Camera models for calibration tool DriveWorks 1.2

When running ./calibration-intrinsic-constraints in the calibration tool box on Drive PX2, apart from ocam which are other values that can be used in --camera-model (i.e pinhole, ftheta)? or is only ocam supported? If I have Sekonix ar0231-rccb-bae-sf3325, which is 60 deg FOV, what should I use? With earlier calibration tool I was using pinhole model.

Thank you

Dear cad297,
I don’t find any --camera-model parameter to calibration-intrinsic-constraints tool in documentation(DRIVE_Software_Docs\DRIVE_Software\dav\dwx_intrinsics_constraints.html). Can you please point me to your reference?

I cant find information in the documentation, but when I run the tool there are parameters listed. See copy paste from terminal below

Dear cad297,
We recommend using Ftheta model. Let us know if you have any issues with that.

Is there any documentation or references on how parameters for ftheta model are used for rectification or distortion?


We don’t have a document for it currently.

It is polynomial model.
We approximate the radial distortion with second order polynomial.
