Abstract
Forward Looking Infrared (FLIR) sensors are potential components in hazard monitoring systems for general aviation aircraft. FLIR sensors can provide images of the runway area when normal visibility is reduced by meteorological conditions. We are investigating short wave infrared (SWIR) and long wave infrared (LWIR) cameras. Pre-recorded video taken from an aircraft on approach to landing provides raw data for our analysis. This video includes approaches under four conditions: clear morning, cloudy afternoon, clear evening, and clear night. We used automatic object detection techniques to quantify the ability of these sensors to alert the pilot to potential runway hazards. Our analysis is divided into three stages: locating the airport, tracking the runway, and detecting vehicle sized objects. The success or failure of locating the runway provides information on the ability of the sensors to provide situational awareness. Tracking the runway position from frame to frame provides information on the visibility of runway features, such as landing lights or runway edges, in the scene. Detecting small objects quantifies clutter and provides information on the ability of these sensors to image potential hazards. In this paper, we present results from our analysis of sample approach video.
