Why is my code snippet giving my weird results for projected points?

vector<Point3d> points_3d;

points1_3d.push_back(Point3d(10, 10, 100));
Mat points3d = Mat(points_3d);


Mat rvec = (Mat_<double>(3, 3) << (1, 0, 0, 0, 1, 0, 0, 0, 1));

Mat tvec = (Mat_<double>(3, 1) << (0, 0, 0));

Mat K = (Mat_<double>(3,3) 
    << (1000, 0, 50,
        0, 1000, 50,
        0, 0, 1));


Mat points_2d;

projectPoints(points_3d, rvec, tvec, K, Mat(), points_2d);


cout << points_2d;

I get as projected 2D Point = -1.708699427820658e+024, -9.673395654445999e-026

If i calculate it on a paper on my own, i'm expecting a point P = (150, 150) with that formula:
