1 illustrates a code generation and recognition system based on scan distance including a code generation apparatus 100 and a terminal apparatus 200 according to an embodiment.

The code generation device 100 may be any type of device capable of communicating with a computer (e.g., a desktop, a laptop, a tablet, etc.), a media computing platform (e.g., a cable, a satellite set top box, a digital video recorder), a handheld computing device , Email client, etc.), any form of mobile phone, or any other type of computing or communication platform, but the invention is not so limited.

The code generation apparatus 100 generates a code including a figure 12 that is moved to a predetermined distance or less in an arbitrary direction from a lattice point 11 included in the lattice pattern 10, 19), and the specific information is matched to the cell (19). A description of the sequence in which the code generating apparatus 100 generates a code will be described later.

The terminal device 200 may be a personal computer, a personal digital assistant, a personal digital assistant (PDA), a personal digital assistant (PDA), a personal digital assistant E-mail client, etc.), any form of mobile phone, or any other type of computing or communication platform, but the invention is not so limited.

1, the code generation apparatus 100 generates and outputs an image including a code and a background. The code generation apparatus 100 can output the image on a display unit and output the image in a manner of replicating the image on the surface of an object such as paper or cloth. The terminal device 200 may be operatively connected to the code generation device 100 by executing application software. The terminal device 200 recognizes all or a part of the image with the provided camera, and receives information corresponding to the recognized part from the code generation device 100.

1, in (1), the code generating apparatus 100 generates a code based on a method to be described later. (2), the terminal device 200 installs and executes the application software. (3), the terminal device 200 scans all or part of the image including the code. The terminal device 200 receives information corresponding to the scanned area from the code generation device 100 in step (4).

2 shows an overall configuration of a code generation apparatus 100 according to an embodiment.

A code generation device for wirelessly communicating with a terminal device for scanning an image, comprising: an image reception unit (107) for receiving an image scanned from the terminal device; And an image recognition unit (108) for transmitting different information to the terminal according to the ratio of the scanned area and the scanned area of the image occupied in the entire area of the image.

The image receiving unit 107 receives the scanned image from the terminal device. The scanning of the image by the terminal device may mean that the image is captured by the camera provided in the terminal device.

The image recognizing unit 108 transmits different information to the terminal according to the ratio of the scanned area and the scanned area of the image in the entire image area.

The scanned area of the image means an area scanned by the terminal device from the entire image. The scanned region may be an entire image, or it may be a specific portion of an image. Even if the sizes of the specific portions of the scanned image of the terminal device are the same, the positions in the entire image may be different from each other.

If the scanned area is the entire image, the percentage occupying the entire area of the image is 100 percent. If the area scanned by the terminal device is a specific part of the image, the percentage occupied by the entire image area is less than 100 percent.

As such, the image recognition unit 108 can transmit different information to the terminal device based on the ratio of the scanned area and the entire image of the area. A detailed description thereof will be described later with reference to FIG.

The image recognition unit 108 compares the background included in the received image with the background stored in the database to specify the background of the received image.

The scanned image of the code recognition area 201 output by the terminal device 200 is transmitted to the code generation device 100. [ The code recognition unit 108 compares the background included in the received image with the background stored in the database to specify the background of the received image. Specifying the background of the image means that the background of the received image is treated as the background of any one of a plurality of images stored in the database.

The image recognition unit 108 extracts the contour of the background included in the image and compares the extracted contour with the contour of the background of the image stored in the database to determine whether the extracted contour is a predetermined ratio of the contour length of the background of the image on the database The background of the received image is specified as the background of the database image.

The image recognition unit 108 can extract a contour line with a change in color. A point where the amount of change in color is equal to or greater than the reference value can be defined as a point on the contour line. The image recognizing unit 108 may set the database image background to be the same as the background of the received image if the extracted outline matches 80% or more of the contour length of the background of the image on the database.

Even if the code contained in the image is the same, different information can be transmitted to the code device if the background included in the image is specified differently. Since the background itself can be an element for determining information, the image recognition unit 108 specifies the background of the received image.

The image recognition unit 108 extracts a code from an image whose background is specified.

