Description

  The present invention relates to an ID card creation apparatus and creation method for creating an ID card on which a face image is printed.

  An ID card (Identification Card) such as a license may be printed with a face image of the ID card owner. This face image is often obtained by photographing the face of the ID card owner with a digital camera or video camera. Since the face image printed on the ID card is used for identity verification, when creating the ID card, it is necessary to check the eye open state of the photographed person in the photographed face image, and to shoot again if the eyes are closed is there. For example, a system has been proposed in which a photographed face image is displayed on a monitor, photographing is performed again when a blink is found, and photographing is repeated until desired face image data is obtained (see, for example, Patent Document 1).

  However, in the conventional system, since a bust shot image is displayed on the monitor, the display of the eye portion becomes small, and it is difficult to visually check the open eye state. There has also been proposed a method for automatically determining the eye open state of a captured face image, but the operator does not know whether the eye position is correctly detected, and there is a possibility that the eye open state is not correctly determined.

  Further, in face authentication software that performs identity verification, the position of the eyes is an important parameter as the feature amount of the face image. In order to improve the authentication accuracy of the face authentication software, accurate information on the eye position is required.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a schematic configuration of an ID card creation device according to an embodiment of the present invention. The ID card creation device 1 includes an input unit 101 to which identification information for identifying a subject is input, an imaging unit 102 that captures a face of the subject and generates image data, and the subject's person in the image data. A detection unit 103 that detects a predetermined region including the eye and the position of the eye, a display unit 104 that displays image data and a marker, an instruction reception unit 105 that receives an instruction to change the display position of the marker, identification information, image data, And a control unit 110 that controls transfer of information about the display position of the marker, and a creation unit 140 that creates an ID card using the image data and the identification information.

  Further, the ID card creation device 1 includes a storage unit 130 that stores facial feature amounts of a plurality of people, a calculation unit 121 that calculates facial feature amounts of the photographed person, and feature amounts from the storage unit 130. An extraction unit 122 that extracts the feature amount, a determination unit 123 that performs identity verification based on the similarity between the calculated feature amount and the extracted feature amount, an update unit 124 that updates data stored in the storage unit 130, and a creation A management unit 125 that grants ID card creation permission to the unit 140 is connected.

  And the ID card production apparatus 1 which consists of such a structure produces the ID card with which the to-be-photographed person's 10 face image was printed. Here, the ID card is, for example, a license such as a car driver's license, a cash card, a credit card, an employee card, a membership card, an identification card, a medical card, or the like.

  The input unit 101 is input with identification information for identifying the subject 10 who is applying for the issuance of an ID card. The input unit 101 can be configured with, for example, a mouse or a keyboard.

  The identification information input to the input unit 101 includes, for example, the name and personal identification number of the subject 10. Further, the identification information may include the address of the subject 10 and the date of birth. The input unit 101 notifies the control unit 110 of the input identification information.

  Further, the imaging unit 102 captures at least a part of the upper body including the face of the subject 10. The imaging unit 102 is, for example, a digital camera or a video camera, and uses a red R, green G, and blue B color filter CCD. The imaging unit 102 performs imaging by an operator operating an operation unit (not shown). Image data obtained by photographing the subject 10 by the imaging unit 102 is output to the detection unit 103, the display unit 104, and the control unit 110.

  The detection unit 103 detects the eye position of the subject 10 from the image data received from the imaging unit 102 using a known method.

  For example, the detection unit 103 converts image data that is color multi-value pixel data into grayscale pixel data, and calculates a density value of each pixel. Next, the detection unit 103 counts the number of black pixels having a density value equal to or less than a predetermined threshold in the horizontal direction of the image. When this count value is viewed in the vertical direction, the count value increases in areas corresponding to eyebrows, eyes, nostrils, and mouth. Accordingly, among the four areas where the count value increases, the second from the top in the vertical direction of the image corresponds to the eye. Using such characteristics, the detection unit 103 can detect the position of the eyes.

  The detecting unit 103 can also store images of the corners of the eyes and the eyes in advance as templates, and can detect the positions of the eyes by template matching.

  Furthermore, the detection unit 103 sets a rectangular area of a predetermined size that includes the detected eye position in the center portion. Then, the detection unit 103 notifies the display unit 104 of the detected eye position (coordinates in the image) and the vertex position (coordinates in the image) of the rectangular area.

  The display unit 104 displays the image data received from the imaging unit 102. In addition, the display unit 104 enlarges and displays an image of a portion corresponding to a rectangular region surrounded by the vertex position notified from the detection unit 103 in the image data received from the imaging unit 102. Further, the display unit 104 displays a marker superimposed on the eye position notified from the detection unit 103 in the enlarged rectangular region image.

