Calibration of an Inertial Measurement Unit for Improving the Accuracy of a Biomechanical Skeleton

摘要

A calibration fixture provides a repeatably accurate tool for measuring offset angles between measurement axes for inertial measurement units (IMUs) used in motion capture. The measured offset angles may be used to correct angles measured by the IMUs to create a biomechanical skeleton that accurately represents movements of a motion capture subject. The disclosed embodiments are applied segments of a biomechanical skeleton providing a mathematical model of a human arm and hand.
