Method and system for controlling camera based on robot tilt-pan

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. ...

AI Technical Summary

Problems solved by technology

[0004] 1. During the shooting process, since the cameraman does not know the specific position of the virtual objects in the 3D virtual scene, when it is necessary to record a video mainly based on the virtual objects in the 3D virtual scene, since the virtual objects in the virtual scene require virtual The camera parameters are only visible in an appropriate range, and the virtual camera parameters have been bound to the real-time camera parameters of the real camera, so it often happens that the cameraman cannot find the virtual object in the back-feed overlay video, which increases the possibility of repeated shooting sex, reducing work efficiency;

[0005] 2. Under certain conditions, it may be necessary to adjust multiple shooting parameters of the camera at the same time, and the cameraman may not be able to adjust so many parameters at the same time, thus failing to achieve the expected shooting effect;
