A cooperative track-before-detect algorithm for multiple ground targets is presented for fixed-wing Unmanned Air Vehicles (UAVs) with a finite field of view. The road network forms a graph whose nodes indicate the target likelihood ratio. Target observations are assimilated by a Bayesian likelihood ratio tracker in which likelihood diffuses according to the graph Laplacian of the road network. Using...
Unmanned Air Vehicles (UAVs), which have been popular in the military context, have recently attracted attention of many researchers because of their potential civilian applications. However, before UAVs can fly in civilian airspace, they need to be able to navigate safely to its goal while maintaining separation with other manned and unmanned aircraft during the transit. Algorithms for autonomous...
This paper discusses the machine vision element of a system designed to allow automated taxiing for Unmanned Aerial System (UAS) around civil aerodromes. The purpose of the computer vision system is to provide direct sensor data which can be used to validate vehicle position, in addition to detect potential collision risks. This is achieved through the use of a singular monocular sensor. Untrained...
