Description

一种多机位多角度LED显示屏校色方法及系统 A multi-camera angles LED display color correction method and system

技术领域 FIELD

[0001] 本发明涉及数据显示技术领域,具体涉及一种多机位多角度LED显示屏校色方法及系统。 [0001] The present invention relates to a data display technique, and in particular relates to a multi-camera angles LED display color correction method and system.

背景技术 Background technique

[0002] LED屏幕在节目制作、展示宣传、广告应用中使用非常广泛的应用。 [0002] LED screen in program production, display of publicity, advertising applications use a very wide range of applications. 但多块LED屏在使用过程由于可视角度不同、位置朝向、造型不同、点间距不同,在用摄像机进行拍摄时会有色差,导致观看和拍摄后内容显示效果不能统一融合,有明显的边界线和明暗区别,显示偏色使其不能让所有的屏幕显示出统一一致的拍摄效果。 However, since a plurality of LED screen different viewing angle, toward the position during use, different shapes, different spacing, be color when photographing by the camera, and cause the recording to view display can not be unified fusion, it has a distinct boundary line and the difference between light and dark, color cast that it can not display all of the screen shows a uniform and consistent shooting. 现在市面上的LED屏的颜色调整都是使用前设置的固定值,无法在多机位切换拍摄过程中动态进行匹配调整。 LED color adjustment screen now on the market are fixed values ​​set before use and can not be dynamically switched during shooting in a multi-camera matching adjustment.

[0003] LED显示是用细小的三基色(红、绿、蓝)LED灯组合排列来进行显示内容的,所以在不同的观看角度看到的发光灯组会有不同色差显示,如左侧是看到绿灯部分偏多偏绿色, 右侧看到的蓝灯部偏多偏蓝色,这对观看和拍摄屏幕效果有极大的不良影响。 [0003] LED display with fine three primary colors (red, green, and blue) LED lamp assembly arranged to display content, so the light unit at different viewing angles to see the display color will be different, as is the left see section above normal green light greenish blue lights of the right side to see the bluish ones, which have a great adverse effect on the viewing screen and shooting effect. 摄像机在拍摄LED屏只能在正对屏幕时才能正常显示颜色和色温,在多块屏拼接时无法保证对每一块屏幕都是正对或者统一的角度拍摄,所以会出现“阴阳”屏的现象,大大破坏LED的显示效果和统一画面表现。 Camera shooting LED screen can only be positive for the screen to display normal color and color temperature, while multiple-screen display is no guarantee that are positive for each one unified screen or camera angles, so there will be the phenomenon of "yin and yang" screen, greatly undermined the unity LED display and screen performance.

[0004] 现有的摄像机定位系统有多种方式,包括红外定位,视觉定位,激光定位,超声波定位等,但没有对屏幕显示颜色进行校正的定位跟踪系统。 [0004] The conventional camera positioning system a number of ways, including infrared positioning, visual positioning, laser positioning, ultrasonic positioning, but does not display color correction screen location tracking system.
