摘　　要：介绍一种新的由两幅不同角度的参考图像生成另一幅新的视角图像的图像生成方法 .该方法在极线几何的基础上 ,通过研究物体在 3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 .A new technique for image rendering based on two reference images of different location to ren- dera novel image was proposed.By studying the geometry relationship among the corresponding points on three different projective planes based on epipolar geometry,it obtained the trilinear tensor constraining corresponding points of different view.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 was thus obtained.Compared with other image re- projection methods,this method needs only two reference images and is easy and quick to be implemented.The satisfying results were given in the ex- periment.
