Camera Calibration Part 2 Issue Still Not Fixed

[swinterbotix]

This was already mentioned in Issue #70, but the second part of the camera calibration procedure still fails using the Python 3 installation (even on the most recent commit to master). The specific part is below...

Also note that when running the second half of the camera calibration procedure, I get an error originating from line 66 in the solve_for_calibration_params.py script saying 'UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte.' I was able to fix this issue by editing that line to read...

tt = pickle.load(open(os.path.join(dir_name, "states.pkl"), 'rb'))

I believe the above issue has to do with the pickle.load function operating slightly different between Python 3 and lower versions. But I know that the above code fixes the issue when working in Python 3.

Note that I also tested this using the Python 2 installation, and it worked just fine there.

Thanks
