Description

An inscription image acquisition device having a guide around the input window to prevent the inscription from slipping {Nose pattern image generating apparatus having guide member around a nose attachment window so that the nose does not slip on}

The present invention relates to an inscription image acquisition device used for animal inscription authentication and having a guide around an input window so that the inscription does not slip.

Animal authentication is also a process of confirming that they are the same entity as human authentication. For example, it is used when checking lost companion dogs or when it is necessary to check whether it is the same cow whose management number has not changed during the breeding and distribution process, such as a cow raised in a livestock farm.

As a conventionally widely used method for animal authentication, there is a method of attaching a Radio Frequency Identification (RFID) tag to the ear of an animal (eg, cow) or implanting a microchip into the body. However, RFID tags or microchips have the disadvantage of being easily replaceable, and microchips in particular can cause side effects and pain to animals.

Like human fingerprints, inscriptions are a method for recognizing the unique characteristics of individual animals. This is because the inscription, which is the shape of an animal's nose, has individual uniqueness, just like a human fingerprint. Inscription authentication is similar to fingerprint recognition in that it acquires an image of an inscription, registers its features in the shape of the wrinkles, etc., and then authenticates it.

Conventionally, a method of acquiring an inscription image for inscription authentication was a method of directly photographing an inscription using a camera (refer to Korean Patent Publication No. 10-2019-0066323). However, since the method of simply photographing an inscription with a camera is greatly affected by the surrounding lighting conditions as well as direct sunlight, it is not easy to obtain an inscription image with a resolution sufficient to recognize the wrinkle shape of the inscription.

Meanwhile, Korean Patent Registration No. 1706345 suggested an optical inscription authentication device using a prism. This method applies the optical fingerprint acquisition method used for fingerprint recognition as it is. Inscription patterns can also be divided into ridges and valleys like fingerprints. Optical inscription image acquisition uses the fact that different optical processes are performed on the ridges and valleys of the light illuminating the inscription.

The patent suggests the extent to which a prism is used. However, it is not easy to obtain an inscription image capable of recognizing wrinkles, etc., even by the optical inscription image acquisition method proposed by the patent. This is because the animal's nose is humid, so water or oil fills the inscription's troughs, and optical processing similar to ridges occurs in the inscription's troughs, making the ridges and valleys indistinguishable, resulting in a black or entirely bright image.

On the other hand, in optical print authentication using a prism, the animal's nose must come into direct contact with the prism. Due to limitations in communication with animals, it is not easy to bring the animal's nose into contact with the prism. Indeed, because the nose of a healthy animal is rather moist, it easily slides off the face of the prism while in contact with it. If the inscription image acquisition fails several times in this way, things that reject the inscription contact may occur depending on the animal.

Figure 2 is a view optically explaining the operation of the inscription sensor unit according to an embodiment of the present invention, and
Figure 3 is a view from xx by cutting a part of the acquisition device of Figure 1 in a state in contact with the inscription.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 and 2, the inscription image acquisition device 100 of the present invention includes an optical inscription sensor unit 110 provided with an inscription contact surface 101a to which an inscription contacts to generate an inscription image, and an inscription contact surface 101a It includes a case 130 for accommodating the inscription sensor unit 110 therein in a state exposed to one side, and a guide member 150 provided at the edge of the inscription contact surface 101a.

The inscription sensor unit 110 is provided with an optical refractor 201 to optically generate an image of an animal's nose AN, that is, an inscription in contact with the inscription contact surface 101a, which is one surface of the optical refractor 201. As, any conventionally known optical inscription sensor unit 110 is possible. For example, the inscription sensor unit of the applicant's Republic of Korea Patent Registration No. 10-2233244 (Title of Invention: Optical Inscription Image Acquisition Device and Inscription Registration Method) can be used as the inscription sensor unit 110. One side of the optical refractor 201 becomes the inscription contact surface 101a exposed to the outside of the case 130 .

The inscription sensor unit 110 illustratively shown in FIG. 2 includes an optical refractor 201 in direct contact with the inscription, an internal light source 203 for emitting light for obtaining an inscription image with the optical refractor 201, and a light It includes a lens 205 that forms an inscription image emitted from the refractor 201 on an image sensor 207 and an image sensor 207 that finally creates a digital inscription image. The case 130 accommodates the inscription sensor unit 110 so that the inscription contact surface 101a of the optical refractor 201 is exposed to the outside.

