在增强现实中，基于标记的跟踪是用于相机姿态估计的最常见方法。大多数标记都是黑色和白色图案，这些图案在视觉上很显眼，但可以使用图像修复方法将它们从视频中隐藏起来。在本文中，我们提出了一种计算效率高的方法来实现这一点。我们使用高分辨率的隐藏纹理，它只被捕获和生成一次。为了捕捉光照、反射和曝光的连续变化，我们还在每帧上计算一个非常低分辨率的纹理。粗纹理和细纹理被组合以获得详细的隐藏纹理，该隐藏纹理对变化的条件作出反应并且在移动的电话环境中有效地运行。
In augmented reality, marker-based tracking is the most common method for camera pose estimation. Most of the markers are black and white patterns that are visually obtrusive, but they can be hidden from the video using image inpainting methods. In this paper, we present a computationally efficient approach to achieve this. We use a high-resolution hiding texture, which is captured and generated only once. To capture continuous changes in illumination, reflections and exposure, we also compute a very low-resolution texture at each frame. The coarse and fine textures are combined to obtain a detailed hiding texture which reacts to changing conditions and runs efficiently in mobile phone environments.
