Hello,
I've been experimenting with camera calibration parameters and have processed a model with two different configurations. The configurations are as follows:
1 - F, Cx, Cy, B1, B2, K1, K2, K3, K4, P1, P2
2 - F, Cx, Cy, B1, B2, K1, K2, K3, K4, P1, P2, P3, P4
These two configurations give quite different distortion plot results and I am trying to understand the meaning of them (see image attached). The first distortion plot seems quite realistic, increasing distortion with increasing radius. The second distortion plots looks odd, but gives better RMSE on check points, and there is lower distortion in the decentering plot. Is the second plot realistic? Or is it a case of over parameterization? Any advice you have is appreciated.
