Hi, I have two questions.
**First question.**
I have marker. I get 2D coords of marker in pixels (image plane).
I can get rotation and translation matrix that looks like:
| r00 r01 r02 t0 |
| r10 r11 r12 t1 |
| r20 r21 r22 t2 |
| 0 0 0 1 |
Am I wrong or t0, t1 and t2 represents position of marker (x, y, z) in camera coordinate system? **Second question** Can I use cvFindExtrinsicParameters2 to calculate 3D coords if I have 2D coords in pixels, intrinsic and extrinsic parameters? Or it is used only to calculate rotation matrix and translation vector?
