Description

Technical Field

[0001] This invention relates to the field of image recognition technology, and in particular to a design method for recognizing coded image structures. Background Technology

[0002] For example, U.S. Patent 5,852,434 describes a position-encoded pattern that encodes the XY coordinates of multiple locations on a write surface. The position-encoded pattern enables a user to electronically record graphic information generated on the write surface by continuously reading the position-encoded pattern.

[0003] US Patent 5,852,434 provides three examples of constructing position-coded patterns. In the first example, the pattern consists of symbols, each composed of three concentric circles. The outer circle represents the X coordinate, and the middle circle represents the Y coordinate. Furthermore, the two outer circles are divided into 16 sections, each representing a different number depending on whether these sections are filled. This means that each pair of X and Y coordinates is encoded using complex symbols with a specific appearance;

[0004] In the second example, the coordinates of each point on the surface are given by a barcode, with the barcode for the X coordinate shown above the barcode for the Y coordinate;

[0005] A grid pattern, which can be used to encode X and Y coordinates, is presented as a third example. However, it is not explained how the grid pattern is constructed or how it is converted into coordinates;

[0006] The problem with known patterns is that they are composed of complex symbols, and the smaller these symbols are made, the more difficult it is to manufacture the writing surface on which the pattern is drawn, and the greater the risk of mispositioning. Patent publication number CN101064013B, entitled "A Data Output and Input Method Using Image Structures," describes the formation of at least one image structure corresponding to one index data on the surface of an object. The image index structure includes a content data section and a positioning section. The content data section includes multiple first micro-image units, and the area occupied by the content data section is divided into multiple first state regions. Each first state region is provided with one first micro-image unit, and the first micro-image units are selectively located in the equally divided first state regions. One of the multiple virtual regions formed; the positioning unit includes multiple second micro-image units and the area occupied by the positioning unit is divided into multiple second state regions; each second state region is provided with a second micro-image unit, the first state region and the second state region constitute a two-dimensional state region array, the second state region constitutes the outermost row and the outermost column of the two-dimensional state region array, a certain second micro-image unit is offset from the center of its respective second state region in a specific direction, and the remaining second micro-image units are all set at the center position of their respective second state regions, the setting position of each second micro-image unit in each second state region provides header information for identifying the image structure;

[0007] The known problem is that the micro-image unit of the positioning section is separated from the data section, which results in some line segments that can be clearly seen after printing. In addition, the error tolerance of the information in the data section is not high when it is checked by CheckSun.

[0008] The known problem is that the micro-image unit of the positioning section is separated from the data section, which results in some line segments that can be clearly seen after printing. In addition, the error tolerance of the data section is not high when the information is checked by CheckSun.

[0009] Therefore, improving the success rate of optical device interpretation or resolution, as well as the aesthetics of printing, remains one of the problems to be solved by those skilled in the art. Summary of the Invention

[0057] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other; and the term "and / or" includes both "and" and "or" possible embodiments.

[0058] This invention provides a design method for recognizing coded image structures.

[0059] Figure 1 This is a schematic diagram of a pattern formed by arranging multiple image structures 10 according to an embodiment of the present invention. Figure 2 This is an enlarged schematic diagram of one of the image structures 10 to clearly illustrate the design of the present invention. For example... Figure 2 As shown, the image structure 10 includes a content data section 12 and a positioning section 14. According to this embodiment, the content data section 12 includes 15 micro-image units composed of 15 information points 16; and the area occupied by the content data section 12 is divided into 9 first state regions 18, of which 6 are disposed in 6 second state regions. The first micro-image units are selectively disposed in the first, second, third, or fourth virtual regions, thereby forming a 3×3 planar two-dimensional state region array, so that each state region 18 includes one information point 16. According to the design of this embodiment, the different placement positions of an information point 16 in a state region 18 can be used to represent a value in the corresponding image structure data. Specifically, as... Figure 3 As shown, a state region 18 can be divided into four virtual regions. Information points 16 are selectively placed in the lower right, lower left, upper left, or upper right virtual regions to represent four different bit values: 00, 01, 10, or 11, respectively. Therefore, as... Figure 2 The configuration relationship of the information points 16 shown in the content data unit 12 can correspond to Figure 4 The array of bits shown. When the content data unit 12 has 15 information points 16 and is placed in 15 state regions, since each state region 18 is divided into four virtual regions, when each information point 16 is selectively set in one of the four virtual regions, the content data unit 12 can have 4^15 (=1073741824) state combinations. Therefore, using Figure 2The design of the image structure 10 shown can represent 1,073,741,824 different values ​​in the corresponding image structure data. Therefore, according to the design of the content data unit 12 in this embodiment, 65,536 state combinations can be extracted from the 107,374,1824 state combinations to correspond to the 65,536 encoding positions of a character in the Unicode encoding structure; the remaining state combinations can be reserved for other uses, for example, they can be provided as state combinations corresponding to checksum code encoding positions; the information points 16 are divided into content data information points and positioning information points, both of which are distributed within the state area 18.

