Dataset: camera parameters

[sararojas]

I was wondering how you extracted the dataset for GSN since I'm trying to do the same with another dataset. However, I don't manage to do it. I see that Habitat AI uses quaternion, how did you switch to rotation-translation and intrinsic matrices?

Could you please help me? Could I access the code you used for this?

thanks and much appreciated :)

Hi @sararojas,

We use VizDoom [http://vizdoom.cs.put.edu.pl] and habitat-sim [https://github.com/facebookresearch/habitat-sim] to extract camera extrinsic and intrinsics for the different datasets we released. Habitat-sim is a great simulator with a lot of documentation and capability to work with a bunch of already existing datasets. My recommendation would be to use it whenever you can.
