Virtual studio implementation method capable of automatically tracking objects

Abstract

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.

Description

technical field [0001] The invention relates to the field of broadcasting and television, in particular to a method for realizing a virtual studio that can automatically track targets. Background technique [0002] The application of virtual studio greatly saves the cost and time of studio construction, and makes scene replacement fast and convenient. [0003] Because the virtual studio uses a computer-generated virtual three-dimensional scene and a method of keying and synthesizing pictures taken by a physical camera. When pushing, pulling, and panning the physical camera, it is necessary to ensure that the virtual camera in the virtual scene also moves accordingly, otherwise, the characters to be photographed will float in the scene. In order to ensure that the virtual 3D scene generated by the computer can be synchronized with the picture captured by the physical camera when the physical camera is pushed, pulled, and panned, and to avoid the situation that people or obje...
