The sensor unit 20 includes a guide 21 that guides the user's palm to a normal position and a sensor 30 that acquires a vein image (biological information) of the palm. The sensor unit 20 can handle both the left hand and the right hand, but here, the palm of the left hand will be described as a biological information acquisition target, and will be described in the order of five fingers based on the left hand.

The guide 21 has a shape in which a box-shaped housing whose upper surface is opened is supported by a housing support portion 22 and a housing support portion 23 that serve as a base. The guide 21 includes a wrist support unit 25 that supports the wrist of the user, a three-finger support unit 50 that supports the three fingers of the second finger (index finger), the third finger (middle finger), and the fourth finger (ring finger), A first finger / fifth finger support unit 24 that supports one finger (thumbnail), fifth finger (little finger), thumbnail or little finger hill is provided.

The first finger / fifth finger support portion 24 is a concave shape formed of a curved surface, and can support the first finger or the fifth finger including the thumb hill or the little finger hill.

The three-finger support unit 50 includes a three-finger placement surface 56 for placing and supporting three fingers of the second finger, the third finger, and the fourth finger, and the three fingers of the second finger, the third finger, and the fourth finger. Are provided with two finger crotch guides 53L and 53R.

The three-finger placement surface 56 has a pressure sensor 55L at a position corresponding to the finger pad of the fourth finger, a press sensor 55C at a position corresponding to the finger pad of the third finger, and a position corresponding to the finger pad of the second finger. Includes a pressure sensor 55R. The pressure sensor 55L detects the pressure with which the fourth finger is placed on the three-finger placement surface 56. The pressure sensor 55 </ b> C detects the pressure with which the third finger is placed on the three-finger placement surface 56. The pressure sensor 55 </ b> R detects the pressure with which the second finger is placed on the three-finger placement surface 56. For example, the pressure sensor 55 (55L, 55C, 55R) can use a pressure sensitive element.

The finger crotch guide 53L contacts the finger crotch portion of the third finger and the fourth finger, guides the third finger and the fourth finger to the three-finger placement surface 56, and guides the front and rear positions of the palm. The finger crotch guide 53R contacts the finger crotch portion of the second finger and the third finger, guides the second finger and the third finger to the three-finger placement surface 56, and guides the front and rear positions of the palm.

The finger crotch guide 53L includes a pressure sensor 54L at a position where the finger crotch portion of the third finger and the fourth finger abut. The pressure sensor 54L detects a pressure at which the finger crotch portions of the third finger and the fourth finger contact the finger crotch guide 53L. The finger crotch guide 53R includes a pressure sensor 54R at a position where the finger crotch portion of the second finger and the third finger abut. The pressure sensor 54R detects a pressure at which the finger crotch portions of the second finger and the third finger contact the finger crotch guide 53R. For example, the pressure sensor 54 (54L, 54R) can use a pressure sensitive element.

The finger crotch guide 53 (53L, 53R) includes a finger separation rib 51 that separates each finger, and a finger side guide 52 that abuts the immediate part of each finger on both sides of the finger separation rib and guides each finger to a normal position. Prepare.
The sensor unit 20 includes a sensor 30 on the bottom surface of a box-shaped housing. The sensor 30 includes an image sensor (for example, a complementary metal oxide semiconductor (CMOS) sensor, a charge coupled device (CCD) sensor), a condenser lens, and a plurality of near infrared light emitting elements (LEDs) that irradiate a subject. : Light Emitting Diode).

Next, how the sensor unit 20 guides the user's palm to the normal position will be described with reference to FIG. FIG. 5 is a diagram illustrating an appearance when a hand is placed on the sensor unit of the first embodiment.

The sensor unit 20 guides the palm of the user's hand 2 to the normal position by the guide 21 and acquires a vein image of the palm. The user passes the finger crotch guide 53L between the third finger and the fourth finger, and passes the finger crotch guide 53R between the second finger and the third finger, so that the hand 2 moves in the left-right direction (along the left-right axis). Direction).

