Description

Contact-type nose reader for pets

The present invention relates to a contact-type inscription reader for companion animals, and more particularly, to a contact-type inscription reader for companion animals that can obtain an accurate inscription image regardless of the state of the companion animal during authentication of the companion animal inscription (nose fingerprint). it's about

In recent years, since the demand for companion animals is increasing explosively, animal certification to certify one's own companion animal is being made.

This authentication serves as a resident registration number of a normal person by making it easy to confirm that it is one's companion animal among several companion animals when the companion animal is lost.

The earliest authentication means was to hang an identification tag in the form of a necklace, and it was most easily applied, and an identification code marked with numbers or letters was recorded on the identification tag.

Another method is to use an RFID (Radio Frequency Identification) tag, for example, a method of attaching an RFID tag to a cow's ear, or a method of inserting a microchip into the skin of a companion animal and recording genetic information How to do it is applied.

However, the RFID tag exposed to the outside cannot be checked even if it is replaced, and the microchip inserted into the skin causes side effects and pain to the animal, but can be easily removed. In addition, the method of registering genetic information does not have the possibility of modification, but has a disadvantage in that it cannot be immediately confirmed.

Accordingly, recently, a method for authenticating an inscription using the ridge shape of a companion animal's nose has been proposed. In other words, this is because the ridge formed on the nose of an animal is unique like a human fingerprint.

Such inscription authentication is a method of acquiring the image of the inscription through an inscription reader, registering the shape features of the ridges, and then authenticating. Reader is applied.

The inscription reader attaches the exposed prism 10 to the nose 20 of the animal made of various patterns of ridges and valleys as shown in FIG. By transmitting the image to the storage device and storing the image together with the personal information in the storage device, the inscription image is acquired in the same way during authentication later.

However, the contact-type non-text reader also has a problem in that an error in which the acquired image is inconsistent with the registered image frequently occurs.

This is usually composed of the ridges 21 of various shapes by the ridges (A) of the dog's nose (20), which is a deep bone (谷), in particular, as shown in FIG. Since flat gongs, which are shallow valleys (indicated by the yellow line), are formed in the base 21 region, when shooting is performed with the prism 10 in contact with the nose 20, the flat valley ( This is because, as B) is sealed, the air remaining inside the flat valley acts as a medium and reflects light, thereby bending the flat valley of the ridge as a white blank as shown in FIG. 2(B).

In addition, the above inscription distortion may vary depending on the dog's condition, especially if there is a lot of moisture in the dog's nose, because the moisture remains in the flat valley and reflects the light.

Domestic Patent Publication No. 10-2021-0013901

The present invention has been devised to solve the above problems and technical biases, and the environment of the nose is different depending on whether there is a flat curve in the ridge forming the inscription of the companion animal or the condition of the condition of the companion animal. The purpose of this is to provide a contact-type inscription reader for companion animals that can always obtain accurate inscription images, even though it is not.

In this case, the inscription photographing unit may include: a prism having a contact surface on one side of which is in contact with the inscription, and an emitting surface having a predetermined angle for refracting the provided light; an inscription pressing pad made of a transparent elastic material that is disposed on the contact surface of the prism to transmit light and elastically deforms and closely adheres to the inscription of the companion animal when it is in close contact with the inscription of the companion animal; and a pad detachment hole for detachably inserting the inscription pressure pad into the contact surface of the prism.

In addition, the pad detachable hole, an insertion groove is formed on one side of the circumference, the body is formed with an opening in the front; a pad insertion end formed on the rear surface of the opening of the body and inserted such that the inscription pressure pad is exposed through the opening; and a tapered surface extending obliquely backward from the pad insertion end, to which one end of the exit surface of the prism is inserted and coupled.

And, an air flow path for forming an air layer by spraying air to the surface of the contact surface so as to slip with the contact surface of the prism when the inscription pressure pad having elasticity is inserted into the pad removal hole is formed inside the pad detachment hole it is preferable

In addition, the inscription pressure pad is formed along the circumferential direction on one surface of the inscription pressure pad and communicates with the air flow path, and the inscription pressure pad inserted into the pad detachment hole through the suction of the air flow path is in close contact with the contact surface of the prism in a vacuum. It is preferable that an air adsorption path is further formed.