The image recognition unit 108 extracts the code included in the image after specifying the background of the image. An image contains a background and code. The code includes only the figure 12 described below.

The image recognition unit 108 converts the image specific to the background in black and white. In order to extract only the code from the monochrome converted image, the image recognition unit 108 adjusts at least one of saturation, brightness, contrast, color, and sharpness. The saturation can be adjusted in the range of 0 to 401%. The brightness can be adjusted in the range of 0 to 100%. The contrast can be adjusted in the range of 0 to 100%. In the case of RGB, the color can be adjusted in the range of 0 to 255 for each of red and green blue. When the color is CMYK, each of blue, purple, and yellow black can be adjusted in the range of 0 to 100. The sharpness can be adjusted in the range of 0 to 100%.

The image recognition unit 108 adjusts at least one of saturation, brightness, contrast, color, and sharpness to stop the adjustment and extract the figure 12 if the figure 12 has two or more differences in background and color values . Extracting the figure 12 is extracting the code.

If the color is RGB, if at least one of the red and green blues of the figure 12 has a difference of at least 2 from the value of at least one of the background red and green blues located at the boundary of the figure 12, Stop. The respective values of the red and green blue are RGB values.

If the hue is CMYK, if at least one of the values of the blueness, blueness, and yellow test of the figure 12 is greater than or equal to at least one value of at least one of the blueness, , And stops the adjustment. The respective values of blue, purple, and yellow are CMYK values.

The image recognition unit 108 separates the background and the code from the image, and extracts the code.

FIG. 3 shows a terminal device that photographs the same object 300 at different distances.

The terminal device according to FIG. 3 captures the same object 300 at different distances to acquire different information. There are the same background and code on the surface of the same object 300. However, the terminal apparatus can receive different information according to the distance that the terminal 300 scans the object 300.

4 shows a terminal device to which a magnifying glass 202 is coupled.

The terminal device can combine the magnifying glass 202 and collect information based on a code that is hard to be visually recognized.

Figure 5 shows a code according to an embodiment. The code here refers to the code contained in the image. If the image contains no background, the image itself may be code. If the image includes a background, the code according to FIG. 5 may be an extracted code by separating the background and the code after specifying the background of the image.

The image recognition unit 108 identifies cells included in the scanned image when the number of the graphics included in the same group among the graphics included in the extracted code is equal to or greater than a predetermined number.

Shapes in which the difference in area is within a predetermined range may be included in the same group. In the example according to Fig. 5, the first group figure 401 is the largest figure. The second group graphic 402 is the middle sized graphic. The third group graphic 403 is the smallest sized graphic. According to FIG. 5, there are three groups.

The predetermined number is four, for example.

If the number of figures included in the same group included in the scanned area is equal to or greater than the existing number, the image recognition unit 108 specifies a cell included in the scanned image. Cells have different sizes from group to group. The cell 601 based on the first isotope 401, the cell 602 based on the second isotope 402 and the cell 603 based on the third isotope 403 are different from each other Size.

In the embodiment according to FIG. 5, the cell 601 based on the first isoform 401 is a cell formed by the first group line segment 501. The cell 602 based on the second isoform 402 is the smallest cell among the cells formed by the second group line segment 502. The cell 603 based on the third isoform 403 is the smallest cell among the cells formed by the third group segment 503.

The image recognition unit 108 transmits information matched to the specified cell to the terminal device. The image recognition unit 108 may determine which area of the entire image is scanned based on the arrangement of the graphics included in the scanned area of the terminal. That is, a portion of the image on the database matching the scanned area is detected by comparing the graphics included in the scanned area and the graphics of the image stored on the database. Finally, the image recognizing unit 108 extracts and specifies the cell including the part.

The image recognition unit 108 transmits information matched to the specified cell to the terminal device. Information matched to the cell can be defined in advance by the code generation device. The information matched to each cell can be changed later.

The image recognizing unit 108 recognizes that each of the plurality of graphic cells included in the different groups is equal to or greater than a predetermined number and that the plurality of cells are matched to the group including the larger graphic among the plurality of cells, Specify.

