Advancing Data Quality of Marine Archaeological Documentation Using Underwater Robotics: From Simulation Environments to Real-World Scenarios
Diamanti, Eleni; Yip, Mauhing; Stahl, Annette; Ødegård, Øyvind (Peer reviewed; Journal article, 2024)This paper presents a novel method for the visual-based 3D mapping of underwater cultural heritage sites through marine robotic operations. The proposed methodology addresses the three main stages of an underwater robotic ... -
Boundary artifact analysis in diffusion modelling with stochastic differential equations
Yip, Mauhing (Master thesis, 2019)In many research areas, it is common to model advection-diffusion problems with Lagrangian particle methods. This is the same as solving a stochastic differential equation, with drift and diffusion coefficients derived ... -
Creating a Synthetic Underwater Dataset for Egomotion Estimation and 3D Reconstruction
Zwilgmeyer, Peder Georg Olofsson (Master thesis, 2021)Denne oppgaven har som mål å lage et dataset fra et virituelt undervannsmiljø som inneholder bilder, sensordata og korrekt refereansedata. Dette gjøres i samarbeid med NTNUs "Autonomous Robots for Ocean Sustainability" ... -
Deep Monocular Depth Estimation for Autonomous Underwater Vehicles
Fagerli, Anders Thallaug (Master thesis, 2022)Å utforske og utnytte verdenshavene på en bærekraftig måte er avgjørende for å løse utfordringer som global oppvarming. Autonome undervannsroboter har som hensikt å erstatte menneskelige operatører i farlige undervannsmiljøer, ... -
Detecting and Suppressing Marine Snow for Underwater Visual SLAM
Hodne, Lars Martin; Leikvoll, Eirik; Yip, Mauhing; Teigen, Andreas Langeland; Stahl, Annette; Mester, Rudolf (Peer reviewed; Journal article, 2022)Conventional SLAM methods which work very well in typical above-water situations, are based on detecting key-points that are tracked between images, from which ego-motion and the 3D structure of the scene are estimated. ... -
Underwater Incremental Surface Reconstruction from Dynamic 3D Point Clouds
Schmidt, Magnus Stray (Master thesis, 2022)Autonome undervannsfarkoster (AUV-er) kan utvide vår tilgang til havene betydelig. For en AUV kan det være nødvendig å ha et kart omgivelsene for å gjennomføre noen typer oppgaver, som ruteplanlegging og kollisjonsunngåelse. ... -
The VAROS Synthetic Underwater Data Set: Towards realistic multi-sensor underwater data with ground truth
Zwilgmeyer, Peder Georg Olofsson; Yip, Mauhing; Teigen, Andreas Langeland; Mester, Rudolf; Stahl, Annette (Peer reviewed; Journal article, 2021)Underwater visual perception requires being able to deal with bad and rapidly varying illumination and with reduced visibility due to water turbidity. The verification of such algorithms is crucial for safe and efficient ...
