xDR (PDR & VDR) Challenge for Warehouse Operations 2018

  1. 1. xDR Challenge for Warehouse Operations 2018 ISO IEC/JTC 1/SC 24 (2018/8/6)
  2. 2. Indoor Positioning Technologies 22
  3. 3. 23 • Was held as the official competition track (Track 4) of IPIN (Int. Conf. on Indoor Positioning & Indoor Navigation) in Sapporo, Japan 2017 • IPIN 2017 competitions: total 4 tracks, 20 teams joined (CN5, KR4, JP3, TW2, GE2, AU1, FR1, CL1, PT) • Track4: Off-site PDR competition for workers’ positioning during picking operations in an actual warehouse PDR Challenge in Warehouse Picking
  4. 4. 24 Indices related to accuracy Ed – Index related to integrated positioning error Es – Index related to PDR error based on EAG Indices related to the trajectory naturalness Ev – Index related to the naturalness of travel speed Ef – Index related to position measurement output frequency Specific indices for warehouse picking scenario Eo – Index related to collision with obstacles Ep – Index related to motions during picking work Evaluation Indices & Indicators Proposed indicator: EAG (Error Accumulation Gradient) Positioning error per unit time based on discussion in Abe, M., Kaji, K., Hiroi, K., Kawaguchi, N. PIEM: Path Independent Evaluation Metric for Relative Localization, in Proceedings of the Seventh International Conference on Indoor Positioning and Indoor Navigation, IPIN2016. eCDF: Empirical Cumulative Distribution Function
  5. 5. xDR Challenge for Warehouse Operations • Competition of Dead-Reckoning for Pedestrian and Vehicle – xDR=PDR+VDR • Important dates – Testing period begins: Mid May, – Testing period ends: Mid August – Results submission: 7th September – Announcement of Winners: During SS in IPIN2018 • Host – PDR Benchmarking Standardization Committee 25
  6. 6. Vibration-based Vehicle Dead Reckoning (movie provided by Sugihara SEI) 26
  7. 7. What’s New • Adding forklifts as tracking targets – Smartphones are attached onto forklift during the operation • Expanding scale of the measurements 7 people (PDR)× 3 hours(2017) ⇒34 people(PDR)+6 forklifts (VDR)× 8 hours × 5 days(2018) 27 • Providing reference motion of warehouse operations measured on site • 1 worker for 2 hours • Whole posture motion: Commercial IMU-based motion capture system (Xsens’s Awinda) • 3D structure of warehouse: Reconstructed by Structure-from- Motion with 360 deg. 4K panoramic movie (by Ricoh's THETA V & Context Capture)
