How to get Skeleton Joints Coordinate to local file?

Hello guys,

I am trying to make datasets for pose estimations automatically.
They needs three kinds of data - segmentation area, bounding box, and skeleton keypoints.
I could get segmentation areas and bounding box coordinates to use plugin “UnrealCV”.
But I couldn’t get joint coordinates of skeletal mesh, for example head, neck, shoulder, wrist, and so on.



Does anybody have an idea?