[0060] On the other hand, since the image structure 10 is composed of a group of micro-image units, a positioning part 14 is needed to distinguish and isolate two adjacent image structures 10. For example... Figure 5 As shown, all four image structures 10 have the same content data section 12, that is, they have the same image structure data content. Therefore, all four image structures 10 are provided with the same specific positioning section 14. Thus, by simply finding the specific positioning section 14, the same image structure 10 can be identified without interference from neighboring image structures 10. The positioning section 14 also includes multiple micro-image units composed of, for example, information points 16, and the area occupied by the positioning section 14 is divided into multiple state regions 18. (See also...) Figure 2 According to the design of this embodiment, each state region 18 of the positioning unit 14 includes a positioning information point located in the state region 18. The positioning information point includes a positioning origin 20 and an auxiliary positioning point 21. The positioning origin 20 is located at the center of the second state region 18. The auxiliary positioning point 21 extends at equal intervals along one row and one column of the two-dimensional state region array formed by the second state region 18 where the positioning origin 20 is located, with the positioning origin 20 as the starting point. Therefore, the positioning unit 14 has 5 information points. And around the content data unit 12 with 15 information points on two adjacent boundaries, the positioning unit 14 is formed in an L-shaped distribution, and the entire image structure 10 is arranged in a 4×4 square matrix composed of 20 information points. Figure 2 As shown, the positioning origin 20 of the positioning unit 14 is located at the center of the second state region 18; the auxiliary positioning points 21 of the positioning unit 14 extend at equal intervals along one row and one column of the two-dimensional state region array formed by the second state region 18 where the positioning origin 20 is located, thereby making the process of recognizing the image structure of the positioning unit 14 faster. In this way, when performing image recognition to read the image structure 10, after the optical device (not shown) reads the object surface to obtain a magnified image, as long as the positioning unit 14 of the image structure 10 is identified first, the image structure 10 can be oriented to accurately capture the state combination of the content data unit 12.

[0061] like Figure 17 , 18 As shown, the second micro-image unit is composed of positioning information points, including a positioning origin 20 and auxiliary positioning points 21. The positioning origin 20 is located at or near the center of the second state region 18. The auxiliary positioning points 21 extend at equal intervals along one row and one column of the two-dimensional state region array formed by the second state region 18 where the positioning origin 20 is located, with the positioning origin 20 as the starting point. The auxiliary positioning points 21 have a center point 23, and the center points 20 of the auxiliary positioning points 21 intersect to form a virtual cross intersection 22. With the virtual cross intersection 22 as the center, and in conjunction with the row and column where the auxiliary positioning points 21 are located, a third state region 18' is formed. Some of the first micro-image units are selectively located in one of the multiple virtual regions formed by equally dividing the third state region 18'.

[0062] For example, in a 5×5 planar two-dimensional state region array, the positioning unit 14 has 5 second micro-image units; the content data unit has 17 first micro-image units, of which 9 first micro-image units are disposed in 9 first state regions 18, 6 first micro-image units are disposed in 6 second state regions 18, and 2 first micro-image units are disposed in 2 third state regions 18. The first micro-image units are selectively disposed in the first, second, third, or fourth virtual regions, so that the content data unit 12 has 1,717,986,9184 state combinations.

