Biometric technology refers to a technology that identifies or identifies an individual using biometric information. To date, biometrics technology has identified personal identities using fingerprints, faces, irises, or voices.

In the fingerprint recognition technology, the recognition device is small and can be mass-produced inexpensively. It also shows relatively good performance in terms of recognition accuracy and speed. However, fingerprints are exposed outside the body, and are easily stolen and may be deformed by sweat, which may affect recognition performance. There are also hygiene problems. Iris recognition technology is the most reliable biometric technology in that it is unlikely to cause a recognition error and difficult to forge. However, most people are reluctant to shine light directly on their eyes for iris recognition, and the iris recognition device has the disadvantages of being large and expensive. Face or voice recognition technology has the advantage that it is the most natural form of biometric information for identification. However, in terms of accuracy of recognition, it has a disadvantage in that its accuracy is inferior to other technologies.

In order to compensate and overcome the shortcomings of the above-described biometric recognition technologies, a vein recognition technology is currently being developed. Vein recognition technology refers to a technology that identifies an individual using a vein pattern image acquired through infrared rays. Human veins are located under a complex shape under the skin, and according to various studies, the patterns of veins are different for each individual, and it is known that the pattern does not change with age. The vein recognition technology has the following advantages. In other words, since the veins exist inside the body, there is little risk of theft or forgery, and the condition of the skin surface has no effect on recognition. In addition, a non-contact device with high user convenience can be constructed using infrared rays, and the vein pattern can be stably and relatively clearly found, so a camera with a low resolution can be used to obtain a vein image that is small and simple in image processing. That is, the vein recognition technology can provide a balanced performance in terms of security and convenience.

Due to these advantages, the recent vein recognition technology is more difficult to tamper with than fingerprint, iris, face, and voice recognition technology, so it is possible to implement a biometric authentication device with higher safety and miniaturization, so it is expected to be applied to various fields. Is becoming.

On the other hand, the characteristics of these vein patterns are not only seen in humans, but also appear in different unique characteristics in mammalian animals. Therefore, the vein recognition technology can be applied not only to humans but also to animals in the future, and the need for vein recognition devices for animals is also increasing. In particular, pets such as dogs and cats can be managed as separate systems through vein pattern recognition and registration.

The vein recognition technology may be applied to animals as described in the background art, where the animal means a mammalian animal, and hereinafter, the expression animal is simply defined as a mammalian animal. In the animal's ear 10, in particular, the veins appear well on the medial surface 12 rather than the external surface 11 of the ear 10 so as to be externally observable. The outer surface of the ear 10 is generally hairy, so it is not easy to observe a vein. The vein image photographing apparatus 20 of the present invention is for photographing a vein formed in the ear 10 of an animal, and in particular, may be formed to facilitate photographing a vein formed in the inner surface of the ear 10 of the animal. have.

The animal vein image photographing apparatus 20 according to an embodiment of the present invention includes a photographing case 100, an infrared lamp 200, and a camera 300.

The photographing case 100 is formed with an internal space so that the animal's ear 10 can be inserted. For example, it may be formed in the form of a hollow pipe, an insertion opening 101 into which an animal's ear is inserted is formed on one side of the photographing case 100, and an end of the animal's ear 10 penetrates through the other side to be exposed externally. The through opening 102 may be formed so as to be possible. The other side of the photographing case 100 may be formed in a closed form rather than the through opening 102. However, the size of the animal's ear 10 varies depending on the type of animal, and when the other side of the shooting case 100 is formed in a closed shape, it is difficult to insert the ear 10 of various sizes, and the ear 10 If is relatively large, in the process of inserting the ear 10 into the shooting case 100, the end of the ear 10 may be difficult to be pressed or folded by the other end of the shooting case 100, so the shooting case 100 By forming a through opening 102 at the other end of the, it is preferable that the animal's ear 10 penetrates the shooting case 100 and is exposed to the outside.

In addition, the portion where the insertion opening 101 of the imaging case 100 is formed may be formed in a concave curved shape so as to be in close contact with the side of the head 13 where the animal's ear 10 is formed. That is, in general, the head 13 of the animal is formed in a convexly curved shape in an outward direction in a round shape, and thus, the insertion opening 101 of the photographing case 100 is formed in an animal as shown in FIG. 3. By being formed in a concave curved shape corresponding to the shape of the head 13, one end of the photographing case 100 may be in close contact with the head 13 of the animal, whereby the animal's ear 10 is the photographing case It can be completely inserted inside (100).

In particular, through this structure, the animal's ear 10 can always be inserted into the shooting case 100 with a uniform depth, so that the position of the animal's ear 10 for shooting can always be constant.

On the other hand, the photographing case 100 may be formed with a handle portion 110 that the user can hold and operate in the hand, and the handle portion 110 is operated for manipulation such as an infrared lamp 200 and a camera 300 Button 111 may be provided. In addition, the shooting case 100 may be formed of a transparent material to enable the camera 300 to be photographed with respect to the ear 10 inserted therein, and to visually observe the insertion state of the ear 10.

The infrared lamp 200 is mounted on the photographing case 100 and emits infrared light to pass through the animal's ear 10 inserted into the photographing case 100. The camera 300 is mounted on the photographing case 100 and photographs an image of a vein formed in the animal's ear 10 through infrared rays transmitted through the animal's ear 10. An infrared camera is applied to the camera 300.

