Problems solved by technology

If the LED display screen is used to form a virtual background image, and when the LED display screen is shot through multi-camera cameras, usually only one identical background image can be captured (when the LED display screen only displays one image, The background pictures captured by two or more cameras are exactly the same), and there will be inconsistent shooting effects with the actual scene

Embodiment Construction

[0051] The specific implementation manners disclosed by the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0052] figure 1 It is a flow chart of a video processing method based on a receiving card shown according to an exemplary embodiment, as shown in figure 1 As shown, the method includes:

[0053] In step 101, video source data and shooting requirement information delivered by a sending device are acquired.

[0054] For example, the shooting requirement information is related to the number of cameras enabled during the shooting of the video source, and is used to constrain the playback effect of each frame of video in the video source data. Usually, the target display frame rate of the video source data, the number of times (sessions)...

Abstract

The invention discloses a video processing method, device and system based on a receiving card. The method comprises the following steps: acquiring video source data and shooting demand information issued by a sending device; determining a target display frame rate of the video source data in a playing process according to the shooting demand information, and performing frequency multiplication processing on the video source data according to the target display frame rate; according to the refresh rate of the LED display screen, determining the playing session of each frame of video picture in the video source data after frequency multiplication processing; splitting and recombining each frame of video picture and the corresponding playing session according to the shooting demand information and the playing session to obtain a to-be-played video; and playing the video to be played on the LED display screen. According to the embodiment of the invention, the video source data issued by the sending equipment can be subjected to frequency multiplication processing and splitting and recombination, so that the problem that the shooting effects of cameras at different camera positions are inconsistent when the LED display screen is used as a shooting background is solved, and the shooting effect is ensured to be closer to the display effect of an object in reality.

Description

technical field [0001] The present invention relates to the technical field of LED display screens, in particular to a video processing method, device and system based on a receiving card. Background technique [0002] In the process of shooting movies or broadcasting programs, multiple cameras in different positions (camera positions) will be used for shooting. For actual background shooting, the background captured by cameras in multiple positions will be different due to the three-dimensional characteristics of the real object. There are obvious differences in the shooting effects formed at the positions, that is, the background effects captured by each camera are inconsistent. If the LED display screen is used to form a virtual background image, and when the LED display screen is shot through multi-camera cameras, usually only one identical background image can be captured (when the LED display screen only displays one image, The background pictures captured by two or m...
