摘要： An onboard aircraft landing system includes one or more event-based cameras (104) disposed at known locations to capture the runway and visible surrounding features such as lights and runway markings. The event-based cameras (104) produce a continuous stream of event data that may be quickly processed to identify both light and dark features contemporaneously, and calculate an aircraft pose relative to the runway based on the identified features and the known locations of the event-based cameras. Composite features are identified via the relative location of individual features corresponding to pixel events.

摘要： A system and method (600) are provided for automatically adjusting exposure to maintain color fidelity where a point source puts a small cluster of pixels in saturation. An exposure level is iteratively reduced until pixels corresponding only one color in a Bayer filter (108) remain above a threshold while all other colors are at or below the threshold. The cluster of pixels is isolated for analysis such that only neighboring pixels are considered while reducing the exposure.
