Thereafter, the individual identification system 100 proceeds to step S805.

  In step S805, the individual identification system 100 identifies an individual using the individual identification device 10 (identification step). At this time, the individual identification device 10 identifies the individual in the same manner as the operation of the individual identification device 10 according to the embodiment (step S504 to step S507 in FIG. 5). Thereafter, the individual identification system 100 proceeds to step S806.

  In step S806, the individual identification system 100 uses the input unit 101 to input an identification result from the individual identification device 10 to the information terminal 100T (input step).

Thereafter, the individual identification system 100 proceeds to step S808.

  In step S808, the individual identification system 100 determines whether to repeat the operation of identifying an individual using the information terminal 100T. Specifically, the information terminal 100T determines whether to change the identification target information output from the information terminal 100T and repeat the operations from step S803 to step S807. For example, the information terminal 100T can determine whether or not to repeat the operation of identifying the individual based on information input from the user of the information terminal 100T. Thereby, the individual identification system 100 can identify an individual at a timing desired by the user of the information terminal 100T.

  Thereafter, when it is determined that the operation of identifying the individual is repeated, the individual identification system 100 returns to Step S803. If it is determined that the operation for identifying the individual is to be terminated, the individual identification system 100 proceeds to “END” in the figure, and terminates the operation for identifying the individual.

FIG. 11 is a diagram illustrating an example of identification target information (intraoral X-ray image data at the time of panoramic imaging) acquired by the individual identification device according to the present invention. FIG. 12 is an explanatory diagram for explaining an example of collation processing of contour data (particularly left contour data) of identification target information (intraoral X-ray image data at the time of panoramic imaging) acquired by the individual identification device according to the present invention. is there. FIG. 13 is a diagram illustrating an example of identification target information (tooth treatment information) acquired by the individual identification device according to the present invention. The identification target information shown in FIGS. 9 to 13 is an example, and the identification target information acquired by the individual identification device according to the present invention is not limited to the identification target information shown in FIGS. 9 to 13.

  As shown in FIG. 9A, the individual identification device 10 can use head X-ray image data from the front as identification target information. Moreover, as shown in FIG.9 (b), the individual identification apparatus 10 can utilize the head X-ray image data from the side as identification object information. As shown in FIG. 10A, the individual identification device 10 can use hard tissue X-ray image data as identification target information. Moreover, as shown in FIG.10 (b), the individual identification device 10 can utilize the X-ray image data of the hard tissue of a foot | leg as identification object information.

  The individual identification device 10 includes, as identification target information, the skull outline, the eye socket, the maxillary anterior part, the maxillary molar part, the maxillary sinus floor line, the mandibular molar, the mandibular anterior part, the mandibular outline, the mandibular canal, and the vicinity of the root. Any one or a plurality of shapes of the alveolar hard line and cheekbone can be collated. In addition, the individual identification device 10 uses, as identification target information, any one of the distance between the lower edge outline of the mandibular bone body part and the mandibular canal, the root curvature state of the mandibular molar part, and the pattern based on the bone density of the mandible. Or it can collate on the basis of two or more.

  As shown in FIG. 11, the individual identification device 10 can use intraoral X-ray image data during panoramic imaging as identification target information. Here, as shown in FIG. 12A, in the intraoral X-ray image data at the time of panoramic imaging, there are two substantially arc-shaped protrusions on the distal side of the contour data (left side in the figure). . The individual identification device 10 draws a common tangent line to the two protrusions as shown in FIG. Further, as shown in FIG. 12B, the individual identification device 10 can collate identification target information (image data) and collation information (image data) using the tangent line as a reference line. Thereby, the individual identification device 10 can determine whether or not the shapes of the mandibular branch centrifugal lines are matched.

