摘要

经典的视觉船体实现是建立在物体被所有摄像机完全可见的假设之上的。这限制了要监视的卷的大小。通过在经典的占用描述中增加可见性,我们将每个摄像头的影响限制在它所关注的子体量上。感兴趣的体积的不同部分由不同的相机子组重建。在分布式重建系统中,感兴趣的量不再受摄像机位置的限制,而是受设备成本和系统延迟的限制。我们演示了使用针孔相机的实时系统和在移动的火车上用鱼眼镜头获得的序列的可视性的使用。

Monitoring large volumes of interest by using voxel visibility
Classical visual hull implementations are fonded on the hypothesis that the object is entirely visible by all the cameras. This limits the size of the volume to monitor. By adding visibility to the classical occupancy description, we limit the impact of each camera to the sub-volume of interest viewed by it. Different parts of the volume of interest are reconstructed by different sub-groups of cameras. Within a distributed reconstruction system, the volume of interest is no more constrained by camera placement but by the cost of the equipment and the latency of the system. We demonstrate the usage of visibility with a real time system using pinhole cameras and with sequences acquired on board of a moving train with fish eye lenses.
