Description

Facial image acquisition device of livestock

Technical Field

The utility model relates to a livestock breeding intelligence technical field specifically indicates a facial image acquisition device of livestock.

Background

Animal food safety is a problem of wide concern of people, the life and health of people are affected, and various links from 'farms' to 'consumers' are worried about the animal food safety. The first place is that the basic information, feed information, veterinary drug information, inspection and quarantine information and transferring information of the enterprises of the farm are closely related to the safety of animal food. The management methods for raising animals in a farm can be roughly classified into the following categories: physiological characteristics (iris, vein, face), physical technology (RFID), biological technology (DNA).

RFID identification: the method is the most common technology for identifying the live pigs at present, and is realized by mounting ear tags on the ears of the live pigs and reading ear tag information through an RFID antenna of equipment to identify individual live pigs.

Iris recognition: in physiological research, the iris grammatical detail features are randomly determined, can be quickly formed and stably convenient for individual identification, and are mainly applied to scenes such as public safety, finance, entrance guard and the like.

Back texture feature identification: alfonso Perrez-Escudero et al in 2014 proposed a method for identifying individual animals based on the texture features of the back of a model animal, which indicates that the texture of the back of an animal is similar to the fingerprint of a human being and can be used as a unique marker of a living being. The animal image is converted into a three-dimensional space related to color for individual animal identification, and the method has a good effect in the field of animal food safety tracing.

For example, in conventional small-sized live pig breeding, identification of individual live pigs and determination of health status are still performed by observing individual cages, body shapes, hair colors, sexes, body morphology features, and the like with naked eyes. The defects of the method are mainly exposed in the aspects of high working difficulty, low resolution, low efficiency, high error rate and the like, and the important information of the farm cannot be completely recorded.

In large and medium-sized pig farms, Radio Frequency Identification (RFID) technology has been widely used, and electronic tags are usually designed to be injection-implanted, ear-hang, rumen, etc., and such identification methods themselves are harmful to pigs. The identity of the individual cannot be judged in real time, the data of the individual weight, the feed intake, the water intake and the like cannot be recorded in real time, the cost for manually reading the identity of the individual is high, the efficiency is low, the health condition of the individual live pig cannot be judged in real time, and the anti-counterfeiting capability is insufficient.

The DNA identification technology has long period, high cost and extremely poor real-time property.

In recent years, image recognition-based methods are increasingly used for animal individual recognition, and the physiological characteristics of the technologies for recognition are different, so that the technologies do not need to be marked and are widely applicable. For example: iris recognition, back texture and other feature recognition. However, when the iris recognition technology is applied to scenes such as public safety, finance, entrance guard and the like, the data acquisition object is a person, the behavior of the person is controllable, and the iris image can be shot quickly and the iris database can be established in an express way according to application intentions. But we cannot let the animal have data taken at our will. The complexity and uncontrollable nature of animal behavior make iris recognition techniques unsuitable for individual identification of animals. Therefore, how to solve the above technical problems becomes an effort for those skilled in the art.
