  An object of the present invention is to provide an ID card update system that can easily and surely acquire a face image of a matching level without individual differences.

  In order to achieve the above object, an ID card update system of the present invention includes a reading unit that reads personal data recorded on an ID card before update, and the face of the owner of the ID card that reads the personal data by the reading unit. An image capturing unit that captures an image, a face image captured by the image capturing unit, and face image data before update of the owner included in the personal data read by the reading unit are collated, and based on the collation result, A determination unit that determines whether or not the photographed face image is suitable for an ID card, and the personal data of the owner is updated and recorded using the face image that is determined to be suitable by the determination unit And a card creation unit for creating a new ID card.

  The ID card update system of the present invention also includes a database storing personal data recorded on all issued ID cards, a photographing unit for photographing a face image of the owner of the ID card desired to be updated, and this photographing. The face image photographed in the department and the face image data included in the personal data of the ID card stored in the database when the ID card owned by the owner is issued, and based on the collation result, The personal data of the owner is updated and recorded using a determination unit that determines whether or not the captured face image is suitable for an ID card, and the face image that is determined to be compatible by the determination unit And a card creation unit for creating a new ID card.

  According to the above invention, the face image data before update and the photographed face image are collated to determine whether or not the photographed face image is suitable for an ID card. The face image data at the time of issuance of the ID card can be used as the data, and a determination can be made based on the face image adapted for the ID card at the previous update. For this reason, for example, even for a person who is likely to be determined to have closed eyes despite having open eyes, whether the eyes of the captured face image are open or not is Since it can be determined at the individual level using face image data that is suitable for use as a license, it is possible to more reliably and easily determine that the eyes are open, and a dictionary for providing a determination criterion is not required .

  Since the ID card update system of the present invention has the configuration and operation as described above, it is possible to easily and surely acquire a face image of a matching level without individual differences.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram illustrating a schematic configuration of a license update system 1 (hereinafter simply referred to as system 1) for updating a driver's license as an ID card update system according to an embodiment of the present invention. It is.

  The system 1 is embedded in the camera 2 (photographing unit) for photographing the face image of the owner P who plans to update the driver's license (ID card), the face image photographed by the camera 2, and the driver's license. Image display monitor 3 for displaying face image data read from the previous IC chip, other written data such as address and name, various data extracted from the database, address printed on issued driver's license A host server 4 that stores description data such as name and name in association with a license number (authentication data), and a filing server 5 that stores face image data of all owners taken at the time of the previous update in association with the license number, Reading unit 6 for reading the above-mentioned license number, description data, face image data, etc. recorded on the IC chip of the driver's license, and the owner's who updates the driver's license The image, name, address, etc. are printed on the surface of the driver's license, and the owner's face image data, license number, written data such as address and name, etc. are updated and recorded on the IC chip embedded in the driver's license. A new driver's license, a license generating unit 7 (card generating unit), and the above-described camera 2, image display monitor 3, host server 4, filing server 5, reading unit 6, and license generating unit 7 And a personal computer (PC) 8 that functions as a determination unit of the present invention.

  The host server 4 and filing server 5 described above function as a database of the present invention that stores personal data such as description data and face image data recorded on an IC chip as well as described in an issued driver's license. . Although not shown here, an input unit for inputting a license number may be connected to the PC 8 by a keyboard operation by an operator instead of or in addition to the reading unit 6.

FIG. 2 shows a flowchart for explaining the operation of updating the driver's license by the system 1.
When updating the driver's license, first, as shown in step 1, the PC 8 determines whether or not the driver's license before the update is set in the reading unit 6 by the operator. When the driver's license before the update is set in the reading unit 6 (step 1; YES), the PC 8 reads personal data from the IC chip of the driver's license via the reading unit 6 as shown in step 2. . The read personal data is displayed via the image display monitor 3. The personal data referred to here includes a license number of the driver's license, face image data of the owner at the time of the previous update, and description data such as the name and address of the owner. In particular, the face image data read from the driver's license in step 2 is suitable for the driver's license at the time of the previous update.

  Thereafter, the PC 8 searches the filing server 5 based on the license number read in step 2 and extracts the face image data of the owner of the corresponding driver license at the previous update as shown in step 3. The face image data extracted from the filing server 5 is also displayed via the image display monitor 3. This face image data is also adapted as a face image for a driver's license when updated last time. Then, the PC 8 collates the face image data read from the driver's license in step 2 with the face image data extracted from the filing server 5 in step 3 using a known face collation technique. It is determined whether the face image data match. In this way, by comparing the face image data read from the driver's license with the face image data extracted from the filing server 5, it can be determined whether or not the driver's license has been forged.

