Thanks for your questions. We'll double check your questions here and soon give you the reply.
An update for this issue.
About Q1. I thought the purpose of the eq5 is to convert pixel coordinates to normalized coordinate(z=1) as other distortion model does, but what you actually intended was to make pixel coordinates range from -1 to 1 right? And if p' is distorted pixel coordinates, then the ray direction in eq 8 is a distorted ray direction? I expected p' to be undistorted pixel coordinates so it's a bit confusing.
About Q2,3,4 Thank you for your confirmation. You cleared things up.
Q1 Is it true that each element of n is divided by c ? not f?
Also, what is the meaning of p' value? undistorted pixel?
Q2 In this equation, I'm not sure why $z_d$ is multiplied twice.
Q3 In this equation, why divide it by $r{A,d} \cdot r{A,d}$ instead of $||r_{A,d}||$ ?
Q4 In this equation, round L in the last term should be round r?
