A Survey of Design Considerations of Optical Imaging Stabilization Systems for Small Unmanned Aerial Systems
Rodin, Christopher D; Andrade, Fabio; Hovenburg, Anthony Reinier; Johansen, Tor Arne (Journal article; Peer reviewed, 2019)Optical imaging systems are one of the most common sensors used for collecting data with small Unmanned Aerial Systems (sUAS). Plenty of research exists which present custom-made optical imaging systems for specific missions. ... -
Accuracy of Sea Ice Floe Size Observation from an Aerial Camera at Slant Angles
Rodin, Christopher D; Johansen, Tor Arne (Chapter; Peer reviewed, 2017)The importance of measuring the size of ice floes in e.g. marine navigation and environmental sciences has made it a frequently performed procedure. When real-time data is required, images from a camera on-board an aerial ... -
Autonomous Unmanned Aerial Vehicles in Search and Rescue Missions Using Real-Time Cooperative Model Predictive Control
Andrade, Fabio; Hovenburg, Anthony Reinier; de Lima, L. N.; Rodin, Christopher D; Johansen, Tor Arne; Storvold, Rune; Correia, Carlos; Haddad, Diego (Journal article; Peer reviewed, 2019)Unmanned Aerial Vehicles (UAVs) have recently been used in a wide variety of applications due to their versatility, reduced cost, rapid deployment, among other advantages. Search and Rescue (SAR) is one of the most prominent ... -
Contingency Path Planning for Hybrid-electric UAS
Hovenburg, Anthony Reinier; Andrade, Fabio; Rodin, Christopher D; Johansen, Tor Arne (Chapter, 2017)This article presents a path planning optimization method which aims to mitigate the risks in the event of a critical engine or generator failure in hybrid-electric UAS. This is achieved through continuous determination ... -
Detectability of Objects at the Sea Surface in Visible Light and Thermal Camera Images
Rodin, Christopher D; Johansen, Tor Arne (Chapter, 2018)In a number of ocean surveillance and remote sensing applications, visible light and thermal cameras are used to detect and identify objects at the sea surface. Knowing beforehand what the camera can detect or not can be ... -
Long range path planning using an aircraft performance model for battery powered sUAS equipped with icing protection system
Hovenburg, Anthony Reinier; Andrade, Fabio; Hann, Richard; Rodin, Christopher D; Johansen, Tor Arne (Journal article, 2020)Earlier studies demonstrate that en-route atmospheric parameters, such as winds and icing conditions, significantly affect the safety, and in-flight performance of unmanned aerial systems. Nowadays, the inclusion of ... -
Object Classification in Thermal Images using Convolutional Neural Networks for Search and Rescue Missions with Unmanned Aerial Systems
Rodin, Christopher D; de Lima, L. N.; Andrade, Fabio; Haddad, D. B.; Johansen, Tor Arne; Storvold, Rune (Journal article; Peer reviewed, 2018)In recent years, the use of Unmanned Aerial Systems (UAS) has become commonplace in a wide variety of tasks due to their relatively low cost and ease of operation. In this paper, we explore the use of UAS in maritime Search ... -
Path Planning of Multi-UAS Communication Relay by Decentralized MPC
Andrade, Fabio; Rodin, Christopher D; Hovenburg, Anthony Reinier; Johansen, Tor Arne; Storvold, Rune (Chapter, 2018)When using Autonomous Surface Vehicles (ASV) in marine operations, long distances and/or low power transmissions may severely limit the communication between the ASV and the ground station. One solution to overcome this ...
