Book excerpt: This research aims to show Unmanned Aerial System (UAS) and Structure-from-Motion (SfM) technology can, in combination, improve on traditional large wood (LW) monitoring techniques. More temporally and economically efficient data collected at a finer spatial resolution and greater spatial extent will increase the effectiveness of management plans and risk assessment for LW by providing decision-makers with a complete picture of the river. Contemporary practices are too inefficient in time and labor for large-scale monitoring of fluvial LW with anything more than the most general management or risk assessment in mind. The paradigm of river research, the river continuum concept (RCC), where a river's traits are interpolated between discrete study areas, has shifted to a nested hierarchical structure (Woodget et al., 2017). The nested hierarchical structure paradigm demands higher temporal and spatial resolution combined with greater spatial extent for LW data, as called for in Zorn et al. (2018). This study revealed UAS-SfM as a plausible option for creating data products capable of enhancing LW monitoring and risk assessment. Orthomosaics of a higher resolution (2.34cm/pixel) than those available via commercially available imagery and a 3D point cloud were both useful for general identification of LW, but both were subject to noise and errors. The sources of the noise and errors were the camera angles used during image collection, overhanging vegetation, and deep water. Changes to data collection techniques can alleviate these issues.

Book Synopsis Safety And Reliability In Cooperating Unmanned Aerial Systems by : Camille Alain Rabbath
Download or read book Safety And Reliability In Cooperating Unmanned Aerial Systems written by Camille Alain Rabbath and published by World Scientific. This book was released on 2010-01-25 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of recent advances in the analysis and design of health management systems for cooperating unmanned aerial vehicles. Such systems rely upon monitoring and fault adaptation schemes. Motivation for their study comes from the fact that, despite the use of fault-tolerant control software and hardware embedded onboard air vehicles, overall fleet performance may still be degraded after the occurrence of anomalous events such as systems faults and failures. Cooperative health management (CHM) systems seek to provide adaptation to the presence of faults by capitalizing on the availability of interconnected computing, sensing and actuation resources.This monograph complements the proposed CHM concepts by means of case studies and application examples. It presents fundamental principles and results encompassing optimization, systems theory, information theory, dynamics, modeling and simulation. Written by pioneers in cooperative control, health management and fault-tolerant control for unmanned systems, this book is a unique source of information for designers, researchers and practitioners interested in the field.

Book Synopsis Forestry Applications of Unmanned Aerial Vehicles (UAVs) 2019 by : Alessandro Matese
Download or read book Forestry Applications of Unmanned Aerial Vehicles (UAVs) 2019 written by Alessandro Matese and published by MDPI. This book was released on 2020-11-23 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unmanned aerial vehicles (UAVs) are new platforms that have been increasingly used in the last few years for forestry applications that benefit from the added value of flexibility, low cost, reliability, autonomy, and capability of timely provision of high-resolution data. The main adopted image-based technologies are RGB, multispectral, and thermal infrared. LiDAR sensors are becoming commonly used to improve the estimation of relevant plant traits. In comparison with other permanent ecosystems, forests are particularly affected by climatic changes due to the longevity of the trees, and the primary objective is the conservation and protection of forests. Nevertheless, forestry and agriculture involve the cultivation of renewable raw materials, with the difference that forestry is less tied to economic aspects and this is reflected by the delay in using new monitoring technologies. The main forestry applications are aimed toward inventory of resources, map diseases, species classification, fire monitoring, and spatial gap estimation. This Special Issue focuses on new technologies (UAV and sensors) and innovative data elaboration methodologies (object recognition and machine vision) for applications in forestry.

Available in PDF, EPUB and Kindle. Book excerpt: Riparian vegetation restoration efforts demand cost effective, accurate, and replicable impact assessments. In this thesis a method is presented using an Unmanned Aerial Vehicle (UAV) equipped with a GoPro digital camera to collect photogrammetric data of a 2.02-acre riparian restoration. A three-dimensional point cloud was created from the photos using Structure from Motion (SfM) techniques. The point cloud was analyzed and compared to traditional, ground-based monitoring techniques. Ground truth data collected using the status-quo approach was collected on 6.3% of the study site and averaged across the entire site to report stem heights in stems/acre in three height classes, 0-3 feet, 3-7 feet, and greater than 7 feet. The project site was divided into four analysis sections, one for derivation of parameters used in the UAV data analysis, and the remaining three sections reserved for method validation. The most conservative of several methods tested comparing the ground truth data to the UAV generated data produced an overall error of 21.6% and indicated an r2 value of 0.98. A Bland Altman analysis indicated a 99% probability that the UAV stems/plot result will be within 159 stems/plot of the ground truth data. The ground truth data is reported with an 80% confidence interval of +/- 844 stems/plot, thus the UAV was able to estimate stems well within this confidence interval. Further research is required to validate this method longitudinally at this same site and across varying ecologies. These results suggest that UAV derived environmental impact assessments at riparian restoration sites may offer competitive performance and value.

Book Synopsis Recent Advances in Research on Unmanned Aerial Vehicles by : Fariba Fahroo
Download or read book Recent Advances in Research on Unmanned Aerial Vehicles written by Fariba Fahroo and published by Springer. This book was released on 2013-04-10 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: A team of launched and coordinated Unmanned aerial vehicles (UAVs), requires advanced technologies in sensing, communication, computing, and control to improve their intelligence and robustness towards autonomous operations. To enhance reliability, robustness, and mission capability of a team of UAVs, a system-oriented and holistic approach is desirable in which all components and subsystems are considered in terms of their roles and impact on the entire system. This volume aims to summarize the recent progress, identify challenges and opportunities, and develop new methodologies and systems on coordinated UAV control. A group of experts working in this area have contributed to this volume in several related aspects of autonomous control of networked UAVs. Their papers introduce new control methodologies, algorithms, and systems that address several important issues in developing intelligent, autonomous or semi-autonomous, networked systems for the next generation of UAVs. The papers share a common focus on improved coordination of the members of the networked system to accomplish a common mission, to achieve heightened capability in system reconfiguration to compensate for lost members or connections, and to enhance robustness against terrain complications and attacks.

This book was released on 2018 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: When discussing the risk of introducing drones into the National Airspace System, it is necessary to consider the increase in risk to people in manned aircraft and on the ground as well as the various ways in which this new technology may reduce risk and save lives, sometimes in ways that cannot readily be accounted for with current safety assessment processes. The Committee on Assessing the Risks of Unmanned Aircraft Systems (UAS) Integration examined the various ways that risk can be defined and applied to integrating UAS into the National Airspace System managed by the Federal Aviation Administration (FAA). The committee looked at recent developments in this field and consulted numerous experts in academia, industry, and government. The committee developed 11 recommendations that are presented in this report.
