ABSTRACT: In this
paper, a study and evaluation of the combination of GPS/GNSS techniques and
advanced image processing algorithms for distressed human detection,
positioning and tracking, from a fully autonomous Unmanned Aerial Vehicle
(UAV)-based rescue support system, are presented. In particular, the issue of human detection both on
terrestrial and marine environment under several illumination and background
conditions, as the human silhouette in water differs significantly from a
terrestrial one, is
addressed. A robust approach, including an adaptive distressed human detection
algorithm running every N input image frames combined with a much faster
tracking algorithm, is proposed. Real time or near-real-time distressed human
detection rates achieved, using a single, low cost day/night NIR camera mounted
onboard a fully autonomous UAV for Search and Rescue (SAR) operations. Moreover,
the generation of our own dataset, for the image processing algorithms training
is also presented. Details about both hardware and software configuration as
well as the assessment of the proposed approach performance are fully
discussed. Last, a comparison of the proposed approach to other human detection
methods used in the literature is presented.
