Problems solved by technology

At present, most cameras are configured to capture video images at the same frame rate as that of the display terminal, that is, the remote control, that is, the capture frame rate of the camera is equal to the display frame rate of the monitor. Therefore, the delay introduced by the capture time determines the display The delay introduced by the time eventually leads to a higher video image transmission delay

Abstract

A method, a system and a device for video data transmission, and a photographic apparatus, said method comprising: collecting an image according to a predetermined frame collection rate, the frame collection rate being greater than a frame display rate at which a display device displays a video image; performing frameskip processing on the collected image to obtain a target video image frame; performing an encoding processing on the target video image frame so that the frame rate of the encoding output is equal to the frame display rate; and sending to the display device the encoding-processed target video image frame. The invention increases the real-time performance of video data transmission by means of collecting a video image at a frame collection rate that is higher than the frame display rate so that the transmission delay of the video data from an aerocraft end to a display end is reduced by reducing the collect delay.

Description

technical field [0001] Embodiments of the present invention relate to video transmission technologies, and in particular, to a video data transmission method, system, equipment, and photographing device. Background technique [0002] In flight systems such as unmanned aerial vehicles, video recording devices such as cameras are generally installed on the unmanned aerial vehicle for capturing and obtaining video data. The video data needs to be transmitted to the receiving display device of the remote controller on the ground in real time, such as a remote controller, to assist the remote control flight. During this process, it needs to go through steps such as video image frame acquisition, compression encoding, wireless transmission, wireless reception, compression decoding, display, etc. The shorter the time for this process, the better, so as to reflect the current flight situation in time to avoid accidents. [0003] Video data is composed of multiple continuous image f...
