OpenCV's projectPoints function

Question

I\'m currently trying to implement a example of OpenCV\'s projectPoints method. The idea behind this method is taking as input a set of 3D points, translation/rotation vecto

Answer 1

It seems to be complaining about the type of the output vector of points. Try to replace your call to projectPoints:

cv::projectPoints(objectPoints, rVec, tVec, intrisicMat, distCoeffs, projectedPoints);

by this call:

cv::projectPoints(objectPoints, rVec, tVec, intrisicMat, distCoeffs, imagePoints);

This uses the variable of type std::vector<cv::Point2d> instead of std::vector<cv::Point2f>.
