基于代数约束的图像生成方法研究

Algebraic Constraint-based View Rendering

介绍一种利用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。该方法通过研究物体在个不3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、对应点之间的代数关系,进而得到新的视角图像。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,且实现方法简单快捷。实验效果令人较满意。

A new technique for the image rendering based on algebraic constraint is proposed. It is used to render novel view from two reference image of different location. By studying the geometry relationship among the corresponding points on three different projective planes, the tri-linear tensor constraining the corresponding points of different view is obtained. From this tensor the corresponding relationship between 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.