The inscription, that is, the animal's nose (AN) is in contact with the inscription contact surface (101a). The area of the inscription contact surface 101a is good enough to contact the nose AN of the animal as a whole so that the inscription image becomes an image of the entire inscription, and therefore the area of the inscription contact surface 101a or the optical refractor 201 The size of may vary depending on the type of target animal. Even in the case of a dog, since the size of the nose is different according to a small dog, a medium dog, or a large dog, it is good to implement a different size of the inscription contact surface 101a according to the type of target dog even when acquiring an inscription image of a dog.

In a state in which the animal's nose AN is in contact with the epileptic contact surface 101a, the internal light source 203 of the epilepsy sensor unit 110 directs the light for image acquisition toward the epitaph contact surface 101a of the optical refractor 201. illuminates The light irradiated by the optical refractor 201 is converted into an inscription image by the inscription in contact with the inscription contact surface 101a, and then is incident on the lens 205. In the scattering type inscription sensor unit 110 as shown in FIG. 2, the light emitted from the internal light source 203 is incident on the inscription contact surface 101a at a right angle or at an angle smaller than the critical angle for total reflection, and the inscription ridge AN2 is As another optical process occurs at the contact part between the contact part and the valley AN3, it is changed into an inscription image. The inscription image is formed on the image sensor 207 by the lens 205. The image sensor 207 acquires an inscription image of an inscription contacting the inscription contact surface 101a by converting and outputting an inscription image into a digital inscription image.

On the outer surface of the case 130, guide members 150 are provided on the upper edge and both side edges except for the lower edge area surrounding the inscription contact surface 101a. 1 and 3, the guide member 150 is formed higher than the contact surface 101a, so that the nose AN of the animal in contact with the contact surface 101a slides upward or to the sides to the contact surface 101a. ) do not deviate. In addition, the inscription image must capture at least the space between the nostrils and the nostrils in the shape of the animal's nose AN, and the upper part of the nose AN must not deviate from the nose contact surface 101a. The guide member 150 guides the animal's nose AN to be accurately placed on the nose contact surface 101a without leaving the contact surface 101a.

The guide member 150 may be disposed on all or part of the upper edge of the inscription contact surface 101a, and may additionally be provided on all or part of both side edges of the inscription contact surface 101a. For example, FIGS. 1 and 3 show an example in which the guide member 150 having a mound-like middle is disposed along the upper portion of the entire upper side edge and both side edges of the inscription contact surface 101a. In addition, the guide member 150 is formed as an inclined surface 151 toward the nose contact surface 101a, so that when the animal's nose AN contacts the nose contact surface 101a, the animal's nose AN moves to the nose contact surface 101a. It is good to be guided by

A guide member is not disposed on the edge of the lower side of the inscription contact surface (101a). In other words, of the outer surface of the case 130, the lower part of the inscription contact surface 101a should be implemented at the same height as the inscription contact surface 101a or a little lower than the inscription contact surface 101a. As shown in Figure 3, it is better not to arrange a guide member even in the lower part of both side edges of the inscription contact surface (101a). That is, of the outer surface of the case 130, the lower part of both sides of the inscription contact surface 101a is preferably implemented at the same height as the inscription contact surface 101a or a little lower than the inscription contact surface 101a. As shown in FIGS. 1 and 3, the lower part of the lower part and both sides of the nasal contact surface 101a may be implemented a little higher than the nasal contact surface 101a, but the height of this structure is the same as the guide member 150, the animal's nose (AN) It must not be at a height that prevents slipping or obstructs the way.

When the nose AN contacts the nose contact surface 101a, as shown in FIG. 3, the upper part of the nose AN is guided by the guide member 150 and tries to make contact in such a way that it is located near the upper side of the nose contact surface 101a. However, the guide member disposed at the lower edge of the lower side and / or the lower side of the nose contact surface 101a may press the nose of the animal when the nose of the animal contacts the contact surface 101a, or the nose of the animal. It can be pushed away from the contact surface (101a), which hinders the acquisition of the inscription image. For the same reason, it is better not to place a guide member on the lower part of both side edges of the inscription contact surface (101a).

It is preferable that the guide member 150 is made of an elastic material so that the animal does not press the nose and cause pain. As a material for the guide member 150, elastic silicone or the like may be used. The shape of the guide member 150 can be designed in various ways. Since the characteristic guide member 150 of the present invention is to prevent the nose AM from slipping and leaving the nasal contact surface 101a, several pillars or semicircular elastic members may be arranged at regular intervals. .

Although the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, and is common in the art to which the present invention belongs without departing from the gist of the present invention claimed in the claims. Of course, various modifications are possible by those with knowledge of, and these modifications should not be individually understood from the technical idea or perspective of the present invention.
