Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an iris.
When confirming the person using, when there are multiple targets,
The present invention relates to an identification method and an identification device for identifying an object to be identified for which an iris is to be obtained from a plurality of objects.

[0002]

2. Description of the Related Art Conventionally, a technique using an iris (iris) has attracted attention in order to identify the person. As a disclosure of such personal identification technology, for example, Japanese Patent Publication No. 5-8416
"Iris recognition system" described in Japanese Patent No. 6 publication, Kaikaihei 3
"Personal identification device" described in Japanese Patent Laid-Open No. 101911.

The iris will be briefly described here. The pattern of the surface layer of the human eyeball, particularly the iris, is
It is formed by a pattern with radial black stripes and outer contours centering on the crystalline lens, and this pattern is completed in childhood, and even if it is the same person for each individual It's different. Therefore, when this iris is used, the ability to confirm the identity is particularly excellent.

Since the iris is visible on the surface of the eyeball, it is possible to illuminate the iris to make it brighter, and to capture the iris from a distance using a camera. It has the feature that it is unnecessary and hassle-free.

As a means of capturing an iris from a distance using a camera, a "human body" is identified from an image captured by the camera, a "face" is extracted from the identified "human body", and then " The position of the "eye" is specified. Then, the iris of the "eye" is caught, only the iris pattern is taken in, and the iris data of the person who is registered in advance is collated to confirm the person.

As an apparatus having the above-mentioned functions, there is an automatic transaction apparatus installed in, for example, a financial institution. In such an automatic transaction apparatus, for example, an iris is used to confirm whether or not the customer who has inserted the ID card into the automatic transaction apparatus is the person who should own the ID card.

In such an automatic transaction device, the camera for catching the iris is in a state in which the lens is oriented toward the ceiling in the vicinity of the display portion provided in the central portion of the device operated by the person to be identified who is the object to be identified. It is provided in. Note that the reason why the lens is directed toward the ceiling is to fix the background. Then, by the operation of the person to be identified looking at the display unit, the person to be identified is identified from the image acquired from the lens of the camera, and then the iris of the person to be identified looking at the display unit is illuminated and caught. .

In the conventional apparatus, since the camera is installed in a substantially central portion of the apparatus in a state of being inclined toward the ceiling, the illumination for illuminating the iris must be installed in a state of being inclined like the camera. I have to do it. Therefore, there is a problem that it is more difficult to install than a flat installation.

Further, if the camera and the illumination are installed in the substantially central part of the device, there is a problem that it interferes with the display part. Furthermore, the camera is facing the ceiling,
That is, since the lens is installed with the lens facing upward, there is a problem that dirt easily adheres.

Therefore, in order to solve the above-mentioned problems, the camera is installed at a position where the camera is capable of capturing the person to be identified with the person to be identified facing straight forward (hereinafter, such a state is assumed to be horizontal). It was necessary to install the camera horizontally above the device as described above.

[0011]

In the above-mentioned conventional apparatus, when the camera is installed horizontally in the apparatus so that the lens is in the horizontal state, the background is not the ceiling but the front of the apparatus. Therefore, not only the person to be identified who should obtain the iris at that time, but also the other persons to be identified in the vicinity of the person to be identified and the vehicle running outside are displayed on the camera. Therefore, there is a problem that it is impossible for the device to recognize which iris should be acquired.

[0012]

[Means for Solving the Problems] The solving means provided by the present invention for solving the above-mentioned problems is provided by a plurality of objects displayed on a camera.
In the identification method for identifying the object to be identified from among
Based on the motion of the
Therefore, the operation instructions for the identification target are
So that the predetermined operation is performed on the object to be identified.
The object to be identified that gives the operation instruction and moves according to the instruction

By comparing with the direction, it is determined that the target is the identification target .

First, an instruction to perform a predetermined operation is given to the object to be identified. Then, the object to be identified performs the operation, but other objects imaged with the camera do not perform the instructed operation. Therefore, among the plurality of objects displayed on the camera, the object that has performed the designated predetermined operation is determined to be the identification target.

Has a storage unit 21 for storing the account number of each customer, deposit and savings balance information, data relating to iris, and the like.

Next, a function as an identification device for identifying a person to be identified from a plurality of moving objects will be described. FIG. 4 is an explanatory view showing a table 1a according to the first embodiment of the present invention, FIG. 5 is an explanatory view showing a table 1b according to the first embodiment of the present invention, and FIG. It is explanatory drawing which shows the table 2 in 1st Embodiment. Incidentally, in the tables 1a and 1b, the arrow indicates that there is no movement as compared with one second before.

