A Calibration Tool for Refractive Underwater Vision
Felix Seegräber, Mengkun She, Felix Woelk +1
Many underwater applications rely on vision sensors and require proper camera calibration, i.e. knowing the incoming light ray for each pixel in the image. While for the ideal pinh…
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…
Semihierarchical Reconstruction and Weak-area Revisiting for Robotic Visual Seafloor Mapping
Mengkun She, Yifan Song, David Nakath +1
Despite impressive results achieved by many on-land visual mapping algorithms in the recent decades, transferring these methods from land to the deep sea remains a challenge due to…
