Animal movement track identification method and device applied to bright and dark box and medium

The invention discloses an animal movement track identification method and device applied to a bright and dark box and a medium, and the method comprises the steps: obtaining a video stream, and obtaining video frames which are continuous in time according to the video stream; extracting an animal target from each video frame, and determining a plurality of target points based on the animal target; determining a geometric center point of the animal target according to the plurality of target points and determining coordinates of the geometric center point; and connecting the coordinates of the geometric center points determined in the video frames in continuous time to obtain an animal movement track. The observation time, the shuttling frequency, the incubation period, the open box activity time, the open box activity time percentage, the dark box activity time, the dark box activity time percentage, the total distance, the open box activity distance and the dark box activity distance can be extracted throug
