我正在使用基蒂立體數據集(http://www.cvlibs.net/datasets/kitti/eval_stereo.php),我想計算基準矩陣,但未在校準文件中給出。然而,對於一對立體圖像,給出以下信息:如何計算Kitti數據集的基本矩陣?
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
如何從這些計算基本矩陣?
