Stable Position Measurement of a Moving Airplane by Adaptive Camera Control

Amethod is developed to identifya taxiing airplane and measure its position correctly under various lighting and weather conditionsby inputting a moving image from an adaptively-controlledcamera into an imageprocessor and analyzing the image inorder toguide theplane to the appointed parking spot. Since the airplanesare moved in outdoors,thereare many factors, such as varying sunlight levels, night lighting, and weather conditions like rain, that affect the input image and make it more difficultto accuratelyjudge the airplane'sposition. We propose an adaptive camera control system which controlsthe lensapertureand cameragain inorder toget the best image to extract the characteristicpoints accuratelyunder all condition. Cameraswith an ordinary aperture lens systems have too small a dynamic range to produce suitable input images because saturated pixels in a bright area and dark areas affect the brightnessof pixels adjacent to them. Our adaptive camera system converts radiance into g...
