Characteristics of virtual studio

Virtual studio system is a new TV program production system with the rapid development of computer technology and the continuous improvement of color key technology in recent years. In the virtual studio system, the working state information of the camera is transmitted to the graphics workstation, and the computer can get the distance and relative position between the foreground object and the camera, thus calculating the most suitable size and position of the virtual scene, and generating the three-dimensional model of the virtual scene according to the requirements. Video live broadcast adopts the principle of color keys, and puts the host or actor in front of the blue background curtain to perform, and then separates the host from the blue background by using the color key function on the switchboard, and perfectly blends with the three-dimensional model generated by the computer in real time, forming an imaginary new environment and atmosphere, which does not exist in reality, but plays the role of a studio on the TV screen, and finally gets a picture that seamlessly blends the real shot characters with the virtual scene.
