The documentation does not provide any details for the ftheta camera model.
This post states that it is actually the Kannala-Brandt generic camera model. The Kannala-Brandt model specifies the forward projection parameters in a form: [
k1, k2, fu, fv, u0, v0, ....]
dwFThetaCameraConfig structure specifies the back projection polynomial:
backwardsPoly and the center of projection (
