Method for editing template in real time in virtual studio system

Abstract

The invention relates to the television program recording and broadcasting technology in the field of broadcasting and television, in particular to a method for editing a template in real time in a virtual studio system. The method comprises the following steps: interlinking an editing system and a graphics workstation which have no contact originally in the virtual studio system under recording and broadcasting separation, and enabling the editing system and the graphics workstation to be capable of performing mutual interaction in real time, thereby the editing system is capable of editing a three-dimensional scene template in real time according to the real position information of a camera in a studio. By adopting the method of the invention, in the virtual studio system of recording and broadcasting separation, the security of the recording and broadcasting separation of the virtual studio system can be ensured, and the virtual studio system can edit the three-dimensional scene template in real time according to the real position information of the camera, thereby enabling the broadcasting of programs to be secure and accurate.

Description

technical field [0001] The invention relates to the production and broadcasting technology of television programs in the field of radio and television, in particular to a method for editing templates in real time in a virtual studio system. Background technique [0002] The virtual studio system is a new TV program production system combining computer technology and chroma key technology. It uses the traditional chroma key technology, but breaks through the limitations of the traditional chroma key system and eliminates the problem that the camera cannot move synchronously with the background. The Achilles' heel is that real actors can go deep into the virtual three-dimensional scene and interact with the virtual objects in it in real time. The virtual studio system is mainly composed of three systems: tracking system (also called sensing system), graphics drawing system, and synthesis system. The tracking system is mainly composed of sensors and coding boxes. The graphics d...

Problems solved by technology

Obviously, the separation of production and broadcasting enables the production and broadcasting of 3D scene templates to be completed in different environments, which increases the completeness of program broadcasting and also improves the production efficiency of columns. This is its advantage, but it also has disadvantages For example, sometimes it is necessary to adjust the parameters of the animation key frame in real time according to the position of the host, such as the animation of a 3D object, the effect to be achieved is that the 3D object flies in, flies into the host's head and then rotates 360 degrees before flying This requires facing the host and adjusting the position of the key frame in real time according to the current studio camera. However, the control terminal of the virtual studio system can only perform simple editing of the 3D scene template, which cannot meet the needs. The relatively independent system cannot obtain the camera information in the system in the virtual studio, so the editing system cannot adjust the parameters of the 3D scene template according to the position of the current host, so sometimes the host and the background will appear on the final output 3D scene screen. In the case of misalignment, in order to overcome this situation, users can only manually perform blind adjustments based on experience, but manual operations will cause large errors, which will bring great trouble to program production, and will also reduce program production and broadcasting.