Further, the user abuts the finger crotch portion of the third finger and the fourth finger on the finger crotch guide 53L with an appropriate pressure, and the finger crotch portion of the second finger and the third finger on the finger crotch guide 53R. Is brought into contact with the front and rear in the front-rear direction (the direction along the front-rear axis). For example, when the pressure with which the finger crotch portion comes into contact with the finger crotch guide 53 is too small, it can be estimated that the hand 2 is in an inappropriate position with respect to the finger crotch guide 53. When the pressure at which the finger crotch portion comes into contact with the finger crotch guide 53 is excessive, it can be estimated that the hand 2 is pressed too strongly against the finger crotch guide 53. In this case, when acquiring a vein image as biological information, the blood circulation of the hand 2 may be inhibited (congestion due to blood vessel pressing), and biological information may not be acquired appropriately. Or when acquiring a vein image as biometric information, the hand 2 may deform | transform and biometric information may not be acquired appropriately.

In addition, the user applies a pressure for bringing the third and fourth finger crotch portions into contact with the finger crotch guide 53L, and a pressure for bringing the second and third finger crotch portions into contact with the finger crotch guide 53R. By making them substantially the same, yawing (rotation on the vertical axis) is eliminated and the guide is guided to the normal position.

In addition, the user contacts the finger pad of the fourth finger with the pressure sensor 55L with an appropriate pressure, contacts the finger pad of the third finger with the pressure sensor 55C with an appropriate pressure, and presses the finger pad of the second finger. By contacting the sensor 55R with an appropriate pressure, pitching (rotation on the left and right axes) is eliminated and the sensor 55R is guided to the normal position. For example, when the pressure with which the finger pad portion of each finger comes into contact with the pressure sensor 55 is too small, it can be estimated that the hand 2 has the fingertip facing upward. When the pressure with which the finger pad portion of each finger comes into contact with the pressure sensor 55 is excessive, it can be estimated that the hand 2 has the fingertip pointing downward.

In addition, the user makes the rolling (on the front and rear axes) by making the pressure at which the finger pad portion of the fourth finger contacts the pressure sensor 55L and the pressure at which the finger pad portion of the second finger contacts the pressure sensor 55R are substantially the same. ) Is guided to the normal position.

Next, a configuration for the sensor unit 20 to guide the user's palm to the normal position and acquire a palm vein image will be described with reference to FIG. FIG. 6 is a diagram illustrating a configuration of the sensor unit according to the first embodiment.

The sensor unit (biological information acquisition device) 20 includes a sensing unit 60 and a guide unit (guide device) 70. The sensing unit 60 captures a vein image of the palm and transmits the captured data to the processing device 11. The sensing unit 60 includes a storage unit 61, a photographing unit 62, a control unit 63, and a communication unit 64.

The control unit 63 controls each processing unit in an integrated manner. The imaging unit (sensor 30) 62 acquires image information from a living body that is a subject. The storage unit 61 temporarily stores the image information acquired by the imaging unit 62. The communication unit 64 communicates with the processing device 11 and the guide unit 70.

The photographing unit 62 photographs near-infrared reflected light from a living body (palm) as a subject. Since hemoglobin in the red blood cells flowing in the veins has lost oxygen, this hemoglobin (reduced hemoglobin) has a property of absorbing near infrared rays in the vicinity of 700 nm to 1000 nm. Therefore, when near infrared rays are applied to the palm, only a portion where the vein is present is less reflected, and the position of the vein can be recognized by the intensity of reflected light of the near infrared ray. The photographed image by the photographing unit 62 is an achromatic image although it is easy to extract characteristic information by using a specific light source.

The guide unit 70 includes a communication unit 71, a control unit 72, press sensors 54L and 54R, press sensors 55L, 55C and 55R, LEDs 57L and 57R, and LEDs 58L, 58C and 58R.

The control unit 72 comprehensively controls each processing unit. The communication unit 71 communicates with the sensing unit 60. The pressure sensors 54 </ b> L and 54 </ b> R detect the pressure of the finger crotch portion that contacts the finger crotch guide 53. The pressure sensors 55L, 55C, 55R detect the pressure on the finger pad of each finger placed on the three-finger placement surface 56. The LED 57L notifies the magnitude of the pressure detected by the pressure sensor 54L in a display manner. The LED 57R notifies the magnitude of the pressure detected by the pressing sensor 54R in a display manner. The LED 58L notifies the magnitude of the pressure detected by the pressing sensor 55L in a display manner. The LED 58C notifies the magnitude of the pressure detected by the pressing sensor 55C in a display manner. The LED 58R notifies the magnitude of the pressure detected by the pressing sensor 55R in a display manner.

