Automatic broadcast and control virtual sports system

Abstract

The present invention discloses an automatic broadcast and control virtual sports system, which comprises: a first graphic workstation, wherein the workstation comprises a rendering module, used for calculating a camera attitude matrix according to sensing parameters and positioning information of a camera to render a broadcast template of a three dimensional scene; a second graphic workstation, wherein the workstation comprises a camera positioning module, used for performing initial positioning on the current camera; a data processing module, used for calculating correlative display data in live sports events according to the sensing parameters and the positioning information of the camera; a data transmission module, used for transmitting the live display data to a broadcast control module; the broadcast control module, wherein the module comprises an association sub-module connected with the second graphic workstation; a broadcast and control information generation sub-module, used for generating broadcast control information of the live display data having the corresponding broadcast attributes when the broadcast is controlled; and a transmission sub-module connected with the first graphic workstation.

Description

technical field [0001] The invention relates to the technical field of television program production, in particular to an automatic broadcast control 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, according to the position and parameters of the camera, so that the p...

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

[0005] In addition, during the live broadcast of the event, relevant technical personnel are often required to modify the corresponding display templates for different games, which not only makes the operation cumbersome, but may also affect the live broadcast due to the misoperation of the technical personnel.
