Abstract

Head attitude tracking system based on MIMU can only maintain a short-term higher accuracy in the process of measurement. In order to overcome the defect, a new method by using CCD is proposed in this article. It introduces a CCD sensor to detect real-time head attitude, and then, delivers the posture to MIMU to accomplish the calibration process. For CCD could output a high precision data in a small field of view, the drift caused by gyroscopes and accelerometers in MIMU can be corrected effectively. Through the system authentication, we find that the method decreases the drift caused by MIMU obviously and keeps a high precision of measurement.
