Metrically Scaled Monocular Depth Estimation through Sparse Priors for Underwater Robots

ICRA 2024poster

In this work, we address the problem of real-time dense depth estimation from monocular images for mobile underwater vehicles. We formulate a deep learning model that fuses sparse depth measurements from triangulated features to improve the depth predictions and solve the problem of scale ambiguity.…

Underwater Hyperspectral Imaging for Measuring Seafloor Reflectance

IROS 2024poster

A known challenge for computer vision methods applied to the underwater domain is that nonlinear attenuation of light in underwater environments distorts the color signal in captured imagery, resulting in inconsistent color and contrast at varying distances to an imaged target. While surface reflect…
