Small rotary-winged unmanned aerial vehicles or “drones” mounted with a small video camera were successful in surveying the nest contents of four species of raptor, including Osprey (Pandion haliaetus), Bald Eagle (Haliaeetus leucocephalus), Ferruginous Hawk (Buteo regalis), and Red-tailed Hawk (B. jamaicensis) in an accurate and safe manner when the proper flight technique was employed. A total of 110 surveys were completed in 2013 and 2014 with quality images of nest contents obtained in 106 or (96.4%) of flights. A successful and safe flight requires two personnel: the pilot who controls the aircraft and the spotter who monitors the behaviour of the adult birds defending the nest and keeps the pilot updated on all potentially dangerous interactions between aircraft and the birds. With the video camera recording, the aircraft is flown above the nest to a predetermined location that allows an unobscured camera shot of the nest. This technique can be readily adapted to a variety of habitat types and species. The accuracy of data obtained combined with the flexibility, low cost, and speed of this technique make it a useful technological alternative to the safety risks and obtrusiveness associated with traditional survey techniques.

With the accelerated use of our national parks there is growing concern over the impact this increased visitation might have on their flora and fauna. For this reason it is important to gather baseline data on the biota for future management and interpretive programs. Two species of concern in Grand Teton National Park are the bald eagle (Haliaeetus leucocephalus) and osprey (Pandion haliaetus).

The Status

Yellowstone National Park funded a research study conducted by Jon Swenson from 1972 through 1974 on the ecology of the bald eagle (Haliaeetus leucocephalus) and osprey (Pandion haliaetus). The present study was initiated to further the information on the ecology of the bald eagle and osprey in Grand Teton National Park and to obtain comparative data to that obtained by Swenson from Yellowstone National Park.

A small rotary-winged unmanned aerial vehicle (UAV) was flown above the nests of four raptor species: osprey (Pandion haliaetus), bald eagle (Haliaeetus leucocephalus), ferruginous hawk (Buteo regalis), and red-tailed hawk (B. jamaicensis) to document the parental nest defense response to the aircraft. Adult behaviour was documented with a voice recorder and an ethogram, starting ~100 m distant from the nest and continuing until the base of the nest was reached, the survey completed, and the nest area exited. All adult movements and vocalizations were recorded with distance of bird and researchers from the nest when a given behaviour occurred. Ospreys showed the strongest nest defense response followed by ferruginous hawks and red-tailed hawks with bald eagles showing the least aggressive response. Ospreys showed no greater response to the UAV in the air near the nest than to researchers simply standing at the base of the nest structure, while bald eagles showed a significantly higher response to the aircraft than researchers at the nest base. Although aggression varied, no species showed aggression at levels that would discourage the use of UAVs to survey raptor nests. When a proper flight technique is adopted, UAVs can offer a useful tool for surveying raptor nests.

Unmanned aerial vehicles (UAVs) have gained their prevalent recognition in construction because of their exceptional advantages. Despite the increasing use of UAVs in the industry and their remarkable benefits, there are serious potential safety risks associated that have been overlooked. Construction is one of the most hazardous industries in the United States. In addition to the ordinary hazards normally present in dynamic construction workplaces, UAVs can expose workers to a wider range of never-before-seen safety risks that must be recognized and controlled. The industry is not equipped with safety measures to prevent potential accidents, because of scarce research on drone-associated hazards and risks. The aim of this research was to (1) identify the UAV-associated hazards in construction that may expose personnel and property to potential harms, and (2) study the relative impact of each hazard and the associated safety risks. In Phase I, the researchers conducted an extensive literature review and consulted with a construction UAV expert. In Phase II, the researchers obtained data from 54 construction experts validating and evaluating the identified hazards and risks. The results revealed that adopting UAVs can expose construction projects to a variety of hazards that the industry is not familiar with. “Collision with properties,”“collision with humans,” and “distraction” were identified as the top three safety risks. Moreover, the study introduces effective strategies, such as having qualified crew members, proper drone model selection, and drone maintenance, to mitigate the safety risks. Finally, a post-hoc case study was investigated and presented in this article.

Performance Results

There are many scenarios where high resolution, wide field of view video is useful. Such panorama video may be generated using camera arrays where the feeds from multiple cameras pointing at different parts of the captured area are stitched together. However, processing the different steps of a panorama video pipeline in real-time is challenging due to the high data rates and the stringent timeliness requirements. In our research, we use panorama video in a sport analysis system called Bagadus. This system is deployed at Alfheim stadium in Tromsø, and due to live usage, the video events must be generated in real-time. In this paper, we describe our real-time panorama system built using a low-cost CCD HD video camera array. We describe how we have implemented different components and evaluated alternatives. The performance results from experiments ran on commodity hardware with and without co-processors like graphics processing units (GPUs) show that the entire pipeline is able to run in real-time.
