Camera calibration / coordinate system

Hello,

I want to calibrate the camera. Now I have to enter position and quaternions. Where is the reference point of the coordinate system for the position? And do I only need the quaternion information for rotation of the camera?

Thanks

Dear BjoernFathIPG,

Camera calibration material and docs in /usr/local/driveworks-0.3/doc/nvdwx_html/dwx_calibraion_tools.html and /usr/local/driveworks-0.3/doc/nvdwx_html/NVIDIA_DriveWorks_Calibraion_Tool.pdf in DrivePX2.
Could you please help to check it? Thanks.
