Embodiment
The multiple image indexes 10 of Fig. 4 designed by one embodiment of the invention arrange the schematic diagram of the pattern formed, and Fig. 5 is the enlarged diagram of a wherein image index 10, to clearly demonstrate design of the present invention.As shown in Figure 5, image index 10 comprises content-data portion 12 and a table header 14.According to the present embodiment, content-data portion 12 comprises 9 the micro-elementary areas be made up of 9 round dots 16; And 9 state regions 18 are divided in region shared by described content-data portion 12, thus form one 3 × 3 planar state region arrays, make each state region 18 include a round dot 16.According to the design of the present embodiment, the different putting positions of a round dot 16 in a state region 18 can be utilized, represent a numerical value in corresponding achievement data.Specifically, as shown in Figure 6, a state region 18 can be divided into four virtual regions, and round dot 16 selectivity is placed in 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 as shown in Fig. 5 content-data portion 12, may correspond to the array of the position shown in Fig. 7.When content-data portion 12 has 9 round dots 16 and is positioned over respectively in 9 state regions, because each described state region 18 is divided into four virtual regions, when each round dot 16 selectivity is arranged at four virtual regions one of them, described content-data portion 12 can be made to have 4
9(=262144) plant combinations of states.So utilize the design of the image index 10 shown in Fig. 5,262144 different numerical value in corresponding achievement data can be represented.Therefore, according to the design in the present embodiment content-data portion 12,65536 kinds of combinations of states wherein can be taken out from described 262144 kinds of combinations of states, with in corresponding ten thousand country code coding structures one literal belonging to 65536 coding sites; All the other combinations of states then can be retained as other purposes, such as, can be provided as the combinations of states of correspondence proving code (checksum code) coding site.
On the other hand, because image index 10 is made up of the micro-elementary area of a group, so need to arrange table header 14 to distinguish the adjacent image index of isolation two 10.As shown in Figure 8, four image indexes 10 all have identical content-data portion 12, namely have identical indexed data content, so four image indexes 10 all arrange an identical particular table head 14.So only need to find 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 the multiple micro-elementary area be made up of such as round dot 16 equally, and multiple state region 18 is divided in region shared by described table header 14.Referring again to Fig. 5, according to the design of the present embodiment, each state region 18 of table header 14 includes the round dot that is located at state region 18 center, so table header 14 has 7 round dots; And around the content-data portion 12 with 9 round dots on two adjacent boundaries, make table header 14 be formed as a L-type distribution, and whole image index 10 is made to become 4 × 4 square formations arrangements be made up of 16 round dots.As shown in Figure 5, the round dot putting position of table header 14 is all preset as the center of a state region, thus the process of the table header 14 of recognition image index can be made more quick; But the position of one of them round dot 16 ' of table header 14 needs toward a specific direction skew different from the position of other round dot 16.Like this when carrying out image recognition and reading described image index 10, after optical devices (not shown) reading body surface obtains a magnified image, as long as first identify the table header 14 of image index 10, just can be directed to described image index 10, accurately to capture the combinations of states in content-data portion 12.
In addition, by changing the putting position of table header 14 orbicular spot 16, different table header 14 different each other can be produced.Therefore, when each image index 10 is by numerical value that the combinations of states of Suitable content data portion 12 is corresponding different, both the image index 10 of corresponding two different numerical value is differentiated by different table header 14 respectively.As shown in Figure 9, the different table header 14a that two round dot 16 putting positions are different and 14b can in order to differentiate the neighbouring data portion 12a with different content and 12b.Or as shown in Figure 10, the different table header 14c that two round dot 16 putting positions are different and 14d can in order to differentiate the left and right adjacent data portion 12c with different content and 12d.
In addition, according to the design of the present embodiment, table header 14 is formed on two adjacent boundaries in content-data portion 12, and defines the distribution range of the round dot 16 in described content-data portion 12.So, after utilizing optical devices to read image, if when image index 10 produces the distortions such as distortion, table header 14 can be utilized to carry out the round dot arrangement correcting accurately to capture in content-data portion 12.
Below by way of comparison diagram, the advantage of the present invention relative to existing design is described.
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, first define an effective information rate value:
E=(representing the round dot number of image index content information)/(whole round dot number).
As shown in Figure 11 A, in 5 × 5 round dot matrix block of an existing design, each information point 206 all by four lattice points 204 around; Therefore, an image index may be partitioned into the multiple lattice points shown in 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 not with a fixed constant of round dot matrix block size variation.On the other hand, as 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, when image index 10 is larger, effective information rate value is higher.Such as one 10 × 10 round dot matrix block, its effective information rate value is (9 × 9)/(10 × 10)=81%.It can thus be appreciated that effective information rate value of the present invention is obviously high than existing design, and raising further can be increased with image index.In other words, the present invention can utilize less round dot number (lower round dot density) to represent identical quantity of information.
With regard to the design of an image index, according to the size of micro-elementary area and spacing each other, the number of micro-elementary area should be reduced as far as possible, the overall brightness impact of image index on body surface is reduced.As previously mentioned, image index usually and the main information of body surface coexist, therefore, when the density of round dot is higher, not only visual effect is poorer, and the existence of the easier perceptual image index of human eye and chance that image index and main information are obscured increases.Therefore, effective information rate value of the present invention is obviously high than existing design, so less round dot number (lower round dot density) can be utilized to represent identical quantity of information.Preferably visual effect and human eye compares the existence being not easy perceptual image index can be provided like this, and image index and main information can not be made to obscure.On the other hand, when image index is formed in a limited body surface region, under the prerequisite that identical information amount is provided, as shown in Figure 11 A, too high round dot distribution density causes the distance of two adjacent round dots too small, thus produce comparatively significantly vision interference, or easily increase printing difficulty and cause optical devices interpretation mistake or differentiate not easily.Comparatively low-density design of the present invention then can not cause this problem.
Figure 12 A and Figure 12 B is another simplified schematic diagram comparing the present invention and existing design.As illustrated in fig. 12, existing design because at least need formation key point 202, so four rectangular blocks formed together with four lattice points 204 around it and information point 206, at least needs 13 round dots could form an image index in an image index.But, as shown in Figure 12 B, according to design of the present invention, only need 4 round dots 16 can form an image index.Therefore, the less round dot number of the present invention can form an image index, and the set-up mode like this on different objects surface will be more flexible, and is 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 in content-data portion 12 does not limit, as shown in figure 13.When state region 18 is divided into four virtual regions, two groups of round dot distribution modes can be divided into 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 only needing round dot 16 to be placed in multiple virtual region is to represent different place value, and the virtual region quantity of dividing equally as 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, the position that each round dot 16 of the present invention is placed in state region does not limit, and only needs to divide into several virtual region depending on state region 18.
In addition, micro-elementary area of image index 10 is not defined as the round dot 16 shown in foregoing individual embodiments, can be the pointing object of such as other profile yet.Certainly, only need to reach the object identifying different conditions.Micro-elementary area does not limit and utilizes a certain specific representation, such as, utilizes short line segment 24 to represent passable as shown in figure 15 yet.In addition, micro-elementary area sum of image index 10 and arrangement do not limit, and the state region square formation of image index 10 is not defined as the as broad as long square formation arrangement of employing one, and such as, the rectangle square formation adopting length and width not wait as shown in figure 15 is also passable.
Figure 16 is another schematic diagram designed of the table header 14 in an image index 10.Table header 14 do not limit be distributed in an image index 10 border on, also can be arranged at the middle body of image index 10 as shown in figure 16, only need to reach and identify and locate the effect of an image index 10.
Above-described embodiment is to illustrate the invention and not to limit the present invention.
