Call For Competition


IPIN is pleased to announce the eight IPIN 2021 Indoor Localization Competition. The competition is aimed at bringing together the academic and industrial research communities for evaluating different approaches and envisioning new research opportunities for the indoor localization area, where no generally accepted standards exist yet.

The competition builds  on the experience of previous competitions  and is based on  the  EvAAL  framework,  ensuring experience,  solidity  and  a  well-founded scientific  method.   IPIN  2021  Indoor Localization  Competition  is  entirely off-site.  It hosts three different Tracks:

  • Track 3: Smartphone (off-site)
  • Track 4: Foot-mounted IMU (off-site)
  • Track 7: Channel impulse response (off-site)
Competitors calibrate their algorithms in advance using a ground truth reference database, and compete using new unreferenced data.

Track 3 - Smartphone: A pedestrian walking under realistic conditions in multi-floor buildings using data provided by a conventional smartphone.

Track 4 - Foot-mounted IMU: A pedestrian carries ULISS (Ubiquituous Localization with Inertial Sensors and Satellites), a state-of-the-art Inertial Navigation System producing IMU data, MAG data, PRESSURE data & GNSS data, without the help of any maps.

Track 7 - Channel impulse response: People with UWB tags move through a cluttered industrial indoor environment in LOS and NLOS conditions.

The evaluation criteria for the competition, restrictions on the accepted technologies, technical rules and a description of the benchmarks are detailed in the technical annexes to this call. Possible refinements of the annexes, even based on applicants' comments, will be timely distributed on the competition This e-mail address is being protected from spambots. You need JavaScript enabled to view it and will appear on the EvAAL web site.

Competitors in Tracks 3 and 4 obtain sensor readings and submit position estimates through the EvaalAPI web service. The purpose is to emulate a causal process similar to the data flow of an on-site competition: input data can be read only once and only in sequence, and the timestamp of each submitted position estimate must be the same of the latest sensor reading.

All the data gathered by the competition committee during the competition, including data produced by competing systems, are published after the competition for the purpose of research and comparison. Winners of the competition are announced on the EvAAL and IPIN web sites and on the contest mailing list. Scientific publishing opportunities will be offered to competitors.

A competitor can be any individual or group of individuals working as a single team, associated to a single or a number of organizations, who applies to participate in one or several Tracks. Only one team from the same organisation (laboratory) is allowed to compete in any number of Tracks. Registration to the competition is included in the registration of at least one team member for the IPIN 2021 conference, and counts as a single paper or poster published at the conference. Alternatively, registration to the competition costs 100€ for the first Track plus 50€ for any additional Track, to be paid when results are submitted, see the IPIN 2021 web site. Competitors must contact the chair of the relevant Track to get information, communicate their registration and provide the final results.

News and updated are being posted to the contest mailing list (subscribe here).
