Optical Navigation Sensor for Runway Relative Positioning of Aircraft during Final Approach

Precise navigation is often performed by sensor fusion of different sensors. Among these sensors, optical sensors use image features to obtain the position and attitude camera. Runway relative during final approach a special case where robust continuous detection runway required. This paper presents threshold marker method for monocular cameras introduces an on-board real-time implementation with flight test results. Results narrow wide field-of-view optics are compared. The processing also evaluated on data captured system. pure this increases redundancy because it does not require input from inertial as most detectors.
