BlobBoards: Robust Markers for Accurate Pose
James Pritts, Till Sittart, Hendrik Sauer +4
We propose BlobBoards, a fiducial marker system comprising a dense, multi-scale field of Gaussian blobs and a feature-based pipeline for joint detection, identification, and pose e…
BALTIC: A Benchmark and Cross-Domain Strategy for 3D Reconstruction Across Air and Underwater Domains Under Varying Illumination
Michele Grimaldi, David Nakath, Oscar Pizarro +3
Robust 3D reconstruction across varying environmental conditions remains a critical challenge for robotic perception, particularly when transitioning between air and water. To addr…
Optical Ocean Recipes: Creating Realistic Datasets to Facilitate Underwater Vision Research
Patricia Schöntag, David Nakath, Judith Fischer +2
The development and evaluation of machine vision in underwater environments remains challenging, often relying on trial-and-error-based testing tailored to specific applications. T…
Relative Illumination Fields: Learning Medium and Light Independent Underwater Scenes
Mengkun She, Felix Seegräber, David Nakath +2
We address the challenge of constructing a consistent and photorealistic Neural Radiance Field in inhomogeneously illuminated, scattering environments with unknown, co-moving light…
Refractive COLMAP: Refractive Structure-from-Motion Revisited
Mengkun She, Felix Seegräber, David Nakath +1
In this paper, we present a complete refractive Structure-from-Motion (RSfM) framework for underwater 3D reconstruction using refractive camera setups (for both, flat- and dome-por…
Visual Tomography: Physically Faithful Volumetric Models of Partially Translucent Objects
David Nakath, Xiangyu Weng, Mengkun She +1
When created faithfully from real-world data, Digital 3D representations of objects can be useful for human or computer-assisted analysis. Such models can also serve for generating…
