My Question
Hello everyone,
First of all, thank you for your contributions to this great library!
This question might or might not turn into a minor bug. I was reading the code for EvaluateRANSACBasedOnDistance and I found the following formula:
result.inlier_rmse_ = error / std::sqrt((double)inlier_num);
However, error is collected by adding absolute values (as opposed to squared):
double distance = std::abs(plane_model.dot(point));
...
error += distance;
Given how the error is accumulated I was expecting to find a mean absolute error. Is there any reason for the denominator to be the square root of the sample size rather than just the sample size? I might be missing something (or maybe it is indeed a minor bug) so any ideas are welcome.
Thank you for your time :)
