 [Example]

Hereinafter, the present invention will be described in detail.

In the present invention, among the various wrist wearable devices such as a watch, a bracelet, a band, and a sports-type measuring device, a description will be given mainly on a watch mode which is considered to be able to best understand the spirit of the invention. Therefore, even though an example of a wrist wearable device having a clock shape is mentioned, it should be understood that the same applies to other various shapes of wrist wearable devices because the description can be sufficiently explained in the same manner. The various wrist wearable devices are basically equipped with a case for protecting electronic parts and a band for wrist wrapping.

In general, the vein recognition method utilizes the principle of acquiring and identifying the vein structure of the back of a hand. It mainly irradiates the infrared light to the back of the hand, photographs blood vessels, captures a characteristic of each vein pattern unique to each individual, The vein pattern of the subject is authenticated.

In order to achieve this, an image (hereinafter, referred to as a "hand-vein image") in which the vein and vein structure of the hand is photographed is necessarily required, and the vein image of the back of the hand must have sufficient quality to identify and recognize It is known that the vein image of the back of the hand is more clearly captured).

However, it is impossible to obtain a vein image in the wrist wearable device as a method for capturing the vein image of the hand in the conventional vein recognition.

FIG. 1 illustrates an example of a method of photographing a back vein image by a conventional vein recognition technique in a general wrist type wearable device according to an embodiment of the present invention.

FIG. 1 is a front view and a plan view of a scene in which a back vein image is photographed by a conventional method. As shown in FIG. 1, the conventional method includes infrared light for photographing and acquiring a vein image of the back of a wrist, It can be seen that the vein recognition can be performed only if the camera is present. Therefore, it can be seen that it is almost impossible to use an additional device outside the hand wearing the wearable wearable device in a wearable device sensitive to user convenience and wearability.

FIG. 2 illustrates an example of a method of photographing a vein of a hand by folding the wrist upward in a wrist wearable device capable of recognizing a vein according to an embodiment of the present invention.

As shown in FIG. 2, unlike the conventional method, it can be seen that when the wrist is folded upward, it is possible to photograph the back of the hand vein in the wrist wearable device. In order to image the backward vein of the back of the hand, it is intuitive that the position of the camera and the infrared light should be considered in advance, and some adjustments are necessary for precise positioning.

In more detail, a wrist wearable device first folds the wrist up to allow the image of the vein of the hand to be taken (folding up with a fist in order to obtain a clear vein of the vein). After the folding, the position of the wearable wearable device is adjusted by the other hand not wearing the wearable wearable device, so that a sharp image of the vein is taken. At this time, a display such as an LCD may be additionally configured so that the user can check and adjust the taken image of the vein of the hand for precise positioning, which will be described in detail later. Once the correct position has been selected, a vein-based image of the vein can be captured.

Next, a configuration of a camera for photographing a back vein image in the above-described wrist wearable device will be described.

FIG. 3 illustrates an example of a camera (module) and illumination in a wrist wearable device capable of vein recognition according to an embodiment of the present invention.

As shown in Fig. 3, in order to photograph a vein image of a folded hand in the direction of the wearable wearable device, a lens configured to photograph the entire back of the hand with the angle of view bent in the direction of the wearable wearable device, An image sensor for detecting a vein image of the back of the hand, and a memory for storing the taken back vein image should be basically provided.

The lens according to the present invention is designed so that the angle of view of the lens is sufficiently projected in the direction of the wrist type wearable device so that the back of the hand can be grasped sufficiently. The image sensor mainly uses a CMOS image sensor rather than a CCD.

Since the prior art related to the lens, image sensor and memory used for vein recognition is a well known technique, a detailed description is omitted and any lens, image sensor or memory can be used as long as the object and purpose of the present invention are satisfied .

In addition, infrared light, especially near-infrared LED, is used as an illumination, and an infrared band pass filter (IR band pass filter) which selectively passes infrared rays is added. At this time, the near-infrared LEDs use one or more LEDs so that the brightness of the hand to be photographed can be uniformly displayed.

Next, the display in the above-described wrist wearable device will be described in detail.

In order to allow the user to view the image of the vein of the hand when the camera is being photographed and to move the hand or wrist wearable device to a position where the user can quickly obtain a good image of the vein of the hand, And the like can be additionally installed. At this time, a virtual guide line or the like is formed on the display, and the fist is severely rotated to prevent the image of the vein in the back of the hand from being distorted or too small to be blurred.

