To avoid the degenerate configuration when directly computing the homography given the epipolar geometry in curve scene,the area-detection approach is presented in this paper.
为了提高立体图像匹配精度和速度,提出了一种改进的场景无关约束下的特征匹配算法,该算法针对用对极约束和同形映射来进行曲面场景匹配的过程中同形估计容易出现降阶的情况,通过引入区域面积检测法来避免降阶情况的发生,以改善匹配结果;同时,由于在同形矩阵估计中,通过加入基础矩阵和同形矩阵本质上的约束关系,可使得原本独立的同形约束和对极约束关系很好地融入到匹配的整个过程中,从而快速有效地抑制了错误匹配的发生。

平面型场景图像的三维度量重建就是确定图像平面到度量平面的八自由度同形矩阵,通过对平面型场景图像的三维度量重建方法的阐释,提出了非层次化平面型场景图像的三维度量重建方法,该方法不必对摄像机定标,直接考虑射影图像平面上的圆点Ip和Jp,Ip和Jp包含非度量矩阵N的四个自由度,把它们结合起来用两个圆点Ip和Jp表示对偶二次曲线来计算非度量矩阵N,基于场景几何知识,计算图像平面和世界平面之间的非度量矩阵N后就可得到平面型场景图像的三维度量重建。
