| 摘 要： | 根据多视点视频中的几何约束关系,提出了一种基于图像的新视点重建方法,能够根据所选择方位重建虚拟视;针对虚拟视中合成误差,提出了基于平面扫描的校正方法,最终获得了主观质量和客观质量均优于传统方法的虚拟视。

| Abstract: | Based on the geometrical limitations between multi-view videos,we propose a virtual view reconstruction method based on image-based rendering(IBR),which can synthesize virtual views according to the new positions chosen by viewers.Focusing on the errors in virtual view synthesis,we present a correction scheme based on plane-sweep algorithm.Experimental results show that our proposed method can obtain better quality of virtual views than traditional methods in both objective and subjective comparisons. |
