I believe DriveWorks supports 3 camera models as of today: Pinhole, ocam and ftheta. Pinhole and ocam models and their parameters are well understood but I haven’t found much regarding the ftheta model. I understand that we can extract the ftheta parameters via Nvidia’s camera calibration procedure but I would like to understand the literature behind the model.
Would it be possible to share the documentation or references regarding the ftheta model?
Thanks in advance
