我正在使用基蒂立体数据集(http://www.cvlibs.net/datasets/kitti/eval_stereo.php),我想计算基准矩阵,但未在校准文件中给出。然而,对于一对立体图像,给出以下信息:如何计算Kitti数据集的基本矩阵?

S_xx: 1x2 size of image xx before rectification 
K_xx: 3x3 calibration matrix of camera xx before rectification 
D_xx: 1x5 distortion vector of camera xx before rectification 
R_xx: 3x3 rotation matrix of camera xx (extrinsic) 
T_xx: 3x1 translation vector of camera xx (extrinsic) 
S_rect_xx: 1x2 size of image xx after rectification 
R_rect_xx: 3x3 rectifying rotation to make image planes co-planar 
P_rect_xx: 3x4 projection matrix after rectification 

如何从这些计算基本矩阵?