In the present invention, it is installed at the upper part of the case of the wrist wearable device like a clock, so that it can be installed sufficiently in terms of cost or space, which is due to the physical size.

Next, a camera and a display position and a construction method for photographing a folded back vein image in the direction of the wrist wearable device described above will be described in detail.

As described above, in order to photograph a vein image of a hand-folded hand in the direction of the wearable wearable device, the position and configuration method of the camera and the display are different from those of the conventional method.

(A1) Taking a manual vein image directly with a camera

FIG. 4 illustrates a position and a configuration of a camera and a display for directly photographing a back vein image in a wrist wearable device capable of recognizing a vein according to an embodiment of the present invention.

4, a lens configured to photograph the entire back of the hand when the angle of view is folded in the direction of the wrist wearable device, an image sensor installed at the rear end of the lens for detecting the back vein image input through the lens, A module made of an infrared band pass filter (IR band pass filter) for passing an infrared ray to obtain a vivid palm vein image, and a module composed of a near-infrared LED are placed obliquely on one side of the wrist type wearable device Directly take a vein image of the back of the hand. In this case, the oblique angle refers to the inclination considering the range of the angle at which the lens can have a view angle at which the whole of the back of the user's hand, which has been confirmed through repeated experiments, can be obtained.

(A2) Taking a reflected back vein image with a camera

FIG. 5 illustrates a position and a configuration of a camera and a display for photographing a reflected back vein image by a camera in a wrist wearable device capable of recognizing a vein according to an embodiment of the present invention.

A lens configured to photograph the entire back of the hand when the angle of view is folded in the direction of the wrist wearable device, an image sensor provided at the rear end of the lens for detecting the back vein image input through the lens, A module made up of an infrared band pass filter (IR band pass filter) that passes infrared light to obtain a clear hand vein image and a module composed of a near infrared LED and an IR cut off filter or an IR cut off prism ) Is placed on the front side of the camera to photograph the reflected back vein image.

In this case, the IR cutoff filter or the IR cutoff prism adjusts the reflection angle so that the image of the back vein is divided into an IR cutoff filter or an IR cutoff prism. So that the camera can be brought into the camera. In this case, the reflection angle refers to the inclination considering the range of the angle that allows the lens to have a view angle that allows the whole of the back of the hand, which has been confirmed through repeated experiments.

This method enables the camera module to be operated at any position as compared with the case of directly photographing the vein image of the hand with the camera, thereby overcoming the difficulty of the design in the space limitation of the wrist wearable device.

A description will now be made of a means (hereinafter referred to as a "wearing position detecting unit") for preventing the change of the image of the hand-held vein by recognizing that the wearing position of the wearable wearable device is changed.

Unlike conventional vein recognition devices, wrist wearable devices often determine the position to be worn by a person's habit (right-handed or left-handed). In addition, it is very likely to use both hands alternately instead of dividing the positions to be worn, and there is also a high possibility of wearing them without discriminating between the upper and lower parts.

Therefore, both the positions of the camera and the display and the method of configuring the display are adapted to the hands of the specific direction. When the wrist wearable device is worn on the other hand (for example, a wearable wrist- (Upper and lower) in the same hand, it is highly possible that the image of the vein of the hand is not taken or the image is taken upside down (upside down).

Therefore, in order to be able to capture the vein image of the back of the hand, in order to be able to capture the vein image of the back of the hand, the position of the wearable position detecting unit is changed to the left and right (right and left) 180 degrees is changed so that an error occurs in the vein recognition process. It is possible to prevent the error by manually changing the user or using a sensor that detects the change of the left and right (right and left) and up and down (up and down).

(B1) Means that the user recognizes himself as a marker and changes it manually

First, at least one of colors, characters, symbols, and markers, which is an indicator that can identify left and right (right and left) and up and down (up and down), is selectively displayed on the outer side of the wearable wearable device, The user can change the position of the wearable wearable device by directly informing the user that the up and down (up and down) of the wearable device has been changed, or the user can mount a simple key or an application program in the memory, Change the right hand for the left hand).