  At this time, the PC 8 searches the host server 4 based on the license number read in step 2 and extracts the description data when the driver's license was last updated as shown in step 5. This written data is also displayed via the image display monitor 3. Then, the PC 8 collates the description data read from the driver's license in step 2 with the description data extracted from the host server 4 in step 5, and determines whether the description data matches as shown in step 6. to decide.

  The PC 8 determines that the face image data match at step 4 and the description data match at step 6 (step 4; YES, step 6; YES), and the owner's license for updating the driver's license is determined. If the photographing of the face image is permitted, the PC 8 photographs the face image of the owner by the camera 2 as shown in step 7.

  On the other hand, when the PC 8 determines that the face image data does not match in step 4 (step 4; NO), or when the PC 8 determines that the written data does not match in step 6 (step 6; NO), the PC 8 An abnormality such as falsification of the personal data of the driver's license is determined, and error processing is performed as shown in step 8.

  In step 7, the PC 8 constantly rewrites and records shooting data for a certain time (for example, shooting data is recorded for several frames at intervals of 0.5 seconds), and an operator triggers shooting, that is, a shutter. The face image for the front 5 frames including the face image when is pressed is used. Then, as shown in step 10 and step 11, the PC 8 uses the eye information read from the face image data collated and matched in step 4 as a reference, and the face image of the first frame immediately after pressing the shutter in step 7 Determine if your eyes are open.

  At this time, the collated face image data that is a criterion for judgment is the face image data of the person who has been photographed by the owner of the driver's license at the time of the previous update and is suitable for the driver's license as being open. Therefore, even a person who is apt to be determined to close his / her eyes can make a determination based on the eyes information of the person himself / herself, and therefore can reliably and easily determine that the eyes are open. Thereby, even if it is determined that the conventional system is always closed and the driver's license cannot be automatically updated, the driver's license can be automatically updated with high probability.

  As a result of collating the face image of the first frame with the reference data as described above, when the PC 8 determines that the collation does not match, that is, the eyes are closed (step 11; YES), the face of the second frame before one The image is checked against reference data as shown in steps 10 and 11. Then, all the face images for 5 frames prepared in step 7 are collated with the reference data, and when the PC 8 determines that the face images of all 5 frames do not match the reference data (step 9; NO), the collation mismatch The face image of the first frame is displayed via the image display monitor 3 and, as shown in step 12, a warning that there is a mismatch is displayed. At this time, since the face image of the first frame is an image immediately after the shutter is pressed, the face image of the first frame is displayed with the highest possibility of opening the eyes.

  On the other hand, if it is determined that the eyes of the face image photographed in step 11 are open (step 11; NO), the PC 8 together with the data of the face image determined to be open as shown in step 13 The description data matched in step 6 is sent to the license creation unit 7. The license creation unit 7 prints the face image and description data sent from the PC 8 on the surface of the license, updates the face image data and description data on the IC chip, and issues a new driver's license.

  Then, the PC 8 continues the update process of Steps 1 to 13 until there is no driver's license scheduled for the update process (Step 14; NO), and ends the process when there is no driver's license to perform the update process. .

  As described above, according to the present embodiment, the reading unit 6 reads the license number from the IC chip of the driver's license before being updated, and extracts the face image data of the person at the time of the previous update in the filing server 5. The face image of the person photographed by the camera 2 is collated with reference to the face image data, and it is determined whether or not the eyes are open. As described above, since it is determined whether or not the eyes of the face image photographed based on the face image data of the person who is suitable for the license at the time of the previous update is open, it is important that the eyes are firmly open. Even if a person is apt to be judged as having closed eyes, the eyes are compared with the case where the eyes are opened using a dictionary that is compatible with all people as in the past. It can be easily and reliably determined to be open with high probability.

  In addition, according to the present embodiment, the license number is read from the IC chip of the driver's license before being updated via the reading unit 6 and the face image data at the time of the previous update is extracted. It is not necessary to read the license number by using, and the cost of the entire system can be reduced. Although the license number can be input using the input unit instead of the reading unit 6, the PC 8 searches the filing server 5 based on the input license number and extracts face image data. It will be.
