The equipment required to establish a virtual studio is as follows:

1, blue box or green box;

2. Studio lighting;

3. Acoustical decoration of studio;

4. camera;

5. Software and equipment for virtual scene design and generation;

6. Healthy color;

12, black field generator;

13, video switcher.

Part of a virtual studio

Virtual studio is a comprehensive video processing technology, which generally consists of the following five parts:

1. foreground system: it consists of hardware equipment such as camera (including CCU), multi-channel program-controlled switcher, video and audio delay device, etc.

2. Background system: It is mainly composed of computer, 3D real-time rendering board and software, and needs dynamic infinite blue box function. In order to play the feedback signal in real time, it also has the function of collecting and processing external input video signals. At the same time, tracking data reading, depth of field recognition data reading, alpha key rendering and other functions are indispensable.

3. Tracking system: There are two main ways to identify the tracking system, one is pattern recognition, and the other is sensor. The tracking system mainly completes the collection and processing of physical camera position data, and distributes it to the virtual camera of the system in real time.

4. Image synthesis system: Image synthesis is mainly realized by color keys, which are divided into digital color keys and analog color keys.

5. Depth of field identification system: High-end systems are generally equipped with depth of field identification systems, including sensors and data acquisition and processing equipment (computers, boards, etc.). ) Get the position information of the program host in the foreground blue box in real time, so as to automatically match the depth of field relationship and mutual occlusion relationship between the program host and the virtual scene.