On the other hand, when the inscription pressure pad is in close contact with the inscription, it is preferable to fill in the flat valleys formed on the ridges of the companion animal's nose and to be in close contact.

In this case, the thickness of the inscription pressure pad is preferably in the range of 1mm to 0.7mm.

In addition, the inscription pressure pad is preferably made of silicone or urethane.

Finally, it is preferable that an image display unit for displaying an image obtained through the camera unit and the inscription photographing unit is further provided on one side of the main body.

According to the contact-type inscription reader for companion animals of the present invention having the above configuration, when photographing the contact-type inscription of a companion animal, the flat-gok formed in various ways on the ridge of the inscription is filled by the inscription pressure pad, It has an excellent effect of fundamentally blocking the distortion of the image for authentication because it is possible to obtain an accurate image of the inscription at all times regardless of the shape of the animal or the condition of the companion animal.

In addition, since the inscription pressure pad is perfectly in close contact with the prism surface by vacuum by air, there is an effect of blocking the refracting of the irradiated light during photographing.

In addition, since the inscription pressure pad is detached through air injection and suction, the structural effect of easy maintenance and replacement is also excellent.

As shown in FIGS. 3 to 10 , the contact-type door reader 500 for companion animals of the present invention includes a body 100 having a handle 110 ; a camera unit 200 provided in the main body 100 and configured to photograph the face or nose shape of the companion animal; The inscription photographing unit 300 provided in the main body 100 to close the nose of the companion animal in a pressurized state, and to photograph the inscription image while filling the flat valleys (B) formed in the protuberance 21 of the nose. ); And the control unit 400 that extracts the image data obtained through the camera unit 200 and the inscription photographing unit 300, sends it to the management server for registration, and compares and authenticates the previously registered image data with the acquired image data. includes ;

Prior to the description, the biggest feature of the contact-type inscription reader 500 for companion animals of the present invention is that the inscription pressure pad 320 is applied to the inscription pressure pad 320 when photographing the inscription for authentication of the companion animal to form a flat ridge formed on the protuberance 21 of the nose ( B) (平谷) is to be filled in to block the distortion of the authentication image.

There are various types of companion animals, such as dogs and cats, but will be described as 'company dogs' below.

The inscription reader 500 of the present invention is in contact with the nose with a predetermined pressure in order to obtain an image of the inscription of the dog's nose.

The inscription reader 500 of the present invention can accurately acquire the inscription image of the dog as shown in FIG. 4 . That is, as shown in Fig. 2(a), the shape of the flat valley (B) (平谷) made of the shallow valley formed in the ridge 21 of the inscription is not expressed on the acquired image.

The main body 100 maintains the shape of each type as a whole so that the camera unit 200, the inscription photographing unit 300, the control unit 400, the image display unit 113, etc. to be described later can be installed as shown in FIG. There is, on the lower side of the main body 100, a handle 110 that a user can hold by hand for taking an inscription is provided, and an operation button 111 for executing the described configuration is provided on the handle 110. have.

The operation button 111 starts the operation of the camera unit 200 or the inscription photographing unit 300 to be described later, and may be implemented through various operating means such as a button method or a trigger method.

Here, the shape of the main body 100 may have various designs according to the arrangement of each installed structure.

The camera unit 200 is disposed in the downward direction on the left side of the main body 100 in the drawing, and takes the overall shape of the dog or the shape of the face and the shape of the nose.

The camera unit 200 has a conventional structure, and is preferably installed to be exposed from the main body 100 as the photographing is to be made toward the dog, and transmits the photographed image of the dog to the control unit 400 to be described later.

That is, taking an image of a dog through a camera is to register the authentication information of the target dog, and depending on the authentication method, the dog's face or the dog's nose (inscription) is the target.

