The ROI frame
The ROI frame is a coordinate system used throughout the Pickit experience:
Setup: The ROI frame is created when building the Region of Interest (ROI) box. The ROI box is positioned with respect to it.
Detection: Detected object positions displayed in the web interface can be reported with respect to the ROI frame (and also with respect to the robot base).
Picking: The preferred pick orientation is typically specified with respect to the ROI frame.
The ROI frame is represented using dashed axes, as shown in the image below, where it appears centered in the ROI bottom.
