Problems solved by technology

[0004] However, in practice, a situation that may arise is that during a live broadcast of a game, on the one hand, it is necessary to render the 3D scene for broadcast, and on the other hand, it is necessary to calculate the real-time 3D data of the current offside line and other items that require manual intervention, which affects the rendering quality. Efficiency and safety of live streaming

Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The embodiment of the present invention is mainly applied in the virtual sports technology further developed based on the virtual studio technology. Virtual sports technology is to superimpose static or animated 3D images on the screen of live sports competition programs. No matter whether the camera is moving or not, the graphics can be fixed at a certain position, making it visually feel that these 3D graphics are part of the live broadcast. The virtual sports system has a live event tracking function, which can display the actual distance, height and speed in grass, track and field, football field, snow, water or 3D space. Advertisements are displayed and new or animated TV commercials can be overlaid on top of actual c...

Abstract

The invention discloses a virtual sports system in a split mode, which comprises a second graphic workstation and a first graphic workstation, wherein the second graphic workstation comprises a video camera positioning module and an interface module, the video camera positioning module is used for initially positioning the current video camera, and the interface module is used for forming a communication interface between the second graphic workstation and the first graphic workstation; and the first graphic workstation comprises a rendering module which is used for rendering a three-dimensional scene model according to the positioning information of the video camera. By using the virtual sports system in the split mode, the flexibility of control, the efficiency of rendering and the safety of live broadcasting can be increased.

Description

technical field [0001] The invention relates to the technical field of TV program production, in particular to a virtual sports system in separate mode. Background technique [0002] The virtual sports system is developed from the virtual studio technology, which belongs to a very important branch of the virtual studio technology. Virtual studio is a unique TV program production technology developed in recent years. Its essence is to digitally synthesize the virtual 3D model made by the computer and the moving images of the objects captured by the camera in real time, so that the object images and the virtual background can change synchronously, so as to achieve the fusion of the two to obtain a perfect composite picture. The virtual studio technology is based on the traditional chroma keying technology, making full use of computer 3D graphics technology and video synthesis technology, according to the position and parameters of the camera, so that the perspective relations...
