Embodiment Construction

[0021] In the existing virtual fusion technology, the real cameras are all controlled by humans. Since the cameraman does not know the specific positions of the virtual objects in the 3D virtual scene, when it is necessary to record a video based on the virtual objects in the 3D virtual scene When the virtual object in the virtual scene requires the virtual camera parameters to be visible in an appropriate range, and the virtual camera parameters are bound to the real-time camera parameters of the real camera, it often happens that the cameraman cannot find it in the superimposed video. The situation of virtual objects increases the possibility of repeated shooting and reduces work efficiency.

[0022] In order to solve the above problems, the embodiments of the present invention provide a camera control method and system based on a robot pan / tilt, so as to improve the efficiency and accuracy of shooting.

[0023] First, an embodiment of the present invention provides a camera...

Abstract

The invention discloses a method and a system for controlling a camera based on a robot tilt-pan, relates to the field of television broadcasting, and is used for improving efficiency and accuracy of camera shooting. The method includes that broadcast materials prepared by a material making module of the controlling center are loaded by a broadcast controlling center; the broadcast materials comprise visual scenario information and animation information used for describing moving manners of objects in visual scenarios and camera shooting manners of a visual camera; preset visual camera shooting parameters used for adjusting the visual camera are determined by the broadcast controlling center according to the animation information; the format of the preset visual camera shooting parameters is transferred into preset real camera shooting parameter used for controlling a real camera by the broadcast controlling center; the preset real camera shooting parameters are sent to the robot tilt-pan by the broadcast controlling center; and the real camera is adjusted by the robot tilt-pan according to the preset real camera shooting parameters.

Description

technical field [0001] The invention relates to the field of television broadcasting, in particular to a camera control method and system based on a robot PTZ. Background technique [0002] Under the existing technical conditions, the use of virtual reality technology can combine real scenes (real video data captured by real cameras) with 3D virtual scenes (virtual video data generated by the rendering engine according to the 3D virtual scene information and animation information contained in the playback material). ) are superimposed to obtain the video after the fusion of the real scene and the 3D virtual scene. [0003] In short, the video fusion of virtual reality is to obtain the real-time camera parameters of the real camera, and modify the virtual camera parameters of the virtual camera in the 3D virtual scene through the interface of the rendering engine. The purpose is to make the camera parameters of the virtual camera and the camera parameters of the real camera. ...
