Calibration Training interface (Find the radial distortion value)

[chulminy]

Hi all

I'm using the calibration training interface in Vision NI. I completed all the step but I couldn't check the values of radial distortion. I want to compare all camera and lens internal parameters with those from other software. However, I don't know where I get those vales from. 

Could somebody let me know? 

Thanks

chulminy, 

What steps have you gone through so far in the Calibration Training Interface? Which calibration type are you using?

[chulminy]

I finished all process in calibration trainning interface. But, I could not find k1, k2, k3 values in my final results. The calibration type is "distortion model (Grid)". 

I want to know how can I check the k1, k2, k3 values. 

Thanks

I don't believe you can extract these coefficients using the Calibration Training Interface. CTI has little customizability so when you want to change something or extract data from the system there is little opportunity to do so. I found a LabVIEW example that helps do this for you, "Calibration Models Comparison.vi". It can be found in the NI Example Finder in the path Toolkits and Modules>>Vision>>Functions>>Calibration Models Comparison.vi.
I hope this helps.

Thank you very much. It really helps.
