摘要

介绍了动态场景的视图插值问题。我们对这个问题的解决方案扩展了视图变形的概念,并保留了该方法的实际优点。我们特别关注在不同时间捕获的两个参考视图之间的插值,以便在视图被捕获之间存在缺失的时间间隔。由我们的算法产生的合成插值描绘了一个可能的物理有效版本,在消失的时间里,场景中发生了什么。假设原始场景中的每个物体都经历了一系列的刚性平移。动态视图变形可以与宽间隔的参考视图、稀疏点对应和未校准的相机一起工作。当摄像机到摄像机的变换确定后,合成插值将在世界空间中描绘沿直线匀速轨迹运动的场景物体。

Interpolating view and scene motion by dynamic view morphing
We introduce the problem of view interpolation for dynamic scenes. Our solution to this problem extends the concept of view morphing and retains the practical advantages of that method. We are specifically concerned with interpolating between two reference views captured at different times, so that there is a missing interval of time between when the views were taken. The synthetic interpolations produced by our algorithm portray one possible physically-valid version of what transpired in the scene during the missing time. It is assumed that each object in the original scene underwent a series of rigid translations. Dynamic view morphing can work with widely-spaced reference views, sparse point correspondences, and uncalibrated cameras. When the camera-to-camera transformation can be determined, the synthetic interpolation will portray scene objects moving along straight-line, constant-velocity trajectories in world space.
