I want to send the marker center coordinates to MarkerTracking using the marker angular coordinates obtained with LiveSketchScript.
At present, you can refer to each variable itself, but you cannot know how to handle point2f and you cannot assign a numerical value.

LiveSketchScript side

mt.WStartp = corners;

I want to put the center coordinates in the

part and put it in WStartp.

If i run this way

OpenCvSharp.Point2f [] []
UnityEngine.Debug: Log (Object)
MarkerTracking: Update () (at Assets/MarkerTracking.cs: 26)

It just comes out on the console and doesn't contain any numbers.
How can I get and calculate the contents of point2f?

Thank you.