Each group includes figures of different sizes, and the size of the matched cells differs for each group. Referring to FIG. 5, there are a total of three groups, one group includes a first isoform 401, another group includes a second isoform 402, Includes a three-arch type (403).

The cell 601 matched to the group including the first isoform 401 is a cell formed by the first group line segment 501 and the cell 602 matched to the group including the second isoform 402 And is the smallest cell among the cells formed by the second group line segments 502. The cell 603 including the third isoform 403 is the smallest cell among the cells formed by the third group line segment 503. The larger the size of the figure included in the group, the larger the size of the cell matched to the group.

5, when a terminal device scans a cell 601 composed of a first group line segment 501, the figure included in the cell includes a first isoform 401, a second isoform 402, And an isoform 403 are all included. The first isoform 401, the second isoform 402, and the third isoform 403 included in the cell 601 are all equal to or greater than the predetermined number. That is, the cell 601 composed of the first group line segment 501 includes both the cell 602 composed of the second group line segment 502 and the cell 603 composed of the third group line segment 503.

At this time, the image recognizer 108 selects a cell 601 composed of a first group line segment 501, which is a cell matched to a group including a figure having a larger size among the plurality of cells, And transmits the matched information to the terminal device.

Accordingly, when the terminal device captures an image from the printed object 300, if the pattern is scanned close to the scanned area, the figure with the number of figures included in the scanned area is equal to or greater than a predetermined number, to be.

When a terminal captures an image from an object 300 on which a pattern is printed, as the pattern is further scanned farther, a figure whose number of figures included in the scanned area is equal to or greater than a predetermined number, In addition, relatively large figures may be included. That is, a cell matched to a group including a figure having a larger size among the predetermined number of graphic objects included in the scanned area is determined as a cell based on information transmission.

Based on the above-described principle, the image recognition unit 108 can transmit different information to the terminal device based on the ratio of the scanned area and the entire image of the area.

As a result, the image recognition unit 108 transmits specific information to the terminal device based on the specified background and the specified cell from the scanned image.

Referring to FIG. 7, the center of the figure 12 may be located on a dotted line or inside a circle 18 indicated by a dashed line based on the set derivation distance 15. If the center of the graphic 12 is located on the one dotted chain line or inside the circles 18 indicated by the one-dotted chain line, there is no restriction on the position.

The center of the figure 12 is moved in any direction by a derived distance 15 or less from the lattice point 11 according to the derived distance 15. There is no limitation on the direction in which the center of the figure 12 is moved if the distance is 15 or less.

In another embodiment, the center of the figure 12 is moved by a derivative distance 15 or less from the lattice point 11 according to the derivation distance 15, and the center of the figure 12 is divided into a horizontal line 13 and a vertical line 14). ≪ / RTI >

Lattice Distance 16 The input unit 103 inputs a lattice distance 16 which is a distance between any one of the lattice points 11 and the lattice point 11 closest to any one of the lattice points 11. Figure 6 shows the lattice distance 16 which can be defined as the distance between any one horizontal line 13 and any one horizontal line 13 and the nearest horizontal line 13 . The lattice distance 16 may be defined as the distance between any one of the vertical lines 14 and the vertical line 14 closest to any one of the vertical lines 14.

The code generation unit 104 generates a grid pattern 10 having the grid distance 16 so as to generate a grid pattern 12 that is centered at a distance less than the derived distance 15 from each grid point 11 And arranges it on the grid pattern 10 to generate and output a code. The lattice distance 16 and the lattice pattern 10 have been described above. Figure 6 shows a code comprising a figure 12 arranged on a grid pattern 10 based on a grid pattern 10 and an input grid distance 16 and a derivation distance 15. The code generation unit 104 outputs the code to an object such as a display unit or paper such as a display device.

The horizontal line 13, the vertical line 14, the lattice point 11 and the lattice distance 16 according to FIG. 6 are shown for the sake of explanation. 16). The code may include only graphics 12.

