estimateRigidTransform missing from 3.5+

I have moved from 3.4 to 4.0 and cv2 is missing the estimateRigidTransform function. The documentation shows it is still there in the C++ library but it is not in cv2. Has it been renamed or am I missing something stupid when im building it?

I checked 3.5 and it looks like it is the first version where it is missing.

You can use the estimateAffine3D as follows:

cv::Mat get_rigid_transform(std::vector<cv::points3d> poinst1 , std::vector<cv::points3d> points2)
{

   cv::Mat affine_transformation = cv::Mat::eye(3, 4, CV_64F);
   std::vector<uchar> inliers;
   cv::estimateAffine3D(points1, poinst2, affine_transformation, inliers);
   return affine_transformation;
}

As you can see in the doc, estimateRigidTransform is now deprecated.

You should use estimateAffine2D or estimateAffinePartial2D

Also, I'm pretty sure that OpenCV 3.5 does not exists: you go from 3.4.4 to 4.0.0.
