室内定位方法的性能在很大程度上取决于使用它们的情况。为了在共享和受控的测试环境中公平地比较现有的室内定位方法，已经举行了关于室内定位的各种竞赛。但是，通过现有的比赛很难评估在工业场景中的实际表现。本文介绍了两个室内定位竞赛，分别为2017年仓库拣选PDR挑战赛和2018年仓库运营xDR挑战赛，用于跟踪仓库场景中的工人和车辆。在2017年PDR仓库拣货挑战赛中，我们根据实际仓库中实际拣货操作中测量的数据进行了独特的比赛。我们将车辆的航位推算称为车辆航位推算（VDR），并且术语xDR是由行人航位推算（PDR）加上VDR导出的。作为2017年PDR仓库拣选挑战赛的续篇，2018年xDR仓库运营挑战赛是全球首个通过智能手机使用VDR跟踪叉车的比赛。本文首先对现有的比赛进行了简要的总结，并通过与其他比赛的比较，阐明了我国比赛的特点。我们的竞赛具有独特的能力，通过使用实际测量数据作为测试数据并应用多方面的评估指标来评估仓库的实际性能。因此，由于来自许多国家的许多参与者，我们成功地组织了比赛。最后，总结了本次竞赛的结果。
The performance of indoor localization methods is highly dependent on the situations in which they are used. Various competitions on indoor localization have been held for fairly comparing the existing indoor localization methods in shared and controlled testing environments. However, it is difficult to evaluate the practical performance in industrial scenarios through the existing competitions. This paper introduces two indoor localization competitions, which are named the PDR Challenge in Warehouse Picking 2017 and xDR Challenge for Warehouse Operations 2018 for tracking workers and vehicles in a warehouse scenario. For the PDR Challenge in Warehouse Picking 2017, we conducted a unique competition based on the data measured during the actual picking operation in an actual warehouse. We term the dead-reckoning of a vehicle as vehicle dead-reckoning (VDR), and the term xDR is derived from pedestrian dead-reckoning (PDR) plus VDR. As a sequel competition of the PDR Challenge in Warehouse Picking 2017, the xDR Challenge for Warehouse Operations 2018 was conducted as the world's first competition that deals with tracking forklifts by VDR with smartphones. In the paper, first, we briefly summarize the existing competitions, and clarify the characteristics of our competitions by comparing them with other competitions. Our competitions have the unique capability of evaluating the practical performance in a warehouse by using the actual measured data as the test data and applying multi-faceted evaluation metrics. As a result, we successfully organize the competitions due to the many participants from many countries. As a conclusion of the paper, we summarize the findings of the competitions.
