Evaluation of low-cost/high-accuracy indoor positioning systems

Indoor positioning is a challenging research topic. Over the years, many different measurement principles and algorithms have been proposed. Each system has its own advantages and drawbacks, therefore trade-offs have to be made. For example, one generally needs to make a trade-off between cost and accuracy. However, recent developments in sensing technology have led to commercial systems that advertise sub-decimeter positioning accuracy for less than €1k. In this paper, we benchmark the accuracy of indoor positioning systems by Pozyx labs and Marvelmind robotics, as well as the VIVE tracker by HTC and Aruco Marker tracking in OpenCV. Results show that these systems achieve an average dynamic positioning accuracy of approximately 150 mm, 20 mm, 8 mm and 100 mm, respectively.status: publishe
