点评：一种立体视频编码方法，优点在于通过改变量化参数来改变图像的编码质量，从而改变图像的码率，以适应网络传输带宽的变化，在高带宽条件下同时传输左视点基本层码流、左视点增强层码流、右视点基本层码流及右视点增强层码流而获得高质量的视频，而在低带宽条件下仅传输左视点基本层码流和右视点基本层码流，用户端也能正常解码，获得低质量的视频，从而使得本发明方法的网络适应性良好；由于自动立体显示设备能在视角发生变化时通过已有的视点视频合成出对应当前视角的视频，即虚拟视点合成，本方法通过向用户端提供视差场码流，使用户自动立体显示终端能够快速、低复杂度的实现多视点图像的虚拟合成，以满足实时自动立体显示的要求。

Comment: The invention discloses a three-dimensional video encoding method. The method has the advantages that: the encoding quality of an image is changed by changing a quantization parameter, thus changing the code rate of the image, so as to adapt to the changing of the network transmission bandwidth; under the condition of high bandwidth, a left-viewpoint basic-layer code stream, a left-viewpoint enhancement-layer code stream, a right-viewpoint basic-layer code stream and a right-viewpoint enhancement-layer code stream are transmitted at the same time, thus acquiring high-quality videos; under thecondition of low bandwidth, however, only the left-viewpoint basic-layer code stream and the right-viewpoint basic-layer code stream are transmitted, a client can also normally decode and acquire low-quality videos, thus leading good network adaptability of the method; as an automatic three-dimensional display device can synthesize the video which is corresponding to the present viewing angle by the existing viewpoint video when the viewing angle is changed, namely the virtual viewpoint synthesis. The method leads an automatic three-dimensional display terminal of users to be capable of quickly realizing the virtual synthesis of multi-viewpoint images with low complexity by providing the parallax field code stream for the client, thus satisfying the requirement of real-time automatic three-dimensional displaying.