The inscription photographing unit 300 is arranged to protrude upwardly on the left side of the main body 100 in the drawing as shown in FIG. 3, and is in close contact with the nose while the dog's nose is pressed with a predetermined pressure, so that the protrusion 21 of the nose The inscription image of the dog is taken while allowing the space of the flat valley (B) (平谷) formed in the to be filled by the inscription pressure pad 320 to be described later.

That is, the inscription photographing unit 300 is brought into close contact with the nose portion corresponding to the position of the previously registered inscription image to take a photograph while applying a predetermined pressure.

At this time, the applied pressure is sufficient as long as the surface of the inscription pressure pad 320 having elasticity is filled while being pushed into the space of the raised portion 21 flat valley (B) (see FIG. 10 ).

And, since the inscription photographing unit 300 must be photographed in close contact with the dog's nose, it is preferable to be installed to be exposed from the main body 100, and the photographed inscription image of the dog dog is sent to the control unit 400 to be described later. is sent

The inscription photographing unit 300 as described above includes a prism 310, an inscription pressure pad 320, and a pad detachment hole 360 as shown in FIGS. 5 to 10 .

The prism 310 has a contact surface 311 flatly formed with a predetermined area so that the left side in the drawing can contact the dog's inscription as shown in FIG. 6 , and the other side of the contact surface 311 is a rear light source (not shown) ) is formed with an exit surface 312 having a predetermined angle for refracting the light irradiated from it, and the exit surface 312 is accommodated inside the body 100 .

Although not shown on one side of the prism 310 and the exit surface 312 inside the body 100, a lens and an image sensor for imaging the inscription image emitted to the exit surface 312 are disposed, and the inscription through the image sensor By converting the image into a digital inscription image and outputting it, the image of the inscription in contact with the contact surface 311 of the prism 310 is created.

Since the method of creating an image through the prism 310 is a general matter, a detailed description thereof will be omitted.

The inscription pressure pad 320 maintains an area corresponding to the contact surface 311 of the prism 310 as shown in FIGS. 5, 6 and 8, is disposed in close contact with the contact surface 311, and is irradiated from the light source It is formed of a transparent material with excellent transmittance so that it can be transmitted.

In addition, the inscription pressure pad 320 has a flat surface on the front and back, and is physically elastic to fill the flat curve (B) (平谷) of the ridge 21 when it is in close contact with the dog's inscription, that is, the nose with a constant pressure. It is formed of a flexible elastic material so that it can be closely attached to the nose while being deformed.

That is, the inscription pressure pad 320 is made of a transparent elastic material and is disposed on the contact surface 311, which is the outside of the prism 310, to press the prism 310 to the inscription by a predetermined pressure to take the inscription. When, in the process of being pressed, the space of the flat valleys (B) formed on the ridge 21 of the dog's nose is filled in as shown in FIG. 10 and is in close contact.

In this way, since the flat valley B is closed as in the prior art, the problem of bending the shape of the ridge 21 by reflecting light from the air remaining in the flat valley B is solved, so that an accurate inscription image can be obtained ( see Fig. 4).

On the other hand, it is preferable to maintain the thickness of the inscription pressure pad 320 in the range of 1 mm to 0.7 mm. This is because when the thickness of the inscription pressure pad 320 is 1 mm or more, the refraction of transmitted light occurs severely when elastic deformation is made. The distortion of the image occurs, and, conversely, if it is 0.7 mm or less, the thickness of the inscription pressure pad 320 is thin, so the elastic deformation due to pressure is small, so that the problem that the filling of the flat curve (B) is not performed properly occurs.

In addition, the inscription pressure pad 320 may be made of a silicone or urethane material, and the type of material is not limited as long as it can transmit light and have elasticity.

In addition, an air adsorption path 321 is formed on the rear surface of the inscription pressure pad 320 , and the air adsorption path 321 will be described later.

The pad detachment port 360 allows the inscription pressure pad 320 to be detachably inserted from the contact surface 311 of the prism 310, and is shown in a state in which the inscription pressure pad 320 and the prism 310 are provided. 3 is coupled to the body 100 .

The pad detachment hole 360 includes a body 330 , a pad insertion end 340 , and a tapered surface 350 .

