Microsensor Based 3D Inertial Measurement System for Motion Tracking in Crash Tests

摘要

Novel inertial measurement units render possible for the first time the observation of the trajectories of arbitrary and especially hidden objects in vehicle crash tests. These units employ standard micro-electro-mechanical system inertial sensors that need a non-recurring comprehensive calibration to meet precision requirements. Inertial measurement units are the complement of today's photogrammetry and permit the improvement of passive vehicle safety.
