Problems solved by technology

[0003] In the prior art, chroma key synthesis usually simply superimposes the foreground image collected by the camera and the 3D virtual scene generated by the computer, that is, the display of the synthesized picture only has two layers of the foreground image and the 3D scene. However, in the live broadcast of the virtual sports system In the screen, it is often necessary to place a virtual 3D scene between two layers of foreground images. For example, it needs to be displayed that athletes and referees are on virtual objects, and these virtual objects are on grass or water. The existing technology is difficult to achieve the effect of this combination of virtual and real

Embodiment Construction

[0025] 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.

[0026] 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 an increased virtuality and reality combination degree, which comprises a first graphics workstation and a chroma keyer. The first graphics workstation comprises a camera signal receiving module, a three-dimensional graphics acquisition module and a hybrid output module, wherein the camera signal receiving module is used for receiving a foreground signal acquired by a camera; the three-dimensional graphics acquisition module is used for receiving the three-dimensional graphics data of live broadcasting of a current competition; and the hybrid output module is used for performing hybrid output according to the three-dimensional graphics data and the foreground signal. The chroma keyer is used for performing synthetic output by taking a hybrid output signal as a chroma keying background and taking a corresponding foreground signal as a chroma keying foreground. The virtual sports system can satisfy the needs of live broadcasting of the current sports competition and achieve a higher virtuality and reality combination degree.

Description

technical field [0001] The invention relates to the technical field of TV program production, in particular to a virtual sports system that increases the degree of combination of virtual reality and reality. 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 para...