That is, when infrared rays are projected to the animal's ear 10 by the infrared lamp 200, the vein of the animal's ear 10 absorbs infrared light and the portion other than the vein transmits infrared light. Accordingly, when the animal's ear 10 is photographed through the camera 300, a vein image formed in the animal's ear 10 may be photographed. There are various types of such a vein imaging method, such as contactless contactless, and various vein imaging methods commonly used may be applied.

At this time, the infrared lamp 200 is arranged to irradiate infrared light on the outer surface 11 of the animal's ear 10 while the animal's ear 10 is inserted into the shooting case 100, and the camera 300 ) May be disposed to face the infrared lamp 200 so as to be able to photograph the inner surface 12 of the animal's ear 10 while the animal's ear 10 is inserted into the imaging case 100.

According to this arrangement structure, the camera 300 photographs the inner surface 12 of the ear 10, so that the vein pattern mainly observed on the inner surface 12 of the ear 10 can be more clearly photographed.

In addition, the camera 300 is fixedly mounted to the shooting case 100, as shown in FIGS. 2 and 4, may be arranged to be spaced apart from the shooting case 100 at a predetermined interval. To this end, a separate support frame 120 is coupled to one surface of the shooting case 100, and the camera 300 may be fixedly supported by the support frame 120.

As such, by positioning the camera 300 away from the shooting case 100, the shooting range of the camera 300 is relatively increased, and accordingly, the vein image of the ear 10 inserted inside the shooting case 100 Since it can be taken in a wider range, it is possible to improve the accuracy of the analysis work when analyzing a vein pattern image taken later.

5 is a view schematically showing the operating state of the opening control plate of the ear vein imaging device of an animal according to an embodiment of the present invention.

As described above, since the size of the ear 10 is different depending on the type of the animal, the end of the ear 10 penetrates the shooting case 100 in the process of inserting the ear 10 into the shooting case 100, so that the outside Through the opening 102 is formed on the other side of the shooting case 100 to be exposed.

However, when the size of the animal's ear 10 is different, as shown in FIGS. 5 (a) and 5 (b), the length of the ear 10 as well as the width are formed differently. Thus, when the width of the animal's ear 10 is different, for example, as shown in (b) of FIG. 5, when the size of the animal's ear 10 is small, the ear 10 is photographed case 100 In the process of inserting into the ear 10, the insertion position of the ear 10 cannot be kept constant in the width direction.

As described above, the insertion opening 101 portion of the shooting case 100 is formed concavely and is in close contact with the head 13 portion, whereby the insertion position of the ear 10 (the ear 10 and the shooting case 100 relative to each other) Position) may be kept constant based on the length direction of the ear 10. However, when the width of the ear 10 is smaller than the width of the insertion opening 101 of the shooting case 100, the relative position of the ear 10 and the shooting case 100 based on the width direction of the ear 10 Cannot be kept constant.

If the insertion position of the ear 10 cannot be kept constant, different parts of the ear 10 are photographed every time the vein image is photographed, and thus the object recognition operation using the vein image cannot be stably performed.

In one embodiment of the present invention, regardless of the size of the animal's ear (10), the position of the ear (10) inserted into the shooting case (100) is shown in FIG. As described above, a separate opening adjustment plate 130 may be provided.

The opening adjustment plate 130 is coupled to the insertion opening 101 of the imaging case 100, and may be configured to move in a slide manner to adjust the opening area of the insertion opening 101. If the animal's ear 10 is relatively large according to this structure, as shown in Fig. 5 (a), the opening adjustment plate 130 slides to increase the opening area of the insertion opening 101, and If the ear 10 is relatively small, as shown in Fig. 5 (b), the opening adjustment plate 130 can be slided so that the opening area of the insertion opening 101 decreases, through which the shooting case ( 100) the position of the ear 10 to be inserted can be kept constant based on the width direction.

At this time, when adjusting the slide movement of the opening adjustment plate 130, the end of the opening adjustment plate 130 comes into contact with one side of the ear 10. Since this contact may cause damage to the ear 10, it is prevented. In order to do so, a protective member 131 made of a soft material capable of preventing injury to the ear 10 of the animal may be coupled to the end of the opening adjustment plate 130.

6 is a view schematically showing an operating state of the hair guide means of the vein imaging device of an animal according to an embodiment of the present invention.

As described above, the animal's ear 10 has a lot of hair on the outer surface 11, and there is no hair on the inner surface 12, so it is easy to observe the vein. Therefore, the camera 300 is within the ear 10. It is arranged to photograph the side 12.

However, as shown in Fig. 6 (a), depending on the type of animal, the hair 14 is lush on the outer surface 11 of the ear 10 and its length is long, so that the inner surface 12 of the ear 10 is long. ). In this case, even if the inner surface 12 of the ear 10 is photographed through the camera 300, the inner surface of the ear 10 by the hair 14 extended to the inner surface 12 of the ear 10 The intravenous imaging formed in (12) is not easy, and noise caused by the hair 14 is generated in the captured image, and thus the accuracy of the image deteriorates.

In one embodiment of the present invention, for the animal's ear 10 inserted into the shooting case 100, the hair 14 generated in the animal's ear 10 can be guided to the outer portion of the animal's ear 10. So that the hair guide means 400 is provided.