The code generating apparatus 100 includes a horizontal line grating 11 for inputting the number of lattice points 11 of a horizontal line 13 which is the number of lattice points 11 located on any one horizontal line 13 included in the lattice pattern 10, And a point number input unit 105. When the number of lattice points 11 is inputted to the horizontal line 13, all the horizontal lines 13 included in the lattice pattern 10 include the lattice points 11 corresponding to the number. The lattice points 11 may be equally spaced at a lattice distance 16.

Fig. 8 shows an arbitrary figure 12 and a circle 18 included in the figure 12. Fig.

The lattice distance 16 is at least seven times the radius of the circle 18. In detail, the lattice distance 16 is 7 to 8 times the radius of the circle 18. The figure 12 is not limited to the circle 18, but may be any figure 12. In addition, the circle 18 may mean the figure 12 itself, but it may mean the circle 18 having the largest radius among the circles 18 included in the figure 12.

8, for a circle 18 having the largest radius among the circles 18 that the figure 12 can include, the lattice distance 16 is a radius of the circle 18 of the circle 18, It can be more than 7 times.

Referring to FIG. 8, the center of the figure 12 may be the center of the circle 18 having the largest radius included in the figure 12.

The derivation distance 15 is less than 1.15 times the radius of the circle 18. Here, the circle 18 may mean the figure 12 itself, but it may mean the circle 18 having the largest radius among the circles 18 included in the figure 12. Since the derivation distance 15 is 1.15 times or less the radius length of the circle 18, the figure 12 has a radius of 1.15 times the radius of the circle 18 having the largest radius included in the figure 12 The center of the circle 18 may be located at the center.

If the length of the derivation distance 15 becomes too long, one of the figures 12 may overlap with the other figure 12, and accordingly the accuracy of code recognition may be lowered. The derivative distance 15 may be different for each figure located at the lattice point. Also, all figures can move to the same derivation distance 15.

In the group distinction 1 according to FIG. 12, positions 1, 2, 4 and 5 are one cell 19, positions 3, 6 and 9 are another cell 19 and positions 7 and 8 are another cell 19 Cell 19. The specification of the cell 19 is not limited to the group distinction 1, and there is no limitation on the method of specifying the cell 19 as in the group distinction 2 to 6.

Fig. 13 shows a terminal device 200 that outputs the code recognition area 201. Fig. The terminal device 200 can execute the above-described application program and output the code recognition area 201. [ When the code recognition area 201 scans a specific cell 19 of the code, the code generation device 100 transmits information corresponding to the cell 19 to the terminal device 200. That is, the code recognized in the code recognition area 201 is transmitted to the code generation device 100 in real time, and the code generation device 100 transmits the information matched to the recognized code to the terminal device 200 .

The code recognition area 201 can simultaneously scan a plurality of cells shown in Fig. At this time, it is assumed that the code generating apparatus 100 has matched one information for each cell in the example of FIG. The code generating apparatus 100 transmits to the terminal device 200 information in which the code recognition area 201 has matched the largest cell among the plurality of scanned cells.

When the code recognition area 201 of the terminal device 200 scans the specific cell 19 of the code for more than 1 second and less than 2 seconds, the code generation device 100 outputs green light on the display of the terminal device 200 A light emission command is transmitted to the terminal device.

When the code recognition area 201 of the terminal device 200 scans the specific cell 19 of the code for more than 1 second and less than 2 seconds, the code generation device 100 outputs a yellow light from the display of the terminal device 200 A light emission command is transmitted to the terminal device.

When the code recognition area 201 of the terminal device 200 scans the specific cell 19 of the code for more than 2 seconds but less than 3 seconds, the code generation device 100 outputs an orange light from the display of the terminal device 200 A light emission command is transmitted to the terminal device.

When the code recognition area 201 of the terminal device 200 scans the specific cell 19 of the code for more than 3 seconds but less than 4 seconds, the code generation device 100 generates red light from the display of the terminal device 200 And transmits a light emission command to the terminal device to output the light emission command.

It is obvious that the code generating apparatus 100 transmits information corresponding to the specific cell 19 to the terminal apparatus 200 separately from the light emitting command. The code generation apparatus 100 transmits a light emission command with a high visibility color to the terminal device 200 as the terminal device 200 scans a specific cell 19 for a long time, It can be reminded that the terminal device 200 has received the information.

