For example, if round dot A is arranged at first region 112a of the first upper left, data area, can be in order to represent encoded radio 00; If round dot A is arranged at first region 112c of the first upper right, data area, can be in order to represent encoded radio 01; If round dot A is arranged at first region 112g of the first lower-left, data area, can be in order to represent encoded radio 10; If round dot A is arranged at first region 112i of the first bottom right, data area, can be in order to represent encoded radio 11.The putting position in above the first site and the corresponding relation of encoded radio are only one embodiment of the invention, and those skilled in the art can encode according to its actual demand.Accordingly, as shown in Figure 5, in data portion 100, utilize the first site different putting position in the first block 110, can represent different encoded radio combinations, different encoded radio combinations can represent different pointer datas.In like manner, if in a data area, while being equipped with site in different regions, position, making the permutation and combination of encoded radio more complicated, and can represent more data combination.
Get back to Fig. 5, next the composition structure of labeling section 200 is described.As shown in Figure 5, labeling section 200 is divided into a plurality of the second blocks 210, in the present embodiment, by the second block 210, according to the difference of position, give different numberings, therefore labeling section 200 comprises seven second block 210A～210G, and those second blocks 210A～210G presents a L-type and distributes, and the labeling section 200 that is L-type and two of data portion 100 adjacent border adjacency.Therefore, the first block 110 and second block 210A～210G are arranged in 4 * 4 block array.Each second block 210A～210G also can divide into a plurality of second regions of arranging with (P * Q) array way, and wherein P, Q are all the integer that is more than or equal to 3.P, Q all equal 3 in the present embodiment, so each second block 210A～210G is divided into a plurality of seconds region, and arrange with 3 * 3 array way in these second regions.
Fig. 8 is the enlarged diagram of the second block 210D in Fig. 5.Please refer to Fig. 8, if give different numbering 212a～212i by second region according to the difference of position again, five present the second region 212b that cruciform is arranged, 212d, and 212e, 212f, 212h forms the second marked region 214.Each second block 210A～210G all only has second site, and in the present embodiment, the second site of second block 210A～210G must be arranged at the region, position within the second marked region 214.That is to say, the second site can only be arranged at five second region 212b, 212d, 212e, 212f, 212h one of them.As shown in Figure 8, the second site is for example round dot B, and round dot B is arranged at the second region 212e within the second marked region 214.Again, second region 212e is the centre of the second marked region 214 that is cruciform arrangement.
Please refer to Fig. 4, labeling section 200 can be in order to separate two adjacent some codings 10, so in carrying out image recognition (pattern/image recognition), read this some coding at 10 o'clock, when reading body surface, optical devices obtain after an enlarged image, as long as first identify a labeling section 200 for coding 10, except can accurately identify first site of each block of data portion 100 set be that region, position of the first data area, can also further define putting in order of block in data portion 100.
Moreover, by changing the putting position in the second site in labeling section 200, can produce different each other different labeling section 200.Please refer to Fig. 5, the second site of the second block 210D is arranged at the crossover sites of the second marked region 214.Wherein, be positioned at the second block 210A of same row, 210B, each second site of 210C is along first direction, to depart from the crossover sites of the second corresponding marked region 214.First direction is for example the X-direction of two-dimensional direct angle coordinate system.On the other hand, be positioned at the second block 210E of same a line, 210F, each second site of 210G is along second direction, to depart from the crossover sites of the second corresponding marked region 214.Second direction is for example the Y direction of two-dimensional direct angle coordinate system.This means, the vertical in fact second direction of first direction.
Fig. 9 illustrates another design diagram into labeling section 200 in a coding 10.Please refer to Fig. 9, be positioned at the second block 210A of same row, 210B, each second site in 210C is the crossover sites that is arranged at the second corresponding marked region.And be positioned at the second block 210E of same a line, and 210F, each second site of 210G is the crossover sites that departs from the second corresponding marked region.Thus, labeling section 200 can help the coded message of accurate acquisition data portion 100.
Figure 10 illustrates as another design diagram of coding 10.Point coding 10 is comprised of a data portion 100 and a labeling section 200 equally.9 the first blocks 110 are divided in the shared region of data portion 100.7 the second blocks 210 are divided in the shared region of labeling section 200.Different from previous embodiment, the first block 110 is also divided into a plurality of first region 112, and arrange with 5 * 5 array way in these first region 112.
Figure 11 A is the enlarged diagram of one of them the first block 110 in Fig. 9.Please refer to Figure 11 A, if give different numberings by each first region 112 in the first block 110 according to the difference of position, by upper left to bottom right, be sequentially first region 112a, 112b ..., 112y.Wherein, be arranged in criss-cross first region 112c, 112h, 112k, 1121,112m, 112n, 112o, 112r, 112w forms the first marked region 114.From Figure 11 A obviously, the first marked region 114 is divided into mutually not four data areas of adjacency by the first block 110, and wherein the first data area is 112a, 112b, 112f, 112g; The second data area is 112d, 112e, 112i, 112j; The rest may be inferred in all the other two data areas.
Be similar to previous embodiment, the first block 110 has one first site, and the first site must be arranged at the region outside the first marked region 114.For example, first site of the present embodiment is round dot A, can be arranged at four data areas as shown in Figure 11 A one of them.If round dot A is arranged at the first data area, can be in order to represent encoded radio 00; If round dot A is arranged at the second data area, can be in order to represent encoded radio 01; If round dot A is arranged at the 3rd data area, can be in order to represent encoded radio 10; If round dot A is arranged at the 4th data area, can be in order to represent encoded radio 11.
