Documentation on ftheta camera model


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


Dear goksan.isil,
Ftheta in NV internal model and similar to “A generic camera model and calibration method for conventional, wide-angle, and fish-eye lenses.” IEEE transactions on pattern analysis and machine intelligence 28.8 (2006): 1335-1340.

You may check it for your understanding.

THank you!