  2A to 2D show examples of images displayed on the display unit 104. FIG. As shown in FIG. 2A, the display unit 104 includes an image 201 of the subject 10 photographed by the imaging unit 102, an enlarged image 202 of a rectangular area centered on the eyes of the subject 10, and eyes. A marker 203 indicating the position is displayed. Since an enlarged image of a rectangular area centered on the eyes is displayed on the display unit 104, the operator can easily visually recognize the eye-opening state of the person to be photographed 10. For example, as shown in FIG. 2B, the operator can easily visually recognize from the enlarged image 202 that the subject 10 is in a state where his eyes are closed.

  The instruction receiving unit 105 receives an instruction to change (correct) the display position of the marker 203 in the enlarged image 202 displayed on the display unit 104 from the operator. The operator visually recognizes the display position of the marker 203 in the image 202 enlarged and displayed on the display unit 104. If the display position of the marker 203 and the eye position of the subject 10 are misaligned, the operator receives the instruction reception unit 105. Thus, the display position of the marker 203 can be corrected to the correct position.

  For example, as shown in FIG. 2C, when the display position of the marker 203 is shifted from the position of the eye of the subject 10, the operator shows the position shown in FIG. Thus, the display position of the marker 203 can be changed to the correct position (the position of the eye of the subject 10).

  By the way, at least a part of the display unit 104 and the instruction receiving unit 105 can be configured by a touch panel, for example. In the case of a touch panel, the operator can touch the marker 203 and easily move the position of the marker 203. Further, the display unit 104 may be configured with a liquid crystal display and the instruction receiving unit 105 may be configured with a mouse, and the position of the marker 203 may be moved by drag and drop.

  When the display unit 104 receives confirmation from the operator of the display position of the marker 203 via the instruction reception unit 105, the display unit 104 notifies the control unit 110 of coordinates indicating the display position of the marker 203 in the image data. Thereby, the control unit 110 can acquire the exact position (coordinates) of the eye of the subject 10 in the image data.

  The control unit 110 calculates the image data received from the imaging unit 102, the eye position of the subject 10 notified from the display unit 104, and the identification information of the subject 10 notified from the input unit 101. To 121. In addition, the control unit 110 outputs the identification information of the subject 10 notified from the input unit 101 to the extraction unit 122. Further, the control unit 110 outputs the image data received from the imaging unit 102 to the creation unit 140.

  The calculation unit 121 calculates the facial feature amount of the subject 10 using the image data received from the control unit 110 and the position of the eye of the subject 10. The feature amount of the face is, for example, the position of the eyes, the mutual positional relationship between the eyes and the nose, the mouth, the ears, the eyebrows and the like, the shape of the face, the eyes, the nose, the mouth, the ears, the eyebrows, and the like. The facial feature amount can be calculated by a known method.

  Then, the calculation unit 121 outputs the calculated facial feature amount of the subject 10 to the determination unit 123. Further, the calculation unit 121 outputs the identification information of the subject 10 and the calculated feature amount of the face of the subject 10 to the update unit 124.

  The storage unit 130 stores combinations of facial feature amounts and identification information for a plurality of humans, and is composed of, for example, a hard disk. For example, the storage unit 130 stores a feature amount of a human face photographed in the past to create an ID card and the identification information of the person in combination.

  The extraction unit 122 searches the storage unit 130 and extracts a feature amount combined with the same identification information as the identification information received from the control unit 110 (identification information of the subject 10). The extraction unit 122 outputs the extracted feature amount to the determination unit 123. If the same identification information as the identification information received from the control unit 110 is not stored in the storage unit 130, the extraction unit 122 notifies the determination unit 123 that there is no feature amount to be extracted.

  The determination unit 123 compares the feature amount of the face of the subject 10 received from the calculation unit 121 with the feature amount extracted from the storage unit 130 by the extraction unit 122 and calculates the similarity. For example, the similarity can be calculated from the standard Euclidean distance of the feature amount. The determination unit 123 determines that they match if the calculated similarity is greater than or equal to a predetermined threshold. On the other hand, the determination unit 123 determines that there is a mismatch when the calculated similarity is less than a predetermined threshold.

  Therefore, it can be determined whether or not the subject 10 is the person who has created an ID card in the past.

  The determination unit 123 does not perform determination when notified from the extraction unit 122 that there is no feature amount to be extracted. Therefore, the determination result by the determination unit 123 is one of coincidence, disagreement, and undecided. The determination unit 123 notifies the update unit 124 and the management unit 125 of the determination result.

