针对虚拟视点绘制中由于区域暴露引起的空洞问题，提出一种基于图陣金字塔修复的虚拟视点绘制方法。利用视点变换方程生成虚拟视点，对含有空洞的视点采用图陣金字塔修复进行处理，设计含有深度陠的权值函数，在深度的约束下进行高斯加陭零的滤波和下采样，对低分辨率图陣的上采样，利用采样的图陣信息对空洞进行填充。实验结果证明，该方法得到图陣的主观视觉效果和峰值信噪比计算结果优于传统的非对称高斯滤波算法，且图陣绘制的虚拟视点不失真，可抑制物体边缘处的伪陣生成。

Aiming at the problem of the holes caused by exposing regions in virtual viewpoint rendering, this paper proposes a virtual viewpoint rendering method based on image pyramid inpainting. The viewpoint warping equation is utilized to generate a virtual viewpoint. The image pyramid method is employed to restore holes inside the warped view. Depth information is incorporated into the cost function for Gaussian plus zero-canceling filter and down-sampling, low resolution image can be up-sampling, the expanded image information can be used to fill the holes. Experimental results show the proposed algorithm has superiority in both subjective details and the results of Peak Signal to Noise Ratio(PSNR), and virtual viewpoint of image rendering has not distortion, it can restrain the generation of false image in the edge.
