Current railway tunnel inspections rely on expert operators performing a visual examination
of the entire infrastructure and manually annotating encountered defects. Automatizing the …

We present a novel FastSLAM approach for a robotic system inspecting structures made of
large metal plates. By taking advantage of the reflections of ultrasonic guided waves on the …

The inspection and maintenance of large-scale industrial structures are major challenges
that require time-efficient and reliable solutions to ensure the healthy condition of structures …

This paper presents a Graph-based Simultaneous Localization And Mapping (GraphSLAM)
approach for a robotic system relying on the reflections of ultrasonic guided waves to enable …

The inspection of sizeable plate-based metal structures such as storage tanks or marine
vessel hulls is a significant stake in the industry, which necessitates reliable and time …

The ultrasonic mapping of plate-based facilities is an essential step towards the robotic
inspection of large metal structures such as storage tanks or ship hulls. This work proposes …

Mapping a structure, such as a metal plate in a ship hull, using acoustic echoes typically
requires making assumptions on its shape (eg rectangular). This work introduces a more …
