Abstract

The invention discloses a method for sports event live broadcast, comprising the following steps: acquiring positioning information of a camera and parameters of a sensor; rendering the broadcast template of three-dimensional graphs in real time according to the positioning information of the camera and the parameters of the sensor, and calculating the display data related to the current live broadcast event in real time, wherein the broadcast template comprises multiple displacement units describing different broadcast attributes; establishing an association relation between the displacement units in the broadcast template and corresponding live broadcast display data, and acquiring the display data of the three-dimensional graphs with well-configured broadcast attributes; receiving the foreground information of the camera, and outputting the three-dimensional display data and the foreground signals in a mixed mode; and utilizing the mixed output signals as color key backgrounds, and corresponding foreground signals as color key foregrounds, and synthesizing and outputting the color key backgrounds and the color key foregrounds. By using the method in the invention, the requirement on current sports event live broadcast can be met, and better virtual combination can be achieved.

Description

technical field

[0001] The invention relates to the technical field of television program production, in particular to a method for live broadcasting of sports events. 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 perspe...
