Embodiment Construction

[0029] 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.

[0030] 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 live-broadcast control method for a virtual sports system, comprising the following steps: processing the related display data obtained by the positioning of a camera in the live broadcast of contest; invoking a prearranged broadcasting template; establishing the relationship between a replacing unit of the template and the corresponding live-broadcast display data; defining the corresponding broadcast property by the replacing unit; and broadcasting the corresponding template at the corresponding time according to the corresponding contest. The method and the device have the advantages of simplifying the operation of the related technicians and improving the living-broadcast safety.

Description

technical field [0001] The invention relates to the technical field of television program production, in particular to a live broadcast control method of a virtual sports system and a live broadcast control device of a virtual sports system. 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, ...
