Segment Statistics module solves this very nicely: it can compute oriented bounding box and principal axes directions for each segment, directly from the segmentation.

To enable them, click on the “Options” button beside the “Labelmap Statistics” checkbox, and select the statistics that you would like calculated from the popup window. You can read the documentation for the Segment Statistics module [here](https://slicer.readthedocs.io/en/latest/user_guide/module_segmentstatistics.html). Oriented bounding box:
