在本文中,我们提出了一种新的在线基于视频的渲染(VBR)方法,创建新的视图的场景从未校准的摄像机。我们的方法不需要关于相机的内部参数的信息。为了获得摄像机之间的几何关系,我们使用投影网格空间(PGS),这是由两个基本摄像机之间的极线几何定义的3D空间。其他相机通过这些基础相机之间的三焦点张量配准到相同的3D空间。我们同时重建和绘制新的视图使用我们提出的平面扫描算法在PGS。为了达到实时性,我们在图形处理器(GPU)上实现了所提出的算法。我们成功地创建新的视图图像实时从未校准的相机和结果表明,我们所提出的方法的效率。
In this paper, we present a new online video-based rendering (VBR) method that creates new views of a scene from uncalibrated cameras. Our method does not require information about the cameras intrinsic parameters. For obtaining a geometrical relation among the cameras, we use projective grid space (PGS) which is 3D space defined by epipolar geometry between two basis cameras. The other cameras are registered to the same 3D space by trifocal tensors between these basis cameras. We simultaneously reconstruct and render novel view using our proposed plane-sweep algorithm in PGS. To achieve real-time performance, we implemented the proposed algorithm in graphics processing unit (GPU). We succeed to create novel view images in real-time from uncalibrated cameras and the results show the efficiency of our proposed method.
