Device screen dynamic performance test method, device, system, device and medium

The invention provides an equipment screen dynamic performance test method, device, system, equipment and medium, and the method comprises the steps: collecting a plurality of continuous image frames of a screen display interface in the process of executing dynamic operation on a tested equipment screen, carrying out the differential operation of a to-be-processed image frame and a previous image frame, associating the obtained differential frame with the image frame, and carrying out the dynamic performance test on the tested equipment screen. The method comprises the following steps of: obtaining different image frames corresponding to different image frames, screening the image frames according to the difference frames to obtain a plurality of target image frames, fitting the difference frames corresponding to all the target image frames to obtain difference frame change data, and determining a starting image frame and an ending image frame from all the target image frames according to valley points in the
