Sorry if it’s a trivial question but I’am a beginner.
I am working on 3D reconstruction from multi-images project.
I am working with these datasets.
There is a par.txt file including the camera intrinsic and extrinsic parameters. As far as I know the extrinsic parameter contains the translation and rotation of the camera coordinate W.R.T. the world coordinate.
How can I know where the world coordinate origin is?
