无穷远平面 meaning in Chinese
plane at infinity
Examples
- We analyze the essence of affine reconstruction and prove the sufficient conditions that a reversible matrix can be an infinite plane homography matrix and we can not uniquely decide an infinite plane homography matrix from fundamental matrix
详细分析了仿射重构的本质，证明了可逆矩阵为无穷远平面单应矩阵的充分条件，以及从基本矩阵无法唯一确定无穷远平面单应矩阵。 - Expatiate the substance of projective reconstruction is solving fundamental matrix , substance of affine reconstruction is solving infinite homography or infinite plane and substance of metric reconstruction is solving absolute conic images
阐述了射影重构的实质是求解基本矩阵，仿射重构的实质是求解无穷远平面或无穷远平面单应，欧氏重构的实质是求解绝对二次曲线的像。 - This one - constraint - less property of the kruppa equations is their inherent deficiency and is independent of camera motion . this deficiency is due to their failure of automatic enforcement of the rank - three - ness on the absolute quadric
从而, kruppa方程的独立个数比基于绝对二次曲面或基于无穷远平面的自标定方程的独立个数少1 ,这是源于kruppa方程不能保证绝对二次曲面的秩为3 ,是由kruppa方程自身的特性决定的，而与摄像机的运动无关。 - In the first part , depending on three or more images , the main research work are listed as follows : ( l ) using svd decomposition to realize projective reconstruction ; ( 2 ) realizing camera self - calibration by solving kruppa ' s equation ; ( s ) recovering euclidean reconstruction from projective reconstruction . depending on only two images , the main researches are : ( l ) making out infinite plane homography matrix by using scene structure information , then recovering affine reconstruction from projective reconstruction ; ( 2 ) making out the absolute conic images by using scene structure information , and then recovering euclidean reconstruction from projective reconstruction
在第一部分中，针对三幅及三幅以上的图像，主要研究：利用矩阵奇异值分解( svd )实现射影重构，通过求解kruppa方程实现摄像机自标定，由射影重构恢复欧氏重构；针对只有两幅图像的情况，主要研究：利用场景结构信息求解无穷远平面的单应矩阵，由射影重构恢复仿射重构，利用场景结构信息求解绝对二次曲线的像(等价于标定摄像机) ，由仿射重构恢复欧氏重构。 - In 3d space , points on the infinite plane compose the absolute conic , and it contains the interior parameter information of camera . we use photography geometry character of circular point on the absolute conic to calculate camera interior parameter , exterior parameter can be obtained . we can obtain more accurate
在三维摄影空间中,无穷远平面上的点构成了绝对二次曲线,由于二次曲线的像包含了摄像机的内部参数信息,我们利用了圆环点的像在二次曲线上的摄影几何特性,从而确定摄像机的内部参数,进而求取摄像机运动的外部参数。