In the body 330, an insertion groove 331 is formed in the upper direction in the drawing as shown in FIGS. 5 and 6 in a state of maintaining a predetermined thickness and a rectangular shape as a whole, and a pad insertion end 340 is formed on the front side of the left side in the drawing. ), a rectangular opening 332 is formed so that the inscription pressure pad 320 inserted into the inscription is exposed to the outside so that it can come into contact with the dog's nose during inscription authentication.

That is, the insertion groove 331 and the opening 332 of the body 330 are in communication with each other.

The pad insertion end 340 is formed in a vertical direction to communicate with the insertion groove 331 on the rear surface of the opening 332 in the thickness direction of the body 330, and the inscription pressure pad 320 is inserted through the insertion groove 331. By forming a space so that it can be inserted, the inserted inscription pressure pad 320 can be exposed through the opening 332 .

At this time, of course, the width and area of the pad insertion end 340 is slightly larger than that of the inscription pressure pad 320 .

The tapered surface 350 extends obliquely from the pad insertion end 340 toward the rear at a predetermined angle, and allows one end of the exit surface 312 of the prism 310 to be inserted and coupled as shown in FIG. 8 .

Here, it goes without saying that the angle of inclination of the tapered surface 350 is formed to correspond to the inclination of the exit surface 312 of the prism 310 .

As described above, when the prism 310 is coupled to the tapered surface 350, one surface of the inscription pressure pad 320 inserted into the pad insertion end 340 comes into contact with the contact surface 311 of the prism 310, so they are in close contact with each other. will maintain the status quo.

In addition, the inscription pressure pad 320 is easily inserted even though it is a flexible material having elasticity when inserted into the pad insertion end 340 of the pad detachment port 360, and the contact surface 311 of the prism 310 is vacuumed on the surface. to remain in contact.

To this end, when the inscription pressure pad 320 having a flexible elasticity is inserted into the pad insertion end 340 through the insertion groove 331 in the body 330 of the pad detachment port 360, the prism 310 of the An air flow path 333 for forming an air layer by spraying air onto the surface of the contact surface 311 is formed as shown in FIG. 9 so that the contact surface 311 and the slip are made.

The air flow path 333 maintains a predetermined space so that air supplied from the outside can flow, and is formed along the circumference of the body 330 forming the opening 332 .

Of course, at least one air pipe for supplying or sucking air is connected to the air flow path 333 .

At the same time, one surface (surface in contact with the contact surface of the prism) of the inscription pressure pad 320 having flexible elasticity is formed along the circumferential direction as shown in FIG. 7 and communicates with the air flow path 333 of the body 330, , through suction of the air flow path 333 , the inscription pressure pad 320 inserted into the pad insertion end 340 of the pad detachment port 360 is in close contact with the contact surface 311 of the prism 310 by vacuum. A furnace 321 is formed.

At this time, the air adsorption path 321 is formed as a recessed groove to allow air to flow, and extends from the air adsorption path 321 to a plurality of communication paths ( 322) is formed.

The plurality of communication paths 322 communicate with the air flow path of the body 330 as shown in FIG. 8 at the same time as the inscription pressure pad 320 is inserted into the pad insertion end 340 .

In the air flow path 333 of the pad detachment port 360 and the air adsorption path 321 of the inscription pressure pad 320 as above, the inscription pressure pad 320 is the pad insertion end 340 of the pad detachment port 360. ) when inserted into the air flow path 333 by spraying air to the surface of the contact surface 311 of the prism 310 through the air layer to form an air layer, so that the inscription pressure pad 320 with thin and flexible elasticity is formed by the air layer. To allow the insertion to proceed without contacting the contact surface 311, and in addition, in the state where the insertion of the inscription pressure pad 320 is completed, the air in the air suction path 321 is sucked through the air flow path 333 to suck the air By allowing the suction furnace 321 and the contact surface 311 to contact in a vacuum, a stable contact state between the inscription pressure pad 320 and the contact surface 311 is maintained.

