computeReprojectionErrors

[WYoseanLove]

Regarding the computeReprojection error:

current code is as below :

err = cv::norm(cv::Mat(imagePoints[i]), cv::Mat(imagePoints2), cv::NormTypes::NORM_L2);

is it need to be divide by the objectPoints size?

err = cv::norm(cv::Mat(imagePoints[i]), cv::Mat(imagePoints2), cv::NormTypes::NORM_L2)/ objectPoints[i].size();

Hi,

this code base is fairly outdated and at the time it was mostly just a compilation of various clippings from the opencv docs.
I would recommend looking there for updated code as I'm node sure what the correct way fo doing things is now.

This is where I got it from eventually but again may be outdated.
