s110, acquiring the real-time distance between the animal cabin and the camera.
In this embodiment, when the animal imaging device works, in order to facilitate the experimenter to observe the animal state, the animal imaging device is integrated with a monitoring device, that is, the camera in the embodiment of the application, the camera is used for observing the animal in real time, the camera is arranged on the animal imaging device body, and the animal cabin is located outside the animal imaging device and can be pushed into the animal imaging device body, so that the animal imaging device scans the animal placed on the animal cabin.
When the camera monitors animals, in order to ensure the definition of the monitoring video, the camera needs to have a proper focal length, and then a proper image can be acquired. Based on the optical principle, the focal length of the camera is related to the distance between the camera and the object to be shot and the image distance of the camera, so the embodiment of the application adjusts the focal length of the camera in real time by acquiring the distance between the camera and the animal cabin based on the focal length. Wherein, the camera is a variable focus optical camera.
