三线性约束及其在图像合成中的应用

通过对极几何关系及三线性约束关系立体视觉中参考视点之间和参考视点与虚拟视点之间的摄像机几何限制，把参考图像中的像素点直接转移到虚拟图像的对应点中去，即通过已得摄像机视点位置上的所得场景的图像，计算该摄像在其他各个视占位置上所得到的该场景的国邓列，表明，该方法简单、有效，对计算机视觉中的运动估计、低比特率视频编码、虚拟现实和动画制作中都有很发的应用价值。

Trilinear constraint and its application in image synthesis

This paper first presents the geometric constraints between the reference view and the virutal view in stereo vision by using both epipolar geometry and trilinearity. Then the image pixels from the original images which are reference images are transferred into the virtual images which are observed from a different viewing position. By using the reference images that we have obtained at the different camera positions which are known, we calculate other images which would be obtained from other camera positions which we call the virtual camera positions. This technique can be widely used especially in virtual realities, or high rate video vompression, and the experiments show this method is simple, and highly efficient and is of great potential practical value.
