Multi-viewpoint switched shooting system and method
A method and system for a displaying content that makes LED real-time 3D displays possible. The 3D image formation includes multi-screen display color correction and multi-camera infrared positioning technology. The present invention presents the display effects of a simulation environment in a better way through switching and moving and ensures that while in movement, the display effects of LED screens taken by video cameras from different angles can be maintained the same, so as to create a vivid simulation environment for television programming and film shooting. The multi-viewpoint switched shooting system and method based on the infrared positioning system includes a multifaceted irregular screen, a video splicer, a 3D rendering server, an infrared positioning system, a motion-capture computer, a Network switch and a multichannel control server.
1. A system for a multi-viewpoint switched shooting based on an infrared positioning system, the multi-viewpoint system including a multifaceted irregular screen, a video splicer, a 3D rendering server, an infrared positioning system, a motion-capture computer, a network switch and a multichannel control server;
wherein the multifaceted irregular screen is used to constitute a space for shooting, the video splicer is installed in a back of the multifaceted irregular screen, the 3D rendering server, the multichannel control server and the network switch are connected with the multifaceted irregular screen respectively and used to process images displayed on the multifaceted irregular screen;
wherein the infrared positioning system is installed above the multifaceted irregular screen and is connected with the motion-capture computer to track a video camera while shooting.
2. The system as recited in claim 1 wherein the infrared positioning system includes several infrared cameras installed above a space for shooting with several video cameras, the video cameras being placed in a front of the space for shooting and each video camera being equipped with several infrared markers on a head each of the video cameras.
3. The system as recited in claim 2 wherein the infrared positioning system is used to gather position parameters of the infrared markers on each of the video cameras.
4. The system as recited in claim 3 wherein the motion-capture computer is used to correct a difference in value between the infrared markers and a lens of the video cameras based on the position parameters of the infrared markers to get coordinate information of the video cameras and transmit it through the network switch to the 3D rendering server and the multichannel control server, the 3D rendering server is used to output a display of 3D space images, and the multichannel control server is used to match the coordinate information of the video cameras to a virtual space for use and matches the coordinate information of the video cameras with coordinate information of the virtual space.