Yet each data area all consists of first region of similar number, therefore, round dot A, except selecting to be arranged at four data areas one of them, also can select to be arranged in one of them first region of this data area.As shown in Figure 11 B, Figure 11 B illustrates and is arranged in first region 112a～112y corresponding respectively encoded radio schematic diagram for round dot A.In other words, if the first block 110 is all encoded with four positions as shown in Figure 11 B, the data portion shown in Figure 10 100 has the combination of 169 kinds.So utilize some coding 10 designs shown in Figure 10, can represent 169 different numerical value in corresponding pointer data.
Based on above-mentioned, by the first block 110 being divided into first region of different numbers, can increase deviser and utilize space in design data portion 100 with the elasticity of pointer data.On the other hand, the second block 210 of the labeling section 200 shown in Figure 10 has identical size with the first block 110, and the second marked region arrangement mode in the second block 210 is same as the first marked region arrangement mode in the first block 110.At this, should be noted, the second site in the second block 210 is all arranged at the second marked region with in one of them interior second region.
Embodiment shown in aforementioned, its data portion 100 is all identical design with block and the marked region of labeling section 200.So the present invention also can do different design variation from the criss-cross marked region of labeling section 200 for data portion 100, as shown in Figure 12 A and Figure 12 B.Figure 12 A illustrates as another design drawing of the first block 110 of coding 10.Please refer to Figure 12 A, the first block 110 is divided into region, 7 * 7 positions and is arranged and to form with array way, wherein, the first marked region 114A by wherein row at this first block 110 center and wherein a line formed.With the embodiment shown in Figure 11 A in comparison, because the first block 110 of Figure 12 A is divided into more first region, so the area in each first region is less than first region shown in Figure 11 A.In other words, the width W of criss-cross the first marked region 114A is less than the width of the first marked region 114 shown in Figure 11 A.
Figure 12 B illustrates as an another design drawing for the first block 110 of coding 10.Please refer to Figure 12 B, the first block 110 is divided into equally 7 * 7 first regions and is arranged and form with array way.Yet wherein criss-cross the first marked region 114B is comprised of adjacent three row and adjacent three row at this first block 110 center.This means, the minimum widith W ' of the cruciform first marked region 114B of the present embodiment is 3 times of width W in first region.Accordingly, the present invention is the minimum widith in limit markers region not, as long as the minimum widith of marked region is the integral multiple of the width in region, position.
In addition, it should be noted that, the more, the area in each region is less for the position number of regions of distinguishing in each block, therefore the position that site can be put and area are also not identical, so user can consider that site designs the number region distinguished and the minimum widith of marked region.Moreover the block of labeling section 200 and marked region can be different designs from block and the marked region of data portion 100.For instance, if each block of the data portion 100 of point code 10 and marked region thereof are the design of Figure 12 A; And in same point coding 10, the block of its labeling section 200 and marked region thereof can be the design of Figure 12 B.
Above-mentioned in an embodiment of coding 10, no matter be the first or second block, its shape that forms marked region is all the cruciform that is positioned at block central authorities, yet the present invention is not limited to this.As shown in Figure 13 A and Figure 13 B, Figure 13 A illustrates as an another design drawing for the first or second block of coding 10.Figure 13 B illustrates as a design drawing again for the first or second block of coding 10.And set position is also not limited to the central authorities of block.
Please refer to Figure 13 A, this block can be the first block of the data content that forms some coding 10, also can be the second block of the tag content that forms some coding 10.This block is formed by the position area arrangement of 5 * 5 arrays, and wherein, marked region 300A is " one " font, the central region, adjacent 5 positions that it comprises this block.If this block belong to data content one of them, the site putting position in this block must be arranged at the region beyond marked region 300A; On the contrary, if this block belong to tag content one of them, the site putting position in this block must be arranged at marked region 300A with interior region.
Please refer to Figure 13 B, be similar to Figure 13 A, its difference is that the separated region 300B of the block of Figure 13 B is " 1 " font.Similarly, if this block belong to data content one of them, the site putting position in this block must be arranged at the region beyond marked region 300B; On the contrary, if this block belong to tag content one of them, the site putting position in this block must be arranged at marked region 300B with interior region.
The point coding 10 that the various embodiments described above illustrate and block thereof are only that example is implemented in a kind of selection; should not limit the scope of the invention; the arrangement mode that forms the block of tag content and the block of composition data content might not be limited to symmetrical square; it can be arranged in the block array of (A * B), and wherein A, B are greater than 1 positive integer.In addition, the arrangement mode that forms the block of tag content is not limited with L shaped yet, its can be wherein row in a coding 10 and wherein a line form.
From another viewpoint, Figure 14 A is a kind of schematic diagram of putting coding according to the present invention's one alternate embodiment.Figure 14 B is the enlarged diagram of one of them virtual block in Figure 14 A.Please coordinate with reference to Figure 14 A and Figure 14 B, some coding 14 comprises a plurality of virtual block 140A～104N and a plurality of site d.Wherein, virtual block 140A～104N forms 4 * 4 matrix.Each virtual block 140A～104N is all divided into a central marks portion (central label part) and region, position, four corners (corner bit zone).In the present embodiment, the central marks portion in each virtual block 140A～104N and the separation mode in region, position, four corners are all identical with arrangement mode, but are not limited to this.
