多视点视频编码是当前视频编码领域的研究热点之一。在有限的网络带宽下，合理的码率分配可以提高视频主观视觉质量。本文提出一种基于结构相似度的码率分配方法，首先对视频帧提取基于结构相似度的显著图，然后结合显著图对重要宏块和非重要宏块分配不同的QP值，以达到码率分配的目的。实验结果表明，本文方法在有限的带宽下能有效的提高多视点视频的视觉主观质量。

Multiview video coding is one of the hotspots in the field of video coding.In the limited network bandwidth, reasonable bit allocation can improve the video subjective quality. A rate allocation method based on the image structural similarity is proposed in this paper, firstly, a saliency map based on structural similarity is extracted, then the important macro block and non important macro block is set by different QP value.The experimental results show that,this method can effectively improve the visual quality of multiview video under limited bandwidth.