(B2) means of using a sensor that detects the change of the left and right (right, left) and up and down (up and down)

A gyro sensor, and a pressure sensor are installed on the inside or outside of the wearable wearable device, and when a change occurs in the left and right (right and left) and up and down (up and down) The wearable device is configured to inform the user through the speaker that the positions of the left and right (right and left) and the up and down (up and down) positions have been changed before the image of the back vein image is captured by the wearable device, The user is informed by the user of the configuration, and the means for changing the direction of the user's forehead or rotating the captured image of the hand-held vein is rotated and rotated 180 degrees.

In addition, the camera is installed on both sides of the wrist-wearable wearable device, and a camera for photographing as the left and right (right and left) and up and down (up and down) positions are changed is also driven so as to acquire a normal directional vein image .

For example, if only a background image (usually black) is taken from a vein image of a hand held by one of the two cameras, the other camera is turned on to photograph the vein of the hand.

In addition, a user can confirm through a display and have a means for directly selecting a camera, so that the user can distinguish the camera in advance.

The gravity sensor is configured to generate a signal by sensing a direction of movement of gravity. The sensor generates a signal when an upward and downward change occurs. The gyro sensor is a sensor capable of detecting a tilt, And to generate a signal by sensing a tilt change. In addition, the pressure sensor is provided with a small-sized pressure sensor capable of detecting a minute pressure on the lower or upper part of a rectangular parallelepiped or cylinder shape, and when a ball or a bearing having a predetermined weight is positioned on the upper part of the pressure sensor, Can be configured to operate.

The following is a description of a means (hereinafter referred to as a "quality measuring unit") for selecting a vein-in-the-vein image (hereinafter, referred to as a "vein-like image of the back of the hand") in a vein image of the back of a hand taken from a wearable- I will look at it.

6 is an illustration for explaining a configuration of a quality measuring unit of a wearable wearable device capable of recognizing a vein according to an embodiment of the present invention.

As shown in FIG. 6, the quality measuring unit includes means for measuring a gray scale difference occurring in the black color of the vein part and the white color seen in the normal skin, which occurs in the vein of the hand vein taken from the camera (hereinafter, (Hereinafter, referred to as an 'interest area setting unit') for designating one or more lines within the ROI as a ROI (Region of Interest) (Hereinafter, referred to as a 'gray value calculation unit') and a gray value difference (hereinafter referred to as a gray value calculation unit) by calculating the gray scale difference as a difference between values of a histogram (a histogram value of a gray scale, (Hereinafter, referred to as " vein image pickup image acquisition unit ") for selecting a vein image having the greatest value as a vein image.

The following is a detailed example of the process of acquiring a vein-like image of the back of the hand from the quality measurement unit from the image of the back of the hand vein.

First, the gray scale measuring unit 601 measures the gray scale difference occurring between the black color of the vein part and the white color seen from the normal skin, which is generated in the vein of the hand vein taken from the camera, And converted into a gray value by the calculation unit 603.

Actually, due to various reasons such as computation time and efficient use of hardware resources, a specific region is set as an ROI without obtaining a gray value in all regions of the hand vein vein image, so that only a portion corresponding to the region of interest (ROI) Measure the difference in value.

At this time, the ROI setting unit 602 may arbitrarily select the region of interest, or may select an area of the outline of the actual fist that is caused by the difference of the gray values of the skin of the fist and the dark background region as the ROI.

It is also possible to calculate the difference in gray value of the area corresponding to the line by drawing one or more lines of interest within the area of interest.

FIG. 7 is a diagram illustrating an example of a characteristic of a vein image of the hand, which appears according to the perspective of the distance from the camera to the back of the hand of the wearable wearable device capable of recognizing veins according to an embodiment of the present invention.

FIG. 7 is a view showing an image of each of the hand vein veins at a position where the distance from the camera to the back of the hand-held wearable device is L1, L2 and L3 (L1> L2> L3) And the gray value of the white color seen from the normal skin is measured and shown in the graph.

As shown in Fig. 7, the gray value reaches only 30 in L1, but the gray value reaches 60 in L2 and the gray value reaches 80 in L3.

FIG. 8 is a diagram illustrating an example of a characteristic of a right-hand vein image according to an exemplary embodiment of the present invention, illustrating a change in a gray value difference between a region of interest (ROI) and a linear region according to a sharpness of an image.

As shown in FIG. 8, the gray values of the ROI of the left hand side in which the sharpness of the taken back vein image is relatively low are distributed from 0 to 80 (left graph). However, the sharpness of the taken back vein image is relatively And the gray value of the ROI on the higher right side is distributed from 0 to 100 (right graph).

