Increasing research into aerial manipulation technology has widened the scope of possible applications for unmanned aircraft. One such application that is introduced in this paper is above-canopy sampling in forests. A preliminary study has investigated the problem experimentally as a means of determining a representative scenario whilst identifying key issues. These issues include relative position...
In this paper a novel algorithm for distant aircraft detection for visual sense-and-avoid for UAV is presented. The algorithm uses local edge density to partition the frame into two types of regions. The first type is the unstructured or homogeneous part like sky region and the second part where there is a structured background, like high contrast clouds or terrain regions. The airplanes are detected...
