摘要
本文将配准技术与插值算法相结合,通过对场景中运动物体的时间帧配准、时间域和空间域的插值,生成了任意时刻、任意视点处的渲染图像,完成对运动物体时空域的光场渲染。该研究结合并推广了传统光场渲染方法,放宽了对场景的要求。和现有的方法相比,该方法适应性强、鲁棒性好。实验结果进一步体现了该方法较好的应用前景与可操作性。
Propose an algorithm which can deal with a dynamic scene based on light field rendering we call it dynamic light field rendering（DLFR）. This algorithm mainly follows these two steps： Firstly, we use image registration algorithm to match each two neighbor image frames of the video, find the motion vector between them and do the interpolation in temporal domain. Secondly, do interpolations in spatial domain. Finally we can get the frame at any time from any view point to the scene. The algorithm is simple and easy. And also it can achieve a better image quality.
