TRACKGRAPH: Online Open-Vocabulary 3D Scene Graphs via Image-Space Tracking
Peder Borge Hellesylt, Albert Gassol Puigjaner, Kostas Alexis +1
Open-vocabulary 3D maps enable robots to reason about previously unknown environments using natural language. However, existing systems typically segment every incoming image, asso…
IBPA: Real-time Free-form Manifold Mesh Reconstruction via Incremental Ball Pivoting with Integrated Hole Detection
Mauhing Yip, Mohit Singh, Kostas Alexis +2
Both Remotely Operated underwater Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) are frequently deployed to acquire geometric bathymetric data. However, it is often disc…
Caspar: CUDA Accelerator for Symbolic Programming with Adaptive Reordering
Emil Martens, Aaron Miller, Matias Varnum +1
We present Caspar, a library that makes the power of modern GPUs more accessible in robotics and provides a state-of-the-art nonlinear GPU solver that can be applied to a wide rang…
Patch Ensembles for Robust Salmon Re-Identification with Weak Trajectory Labels
Espen Uri Høgstedt, Christian Schellewald, Annette Stahl +1
Salmon re-identification in commercial net-pens is challenging due to large populations, which impose strict accuracy requirements and make large-scale labeled data acquisition inf…
Differential pose optimization in descriptor space -- Combining Geometric and Photometric Methods for Motion Estimation
Andreas L. Teigen, Annette Stahl, Rudolf Mester
One of the fundamental problems in computer vision is the two-frame relative pose optimization problem. Primarily, two different kinds of error values are used: photometric error a…
A Multi-purpose Tracking Framework for Salmon Welfare Monitoring in Challenging Environments
Espen Uri Høgstedt, Christian Schellewald, Annette Stahl +1
Computer Vision (CV)-based continuous, automated and precise salmon welfare monitoring is a key step toward reduced salmon mortality and improved salmon welfare in industrial aquac…
PyGemini: Unified Software Development towards Maritime Autonomy Systems
Kjetil Vasstein, Christian Le, Simon Lervåg Breivik +3
Ensuring the safety and certifiability of autonomous surface vessels (ASVs) requires robust decision-making systems, supported by extensive simulation, testing, and validation acro…
Near-Shore Mapping for Detection and Tracking of Vessels
Nicholas Dalhaug, Annette Stahl, Rudolf Mester +1
For an autonomous surface vessel (ASV) to dock, it must track other vessels close to the docking area. Kayaks present a particular challenge due to their proximity to the dock and…
Robust Hole-Detection in Triangular Meshes Irrespective of the Presence of Singular Vertices
Mauhing Yip, Annette Stahl, Christian Schellewald
In this work, we present a boundary and hole detection approach that traverses all the boundaries of an edge-manifold triangular mesh, irrespectively of the presence of singular ve…
Removing Adverse Volumetric Effects From Trained Neural Radiance Fields
Andreas L. Teigen, Mauhing Yip, Victor P. Hamran +3
While the use of neural radiance fields (NeRFs) in different challenging settings has been explored, only very recently have there been any contributions that focus on the use of N…
RGB-D Mapping and Tracking in a Plenoxel Radiance Field
Andreas L. Teigen, Yeonsoo Park, Annette Stahl +1
The widespread adoption of Neural Radiance Fields (NeRFs) have ensured significant advances in the domain of novel view synthesis in recent years. These models capture a volumetric…