Next, a configuration for realizing processing for the registration apparatus 10 to perform template registration will be described with reference to FIG. FIG. 7 is a diagram illustrating a configuration of the registration apparatus according to the first embodiment. The registration device 10 includes a control unit 80, a storage unit 81, a notification unit 82, a communication unit 83, an image input unit 84, a feature amount evaluation unit 85, a reacquisition determination unit 86, and a template registration unit 87. Is provided.

The control unit 80 comprehensively controls each processing unit. The storage unit 81 stores and holds image information acquired from the sensor unit 20, various databases, and the like. The notification unit 82 generates a required display message such as guidance for the operation of holding the palm of the hand over the sensor unit 20 to the user, notification of success or failure of template registration, and displays the generated display message on the display 12. Further, the notification unit 82 generates a required voice message and outputs the voice from a speaker (not shown). The communication unit 83 performs communication with the sensor unit 20, communication with the IC chip built in the IC card reader / writer 15, and communication with other computers.

The image input unit 84 inputs a captured image of the living body from the sensor unit 20. More specifically, when the captured image is input, the image input unit 84 removes the background from the captured image and extracts the subject. The image input unit 84 determines whether or not the extracted subject is a palm. If it is determined that the subject is not a palm, the image input unit 84 again inputs a captured image of the living body from the sensor unit 20.

The feature amount evaluation unit 85 evaluates the feature amount included in the biological information from the captured image. Specifically, the feature amount evaluating unit 85 evaluates the vein pattern in the palm image or the amount of feature information included in the vein pattern. The feature information includes, for example, feature points (vein end points and branch points) included in the vein pattern, the number of veins connecting the feature points and neighboring feature points with a straight line, and a small image centered on the feature points. The amount of feature information is a value obtained by quantifying the number and quality of feature information using a predetermined evaluation algorithm. The greater the amount of feature information, the more stable the authentication accuracy, and the smaller the amount of feature information, the more unstable the authentication accuracy. As a simple example, the amount of feature information can be the number of feature points, or the total number of veins that intersect and intersect feature points and neighboring feature points. Note that the feature amount evaluation by the feature amount evaluation unit 85 may be an evaluation value (for example, a numerical value such as 100 or 200), or a feature amount evaluated by a predetermined threshold (for example, “multiple” , “Ordinary”, “low”, etc.).

The reacquisition determination unit 86 determines whether to reacquire biometric information based on the evaluation of the feature amount. The reacquisition determination unit 86 determines that reacquisition of biometric information, that is, re-input of a captured image, is performed when the evaluation of the feature amount is not sufficient for the acquired biometric information.

The template registration unit 87 processes the extracted image information as a registration template, and records (registers) the registration template in the storage unit of the processing device 11, the storage unit of the authentication server, or the storage unit of the user's IC card 16.

[Step S31] The guide unit 70 (control unit 72) acquires the outputs of the press sensors 54L and 54R and the press sensors 55L, 55C and 55R.
[Step S32] The guide unit 70 (control unit 72) refers to the press sensor output evaluation table 200 and acquires the posture evaluation of the user's hand 2 from the outputs of the press sensors 54L and 54R.

For example, if the pressing force detected by the pressure sensors 54L and 54R is within a preset range, it is evaluated as “appropriate”. If the detected pressing force is smaller than the set range, it is “weak”. ". More specifically, the guide unit 70 appropriately guides the hand 2 to the normal position by evaluating “appropriate” when the pressing force detected by the pressing sensors 54L and 54R is in the range of 200 g to 400 g. be able to.

When both the pressure sensors 54L and 54R are “weak”, the hand 2 is evaluated to be in the retracted position. When the pressure sensors 54L and 54R are both “suitable”, the hand 2 is evaluated to be in the normal position. When the pressure sensors 54L and 54R are both “strong”, the hand 2 is evaluated as being in an excessively advanced position. When the pressing force detected by the pressing sensor 54L is larger than the pressing force detected by the pressing sensor 54R, it is evaluated that the hand 2 is turning right (right rotation on the vertical axis) with respect to the vertical axis. When the pressing force detected by the pressing sensor 54R is larger than the pressing force detected by the pressing sensor 54L, it is evaluated that the hand 2 is turning leftward (left-rotating on the vertical axis) with respect to the vertical axis.

