implement some algorithms of 6d pose estimation. note: LCHF is too hard to tune params so I'm not going to implement it... a better choice: patch_linemod.

QUESTION
I have done some 6D Pose estimation, and have the Oriented Bounding Box (OBB) of the detected object. So, now I would like to know the ground truth and get the error of the estimated orientation and the position. The detected object is a rectangular box as shown in the image.
How can I know the distance and the rotation of a marker (black box over the red one) to the camera? The red box in the image is the object and the black one is the estimated 6DPose.
So would like to do image postprocessing to get the error of the position and the orientation. So, how can get the error from this image, knowing the real dimensions of the box, camera parameters, and the distance from the camera to the object? So the triangulation formula can give me the distance but then how to get the orientation?
Would be OpenCV to look after? Any help?
Thanks

Install 6DPose
You can use 6DPose like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
