摘要
虚拟视点合成是虚拟现实、多视点视频等领域中的关键技术,本文实现了一种基于深度图绘制(D IBR)的虚拟视点合成算法,并对合成图像中的遮挡与空洞问题进行了深入分析与研究,利用空间线投影方法解决了由于遮挡造成的误投影问题,同时使用视点间双向插值算法实现了空洞填补。实验结果证明,本文算法能够合成令人满意的虚拟视点图像。
The virtual view synthesis is a key technique in virtual reality and multi -view video. This paper discusses the realization of virtual view synthesis algorithm based on DIBR. The paper also makes an analysis of occlusion and holes problem in the synthetic images. In addition, a three - dimensional space lines projecting method is proposed to resolve the problem of synthesis error and a bi - directional interpolation is used to fill the holes. The experimental results show that the virtual view synthesis algorithm based on DIBR can obtain satisfactory virtual view images.
