Editor's Notes
- This presentation contain the presentation about the regular paper and survey of the exiting competitions and the announcement of Winer of our new competition xDR challenge.
- This years competition xDR challenge in warehouse operations 2018 was held as an sequent competition to the PDR challenge. In the new competition, we added dead reckoning for forklift as the tracking target. We renamed competitions name xDR challenge: xDR means PDR plus VDR (Vehicle dead-reckoning) Maybe we are going to add other types of dead-rekoning in the future Here are important date for the competition, it was very tight schedule for the competitors. In this presentation we will announce the winner of the competitions. Our sponsors are: BIGLOBE, Sugihara software & electron industry, GOV, sumitomo electric Industries, and PDR benchmark Standardization committee.
- As I mentioned, In this year, There are two competition tracks And they individually determine winner in each track. In the PDR, as the same as last year’s competition, The competitors’ PDR algorithm is suppose to track worker who move by foot during warehouse operations This is a off-site competition, We share the smartphone and warehouse data as same as last year In the VDR track, which is a new track this year, The VDR algorithm is supposed to track forklift driven by employee during the operation. The shared data are saved in same format and contends are almost same with PDR track, The smartphone data for VDR are measured by attaching smartphone onto the forklift. For the VDR beginners, we provide sample easy test data with know path. Also we plan to give some points for those who can only estimate partial element such as speed in operation or not.
- Finally, we introduced xDR Challenge parts The scenario of the xDR Challenge is warehouse work, It become more general including tracking the forklift. The added the scale of the data measument, We measured the warehouse work for 5 Full-business days. Total 34 people, 6 forklift equals 170 (PDR data ) and 30 VDR data. About 8 hours / data.
- Here are Prizes (読まない) We awarded winner and runner-up for each tracks. The winners can cases and extra prize shown in the figure.
- One extra prize is VDR module. As you can see, winner can get the devices which can track the forklift.
- As we documented in the regulation documents, This year, we adopt rigorous evaluation of error accumulation. Last year, we only evaluation the submitted result which potentially include effort with PDR, BLE-beacon, WMS, and MAP Map matching. It is hard to extract the effect purely from the PDR. This year, we Intentionally delete partial BLE signal logs from the test data for evaluating PDR accumulated error. We call these period the BLE signal are deleted as BLE unreachable period: BUP in short. With BUP, we evaluation absolute median error of integrated localization only outsize of BUP. And we evaluate the PDR accumulating error in BUP
- Finally I’m going to announce the result of this years xDR Challenge.
- The xDR Challenge is successfully gather the participants from three contrites # number of pre-admission was 7. 5 teams registered final registration for PDR track, And 2 teams registers in VDR track Unfortunately 1 team for registered both tracks withdrew at the last moment.
- Here is a list of the sensor data provided for the competitors. Despite, We measured much more data in the measuring we selected the data. The amount data is still big. The competitors submit 16 trajectories for PDR track (130 hours) And 8 (60 hours) trajectories for VDR track. We think this huge amount of data works for avoiding fine-tuning.
- OK, here is a final result I guess the what makes a difference between winner and runner-up is that High level balance of error related metric and other metrics. In other words, 1th ranked team and 2nd ranked team almost get similar score for Emedian_error nad E_accumu_error The perfectness of the other mtrics makes the difference. I think this is very good result for evaluating metric designer, because many metrics are contribute The final results.
