Aircraft State Estimation using Inertial Sensor and Stereo Camera Pair
State determination is essential for a small unmanned air vehicle (UAV) to achieve fully autonomous control and navigation. For that purpose a new method for estimating aircraft state is presented using a MEMSbased Inertial Measurement Unit (MIMU) combined with a stereo camera pair. This approach is realized by a Kalman filter and an Extended State Observer (ESO). By fusion of measurements obtained from MIMU and vision data from ground feature tracking, the velocity and horizontal attitude of the aircraft are estimated. Furthermore, the algorithm must be robust with respect to noise in the measured feature point positions in the image plane. Simulation is presented for a small UAV flight through a virtual environment. And its results show good performance and robustness.
