solvePnPRansac, getting inliers from the 2d and 3d points?

edit

I am running solvePnPRansac, and after it runs, i need to get the inlier points from the input matrices. The inlier Mat seems to be a list of ints, rather than the 0 or 1 values that i would expect. What is the best way to run this:

    cv::Mat points3D_t0; // Mat of 3d points
    std::vector<Point2f> points_left_t1; // vector of 2d features

cv::solvePnPRansac(points3D_t0, points_left_t1, intrinsic_matrix, distCoeffs, rvec, tvec,
    useExtrinsicGuess, iterationsCount, reprojectionError, confidence,
    inliers, flags);

and then fill a std::vector<Point2f> and a std::vector<Point3f> with the matched inlier points that were used in the PnP solve?

Thank you.