In FIG. 2, when the person to be identified, which is the object A, approaches the automatic transaction apparatus 2 prior to the transaction, the approach detector 18 indicates that the person to be identified is within the predetermined range of the automatic transaction apparatus 2. Is notified to the main control unit 11. In response to the signal, the main controller 11 starts the operation of acquiring the iris of the person to be identified via the camera 14.

The image processing unit 12 has a function of dividing the pixels of the image captured by the camera 14 into blocks of four pixels in this case. Then, the image processing unit 12 stores the position of the block for every four pixels, and performs pattern matching with each of the surrounding blocks to detect the position of each block after Δt seconds. The point with the smallest movement value is the destination. In this way, the main control unit 11 can recognize the movement direction and the movement distance of all the moved objects.

Next, the storage unit 16 will be described. The storage unit 16 is provided with a table 1 and a table 2. The table 1 which is a movement direction storage unit is composed of a table 1a shown in FIG. 4 and a table 1b shown in FIG. For each moving object captured by the camera 14, the table 1a shows the moving direction detected by the above-described operation direction and operation distance detection method from the time when the proximity sensor 18 detects the object for a predetermined time (main In the embodiment, it is stored as data in the direction of sequential movement every 1 second). Table 1
In b, for each moving object captured by the camera 14, the operation direction and the moving direction detected by the operation distance detection method are given for a predetermined time from the time when an operation instruction (upward, for example) is given to the person to be identified. It is stored as data in the direction in which the movement is sequentially performed for a fixed time (4 seconds in the present embodiment) every (1 second in the present embodiment).

In the table 2 which is a fixed storage unit, the direction in which the person to be identified is supposed to move when inserting a card, the direction in which the person to be identified is supposed to move when inserting a passbook, and the camera 14 are shown. The direction in which the person to be identified is supposed to move when looking is stored, and when the person to be identified performs an input operation from the display unit 8, the main control unit 11 reads from the table 2 based on the input information. Call the required direction of the identified person. Then, the movement of the object photographed by the camera 14 is compared with the direction in which the person to be identified called from the table 2 is to move, and the person to be identified is specified from among the plurality of moving objects. That is, a plurality of objects and the person to be identified are identified.

The main control unit 11 recognizes by the input operation from the display unit 8 by the person to be identified that the person to be identified wants to perform processing from depositing, withdrawal, bookkeeping, balance confirmation, and the like. There is. Therefore, the main controller 11 stores the data in the memory 16 in the table.
The data of the motion direction of the person to be identified in the selected process is selected from the bull 2. Then, the data and the table 1a or the table 1 in the movement direction of the selected person to be identified.
Compared with the data of the moving direction of the object stored in b, the object moved in the direction corresponding to the intended moving direction of the identified person called from table 2 is identified. Determined to be the person who should acquire the iris.

When the main control unit 11 discriminates the person to be discriminated from another object, the main control unit 11 switches to the iris acquisition operation of the person to be discriminated.

On the other hand, the direction in which the person to be identified is to move and the
If the moving direction of the object stored in the table 1a or the table 1b does not match, the main control unit 11
Instructs the next operation to perform the next process for identifying the person to be identified.

Next, an operation for distinguishing a plurality of objects (object B, a vehicle running outside, etc.) and a person to be identified (object A) in the automatic transaction device 2 having the above-mentioned configuration will be described.
FIG. 7 is an explanatory diagram showing the positional relationship between the camera and the object in the first embodiment of the present invention, and FIG. 8 is an explanatory diagram showing the object shown in the camera in the first embodiment of the present invention.

In the present embodiment, as shown in FIG. 7, the two objects come in vertically at substantially the same time, and the object B is arranged behind the object A standing in front of the automatic transaction device 2 first. Object A performs a deposit transaction, and even in the case of a deposit transaction, the operation of performing the iris acquisition operation to confirm the identity of the person to be identified FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 7 and 8, a description will be given according to the flowchart shown in FIG. FIG. 1 is a flowchart showing a procedure for identifying a person to be identified in the first embodiment of the present invention.

Since the camera 14 is installed horizontally above the automatic transaction device 2, the camera 14 captures the images of both the target A and the target B side by side, as shown in FIG. In this state, it is impossible to determine which iris to acquire if not only the target A who is the person to be identified but also the target B is moving, and therefore it is impossible to cut out and capture only the target A.

