Looming Aircraft Threats: Shape-based Passive Ranging of Aircraft from Monocular Vision
نویسندگان
چکیده
This paper proposes new techniques for aircraft shape estimation, passive ranging, and shapeadaptive hidden Markov model filtering which are suitable for a monocular vision-based noncooperative collision avoidance system. Visionbased passive ranging is an important missing technology that could play a significant role in resolving the sense-and-avoid problem in unmanned aerial vehicles (UAVs); a barrier hindering the wider adoption of UAVs for civilian applications. The feasibility of the proposed shape estimation, passive ranging and shape-adaptive filtering techniques is evaluated on flight test data.
