* Possible approachSee above. Further notes:A. # Backpack points can be transferred to coordinate system of VICON using output of tracker (6DOF pose transformation between VICON and Backpack coordinate system). Tracker has better optimization techniques than nexus therefore trajectories are more complete. The result is compared with 3D points given by Nexus and a combined dataset can be created. B. # Results from A is step 1 can be compared with .csv of unlabeled points (Tracker output of 3D all detections) to label all detected 3D points and remove ghost points.C. # The combined result from A 1 and B 1 can be used then to identify random flips in angles, positions and IDs.
