Virtual Studio Technology Shading To Achieve

Virtual studio system,which is a hotspot research area in video frequency production field nowadays ,its mostly research content is :shoot the histrionic' s perform in blue box,then by using chroma key,synthesize it with virtual scene produced by computer.The paper' s mostly work is to achieve the cover relation in the virtual studio,the major research is for locking the real camera and the virtual camera,The paper solve the technique problem such as :Calibration for electromechanical camera tracking,by transferring coordinate,lock the movement of the virtual camera and the real camera;present an algorithm to carry out the function of the unlimited blue box,resolve the matter that the floor of virtual studio is small;achieve the relation of cover in the three dimension scene,which make the virtual studio can give the impression of the histrionic' s interlude perform in virtual scene,...
