how to calculate the inliers points from my rotation and translation matrix?

how to calculate the inliers points from my rotation and translation matrix? if I have the points lists std::vector<point3d> opoints; std::vector<point2d> ipoints; and I have the rotation and translation matrix, How can I calculate the inliers points

I know that cv::solvePnPRansac will calculate the inliers, rotation and translation from the two points list, but I need to calculate the inliers from my rotation and translation?

Thanks for your support

You can't know absolutely, but you can set an error threshold. Then any points that have less than that error are inliers.

Use projectPoints on the 3d to get a set of 2d points. Then calculate the error of the projected points from the "true" points as sqrt(diffx^2 + diffy^2).