[0063] Furthermore, the positioning unit 14 has 5 positioning information points; the content data unit 12 has 17 content data information points, of which 9 content data information points are set in 9 first state areas, and 6 content data information points are set in 6 second state areas 18. The content data information points are selectively set in the first, second, third, or fourth virtual areas, so that the content data unit has 1,717,986,9184 state combinations.

[0064] Furthermore, according to the design of this embodiment, the positioning part 14 is formed on two adjacent boundaries of the content data part 12, and defines the distribution range of the information points 16 of the content data part 12. Therefore, after reading the image using an optical device, if the image structure 10 produces distortions such as deformation, the positioning part 14 can be used for correction to accurately capture the arrangement of information points in the content data part 12.

[0065] The advantages of this invention over existing designs are illustrated below using comparative figures.

[0066] Figure 10 This is a simplified schematic diagram of the existing design. Figure 11This is a simplified schematic diagram of the present invention. Before explaining the advantages of the present invention, an effective information ratio value is first defined: E = (number of information points representing the structural content information of the image) / (total number of information points).

[0067] like Figure 10 As shown, in a 5×5 information point matrix block of a conventional design, each information point 206 is surrounded by four grid points 204; therefore, an image structure can be divided into multiple grid point pairs 22 as shown by the dashed lines, each grid point pair 22 including one grid point 204 and one information point 206; therefore, the effective information ratio of the conventional design is 50%, and this value is a fixed constant that does not change with the size of the information point matrix block. On the other hand, as Figure 11 As shown, in the design of the present invention for a 5×5 information point matrix block, after deducting the positioning information points occupying two boundaries and adding six positioning information points located on the two boundaries, the effective information ratio is (7×7) / (5×5) = 196%. Furthermore, according to the design of the present invention, the effective information ratio can reach its maximum within a certain range of image structure 10. For example, in a 6×6 information point matrix block, the effective information ratio is (7×7) / (6×6) = 136%. Therefore, it can be seen that the effective information ratio of the present invention is significantly higher than that of existing designs, and the effective information ratio can reach its maximum within a certain range of image structure, exceeding the effective information ratio values ​​of many existing image structures.

[0068] Regarding the design of an image structure, the number of micro-image units should be minimized based on their size and spacing to reduce the overall brightness of the object's surface. As mentioned earlier, the image structure typically coexists with the main information of the object's surface. Therefore, the higher the density of information points, not only is the visual effect worse, but the human eye is also more likely to perceive the presence of the image structure, increasing the chance of confusion between the image structure and the main information. Therefore, the effective information ratio of this invention is significantly higher than existing designs, allowing the same amount of information to be represented with fewer information points (lower information point density). This provides better visual effects, and the human eye is less likely to perceive the presence of the image structure, preventing confusion between the image structure and the main information, and avoiding information loss (during acquisition). On the other hand, when the image structure is formed in a limited area of ​​the object's surface, under the premise of providing the same amount of information, such as... Figure 10 As shown, excessively high information point density leads to insufficient distance between adjacent information points, resulting in significant visual interference, increased printing difficulty, and errors in optical device interpretation or resolution. The lower density design of this invention avoids this problem.

[0069] Figure 12 and Figure 13Another schematic diagram is provided for comparison between the present invention and existing designs. (See attached diagram.) Figure 12 As shown, in the existing design, because at least one keypoint 202 needs to be formed in an image structure, along with the four rectangular blocks formed by the four surrounding grid points 204 and the information points 206, at least 13 information points are required to form an image structure. However, as Figure 13 As shown, according to the design of the present invention, only 6 information points 16 are needed to form an image structure. Therefore, the present invention can construct an image structure with a smaller number of information points, which makes the setting method more flexible on different object surfaces, and is less likely to cause excessively high information point distribution density, and will not cause information loss of information points (when being collected) due to excessively sparse information point distribution.

