| 摘 要： | 提出了一种新的解决扩充现实中遮挡问题的方法。该算法的核心是在每一帧图像中追踪至少四个基准点,构成仿射基,进而对虚拟物体与真实物体之间的遮挡轮廓进行重建和重投影,且在前两帧图像中交互指定这些阻挡轮廓相对于虚拟物体的前后位置,从而解决了扩充现实的阻挡问题。两个典型实例表明,此算法是可行的。

| Abstract: | A new approach for resolving occlusion problem in augmented reality is presented in this paper. The heart of this algorithm is to track at least four fiducial points from frame to frame that construct the affine frame, thus the occlusion contours between virtual and real objects can be reconstructed and reprojected. Further, each contour is labeled as being "behind" or "in front of" in the first two frames, depending on whether it is in front of or behind the virtual object, so the occlusion is resolved. Two typical examples show that the algorithm is feasible for resolving occlusion. |
