Camera Pose from Checkerboard Pose

I am using the code given by the OpenCV to find tvecs and rvecs of the camera which I calibrated intrinsically. I do get these two vectors, no problem.

rvecs: [[-0.73059634]
 [-0.02493155]
 [ 0.1556929 ]]
tvecs: [[-2.8194188 ]
 [ 1.25920043]
 [77.38695895]]

However, I am not sure if these are the values for my camera or my checkerboard. The language used in the tutorial isn't totally clear. But I think these are the values for the checkerboard, like, this isn't the pose of the camera, but rather the pose of the board, which is not why people use this code in the first place.

My question is, how could we go to camera extrinsics from these vectors?

rvecs: [[-0.73059634]

tvecs: [[-2.8194188 ]
 [ 1.25920043]
 [77.38695895]]

However, I am not sure if these are the values for my camera or my checkerboard. The language used in the tutorial isn't totally clear. But I think these are the values for the checkerboard, like, this isn't the pose of the camera, but rather the pose of the board, which is not why people use this code in the first place.

Also, if these are actually the camera parameters, then one must multiply 77 with the size of one checker that he uses. Mine has 11 mm side, so for me the height would correspond to 77 * 1.1, which is also wrong since I measured the height and it's not that high.

Sometimes is fishy here.