The guide unit 70 (control unit 72) refers to the press sensor output evaluation table 200, and the light emission mode of the LEDs 57L and 57R according to the evaluation of the press force of the press sensors 54L and 54R from the output of the press sensors 54L and 54R. To get.

For example, the light emission modes of the LEDs 57L and 57R are “green light emission” when the pressing force is evaluated as “appropriate”, “blue light emission” when the pressing force is evaluated as “weak”, and the pressing force is “strong”. When it is evaluated as “red light emission”.

Further, the guide unit 70 (the control unit 72) refers to the press sensor output evaluation table 210 and acquires the posture evaluation of the user's hand 2 from the outputs of the press sensors 55L, 55C, and 55R.
For example, if the pressing force detected by the pressure sensors 55L, 55C, and 55R is within a preset range, it is evaluated as “appropriate”, and “weak” when the detected pressing force is smaller than the set range, and when it is large. Rated as “strong”. More specifically, the guide unit 70 evaluates “appropriate” when the pressing force detected by the pressing sensors 55L, 55C, and 55R is in the range of 200 g to 400 g, so that the hand 2 is suitably placed in the normal position. I can guide you.

When both of the pressure sensors 55L and 55R are “weak”, or when both the pressure sensors 55L and 55R are “suitable” and the pressure sensor 55C is “weak”, the finger 2 of the hand 2 faces upward ( Rotation on the left and right axis). When both of the pressure sensors 55L and 55R are “strong”, or when both the pressure sensors 55L and 55R are “suitable” and the pressure sensor 55C is “strong”, the hand 2 has the fingertip facing downward ( Rotation on the left and right axis). When the pressure sensors 55L, 55C, and 55R are all “appropriate”, the hand 2 is evaluated to be in the normal position. When the pressing force detected by the pressing sensor 55L is larger than the pressing force detected by the pressing sensor 55R, it is evaluated that the hand 2 is rotating counterclockwise with respect to the front-rear axis. When the pressing force detected by the pressing sensor 55R is larger than the pressing force detected by the pressing sensor 55L, it is evaluated that the hand 2 is rotating clockwise with respect to the front-rear axis.

Further, the guide unit 70 (control unit 72) refers to the press sensor output evaluation table 210, and the light emission mode of the LEDs 57L and 57R according to the evaluation of the press force of the press sensors 54L and 54R from the output of the press sensors 54L and 54R. To get.

For example, the light emission modes of the LEDs 58L, 58C, and 58R are “green light emission” when the pressing force is evaluated as “appropriate”, “blue light emission” when the pressing force is evaluated as “weak”, and the pressing force is “ When it is evaluated as “strong”, it becomes “red light emission”.

The light emission modes of the LEDs 57L, 57R, LEDs 58L, 58C, 58R are “lit” when the pressing force is evaluated as “appropriate”, and “long-period flashing” when the pressing force is evaluated as “weak”. When the pressing force is evaluated as “strong”, “short cycle blinking” may be used.

[Step S33] The guide unit 70 (control unit 72) is a light emission mode of the LEDs 57L, 57R, LEDs 58L, 58C, 58R acquired with reference to the pressure sensor output evaluation tables 200, 210, and the LEDs 57L, 57R, LEDs 58L, 58C, The 58R output is displayed.

When both are in the normal position, the process proceeds to step S36, and when either one is not in the normal position, the process proceeds to step S35.

[Step S35] The guide unit 70 (control unit 72) proceeds to step S31 if it is within a predetermined time from the start of the determination in order to obtain the correct position evaluation of the user's hand 2, and the predetermined time has elapsed (time up). If so, the process proceeds to step S36.

[Step S36] The guide unit 70 (control unit 72) responds to the determination request from the sensing unit 60 as to whether or not the palm of the user is in the normal position, and ends the normal position determination process. In the guide unit 70 (control unit 72), both the evaluation (posture evaluation) acquired with reference to the press sensor output evaluation table 200 and the evaluation (posture evaluation) acquired with reference to the press sensor output evaluation table 210 are in the normal position. In some cases, a correct position response is performed. On the other hand, when the time is up in step S35, the guide unit 70 (control unit 72) responds with the evaluation (illegal position) acquired at the time up.