If the number of figures included in the code scanned by the code recognition area 201 of the terminal device 200 is less than a predetermined number, the code generation device 100 generates a zoom-out command so that the camera included in the terminal device 200 zooms out Lt; / RTI > When the number of graphic objects is equal to or greater than a predetermined number, the code generating device 100 can check which part of the entire code the terminal device 200 scans. If the number of figures is less than the predetermined number, the distance between the terminal device 200 and the cord must be further increased. However, even if the user does not further distant the distance between the terminal device 200 and the code, the code generating device 100 transmits a zoom-out command so that the camera included in the terminal device 200 zooms out.

More specifically, the user himself can recognize that the number of graphic objects is less than a predetermined number, and can place the terminal device 200 away from the code. Therefore, the code generating apparatus 100 may be configured to transmit the code to the terminal device 200 after 10 seconds from the point of time when the code recognition area 201 of the terminal device 200 has detected that the number of the graphics included in the scanned code is less than the predetermined number And sends a zoom-out command so that the included camera zooms out. The 10 seconds is the minimum time when the user of the terminal device 100 determines that the number of the graphic objects is less than the predetermined number.

Likewise, if the saturation of the figure included in the code scanned by the code recognition area 201 of the terminal device 200 is less than the reference value, the code generation device 100 determines that the lamp included in the terminal device 200 is turned on Command. Saturation is below the standard, which means that the area around the code is dark. Accordingly, the code generating apparatus 100 transmits a lamp-on command to turn on the lamp included in the terminal apparatus 200, thereby guiding the terminal apparatus 200 to increase the saturation of the code to be scanned.

More specifically, the user can recognize that the figure is not clearly visible, and turn on the light to adjust the saturation around the code. Therefore, the code generating apparatus 100 may be configured such that, after 10 seconds from the point of time when the code recognition area 201 of the terminal device 200 has detected that the saturation of the figure included in the code scanned by the code recognition area 201 is less than the reference value, And sends a zoom-out command so that the camera zooms out. The 10 seconds is a minimum time when the user of the terminal device 100 determines that the saturation of the graphic form is less than the reference value.

14 shows the background of the code and the graphic 12 of the code. A series of processes in which the code generating apparatus 100 generates a code by disposing the figure 12 on the grid pattern 10 has been described above. The grid pattern 10 is an invisible grid pattern 10 that is introduced to explain the arrangement of the graphic 12 and is not exposed to the actual code. It has been described above that the graphic form 12 itself may exist in various forms. Further, the background on which the graphic object 12 is placed is also not limited. In Fig. 13, the background is red, but the color is not limited thereto. In addition, a background image may be formed of a plurality of colors.

Apart from the background, the color of the figure 12 may be white, black, or a similar color to the background. The shape of the figure 12 is not limited thereto, and one figure 12 may include a plurality of colors. Also, one of the figures 12 and the other figure 12 may include different colors.

The transparency may be different even if the color of the graphic 12 is white as shown in Fig. The transparency may range from 0 to 98%. Not only the transparency but also the brightness and contrast value for the specified color can be set variously. The range of the brightness is 0 to 100%. The range of contrast is 0 to 100%. The contrast is an attribute employed in known editing software, and is a difference between lightness and darkness. The higher the contrast, the brighter the lighter the darker the darker the color.

FIG. 15 illustrates a process in which the code generation apparatus 100 recognizes the background of an image from an image scanned by the terminal device 200. FIG. The scanning of the image by the terminal device 200 may mean taking an image through a camera provided in the terminal device 200. The scanned image of the code recognition area 201 output by the terminal device 200 is transmitted to the code generation device 100. [ The code generating apparatus 100 compares the background included in the received image with the background stored in the database to specify the background of the received image. That is, as shown in FIG. 15, the code generation apparatus 100 specifies the background included in the image transmitted by the terminal device 200 as a 'rabbit holding a load' background.

