I am doing a view plane localization research. First I need to annotate the plane as the ground-truth. I use the “Markups” module of 3D Slicer to annotate the plane. But after i annotated the plane and export the json file. I used the “baseToNode” as the rotation matrix to extract the annotated plane, but i can not get the annotated plane. How can i get the annotated plane using python? Should I using the key “center” and “normal” in the json file?
This is my annotate plane!