  When the determination result of the determination unit 123 is “match”, the update unit 124 stores the facial feature amount of the subject 10 received from the calculation unit 121 of the subject 10 stored in the storage unit 130. Overwrite or additionally write to the feature value, and update the data.

  In addition, when the determination result of the determination unit 123 is “undetermined”, the update unit 124 newly combines the facial feature amount of the subject 10 received from the calculation unit 121 and the identification information, and newly stores the storage unit 130. Write to.

  Accordingly, the storage unit 130 can store the latest information on the facial feature amount of the subject 10.

  Based on the determination result of the determination unit 123, the management unit 125 determines whether the ID card issuance (creation) is permitted or not, and notifies the creation unit 140 of the permission. For example, when the determination result of the determination unit 123 is “match”, the management unit 125 permits the creation unit 140 to create an ID card. On the other hand, when the determination result of the determination unit 123 is “mismatch”, the management unit 125 does not permit the creation unit 140 to create an ID card.

  When the determination result of the determination unit 123 is “undetermined”, the management unit 125 may permit the creation unit 140 to create an ID card, or entrust the operator to determine whether or not to allow ID card creation. Also good.

  When the creation of an ID card is permitted by the management unit 125, the creation unit 140 creates an ID card using the image data received from the control unit 110. For example, the creation unit 140 includes a card cassette in which the card material of the ID card is stored, a print unit of each color of yellow Y, magenta M, cyan C, and black B, an application unit of an ultraviolet curable resin, and an ultraviolet irradiation unit. With.

  The creation unit 140 converts image data of the three primary color signals of red R, green G, and blue B into density information of yellow Y, magenta M, and cyan C in order to color-print the face image of the subject 10. . Then, the creation unit 140 takes out one card material from the card cassette, sequentially prints yellow Y, magenta M, and cyan C, and prints the face image of the subject 10 by color printing. Furthermore, the creation unit 104 prints the character information such as the address and name of the subject 10 in black B.

  Then, the creation unit 140 applies an ultraviolet curable resin to the card material, and then cures the resin by irradiating ultraviolet rays to create an ID card. The creation unit 140 may perform hot stamping (foil pressing) of the ID card.

  Next, an example of an ID card creation method using the ID card creation device 1 will be described with reference to the flowchart shown in FIG.

  (Step S <b> 101) Identification information of the photographed person 10 who applies for creation of an ID card is input via the input unit 101.

  (Step S <b> 102) By the operation of the operator, the imaging unit 102 captures at least a part of the upper body including the face of the subject 10 (bust shot). The imaging unit 102 outputs the captured image data to the detection unit 103, the display unit 104, and the control unit 110.

  (Step S <b> 103) The detection unit 103 detects the position (coordinates) of the eyes in the face image of the subject 10 from the image data received from the imaging unit 102. The detection unit 103 sets a rectangular area of a predetermined size including the eyes in the face image of the subject 10 and detects the position (coordinates) of the vertex of the rectangular area. The detection unit 103 notifies the display unit 104 of the eye position and the vertex position of the rectangular area.

  (Step S104) The display unit 104 displays the image data received from the imaging unit 102 on the display. In addition, the display unit 104 enlarges and displays a rectangular area surrounded by the vertex positions notified from the detection unit 103 and displays a marker superimposed on the eye position of the subject 10 notified from the detection unit 103.

  (Step S105) The operator confirms the eye open state of the subject 10 from the rectangular area enlarged and displayed in Step S104. If the eye of the subject 10 is open, the process proceeds to step S106. If the eye is meditated or half-opened, the process returns to step S102, and imaging is performed again. Since the area around the eye of the subject 10 is enlarged, the eye-opened state of the subject 10 can be easily recognized.

  (Step S106) The operator confirms whether or not the position of the marker displayed in Step S104 is correctly aligned with the eye position of the subject 10. If they do match, the process proceeds to step S108, and if they do not match, the process proceeds to step S107.

  (Step S <b> 107) The operator corrects the marker position via the instruction receiving unit 105 so that the marker position displayed on the display unit 104 matches the eye position of the subject 10.

  For example, when the display unit 104 and the instruction receiving unit 105 are configured by a touch panel, the operator can correct the position of the marker by touching and moving the marker.

  (Step S <b> 108) The display unit 104 calculates the position of the marker in the image data and notifies the control unit 110. The control unit 110 can acquire accurate information on the eye position of the subject 10 from the display unit 104.

  (Step S109) The calculation unit 121 receives the image data and the information on the eye position of the subject 10 from the control unit 110, and calculates the feature amount of the face of the subject 10 using these.