Therefore, the main control section 11 always determines whether or not the approach detector 18 has caught any object in step S1, and if an object to be identified is detected, the process proceeds to step S2.
In step S2, the main control unit 11 starts acquisition of an image by the camera 14, and starts storage processing of the acquired image. In step S3, when the identified person recognizes from the display section 8 that the identified person desires a withdrawal transaction, the main control section 11 gives an instruction to perform a predetermined operation. In this case, the predetermined operation is an operation of the apparatus, so that the ID card is inserted into the card insertion return port 4a of the card processing unit 4 on the display unit 8 and the passbook is inserted into the passbook insertion return port 5a. Show to insert into. In addition,
At the time of deposit transaction, if either the ID card or the passbook is inserted into the automatic transaction device 2, the transaction becomes possible.

At step S4, the main control section 11 determines the ID card.
If the card is inserted, the process proceeds to step S6, and if “NO”, the process proceeds to step S5. Steps S4 to S5
If the process proceeds to step S5, the main control unit 11 determines whether the passbook is inserted in step S5. If the passbook is not inserted after a predetermined time has elapsed, the transaction is aborted and the process ends.

When the process proceeds from step S4 to step S6, the main controller 11 performs the first identification process in step S6. As a result, if the person to be identified can be identified from the plurality of objects in step S7, the process ends.
If “NO”, the process proceeds to step S8, and in step S8, the main control unit 11 displays on the display unit 8 that the camera 14 is viewed,
The person to be identified is caused to perform an operation of looking at the camera 14. And
The storage process of the acquired image is started.

In step S9, the main control unit 11 performs the second identification process. In step S10, the main control unit 11 ends the process if the person to be identified can be identified from the plurality of objects. If "no", the process proceeds to step S11. In step S11, the main control unit 11 determines that there is an identification error, and proceeds to another operation for acquiring an iris such as having the person to be identified look further at the camera 14.

Next, the process of acquiring an image with the camera 14 and storing the image in the above steps (steps S2 and S8) and the identification process performed twice will be described. First, the process of acquiring an image with the camera 14 and storing the image in the table 1a (step S2) will be described with reference to FIG. 4 according to the flowchart shown in FIG. FIG. 9 is a flow chart showing a storage procedure in the first embodiment of the present invention.

In step S21, the main controller 11 sets the camera 1
When 4 acquires the image, the moving direction of the object in the image is divided for each object and stored in the table 1a. If one second has passed since the main control unit 11 started storing in the table 1a in step S22, the process proceeds to step S23. In step S23, the main control unit 11 determines whether or not the action to be performed by the person to be identified is performed. If it is performed, this process ends, and if "not", the process returns to step S21. In this case, the operation performed by the person to be identified is the insertion of an ID card or passbook. The operations from step S21 to step S23 are repeated until the ID card or passbook is inserted, and the moving direction for each object is continuously stored in the table 1a every one second.

Next, from step S21 to step S2
Regarding the first identification processing (step S6) after the processing up to 3 is completed, here, the case where the ID card is inserted from the card insertion return port 3a is referred to with reference to FIGS. 4 and 10. explain. FIG. 10 is an explanatory diagram showing the movement of the object reflected on the camera according to the first embodiment of the present invention. When the ID card is inserted, the main control unit 11 inserts the ID card shown in FIGS. 4 and 10 (here, 11 seconds after the camera 14 starts image acquisition). It is stored in the table 1 from the time when the ID card is inserted) to a predetermined time (here, the predetermined time is 4 seconds. Therefore, in this case, 7 seconds) to the time when the ID card is inserted. Call the direction of movement of the target. Next table 2
To call the operation direction of the person to be identified when the card is inserted into the card insertion return port 3a.

Then, the contents stored in the table 1a are searched for that match the movement direction of the person to be identified stored in the table 2. Here, since the card insertion / return port 3a is on the left side as viewed from the automatic transaction device 2, it is stored in the item of the card of the table 2 as "move leftward". Therefore, "it was moving to the left" in table 1 for the last 4 seconds from the time when the insertion of the ID card was detected.
The main control unit 11 determines that the object stored as
Judge. Here, the object A is moving to the left for 4 seconds, and the object B is not moving to the left. Therefore, subject A
The main control unit 11 determines that the person is a person to be identified.

