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 …

We review a range of techniques related to navigation of unmanned vehicles through
unknown environments with obstacles, especially those that rigorously ensure collision …

One of the primary challenges for autonomous robotics in uncertain and dynamic
environments is planning and executing a collision-free path. Hybrid dynamic obstacles …

This paper presents practical vision-based collision avoidance for objects approximating a
single point feature. Using a spherical camera model, a visual predictive control scheme …

With the increasing demand to integrate unmanned aircraft systems (UAS) into the National
Airspace System (NAS), new procedures and technologies are necessary to ensure safe …

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

This paper deals with constrained image-based visual servoing of circular and conical spiral
motion about an unknown object approximating a single image point feature. Effective visual …

This paper focuses on the problem of collision avoidance for Unmanned Aerial Vehicles
(UAVs). The dynamics of the UAV are modeled as a Dubins vehicle flying at constant …

This paper develops proportional navigation based guidance laws for UAV collision
avoidance in complex environments that may be characterized by multiple static and …

UAV teleoperation is a demanding task, especially for amateur operators who wish to
successfully accomplish their mission without collision. In this work we present an integrated …
