• Abstract summary: The technique implements an augmented reality (AR) based positioning system that is used to annotate the wireless signal parameter data samples. We track the position of a practical and low cost navigable setup of cameras and a Bluetooth Low Energy (BLE) beacon in an area decorated with AR markers. Our results show that we can reduce the positional error of the AR localization system to a rate under 0.05 meters.

• Abstract: We introduce a novel technique and an associated high resolution dataset that aims to precisely evaluate wireless signal based indoor positioning algorithms. The technique implements an augmented reality (AR) based positioning system that is used to annotate the wireless signal parameter data samples with high precision position data. We track the position of a practical and low cost navigable setup of cameras and a Bluetooth Low Energy (BLE) beacon in an area decorated with AR markers. We maximize the performance of the AR-based localization by using a redundant number of markers. Video streams captured by the cameras are subjected to a series of marker recognition, subset selection and filtering operations to yield highly precise pose estimations. Our results show that we can reduce the positional error of the AR localization system to a rate under 0.05 meters. The position data are then used to annotate the BLE data that are captured simultaneously by the sensors stationed in the environment, hence, constructing a wireless signal data set with the ground truth, which allows a wireless signal based localization system to be evaluated accurately.

  Fingerprint-based localization improves positioning performance in challenging, non-line-of-sight (NLoS) dominated indoor environments. Channel-charting avoids this labeling effort as it implicitly associates relative coordinates to the recorded radio signals. We propose a novel framework that does not require reference positions to keep the models up to date.