If there are two or more objects "moved to the left" in the preceding 4 seconds from the time when the insertion of the ID card is detected, the time "moved to the left" is 4 times. The main control unit 11 determines that the object close to the second is the person to be identified.

Further, here, there are two or more objects "moved to the left" in the preceding 4 seconds from the time when the insertion of the ID card is detected, and the time "moved to the left" is set. If the same is true, or if there is no target "moved to the left", the main control unit 11 determines that the person to be identified cannot be identified.

Even when the ID card is a passbook, the processing is the same as that of the ID card except that the moving direction of the person to be identified is changed.

When the person to be identified cannot be identified in the first identification process, the second identification process is performed. FIG. 11 is an explanatory diagram showing the movement of the object reflected on the camera according to the first embodiment of the present invention.

Before the second identification process, in step S8,
As shown in FIG. 11, the object captured by the camera 14 by the above-described operation direction and operation distance detection method every 1 second for a predetermined time (4 seconds in this case) after instructing the person to be viewed to the camera 14. The moving direction of is stored in the table 1b shown in FIG. 4 for each object.

When 4 seconds have elapsed, the second identification process (step S9) is started, and the main control unit 11 calls the direction in which the object has moved for 4 seconds from the table 1b. Next
The motion direction of the person to be identified when looking at the camera 14 from the bull 2 is called. Then, the contents stored in the table 1b are searched for that match the movement direction of the person to be identified stored in the table 2. Here, since the camera 14 is above the automatic transaction device 2 and the person to be identified is facing down in order to see the display section 8 which displays the instruction, the camera item stored in the table 2 is described. Is "moving upward". Therefore, the main control unit 2 determines that the object stored in the table 1b as "moved in the upward direction" is the person to be identified for 4 seconds after the instruction to look at the camera 14 is given. . Here, the target A moves upward for 3 seconds, and the target B moves.
Is not moving upwards. Therefore, the main control unit 11 determines that the target A is the person to be identified.

If there are two or more objects “moved upward” within 4 seconds after the instruction to look at the camera 14, the time “moved upward” is closer to 4 seconds. The main control unit 11 determines that the person is a person to be identified.

Further, here, the object "moved in the upward direction" is 2 within 4 seconds after the instruction to look at the camera 14 is given.
The main control unit 11 determines that the person to be identified cannot be identified if there is one or more and the time of “moving upward” is the same, or if there is no “moving upward”.

Then, in the flow chart shown in FIG. 1, when the person to be identified is specified and the processing is completed, the image data relating to the objects other than the person to be identified are erased, and subsequently the person to be identified. The iris acquisition operation is proceeded to, and it is judged whether or not there is an iris registered in the host computer 20 and an iris acquired from the person to be identified. If they match, a deposit process is performed.

In the first embodiment, the camera can be installed in a horizontal state, so that even if a plurality of cameras 14 image an object, the iris of the person to be identified can be acquired. Become.

Further, when identifying a person to be identified from a plurality of objects, the person to be identified is caused to perform an action, but in order to encourage the action, a new function is not provided, but it is originally automatic. The person to be identified is caused to perform an operation using the function of the transaction apparatus 2. Further, by using two cameras 14, it is possible to distinguish the person to be identified from the background, but in the present embodiment, only one camera 14 can distinguish the person to be identified from the background. Therefore, it is not necessary to provide a function for promoting the operation, and a new camera need not be installed. As a result, the cost of the function for identifying the person to be identified is low.

Further, the moving distances for each second are stored in the table 1a and the table 1b together with the moving direction, and the table 2 is a reference for performing the moving direction together with the moving direction. If the movement distance is stored in advance, even if a plurality of objects move in the same direction for the same time, if the movement distance is different, it is possible to identify the person to be identified from the difference in the movement distance. The identification efficiency is improved.

Further, depending on the person to be identified, the ID card may be inserted into the card insertion return port 3a before the transaction type is input from the display section 8. Even in this case, since the moving direction of the object is sequentially stored in the table 1a from the time when the proximity detector 18 detects the object to be identified, it is possible to specify the person to be identified.

Further, as shown in the above embodiment, even when it is considered that the person to be identified performs two operations (ID card insertion, passbook insertion), the proximity detector 18 is Since the moving direction of the object is sequentially stored in the table 1a from the time when the object to be identified is detected, the device knows which of the two operations the identified person performs until the time when the operation is performed. Even if it is not, it is possible to identify the person to be identified.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to the drawings. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. FIG. 12 is a block diagram showing a control system of the automatic transaction device in the second embodiment of the present invention, and FIG. 13 is an explanatory diagram showing a focusable range in the second embodiment of the present invention. This embodiment is different from the first embodiment in that it is set so that the iris of the focused object is acquired earliest in the image acquired by the camera 27, and the person to be identified first receives the camera 27. This is because the camera 27 can obtain the iris of the person to be identified by making the focus of the.

