Ballenas jorobadas cerca del banco Stellwagen
La gracia de una enorme ballena capta la atención de casi todos los que alguna vez han visto una. Estas increíbles criaturas son el foco de las industrias turísticas de todo el mundo y han capturado los corazones de niños y adultos por igual. Desafortunadamente, la mayoría de las poblaciones de mamíferos marinos son frágiles. Una de las principales causas de muerte de las grandes ballenas es el choque con barcos y el objetivo de estas regulaciones es proteger a estos animales del impacto humano (ya sea muerte, lesión o incluso simplemente un cambio de comportamiento). Mientras el mundo busca nuevas tecnologías para ayudar a evitar a las ballenas, es importante que no tengan

Improving results with refraction corrections
Accurate bathymetric mapping of shallow areas is essential for many offshore activities. Through Structure from Motion (SfM) and Multiview Stereo (MVS) techniques, images can provide a low-cost alternative compared to Lidar and sonar systems while offering important visual information. This article presents a new framework for mapping the seabed in clear and calm shallow waters for small- and large-scale surveys using aerial imagery and machine learning to correct the geometric effects of refraction on the 3D point clouds and the imagery.
SfM is a photogrammetric technique for estimating 3D structures from 2D image sequences. It involves acquiring images from several positions relative to the object of interest. To establish
