在本文中，我们提出了一个系统，减少现实与多手持摄像机系统。在本文中，我们假设这样的情况下，同一场景被捕获多个手持摄像机，但一些对象遮挡的场景。在这种情况下，我们提出了一种方法，用于合成图像的每个摄像机中的遮挡对象被减少的支持不同的摄像机，捕捉相同的场景在不同的视点。在所提出的方法中，我们使用的AR标签标记来校准多个摄像机，使在线处理可以成为可能。通过使用AR标签，我们计算了每个摄像机的成像平面与近似为平面的目标场景之间的单应性。单应性用于扭曲平面区域以合成观看者的图像，所述观看者的图像仅包括不能近似为平面区域的客观场景而没有遮挡对象。我们证明，观众的图像没有遮挡对象可以合成为每个摄像机在线，即使所有的摄像机都自由移动的所有摄像机每个摄像机的关系。
In this paper, we present a system for Diminished Reality with multiple handheld camera system. In this paper, we assume a situation such that the same scene is captured with multiple handheld cameras, but some objects occlude the scene. In such case, we propose a method for synthesizing image for each camera in which the occluding objects are diminished by the support of the different cameras that capture the same scene at the different viewpoints. In the proposed method, we use the AR-Tag marker to calibrate the multiple cameras, so that online process can be possible. By the use of AR tag, we compute homographies for between each camera’s imaging plane and the objective scene that is approximated as a planar in this research. The homography is used for warping the planar area for synthesizing the viewer’s image that includes only the objective scene without the occluding object that cannot be approximated as a planar area. We demonstrate that the viewer’s image without the occluding object can be synthesized for every camera on-line, even though all the cameras are freely moving for all cameras each camera that relates.
