Intelligent virtual studio system

Abstract

The invention relates to the technical field of a virtual studio system, and particularly relates to an intelligent virtual studio system. The intelligent virtual studio system comprises an SDI video switching device, an image matting and synthesizing device, a nonlinear server, an SDI monitor, a streaming media server, a storage array, a central processing unit, a time delay unit, a camera tracking system, a virtual camera control device, a graphic computer, a background video, a premonitor, a character generator, an internet and a user television. According to the intelligent virtual studio system disclosed by the invention, shooting and image pickup are carried out by utilizing a foreground camera and a camera; after the SDI video switching device and the central processing unit carry out processing, sound effect rendering is carried out by the time delay unit; the virtual camera control device further carries out processing on an obtained image; after the graphic computer carries out graphic arrangement, the image is overlapped with various sceneries together by the image matting and synthesizing device so as to form a miraculous artistic effect; the storage array is used for storing video data; and the streaming media server is matched with the internet to implement remote viewing on a virtual studio. The intelligent virtual studio system disclosed by the invention is simple in structure, implements intelligent control, is higher in user experience, and has great creativity.

Description

technical field [0001] The invention relates to the technical field of a virtual studio system, in particular to an intelligent virtual studio system. Background technique [0002] Virtual studio is a unique TV program production technology developed in recent years. Its essence is to digitally synthesize the virtual three-dimensional scene produced by the computer and the moving images of the characters captured by the TV camera in real time, so that the characters and the virtual background can change synchronously, so as to realize the seamless fusion of the two to obtain a perfect composite picture. The virtual studio system uses camera tracking technology to obtain real camera data and combine it with the computer-generated background. The background imaging is based on the lens parameters obtained by real camera shooting, so it is completely consistent with the three-dimensional perspective relationship of the actors, avoiding Feeling unreal and unnatural. Since the ...

Problems solved by technology

[0003] The above-mentioned patent documents can be perfectly integrated with the three-dimensional graphics generated by the computer to form an environment and atmosphere that does not exist in reality but also functions as a studio on the TV screen; it can free the TV director from time, space and prop production. Free creation in a wide imaginary space; it can greatly improve the TV station's ability to create and produce programs, expand the space for TV programs, and reduce the cost of program production. However, how to provide a simple structure, The intelligent virtual studio system with convenient operation, lower cost, intelligent control and higher user experience lacks technical solutions
