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.

The invention discloses a virtual studio implementation method capable of automatically tracking objects. The virtual studio implementation method comprises the following steps: selecting a high-resolution real camera and setting a camera position so that the real camera is capable of getting a comprehensive shot of the whole range of the activities of objects without any operation; creating a virtual scene and an image matting plane; setting the position of a virtual camera; performing chroma key image matting on a picture picked up by the real camera and mapping the images of the objects into the image matting plane to form mapped images; calculating the positions of the objects during activities in a real scene by use of an image identification module; generating a group of attitude data based on the position information and controlling the operation of the virtual camera through the attitude data; generating a scene image by an image rendering system based on the picture picked up by the virtual camera; and synchronizing the mapped images and the scene image into an image for final presentation and generating a virtual studio to play videos. The virtual studio implementation method capable of automatically tracking the objects is capable of enabling the installation and debugging of the virtual studio to be simple and fast, and also capable of greatly saving cost.

Method for tracking virtual camera in three-dimensional scene

The invention discloses a determination system and method for position and posture of a video camera in a virtual studio. The system comprises a foreground video camera to be determined, and a support device for fixing the foreground video camera; the determination system further comprises at least one light emitting device, at least one detection video camera and a server. The at least one light emitting device is mounted on the support device; the at least one detection video camera is mounted at the roof and/or the surrounding walls in the virtual studio, and is used for performing real-time image acquisition on optical patterns generated by the light emitting device, within an activity area of the foreground video camera; and the server is used for extracting characteristic points according to the images acquired in real time by the at least one detection video camera, calculating position of the light emitting device according to the extracted characteristic points, and then, determining the position and the posture of the foreground video camera according to a position relation between the light emitting device and the foreground video camera. A technical scheme, carrying out the system and the method disclosed by the invention, can be suitable for the video cameras of any studio, is convenient for fixing and detaching the video camera, and is accurate and steady.

The invention discloses an initial positioning method for a camera in a virtual studio system. A light blue rectangular frame of specific size is coated on a blue box wall in the shooting right front of the camera. The method comprises the following steps of: aligning the camera with the rectangular frame to shoot a foreground image; extracting angular point coordinates of the rectangular frame in the foreground image; and calculating an initial attitude matrix of the current camera by iteration according to the angular point coordinates. By a simple and feasible mode, the initial positioning of the camera in the shooting process can be more convenient and quicker.

Initial positioning method and device for camera in virtual studio system

A positioning method of instant initialization in virtual studio system includes setting virtual video camera ( VVC ) coordinate on original of coordinate in 3D virtual space , enabling to set real video camera ( RVC ) position at any location according to its 3D perspective relation , calculating out RVC movement increment relative to initial location by tracking server and using it as movement increment of VVC for ensuring identical movement relation of both said cameras to make VVC movement have no relation to initial location of RVC , using RVC perspective relation as base to use VVC to adaptive ?C match to RVC for finalizing initial positioning of the two
