i know calib_cam_to_cam.txt in kitti. So i can use
""" 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 """
this information.
but i can't make Px in calib.txt using this information. (R_rect * K_xx * [R_xx|T_xx]) how do i get Px matrix?
