Dataset used for manuscript: Drift-Free 3D Orientation and Displacement (DFOD) estimation for quasi-cyclical movements using one inertial measurement unit: Application to running

This dataset contains simultaneously measured data of an inertial measurement unit (IMU) on the lower leg and an optical motion cluster marker set on the same lower leg. Goal of the measurements was to develop a new algorithm to estimate Drift-Free 3D Orientation and Displacement (DFOD) using the quasi-cyclical nature of lower leg movements during running. This study was conducted according to the guidelines of the Declaration of Helsinki, and approved by the Ethics Committee of METC Twente.
