Description

Inscription photographing system {Animal nose print photographing apparatus}

The present invention relates to an inscription photographing system, and more particularly, to an inscription photographing system capable of obtaining a clear inscription image.

The method of identifying the individual of an animal has been used for a long time in history, and has been used a lot to prevent theft of very valuable animals such as horses. In recent years, in addition to the purpose of verifying ownership to defend against theft or theft, it is essential in the process of importing and exporting livestock animals, as well as production and management of livestock animals, control of animal disease outbreaks in farms, management of extinct and protected animals, and import and export of various animals. It is also used for quarantine that occurs.

Traditional methods of managing animal entities include ear tearing, which is mainly used for pigs, attaching plastic or barcoded tags to cows or sheep's ears, wrapping chains with numeric tags around the neck in place, and A method of engraving a pattern by cooling a number or letter-shaped metal on the body with liquid nitrogen, dry ice, and alcohol, and painting or tattooing the animal's body were used.

In the second half of the 20th century, a method of comparing the inscriptions of cows or sheep with ink on paper was attempted, but the traditional method had several disadvantages due to the characteristic of using primitive means.

Except for collecting inscriptions or painting, most methods involve damage to certain parts of the animal in the process of work, and may affect the safety of workers and animals due to the pain, seizure and rejection of the animal. , It requires a lot of work time. In addition, it is almost impossible for non-professionals to use it without the help of experts, and there are many problems in terms of animal welfare.

In addition, even when the work is completed, there is a disadvantage in that it is impossible to distinguish the object, which is the original purpose, if the surrounding environment is dark to identify numbers or letters, or if the existing display method is damaged due to actions performed to mark the area of animals. .

In addition, there is a limitation in that it is impossible to distinguish individuals even when letters, numbers, and specific parts displayed in the traditional way are deliberately damaged or forged by humans.

Among the traditional methods, it is known that the method of using the cow's inscription can overcome the disadvantages of the previous methods. From the second half of the 20th century, when it was widely known that cow inscriptions have the uniqueness of each individual like human fingerprints, various attempts have been made using them. This method used the same method as human fingerprints to collect cow inscriptions. The inscription was obtained by wiping the cow's nose to remove foreign substances, applying ink to the area, and making a transcript with paper.

However, depending on the operator's skill level, ink smears or pressure to press the nose was changed, so that not only the transcript image was changed, but even if performed by the same person, there was a problem that a different transcript image was generated each time depending on the direction in which the text was drawn.

In addition, since most animals' noses are wet with water and foreign substances come into contact with their noses, they lick with their tongues, so there is a problem that takes a lot of time because the operation has to be repeated every time a rubbing is performed.

In order to overcome the limitations of these existing traditional methods, many trials and studies are being conducted, and they can be classified into two main directions. The first direction is to study the method of using the electronic identification device, and the second is to study the method of using the biometric information unique to the animal.

The method of using the electronic identification device is to embed a microchip and an antenna in an animal object into a tag, insert it into the skin tissue, or place it on the digestive organ by swallowing it, and scan the information contained in the microchip and identify it through a recognizer. will be.

However, this method also cannot be recognized unless the microchip or antenna is damaged or there is no device capable of scanning, and as with the traditional method, it is not possible to identify individuals if they are deliberately damaged or forged.

In addition, according to some studies, there is a problem that the microchip inserted into the animal object and the material surrounding the antenna are known to cause a phenomenon such as tumor or tissue necrosis in the body of the animal object, and are not 100% safe for animals. For this reason, farmers and people who have companion animals tend not to prefer it because of a strong reluctance.

The method of using the unique biometric information of an animal individual has a high reliability that cannot be compared with the conventional method described above and the use of an electronic identification device. This is because it uses the unique and innate features of an animal individual, and is inherently impossible to forge or alter.

Recently, studies on analysis using iris images, analysis using retina images, DNA analysis, and inscription image pattern analysis are in progress. The reality is that the iris image, retinal image, and DNA analysis have not yet reached a sufficient level in terms of technical and cost to be applicable in the field.
