2021 July - 10 articles

Cover Story: Inertial measurement units (IMUs) enable orientation, velocity, and position estimation in many application domains. Errors in orientation estimation greatly affect any of those motion parameters. We propose an extensive benchmark dataset that includes 3D inertial and magnetic data with synchronized optical-marker-based ground truth measurements: the Berlin Robust Orientation Estimation Assessment Dataset (BROAD). Furthermore, we introduce well-defined benchmark metrics and perform an exemplary case study on widely used, openly available IOE algorithms. Due to the broad range of motion and disturbance scenarios, the proposed benchmark is expected to provide valuable insight and useful tools for the assessment, selection, and further development of inertial sensor fusion methods and IMU-based application systems.