More specifically, in FIG. 12, the camera 27 has a diaphragm 22 for changing the depth of a subject that can be focused, a CCD sensor 23 connected to the camera control unit 29 for capturing an image, and a diaphragm 22. A lens 28 that is movable between the CCD sensor 23 and the CCD sensor 23 is provided.

The main controller 24 is connected to the image processor 30 and the camera controller 29, and the camera 27 is connected to the camera controller 29. Camera control unit 29 and camera 2
7 is connected by two lines, a line for transmitting image data and a line for transmitting control signals.

Then, the camera control unit 29 has a diaphragm 22.
Is in the maximum open state, and the lens 28 is moved from the position closest to the CCD sensor 23 to the maximum CCD sensor 2
The range in which the acquired image is in focus when moved to a position away from 3 (focusable range C shown in FIG. 13) is set in advance.

In the camera 27, the focusable range in the state where the diaphragm 22 is opened to the maximum is the range in which the object A to be identified and the object B behind it are included. That is, when the camera control unit 29 opens the diaphragm 22 to the maximum extent, it is possible to focus only the object (two people in this case) near the automated teller machine 2 when the lens 28 is moved. It is like this. The image acquired by the CCD sensor 23 is transmitted to the camera control unit 29 as numerical image data.

The moving range of the lens 28 is divided into N pieces in advance, and the lens 28 is located at a position as close as possible to the CCD sensor 23 at first. However, by the control of the camera controller 29, the person to be identified is (1 / N) at a time. Move in the direction, ie CC
It moves in a direction away from the D sensor 23 (direction of arrow D). Here, as the lens 28 moves away from the CCD sensor 23, within a focusable range,
As seen from the camera 27, the focus gradually becomes farther. Therefore, the person to be identified closest to the automated teller machine 2 is focused first.

Next, the part for determining whether or not the camera 27 has acquired the person to be identified will be described. The image processing unit 30 includes a contour cutout unit 25 and an iris acquisition unit 26, which are connected to the main control unit 24, respectively.

The contour cutout section 25 is composed of a contour emphasis filter or the like, and cuts out the target contour. In the contour cutout unit 25, the number of pixels detected by the contour detection when the input image data is subjected to the contour detection in advance is set as a reference value, Each time 28 approaches the person to be identified, the reference value is compared with the value of the image data transmitted from the camera control unit 29. Then, when the value of the image data becomes higher than the reference value, it is determined that there is a focused object. As the lens 28 moves away from the CCD sensor 23, the focus gradually becomes farther from the camera 27. Therefore, the first focused object is the object closest to the automated teller machine 2. The identification target, that is, the person to be identified.

When the person to be identified is in focus and the person to be identified can be acquired, the iris acquisition unit 16 starts the iris acquisition operation of the person to be identified.

The other structure is similar to that of the first embodiment, and the description thereof is omitted. The tables 1a, 1b and the table 2 of the storage unit 16 provided in the first embodiment need not be provided in the storage unit 30 of the present embodiment.

Next, an operation for identifying a plurality of objects (object B, a vehicle running outside, etc.) and a person to be identified (object A) in the automatic transaction device 2 having the above-mentioned configuration will be described.

In the present embodiment, as shown in FIG. 7, the two objects come in vertically at substantially the same time, and the object B is lined up behind the object A standing in front of the automatic transaction device 2 first. Operation to identify a person to be identified while in a state
2 and FIG. 13, a description will be given according to the flowchart shown in FIG. FIG. 14 is a flowchart showing a procedure for identifying a person to be identified in the second embodiment of the present invention.

First, the diaphragm 22 is opened to the maximum extent, and the lens 28 is positioned at the position closest to the CCD sensor 23.

The main control section 24 always judges whether or not the approach detector 18 has caught any object in step S31, and if the object to be identified is detected, the process proceeds to step S32. In step S32, the main control unit 24 starts acquisition of an image by the camera 27, and transmits the acquired image as image data to the contour cutout unit 25 via the camera control unit 29. In step S33, the contour cutout unit 25 compares the preset reference value with the image data value transmitted from the camera control unit 29.
