基于视频投影的增强现实应用程序要想有效，就必须跟踪移动目标，并确保即使目标移动，显示屏也保持对齐，但投影可能会严重改变它们的外观，以至于传统计算机视觉算法失效。当前的解决方案将显示的内容视为干扰，并且很大程度上取决于与可见光正交的信道。他们不能直接将投影仪图像与真实世界的表面对齐，即使这可能是实际的目标。相反，我们建议对投影仪发出的光进行建模，并将其反射到相机中，并将显示的内容视为对直接对齐有用的附加信息。使用彩色摄像头，我们实现的软件成功地跟踪亚像素精度的漫反射性能的平面表面，平均每秒8帧的商品硬件，为未来的增强提供了坚实的基础。
Augmented reality applications based on video projection, to be effective, must track moving targets and make sure that the display remains aligned even when they move, but the projection can severely alter their appearances to the point where traditional computer vision algorithms fail. Current solutions consider the displayed content as interference and largely depend on channels orthogonal to visible light. They cannot directly align projector images with real-world surfaces, even though this may be the actual goal. We propose instead to model the light emitted by projectors and reflected into cameras and to consider the displayed content as additional information useful for direct alignment. Using a color camera, our implemented software successfully tracks with subpixel accuracy a planar surface of diffuse reflectance properties at an average of eight frames per second on commodity hardware, providing a solid base for future enhancements.