  For example, the individual identification device 10 can perform collation based on whether or not the size of the non-overlapping portion of the mandibular branch centrifugal line and the contrast ratio are equal to or less than a predetermined reference value. The contrast ratio is, for example, the ratio between the area of the non-overlapping part and the area of the overlapping part. Further, the individual identification device 10 can collate based on whether the lengths of the tangent lines of the identification target information (image data) and the collation information (image data) are the same. It should be noted that tangents are used only when collating the mandibular centrifuge line, and other methods may be used. For example, the shape of the cranial centrifuge line itself is matched as in fingerprint collation. You may do it. The predetermined reference value is a value corresponding to a bone part to be identified. In addition, the individual identification device 10 according to the present invention can set the predetermined reference value to a value determined in advance by experiment or calculation.

  As illustrated in FIG. 13, the individual identification device 10 can use dental treatment information as identification target information. The individual identification device 10 targets a total of twelve teeth, for example, upper, lower, left, and right canines, first molars, and second molars as tooth treatment information. The individual identification device 10 defines a total of eight items of treatment information to which numbers 0 to 7 are assigned as tooth treatment information. Here, the items are, for example, “0: deficit”, “1: no metal / no fullness”, “2: no metal, no fullness”, “3: with metal / no fullness”, “4: with metal / fullness” “Yes”, “5: Impacted tooth”, “6: Hemisection (only the lower jaw)”, “7: Pontic”, and “8: Implant” can be used.

  The individual identification device 10 sets “1” as identification target information for each tooth when it corresponds to the prescribed treatment information and “0” when it does not correspond. The healthy tooth corresponds to the above-mentioned “1: no metal and no fullness”. Note that the presence of metal can be most easily confirmed in an X-ray image. In addition, since restoration materials and prosthetic materials other than metal appear in various concentrations due to differences in X-ray transmission on X-ray images, there is a high possibility that findings will be divided by doctors. If an X-ray opacity image can be confirmed in the root canal, the presence or absence of root filling can be determined as “root filling”, thereby unifying the doctor's findings.

“6: Hemi section” is divided tooth extraction. In this example, the identification target information includes only the lower molar that can be easily confirmed because it may be difficult to discriminate the upper forehead molar, but it may be an upper forehead molar. Hemisection is a treatment for molars. In this example, since only the lower jaw teeth are targeted, the input of “7: hemisection” may not be accepted for the canine teeth and the upper jaw teeth. The individual identification device 10 according to the present invention may target canine teeth and maxillary teeth as identification target information.

Example 4

  An example of a biometric authentication system including the individual identification device 10 according to the embodiment will be described.

  The system of the biometric authentication system which concerns on Example 4 of this invention is demonstrated using FIG. Here, FIG. 18 is a schematic system configuration diagram illustrating an example of a biometric authentication system according to the present embodiment. In the following description, parts different from the individual identification device 10 according to the embodiment and the individual identification system 100 according to Example 3 will be mainly described.

  As illustrated in FIG. 18, the biometric authentication system according to the present embodiment includes a face authentication device CM, a beam irradiation device BM, and a beam detection device SN. Note that the beam irradiated by the beam irradiation device BM may be one or more of X-rays, ultrasonic waves, electromagnetic waves, and / or light emission.

  The imaging of the skull is divided into a planar image and a 3D image. In the case of a planar image, for example, the skull is imaged from the side. Many holes exist in the skull, but the images are relatively clear except for soft tissues (tissues other than bone), and are easy to analyze with a computer. The biometric authentication system can acquire, for example, an image of the head side surface shown in FIG.

  As shown in FIG. 18, the biometric authentication system uses a beam irradiation device BM to irradiate a beam that passes through the soft tissue from the side surface of the head. At this time, the biometric authentication system uses an image from the reference direction with reference to an irradiation angle at which the left and right outer ear holes (EH in FIG. 19) coincide with each other at the maximum. The biometric authentication system may be one in which the photographing apparatus can move to the reference axis. An image taken in this direction is a single image and has excellent reproducibility. The biometric authentication system can determine the median plane of the skull according to the direction in which the outer ear holes coincide with each other in conjunction with the face authentication device.

  When the person is facing upward or downward, the biometric authentication system uses the line (Frankfurt plane) FL connecting the lower edge of the orbit IB and the upper edge of the ear canal EH shown in FIG. (Direction of rotation) can be corrected. Thereby, since the biometric authentication system can set the position of the skull, the position of the mandible can be set by the instruction of the bite state.

