Method of maintaining accuracy in a 3D image formation system
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 system for maintaining accuracy in a 3D image formation includes a multi-screen display color correction system, a multi-screen display color correction system comprising a large-size screen server, a video camera and a large-size display screen wherein the large-size screen color correction server includes an image input module, a position data module, a comprehensive color correction server and an image output module.
1. A method of maintaining accuracy in a 3D image formation system, comprising:
correcting a color on multi-screens; the color correction including the following steps:
determining position coordinate information of a video camera and images of multiple display screens taken by the video camera;
selecting one of the multiple display screens as a standard screen, conducting color correction on display content of the remaining multiple display screens using the images collected by the video camera and screen correction parameters, wherein to achieve a same display effect with that of the standard screen;
storing the screen correction parameters conducted to the other screens;
determining a change time of a position of the video camera, wherein if a time is less than or equal to N, then changing the position of the video camera and repeating the steps above, if the time is greater than N, moving on to the steps below; and
using matched curves of an algorithm from the stored screen correction parameters to guarantee a gain of screen color correction parameters of the video camera in different positions, wherein the images of the multiple display screens collected by the video camera in different positions present the same display effects, wherein when the video camera is in different positions, conducting color correction on the multiple display screens according to the screen color correction parameters gained by the position coordinate information and the matched curves.
2. The method as recited in claim 1 , wherein the position coordinate information includes coordinate information and camera angle information of the video camera.
3. The method as recited in claim 1 , wherein the standard screen is selected by selecting one of the multiple screens that faces directly against the position of the video camera.
4. The method as recited in claim 1 wherein N equals 5.
5. The method as recited in claim 1 wherein the same display effect is a condition that the images of the multiple display screens collected by the video camera in different positions and from different angles all present a same color and color temperature.
