Background
At present, almost all life science experiments such as medicine, biology, pharmacy, chemical industry, livestock, agriculture, industry, environmental protection, commercial inspection, foreign trade, military industry, transportation, aerospace and research of experimental animals are carried out by using experimental animals as human replacement, and the experimental animals are the most precise instruments and cannot be replaced.
Experimental animals are similar to humans in structure, function, and metabolism. Therefore, the preparation method has great effect in the fields of disease research, drug development and the like. In the course of research using experimental animals, it is necessary to monitor information on activities of animals, such as activity intensity, preference of activities, route of activities, and the like. During the feeding or experimentation of experimental animals, the approach or manipulation of humans can result in stress to the animals, and the ideal behavioral and physiological data for the study is generally best obtained with the animals in a non-interfering state. Meanwhile, the animal behavior or physiology change can be shown only by accumulation of a period of time, so that long-time monitoring is needed to obtain analysis and find abnormality. At present, the following 3 kinds of high-frequency monitoring means which do not interfere with the activities of experimental animals are adopted: 1. some behavior detection devices are more than the prior art, such as animal running wheels, mazes, running platforms and other experimental devices, so that animals can independently move in the devices, and data on animal living rhythm, spontaneous movement and the like can be obtained by detecting the number of turns of the animal running wheels driven by the animal moving in unit time in the running wheels. 2. Monitoring by adopting a camera, arranging a camera in an animal raising area, photographing for 24 hours without interruption, and performing data analysis on photographed data by software; the cameras are generally arranged in a plurality, and the normal cameras and the infrared cameras are combined at the same time, so that the problem of insufficient light at night, such as Vium Smart Housing products, is solved.

2. currently, the mainstream means is still camera monitoring, and a high-definition camera and an infrared lens are arranged. The greatest problem of monitoring by using a camera is that because the image is planar, the lens position or the movement of the animal often causes the animal to overlap in the image, which makes it difficult to judge the behavior of the animal, and is limited by the size of the cage and the surrounding devices, if the lens is arranged outside the cage, the animal is possible to move far and near from the lens, and it is difficult to automatically take account of the changes of near and far so as to obtain clear images, and the ideal angle of the lens is limited by the cage and the cage, and some optimal positions may be blocked by the cage and the cage, etc.
