Advanced computer vision for extracting georeferenced vehicle trajectories from drone imagery [PDF]

arXiv
This paper presents a framework for extracting georeferenced vehicle trajectories from high-altitude drone imagery, addressing key challenges in urban traffic monitoring and the limitations of traditional ground-based systems. Our approach integrates several novel contributions, including a tailored object detector optimized for high-altitude bird's ...

Empirical Quantification of Topobathymetric Lidar System Resolution Using Modulation Transfer Function

Earth and Space Science, Volume 12, Issue 4, April 2025.
Abstract Topobathymetric scanning lidar deployed on unmanned aircraft systems is a powerful tool for high‐resolution mapping of the dynamic interface between topography and bathymetry. However, standardized methods for empirical resolution validation have not been widely adopted across lidar applications.

Fishers' interactions with endangered “rhinorays” in Karimunjawa National Park, and factors influencing willingness to engage in pro‐conservation behavior

Conservation Science and Practice, Volume 7, Issue 4, April 2025.
Abstract The “rhinorays” (giant guitarfish‐Glaucostegidae and wedgefish‐Rhinidae) are a critically endangered group of “shark‐like rays,” which have experienced steep global population declines in the past decade due to overfishing. Their slow life histories and high market value increase the risk of trade‐driven extinction and lead to trade‐offs ...

Texture2LoD3: Enabling LoD3 Building Reconstruction With Panoramic Images [PDF]

arXiv
Despite recent advancements in surface reconstruction, Level of Detail (LoD) 3 building reconstruction remains an unresolved challenge. The main issue pertains to the object-oriented modelling paradigm, which requires georeferencing, watertight geometry, facade semantics, and low-poly representation -- Contrasting unstructured mesh-oriented models.