  (Step S110) The extraction unit 122 receives the identification information of the subject 10 input in Step S101 from the control unit 110, searches the storage unit 130, and searches for the same identification information as this identification information. The storage unit 130 stores a combination of feature amounts and identification information of a plurality of human faces that have created ID cards in the past.

  (Step S111) If the same identification information as the identification information of the subject 10 input in step S101 is stored in the storage unit 130, the process proceeds to step S112, and if not, the process proceeds to step S115.

  (Step S <b> 112) The extraction unit 122 extracts the feature amount combined with the same identification information as the identification information of the subject 10 from the storage unit 130.

  (Step S113) The determination unit 123 calculates the similarity between the feature amount calculated in step S109 and the feature amount extracted from the storage unit 130 in step S112.

  (Step S114) When the similarity calculated in Step S113 is equal to or greater than a predetermined threshold value, it is determined that the feature amount calculated in Step S109 matches the feature amount extracted from the storage unit 130 in Step S112. . That is, it is determined that the person to be photographed 10 matches the person who created the ID card in the past corresponding to the identification information input in step S101 (is the person himself), and the process proceeds to step S115.

  On the other hand, if the similarity calculated in step S113 is less than the predetermined threshold, the photographed person 10 does not match the person who created the ID card in the past corresponding to the identification information input in step S101. It is determined. In this case, since it is considered that the photographed person 10 is impersonating another person and trying to create an ID card, the ID card creation process is terminated without creating the ID card.

  (Step S115) The management unit 125 gives the creation unit 140 permission to create an ID card.

  (Step S116) Using the image data received from the control unit 110, the creation unit 140 creates an ID card on which the face image of the subject 10 is printed.

  (Step S117) The updating unit 124 combines (overwrites or additionally writes) the identification information of the subject 10 and the similarity calculated in Step S113 in the storage unit 130, and stores the stored data in the storage unit 130. Update.

  As described above, according to the ID card creation device 1 according to the present embodiment, since the area around the eye of the subject 10 is enlarged and displayed on the display unit 104, the operator can open the face image of the subject 10. It is easy to visually confirm the state, and it is possible to prevent a blinking image from being printed on the ID card.

  Furthermore, according to the ID card creation device 1 according to the present embodiment, the position of the eye of the subject 10 detected by the detection unit 103 is indicated with a marker in the image of the peripheral region of the eye enlarged and displayed by the display unit 104. The marker position correction instruction can be received from the operator via the instruction receiving unit 105. Therefore, the ID card creation device 1 can acquire accurate information about the eye position of the subject 10. As a result, even if it is difficult for the detection unit 103 to detect the position of the eye, such as when the subject 10 has small eyes or the subject 10 has an eye patch, the operator can By receiving an instruction to correct the marker position, it is possible to acquire accurate information about the eye position of the subject 10.

  Since the eye position is an important parameter when the calculation unit 121 calculates the facial feature amount, it is possible to calculate the feature amount suitable for face authentication by acquiring accurate information about the eye position. The authentication accuracy can be improved. Further, by comparing the feature amount calculated by the calculation unit 121 and the feature amount stored in the storage unit 130, it is determined whether or not the subject 10 is the person who created the ID card in the past. It can be determined with high accuracy.

  As described above, according to the ID card creating apparatus 1 according to the present embodiment, it is easy for the operator to visually check the open state of the face image of the person to be photographed 10, and to create the ID card on which the blink image is printed. In addition to preventing, it is possible to acquire accurate information on the eye position in the face image.

  Furthermore, the accuracy of identity verification at the time of ID card creation is improved, and illegal issue of an ID card due to impersonation of another person can be effectively prevented.

  In the above embodiment, as shown in FIG. 2, the display unit 104 simultaneously displays a face image (bust shot image) 201 of the subject 10 and an enlarged image 202 of the peripheral region of the subject 10 eye. Although the example has been described, the display between the face image 201 and the enlarged image 202 may be switched. As a result, the enlarged image 202 of the peripheral area of the eye of the subject 10 can be displayed on the entire display of the display unit 104, and the eye open state of the subject 10 can be further visually recognized.

  The marker 203 may be switched between display / non-display every predetermined time (for example, 2 seconds), or may be instructed to switch display / non-display of the marker 203 via the instruction receiving unit 105. . By making the marker 203 non-displayed, it becomes easier to visually recognize the eye-opened state of the subject 10.

  In the above embodiment, the detection unit 103 sets a rectangular area of a predetermined size including the eyes of the subject 10 and notifies the display unit 104 of the vertex position of the rectangular area. The image data itself corresponding to the rectangular area may be output to the display unit 104.
