Development of obstacle detection and avoidance system based on integration of different based-sensor for small-sized unmanned aerial vehicle using cues from expansion of feature points and direction of flow field vectors

Achieving a reliable obstacle detection and avoidance system that can provide an effective safe avoidance path for small unmanned aerial vehicle (UAV) is very challenging due to its physical size and weight constraints. Prior works tend to employ the vision based-sensor as the main detection sensor...