[0070] Figure 14 This is another design example of the image structure 10 of the present invention. The distribution of information points 16 on a state region 18 of the content data section 12 is not limited, such as... Figure 14 As shown, when the state region 18 is divided into four virtual regions, the information points can be distributed in two groups based on their distance from the center point P. Information points 16a, closer to the center point P, are placed in the lower right, lower left, upper left, or upper right virtual regions, representing four different bit values: 000, 001, 010, or 011, respectively. Information points 16b, farther from the center point P, are placed in the lower right, lower left, upper left, or upper right virtual regions, representing another four different bit values: 100, 101, 110, or 111, respectively. Through this design, the distribution of information points 16 in a state region 18 can generate eight possible state combinations.

[0071] Of course, according to the design of the present invention, it is only necessary to place the information point 16 in one of the multiple virtual regions to represent different bit values, and the number of virtual regions equally divided by each of the state regions 18 is not limited. Figure 15 As shown, a state region 18 can also be divided into eight virtual regions, and each information point 16 can be selectively placed in one of these virtual regions to generate eight possible state combinations. In other words, the position of each information point 16 in the state region is not limited, it only needs to be determined how many virtual regions the state region 18 is divided into.

[0072] Figure 15 This is another design example of the image structure 10 of the present invention. The distribution of information points 16 in a state region 18 of the content data section 12 is not limited, such as... Figure 16As shown, when the state region 18 is divided into four virtual regions, the information points can be distributed in two groups based on their distance from the center point P. Information points 16c, closer to the center point P, are placed in the lower right, lower left, upper left, or upper right virtual regions, representing four different bit values: 000, 001, 010, or 011, respectively. Information points 16d, farther from the center point P, are placed in the lower right, lower left, upper left, or upper right virtual regions, representing another four different bit values: 100, 101, 110, or 111, respectively. Through this design, the distribution of information points 16 on a state region 18 can generate eight possible state combinations.

[0073] on the other hand, Figure 16 The image structure 10 of the present invention records information points 16 to form a first micro-image unit, and is composed of at least three information points 16'; the distribution of the information points 16 on a state region 18 of the content data section 12 is not limited, such as Figure 16 As shown. When the state region 18 is divided into four virtual regions, the information points can be distributed in two groups based on their distance from the center point P of the state region. The information point 16e, which is closer to the center point P, is set in the lower right, lower left, upper left, or upper right virtual regions, and can represent four different bit values ​​000, 001, 010, or 011, respectively. The information point 16f, which is farther from the center point P, is set in the lower right, lower left, upper left, or upper right virtual regions, and can represent another four different bit values ​​100, 101, 110, or 111, respectively. Through this design, the distribution of information point 16 in a state region 18 can generate eight possible state combinations.

[0074] Furthermore, the micro-image units of image structure 10 are not limited to the information points 16 shown in the aforementioned embodiments, but can also be point-like objects of other shapes, for example. Of course, it is only necessary to achieve the purpose of recognizing different states. The micro-image units are not limited to using a specific representation method, such as... Figure 4 , Figure 7 As shown, the image structure 10 of the present invention records information points 16, which are positioning origins and auxiliary positioning points. The positioning origin is formed by at least three information points 16” in an L-shape located in the state region, and the auxiliary positioning point is formed by at least two information points 16” in a line shape. The first micro-image unit of the virtual region is selectively placed near the center of the state region 18, wherein the positioning origin of the second micro-image unit occupies a state region 18 and is placed near the center of the state region 18. The second micro-image unit does not overlap with the first micro-image unit. Figure 6The image structure 10 of the present invention records information points 16 to form a first micro-image unit, and is composed of at least three information points 16'; the distribution of the information points 16 on a state region 18 of the content data section 12 is not limited, such as Figure 16 As shown. When the state region 18 is divided into four virtual regions, the information points can be distributed in two groups based on their distance from the center point P of the state region. Information points 16e, which are closer to the center point P, are placed in the lower right, lower left, upper left, or upper right virtual regions, representing four different bit values: 000, 001, 010, or 011, respectively. Information points 16f, which are farther from the center point P, are placed in the lower right, lower left, upper left, or upper right virtual regions, representing another four different bit values: 100, 101, 110, or 111, respectively. Through this design, the distribution of information points 16 in a state region 18 can generate eight possible state combinations, thus producing different state combinations.
