【摘要】 文章介绍了一种新的基于代数约束的图像生成方法，用于从两幅不同角度的参考图像来生成另一幅新的视角图像，即二次投影。该方法在极线几何的基础上，通过研究物体在三个不同透视投影平面上对应点之间的相互关系，得到描述不同图像上对应点关系的一个三线性张量。由此张量和参考图像便能得到新图像和参考图像之间的关系，进而就可以生成新的视角图像。和其他基于图像的二次投影方法相比，这里仅需要两幅参考图像，且实现方法简单快速。实验给出了令人较满意的效果。更多还原

【Abstract】 In this paper,A new technique for the image rendering based on algebraic constraint is proposed. It is used to render another novel view from two reference images of different location,which is called re-projection. By studying the geometry relationship among the corresponding points on three different projective plane based on epipolar geometry and the trilinear tensor constraining the corresponding points of different view is obtained. From this tensor and the corresponding relationship between the reference images,the relationship between the novel view and the reference images can be obtained and the novel view is thus obtained. Comparing with other image re-projection methods,this method needs only two reference images and the implementation is easy and quick. The satisfying results are given in the experiment.更多还原
