, also a state region 18 can be divided into eight virtual regions, each round dot 16 selectivity virtual region that is placed in one can produce 8 kinds of possible combinations of states.In other words, each round dot 16 of the present invention places the position of state region not limit, and only needs to look state region 18 and divides into several virtual regions and get final product.
In addition, little elementary area of image index 10 is not defined as the round dot 16 shown in aforementioned each embodiment, can be the point-like thing of for example other profile yet.Certainly, only needing to reach the purpose that identifies different conditions gets final product.Little elementary area does not limit a certain specific expression mode of utilizing, and for example, it is also passable to utilize short line segment 24 to represent as shown in figure 15.In addition, the little elementary area of image index 10 sum and arranging does not limit, and the state region square formation of image index 10 is not defined as and adopts an as broad as long square formation to arrange, and for example, the rectangle square formation that adopts length and width not wait as shown in figure 15 is also passable.
Figure 16 is the synoptic diagram of another design of the table header 14 in an image index 10.Table header 14 does not limit on the border that is distributed in an image index 10, can be arranged at the middle body of image index 10 as shown in figure 16 yet, and the effect that only needs can reach identification and locate an image index 10 gets final product.
The foregoing description only is used to illustrate the present invention, but not is used to limit the present invention.
