摘要

In the present study, implementation and study of aircraft altitude estimation using un-calibrated onboard camera is obtained. A camera model has been implemented to simulate the test data. From the results, it was observed that the rounding nature of pixel coordinates creates fluctuations around the true vanishing point (VP) angle and height computations. These fluctuations were smoothened using a Kalman filter based state estimator. The effects of camera tilt and focal length on VP angle and height computations were also studied. It is concluded that the camera should be perpendicular to the runway for there to be no effect of the focal length on the height computation. It is being planned to apply this algorithm for real time imaging data along with Integrated Enhanced Synthetic Vision (IESVS) on HANSA aircraft.
