Automated corrosion surface quantification in steel transmission towers using UAV photogrammetry and deep convolutional neural networks

open access: yesComputer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Corrosion in steel transmission towers poses a challenge to structural integrity and safety, requiring efficient detection methods. Traditional visual inspections are unsustainable due to the complexity and volume of structures. Their manual, qualitative, and subjective nature often leads to inconsistencies in maintenance planning.

A displacement measurement methodology for deformation monitoring of long‐span arch bridges during construction based on scalable multi‐camera system

open access: yesComputer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract This study presents a scalable multi‐camera system (S‐MCS) for high‐precision displacement measurement and deformation monitoring of long‐span arch bridges during construction. Traditional methods such as robotic total stations (RTS) and single‐camera systems face limitations in dynamic scalability, synchronous multi‐point monitoring, and ...

A Multimethod Investigation of the Lake Agnes Rock Glacier, Colorado, USA

open access: yesPermafrost and Periglacial Processes, Volume 36, Issue 2, Page 217-229, April/June 2025.
ABSTRACT Rock glaciers are important headwater landforms that play a key role in alpine hydrology. North American rock glaciers are estimated to contain the third largest water volume equivalent globally, and over 3800 rock glaciers have been mapped in Colorado alone. However, these features are often overlooked in alpine water budgets.

Continuous Curvature Path Planning for Headland Coverage With Agricultural Robots

open access: yesJournal of Field Robotics, Volume 42, Issue 3, Page 641-656, May 2025.
ABSTRACT We introduce a methodology for headland coverage planning for autonomous agricultural robot systems, which is a complex problem often overlooked in agricultural robotics. At the corners of the headlands, a robot faces the risk to cross the border of a field while turning.

A Unified Topological Representation for Robotic Fleets in Agricultural Applications

open access: yesJournal of Field Robotics, Volume 42, Issue 3, Page 760-786, May 2025.
ABSTRACT Agricultural robots offer a viable solution to the critical challenges of productivity and sustainability of modern agriculture. The widespread deployment of agricultural robotic fleets, however, is still hindered by the overall system's complexity, requiring the integration of several nontrivial components for the operation of each robot but ...