  As described above, the biometric authentication system can perform biometric authentication using the image acquired by the beam detection device SN.

  In addition, as a part that is not easy to disguise, the root of the tooth is curved, the alveolar hard line that is different from other bones due to high calcification around the root, the line from the joint process behind the mandibular mandibular branch to the mandibular angle, lower There are inferior alveolar tubes etc. present in the jawbone Also in this case, the position for the above-described imaging is determined, the beam is irradiated from the front slightly to the skull using the beam irradiation device BM, and the mandibular mandibular branch on the detection side is detected using the beam detection device SN. You can shoot. Further, the biometric authentication system may be configured to further use a dental panoramic X-ray photograph.

In the case of using a 3D image, the biometric authentication system can determine the position of the head (subject) using the face authentication device CM (FIG. 18). The biometric authentication system may detect the direction of the skull, move the 3D imaging apparatus to a desired position, and perform imaging. Furthermore, the biometric authentication system may match the image acquired by the present system with the 3D video by a conventional technique (phase correlation method or the like).
(Example 5)

  An example of identification target information (identification part of a hand part) acquired by the individual identification device according to the present invention will be described with reference to FIG. Here, FIG. 20 is a diagram illustrating an example of a hand as a part to be identified and authenticated (identification part) as identification target information acquired by the individual identification device according to the present invention.

  As shown in FIG. 20, in the biometric authentication (identification) from the image of the hand bone, the boundary between the carpal bone GA and the metacarpal bone GB may become unclear. For this reason, more accurate authentication is possible by performing authentication based on the shape of the phalanges GC located in the first to fifth periphery. As shown in FIG. 20, for example, the length in a 3D image or a planar image of the distal phalanx GC1, the middle phalanx GC2, and the proximal phalanx GC3 of the phalange GC may be used.

In the biometric authentication system, the distal phalanx GC1, the middle phalanx GC2, and the proximal phalanx GC3 of the phalange GC are measured in advance, and when performing authentication, the distal phalanx GC1, the middle phalanx GC2, and the proximal phalanx of the hand are further included. The accuracy of authentication can be improved by using the shape of GC3. Note that the distal phalanx GC1, the middle phalanx GC2, and the proximal phalanx GC3 can measure 14 with one hand and can measure 28 with both hands. In addition, a planar image can be taken with a palm placed on a detector, and measured and authenticated by a two-dimensional length and shape. For a 3D image, authentication can be performed by calculating an accurate length from the 3D video and further matching the shape by the phase correlation method.

Here, FIG. 21 is a diagram illustrating an example of a foot as a part to be identified and authenticated (identification part) as identification target information acquired by the individual identification device according to the present invention.

  As shown in FIG. 21, in the biometric authentication (identification) from the image of the foot bone, the boundary between the tarsal bone FA and the metatarsal bone FB may be unclear. For this reason, by performing authentication based on the shape of the phalange FC in the first to fifth peripheral portions, more accurate authentication can be performed. As shown in FIG. 21, for example, the length in the 3D image or planar image of the distal phalanx FC1, the middle phalanx FC2, and the proximal phalanx FC3 of the phalange FC may be used.

  In the biometric authentication system, the distal phalanx FC1, the middle phalanx FC2, and the proximal phalanx FC3 of the phalange FC are measured in advance, and when the authentication is performed, the distal phalanx FC1, the middle phalanx FC2, and the proximal phalanx of the hand are further added. The accuracy of authentication can be improved by using the shape of FC3. The distal phalanx FC1, the middle phalanx FC2, and the proximal phalanx FC3 can measure 14 with one hand and can measure 28 with both hands. In addition, a planar image can be photographed with a foot on a detector, and measured and authenticated by a two-dimensional length and shape. For a 3D image, authentication can be performed by calculating an accurate length from the 3D video and further matching the shape by the phase correlation method. Furthermore, the phalanges of the toe can be recognized even by standing on the detector or walking on the detector.
