| 摘 要： | 提出了一种基于标识与平面自然特征相结合的三维注册方法.首先利用已知尺寸的标识获取待注册平面的初始三维注册矩阵,在标识被遮挡情况下利用当前帧与前一帧图像间的单应性关系恢复出当前三维注册矩阵.实验结果表明该方法在很大程度上提高了单纯基于标识的三维注册系统的健壮性与可用性.

| Abstract: | A new marker and planar texture-based registration method is proposed.Initial registration matrix can be obtained using known-size marker.Current registration matrix can be calculated using homography between current and previous frame when marker is occluded.Experiment results show that this method improves the robustness and practicability of marker-based registration systems. |
