摘要
针对应用深度图像的绘制(DIBR)技术生成的虚拟视点图像中存在的空洞问题,提出了一种基于DIBR的高质量的虚拟视点图像绘制算法。先由多幅参考图像分别生成同一虚拟视点位置的多幅目标图像,将这些虚拟视点目标图像融合为含有少量空洞的目标图像,然后采用逆映射的方法在多幅参考图像中找到这些剩余少量空洞的对应内容并填充空洞,从而生成高质量的虚拟视点图像。实验结果表明最后生成的虚拟视点图像具有良好的视觉效果。
According to the hole problem appearing in virtual view images, a new virtual view images with high image quality rendering algorithm based on Depth Image Based Rendering (DIBR) is proposed. Firstly, several images of the same virtual viewpoint are created by multiple reference images, and these virtual view images are merged into one target image with fewer holes. Then the correspondences in multi-reference images for those remaining holes are found to fill the holes by inverse warping, and a virtual view image with high quality is generated finally. Experimental results show that the generated virtual view images have favorite view effect.
