This paper provides a comprehensive review of the vision-based See and Avoid problem for
unmanned aircraft. The unique problem environment and associated constraints are …

In search and monitoring tasks, object traversing scenarios are more challenging than
avoidance and tracking. In this paper, we propose an object perception and path planning …

IN recent years, worldwide research for integration of Unmanned Aerial Vehicles (UAVs) in
Civil Airspace has increased considerably [1–4]. Several organizations for the development …

Presented here is an analysis of an extensive flight campaign aimed at characterizing
peculiarities, advantages, and limitations of an obstacle detection and tracking system …

The sense and avoid capability is one of the greatest challenges that has to be addressed to
safely integrate unmanned aircraft systems into civil and nonsegregated airspace. This …

This paper describes a vision-based sense-and-avoid framework to detect approaching
aircraft especially observed with cluttered background. The proposed framework consists of …

This paper proposes an image processing algorithm for 'sense-and-avoid'of aerial vehicles
in short-range at low altitude and shows flight experiment results. Since it can suppress the …

This paper provides a preliminary analysis of an autonomous uncooperative collision
avoidance strategy for unmanned aircraft using image-based visual control. Assuming target …

Background There is a rapidly growing need to operate both military and civil Unmanned
Aircraft Systems (UAS) in the same airspace as manned aircraft–particularly outside of …

This paper presents a fully Automatic Collision Avoidance System (ACAS) for unmanned
aerial vehicles. This system has been developed by the Italian Aerospace Research Center …
