Abstract This paper reports on the performance of a novel system for supporting search and rescue activities, known as SARUAV (search unmanned aerial vehicle), in field experiment during which real‐world scenario was simulated. The took place March 2–3, 2017, at two sites located southwestern Poland. Three groups acted experiment: (1) vehicle (UAV) operators, (2) ground searchers, (3) participants who simulated being lost. In uncomplicated topography without snow cover, identified lost...
Recent advances in search and rescue methods include the use of unmanned aerial vehicles (UAVs), to carry out monitoring terrains spot lost individuals. To date, such searches have been conducted by human observers who view UAV-acquired videos or images. Alternatively, persons may be detected automated algorithms. Although some algorithms are implemented software support activities, no successful case using detectors has reported on thus far scientific literature. This paper presents a...
We propose a simple geometrical approach for delineating region above which an Unmanned Aerial Vehicle (UAV) should fly to support the Search and Rescue (SAR) activities. The procedure is based on concept of crow's flight distance travelled by lost person its probability distribution, areas in there does not exist any SAR database that can be used estimate parameters such distribution. novelty lies indirect character, namely we do these but seek regions reveal comparable topographic settings...
Abstract A new method, named as the nested k‐means, for detecting a person captured in aerial images acquired by an unmanned vehicle (UAV), is presented. The k‐means method used newly built system that supports search and rescue (SAR) activities through processing of photographs taken visible light spectra (red‐green‐blue channels, RGB). First, classification utilized to identify clusters colors three‐dimensional space (RGB). Second, verify if automatically selected class concurrently...
The objective of this paper is to investigate the role clouds in effectiveness automated human detection aerial imagery acquired by unmanned vehicles (UAVs). processing carried out with nested k-means method applied images taken poor visibility caused low-altitude clouds. Data were during a field experiment Izerskie Mountains (southwestern Poland). fixed-wing UAV took RGB photographs terrain where persons simulated being lost wilderness. flights conducted morning and around noon, when...
In this paper, we report on a preliminary investigation into semi-empirical method for derivation of depth–age relationship oceanic lithosphere. The global 30-arcsecond bathymetry data from the General Bathymetric Charts Oceans (GEBCO) were corrected (1) sediment thickness using Total Sediment Thickness World’s and Marginal Seas (2) isostasy. was processed to obtain empirical bathymetric curve, solution computed with 50 m elevation bin. Subsequently, data-based curve approximated optimal...
We aim to investigate a potential impact of boosting saturation aerial imagery on the performance unsupervised human detection algorithms. The study is empirical since it based processing photographs taken during full year experiment in Izerskie Mountains (southwestern Poland) by consumer-grade Canon S110 camera mounted onboard eBee, fixed-wing micro-unmanned vehicle (UAV). In preliminary analysis, we used few basic color adjustments (sharpening, hue–saturation–luminance, contrast,...