Also, the gray value in a region corresponding to an arbitrary straight line is distributed to a value exceeding 90 (left graph), but in the right graph, there is a corresponding value up to 120.

When the gray value exceeds the reference value set in the memory, the vein image of the edible back image acquisition unit 604 draws one or more lines, and the vein image in which the difference value of the gray value obtained from the line is the maximum Select by hand image. At this time, the set reference value is a specific threshold obtained through repeated experiment.

For example, when the difference value of the gray value of the ROI exceeds the set reference value (for example, 80), one or more straight lines are additionally drawn and the difference value of the gray value of the portion corresponding to the straight line region You can choose this maximal inferior vein image as a veinous edible back image.

Next, a means for performing vein recognition (hereinafter, referred to as a vein recognition unit) will be described by comparing an image of an edible back image stored in a memory and stored in a memory with a captured image of a hand vein.

Conventionally, a conventional technique for recognizing veins maximizes the brightness contrast of blood vessels, extracts vein distribution information after extracting the vein, and stores it in a database. Specifically, the following process is performed.

First, the region of interest (ROI) is extracted from the vein image, and then the vein image of the extracted region of interest is preprocessed or the feature is extracted through an algorithm (binarization, thinning, Etc.), and stores the data in a database for comparison. As described above, since the conventional technique for vein recognition is a known technique, a detailed description will be omitted.

Therefore, in the present invention, after the vein image of the back of the hand is taken, the vein image is selected from the vein image of the hand, and then the vein is recognized using the selected vein image. Any vein recognition technology can be used as long as it is available.

Hereinafter, a means for detecting wearing of the wearable wearable device (hereinafter referred to as a wearable wearable part) will be described.

The wearable wearable device has a characteristic that the wearer does not take off easily when wearing the wearable device unlike other devices. Therefore, unlike other security devices, once authentication is performed for the first time, there is an advantage that it can be used safely without additional authentication unless the wrist wearable device is removed.

A spring, a hinge, a magnetic sensor, a capacitive touch sensor, a temperature sensor, and the like are provided on one side (inner side or outer side) of the band of the wrist type wearable device capable of recognizing the vein, A proximity sensor and a connection line for detecting the cut-off of the band are installed at the same time to detect wearing of the wearable wearable device, and a sensor for detecting wearing is attached to the case of the wearable wearable device or attached to the band .

FIG. 9 is an illustration of a magnet sensor and an electrostatic sensor for detecting wear of a wrist wearable wearable device capable of recognizing a vein according to an embodiment of the present invention.

9, when the wearable wearable device is worn by a user, a signal is generated (ON) while being coupled with the magnet sensor 901 and the magnet 902 (as the distance between them is shortened) On the other hand, if you take off (the distance between each other), the signal disappears (OFF). In addition, when the static electricity sensor 905 is coupled with the sensing electrode 906, a static electricity is generated and a signal is generated. When the static electricity sensor is removed, the static electricity disappears and the signal disappears.

10 is an illustration of a temperature sensor and a proximity sensor for detecting wear of a wrist wearable wearable device capable of recognizing a vein according to an embodiment of the present invention.

10, when the wrist wearable device is worn by a user, the temperature sensor 100 detects the temperature of the band when the temperature of the band is higher than the preset reference value, On the other hand, when the band is off, the signal disappears as the temperature of the band falls below the preset reference value. In addition, the proximity sensor detects the proximity sensor 1004 to generate a signal when the wearable wearable device is worn by the wearer, and when the wearable wearable device is removed, the signal disappears (OFF).

At this time, if the connection line of each sensor is constituted in one band and connected to the sensor, it is possible to detect the other worn band without cutting or wearing the other band. Therefore, Even if the band is not cut or worn, it should be constructed so that it can be accurately grasped whether it is worn or not.

The present invention relates to a camera for photographing a back vein image by folding a back of a hand on the basis of a wrist on a side of a case for housing an electronic component and a band surrounding the wrist, And a vein recognition unit for performing vein recognition by comparing the vein image of the vein and the vein image of the back of the hand, which is stored in the memory, with infrared light for capturing a vein image clearly, and a vein recognition unit The device can be used to perform personal security authentication without complexity such as fingerprint or iris recognition, which is highly likely to be used industrially.
