Paper: A comparison between co-located UUV-based optical 3D reconstruction and interferometric bathymetry

Posted Leave a commentPosted in Product News, Research

Authors: Hunter C. Brown and Jeffrey Z. Snyder L3 OceanServer, Fall River, MA, 02723 Abstract—Seafloor bathymetry was traditionally measured with various mechanical means such as lead-lines or poles, and more recently has transitioned to acoustic methods using single beam altimeters, multibeam sonars, and interferometric sonars. New developments in structure-from-motion software have improved to a level […]

Author: Hunter C. Brown L3 OceanServer, Fall River, MA, 02723 Abstract – This paper reports the use of an autonomous underwater vehicle (AUV) with a Single-Board-Computer (SBC) to run both the L3 OceanServer Underwater Vehicle Console (UVC) software and a benchseat user-built secondary control system installed on a virtual-machine. Historically, a second computer has been […]

Optical Mosaicking and 3D Reconstruction aboard an Underway Iver3 UUV Authors: Hunter C. Brown, Jeffrey Z. Snyder L3 OceanServer, Fall River, MA, 02723 Abstract – Traditionally, Unmanned Underwater Vehicles (UUVs) serve as data recorders, collecting and storing data for post-processing after the mission is completed. Computer processing power aboard UUVs, however, has steadily increased to […]

This week, L3 OceanServer will be at the State of Lake Superior (SOLS) Conference at Michigan Technological University in Houghton, Michigan. The use of AUVs provides significant time savings compared to traditional sampling techniques. For example, the survey of outer Milwaukee Harbor using an AUV required less than 7 hours for approximately 600 water column […]