The code generating apparatus 100 extracts the contour of the background included in the received image. Based on Fig. 15, the background is rabbit, and the code generation device extracts the outline of the rabbit. At this time, the code generation apparatus can extract the contour line by changing the color. A point where the color change amount is equal to or greater than the reference value is defined as a point on the contour line.

The code generating apparatus 100 extracts the contour of the background contained in the image and compares it with the background of the image stored in the database. It consists of the outline of the background of the image stored in the database. If the extracted outline matches 80% or more of the outline length of the background of the image on the database, the database image background is set to be the same as the background of the received image by comparing the extracted outline with the outline of the background of the image stored in the database. That is, the code generating apparatus 100 specifies the background of the received image as the background of the database image.

The code generating apparatus 100 recognizes the code included in the image according to a method described later after specifying the background of the received image.

The function performed by the code generating apparatus 100 according to FIG. 15 may be a function performed by the code recognizing unit 108 included in the code generating apparatus 100.

16 shows a process in which the code generating apparatus 100 recognizes a code from an image recognized by the terminal apparatus 200. [ The code generation device 100 extracts the code included in the image after specifying the background of the image. An image contains a background and code. The code includes only the figure 12 described above.

The code generating apparatus 100 converts the background-specific image into black and white. A specific method of switching between black and white will be described later with reference to FIG. In order to extract only the code from the monochrome converted image, the code generating device 100 adjusts at least one of saturation, brightness, contrast, color, and sharpness. The saturation can be adjusted in the range of 0 to 401%. The brightness can be adjusted in the range of 0 to 100%. The contrast can be adjusted in the range of 0 to 100%. In the case of RGB, the color can be adjusted in the range of 0 to 255 for each of red and green blue. When the color is CMYK, each of blue, purple, and yellow black can be adjusted in the range of 0 to 100. The sharpness can be adjusted in the range of 0 to 100%.

The code generating apparatus 100 controls at least one of saturation, brightness, contrast, color, and sharpness so that if the figure 12 has two or more differences in background and color values, the adjustment is discontinued and the figure 12 is extracted . Extracting the figure 12 is extracting the code.

If the color is RGB, if the sum of the respective values of the red and green blues of the figure 12 is different from the sum of the respective values of the red and green blues of the background located at the boundary of the figure 12, Stop.

If the color is CMYK, if the sum of the values of the blue, green, and yellow colors of the figure 12 is different from the sum of the respective values of the red and green colors of the background located at the boundary of the figure 12, Stop the adjustment.

The adjustment is stopped, and the code generating apparatus 100 separates the background and the code from the image, and extracts the code. Then, the terminal device 200 transmits information matched to the cell 19 including the scanned portion to the terminal device 200.

The function performed by the code generating apparatus 100 according to FIG. 16 may be a function performed by the code recognizing unit 108 included in the code generating apparatus 100.

17 shows various methods by which the code generating apparatus 100 switches the image in black and white. The code generating apparatus 100 switches a specific image to black and white. At this time, the specific image is switched to black and white based on any one of red-based black-and-white conversion, green-based black-and-white conversion, and blue-based black-and-white conversion.

The red-based black-and-white conversion is a bright conversion of the red-based color in the original (18) image. A bright conversion is that it converts to a white series.

The black-and-white conversion of the green series is to brightly convert the color of the green series in the original (18) image. A bright conversion is that it converts to a white series.

The black-and-white conversion of the blue system converts the color of the blue system from the original image 18 brightly. A bright conversion is that it converts to a white series.

FIG. 18 shows matching information for each area of a business card scanned by the terminal device 200 in a business card including a code generated by the code generating apparatus 100 according to an example. 18, when the terminal device 200 scans the logo, the terminal device 200 receives the website address of the company from the code generation device 100, and the terminal device 200 transmits the website address . When the terminal device 200 scans the printed portion of the name and rank, it receives an address book storage command from the code generation device 100 to store the name and rank in the address book of the terminal device 200. Further, when the terminal device 200 scans a portion where the telephone number is printed, the terminal device 200 receives a calling instruction from the code generating device 100 so that the terminal device 200 calls the number.
