How to know the threshold param?

[michaeleggers]

Hi.

Nice program. I got it to work but how can one know the threshold param? Got it to work by trial and error only...

hi! thank you for your question. the most simple technique is indeed using only trial and error. however, you could experiment with statistical analysis of the residuals (standard deviation for example). or try adaptive thesholding where you try to maximize the number of inliers while paying attention to the value of residuals. this is more complex but depending on your task, it might be worth it

Thank you for the explanation. Burried somewhere in literature I also found the trial and error method, it is even described as a viable method. The standard deviation was not known to us so we went with tria and error ;) It worked well enough. Cheers!
