# - 18th October 2020
# - Copyright Mark Caldwell 2006
# - Tested with Vue R5 (2020)
#
# How to use in 4 easy steps
#
# 1. Download this file onto your computer
#
# 2. Change Path to Saved File
#
# 3. Then run script and wait for it to work
# To run it go to Python -> Run Python Script
# Then locate the file on your computer
#
# 4. Camera path and rotation are now stored in the CSV
# File and can be loaded using loadcameradata.csv
