Can you give me stereo pairs dataset with camera calibration information? That has Q matrix that I need for OpenCV reprojectImageTo3D function or has such information that I can construct Q matrix. Or at least dataset with focal length in mm and baseline info, that I can write custom reprojection.

  • @DaveDurbin: Where is it duplicate? Middlebury datasets don't have Q matrix, and I know about it. – Aram Gevorgyan May 12 '15 at 08:26
  • From OpenCV docs `The matrix Q can be an arbitrary 4 × 4 matrix (for example, the one computed by stereoRectify()).` i.e. There's no particular Q matrix. If you want to construct one, you can use `stereoRectify()` which requires intrinsic and extrinsic camera parameters which are available with the Middleburg dataset I believe – Dave Durbin May 12 '15 at 11:58
  • I know about that, but middleberry datasets doesn't have enough info for stereoRectify, it has no neither Rotation and Translation matrix nor disortion coefficients. I do custom reprojection using this dataset. But it is not my question answer – Aram Gevorgyan May 12 '15 at 15:10
  • From http://vision.middlebury.edu/mview/data/. name_par.txt: camera parameters. There is one line for each image. The format for each line is: "imgname.png k11 k12 k13 k21 k22 k23 k31 k32 k33 r11 r12 r13 r21 r22 r23 r31 r32 r33 t1 t2 t3". The projection matrix for – Dave Durbin May 12 '15 at 22:40
