Abstract: The invention provides a system and method that reduces the precision of the manual alignment process. Users select correspondences between projectors or components of a projector, to form a common coordinate. Using models of the display system, and projectors, the common coordinate system can be mapped quickly to the entire display. The process avoids a need to measure screen points, and allows the user to move significantly fewer points. Alternatively, the invention allows introduction of machine-vision style algorithms into manual calibration techniques to improve performance. This overcomes the tediousness of prior systems by introducing models of the display into the manual alignment process, allowing selection of a small number of points on each projector, and avoiding selection of precisely measured screen points. The system conversely finds correspondences between projectors, allowing mapping of the projectors into a common coordinate system, and quick warping of the coordinate system to the screen.

Abstract translation: 本发明提供了降低手动对准过程精度的系统和方法。 用户选择投影机或投影机组件之间的对应关系，形成一个共同的坐标。 使用显示系统和投影机的型号，可以将公共坐标系快速映射到整个显示屏。 该过程避免了测量屏幕点的需要，并允许用户移动明显更少的点。 或者，本发明允许将机器视觉风格算法引入到手动校准技术中以改善性能。 这通过将显示器的模型引入手动对准过程来克服现有系统的繁琐，允许在每个投影仪上选择少量点，并避免选择精确测量的屏幕点。 系统反而发现投影机之间的对应关系，允许将投影机映射到公共坐标系中，并将坐标系快速变形到屏幕上。