In addition, when the inscription pressure pad 320 is to be withdrawn from the pad removal port 360 for removal and replacement, air is supplied to the air absorption passage 321 to release the vacuum applied to the air absorption passage 321 . At the same time, after separating from the contact surface 311 of the prism 310, the inscription pressure pad 320 can be easily withdrawn.

In the present embodiment, the air adsorption path 321 is illustrated as being formed in a rectangular shape along the circumference of one surface of the inscription pressure pad 320 , but it may be formed in various ways as long as it communicates with the air flow path 333 .

The control unit 400 is installed inside the body 100 in a state of being electrically connected to the camera unit 200 , the inscription photographing unit 300 , the operation button 111 , and the image display unit 113 .

The control unit 400 extracts the image data of the dog's face and nose photographed through the camera unit 200 or the inscription image data photographed through the inscription photographing unit 300 and transmits it to the management server connected by wire or wireless for management The registration is made through the server, and it is authenticated by comparing the pre-registered dog face, nose shape, and inscription image data.

That is, the controller 400 reads whether the registered image matches the image captured for authentication.

Since the above control unit 400 is a technology applied to authentication of a dog, a detailed description thereof will be omitted.

Meanwhile, an image display unit 113 for displaying images acquired through the camera unit 200 and the inscription photographing unit 300 may be further provided on the right inclined surface of the main body 100 in the drawing.

The image display unit 113 is electrically connected to the control unit 400 , and allows the user to take a picture while checking a displayed image, and to check a captured image image.

Hereinafter, a process of acquiring an inscription image using the inscription reader 500 according to the present invention will be described with reference to the accompanying drawings.

First, a dog subject to be authenticated is positioned, and the inscription photographing unit 300 is applied to the dog's nose while holding the handle 110 of the inscription reader 500 and adhered to it by applying a predetermined pressure to the dog's nose.

At this time, the inscription pressure pad 320 is in close contact with the dog's nose, and is elastically deformed as shown in the enlarged view of FIG. 10 by the applied pressure to fill the spaces corresponding to the grooves of the flat valley B.

When the operation button 111 is pressed in the above state, light from the light source is irradiated toward the inscription, and the irradiated light is reflected by the inscription to form an image of the inscription on the exit surface 312 of the prism 310 while forming a lens and an image The inscription image is converted into an inscription image through the sensor and output.

At this time, since the depth of the raised portion 21 flat gong (B) is usually formed within 1 mm, even if the flat gong (B) is not completely filled by the inscription pressing pad 320, the obtained inscription image is reliable. For example, if the depth of the flat valley (B) is 0.7 mm, the depth filled by the inscription pressure pad 320 is 0.5 mm, and even if a gap of 0.2 mm occurs, the air layer remaining in the space of 0.2 mm is almost impossible to photograph. because it doesn't affect it.

Thereafter, the inscription image converted through the image sensor is transmitted to the control unit 400, the control unit 400 reads whether the previously registered inscription image and the inscription image photographed for authentication match, and through the image display unit 113 Indicate whether or not to authenticate.

As described so far, in the contact-type inscription reader for companion animals of the present invention, when the inscription of the contact-type companion animal is photographed, the pyeonggok (平谷) formed in various ways on the ridge of the inscription is filled by the inscription pressure pad. Since accurate images of inscriptions can be acquired at all times regardless of the shape or condition of the companion animal, it has an excellent effect of fundamentally blocking the distortion of the image for authentication.

In addition, since the inscription pressure pad is perfectly in close contact with the prism surface by vacuum by air, there is an effect of blocking the refracting of the irradiated light during photographing.

In addition, since the inscription pressure pad is detached through air injection and suction, the structural effect of easy maintenance and replacement is also excellent.

As mentioned above, although the preferred embodiment and the accompanying drawings have been described for the contact-type non-municipal reader for companion animals of the present invention, this is only intended to help the understanding of the invention and is not intended to limit the technical scope of the present invention.

That is, without departing from the technical gist of the present invention, various modifications and alterations are possible by those skilled in the art to which the present invention pertains. It goes without saying that it is within.
