Review of PDR Challenge in Warehouse Picking and Advancing to xDR Challenge

摘要

In this paper, we present a review of the competition track organized by us at IPIN 2017. Our competition track was named as “PDR challenge in warehouse picking”. Our pedestrian dead-reckoning (PDR) challenge focused on testing the PDR methods under a realistic scenario, which is tracking employees during the picking operation in a warehouse. Firstly, we introduce an overview of the PDR challenge including detailed information of all evaluation metrics. Secondly, we summarize the results and findings from the competition and list the challenges that should be tackled in the next competition. Thirdly, we introduce the design concept of an xDR challenge by reflecting the findings and feedback of design of the competition. The target of the PDR challenge was only the employees who move by foot during working in the warehouse. The main update in the xDR challenge is dealing with forklifts driven by employees as well as walking employees. We term dead-reckoning of a vehicle as vehicle dead-reckoning (VDR). The term xDR is derived from PDR plus VDR. Another update is providing reference data for the reconstructing situation of picking operation in the warehouse by using an IMU-based motion capture system.
