Voyis Completes NOAA AUV Payload Delivery

Written by Patricia Sestari

September 13, 2022


The Voyis team is excited to announce the recent delivery for the National Oceanic Atmospheric Administration (NOAA).  

NOAA is an American agency within the United States Department of Commerce. Its goal is to forecast weather, monitor oceanic and atmospheric conditions, chart the seas, conduct deep sea exploration, and manage fishing and protection of marine mammals and endangered species in the U.S. 

NOAA requested a self-contained laser and camera module for seamless integration within a new or existing Remus 600 Autonomous Underwater Vehicle (AUV) to accomplish subsea exploration and protection. One of the core objectives was to capture highly detailed  3D data collected using the laser system and crisp, even illuminated stills from the imaging solution within the field swappable module.  

With that in mind, Voyis delivered a complete solution which integrated our optical sensors into our Recon LS AUV payload for a Remus 600

The Solution  

The Recon LS AUV module consolidates Voyis’ industry leading laser scanning technology with high-speed, high-resolution stills imaging. The Recon LS builds off Voyis’ longstanding success with autonomous vehicle integrations and modulates the offering for smaller, versatile AUVs. The core components of the Recon LS are a laser scanner, and a 4K stills camera with lightbar. 

Recon LS – Laser Scanner  

Recon is using the architecture of the Insight Micro, packaging it in our Recon LS payload that works seamlessly for NOAA.  

The Recon LS laser scanner consists of a laser projector and an optical receiver to detect the line geometry on the seabed. The Recon LS Laser Scanner extracts multiple points along a laser light sheet rather than a single point from a laser beam.  

The key features and benefits of the Recon LS Laser Scanner: 

  • Provides 2464 data points per laser line capture 
  • High speed data captures, up to 85 Hz 
  • 50-degree underwater field of view for 50-degree laser coverage 
  • Optical filter to specifically focus on the laser colour spectrum, reducing impacts due to ambient light 
Recon LS – Camera & Lightbar 

The Recon LS camera is a colour camera with 4K resolution, real-time image enhancement and correction algorithms.  

Images are processed onboard, for resolving image distortions and optical aberrations ensuring rectilinear projections of images.  

The camera system is designed to operate in conjunction with the Recon LS laser scanning system to ensure seamless laser data and un-interrupted stills images. Images are PPS synchronized to the vehicle navigation systems and contain all positioning information within the image metadata to facilitate improved photomosaicing, photogrammetry, and improved target localization.  

The camera component is the same sensor used in the Recon 4K camera payload and is a standard package for the New Generation REMUS 100 and REMUS 300 vehicles. 

 The Recon LS lightbar is externally mounted and hydrodynamically designed to conform to the diameter of the REMUS 600. Designed with 32 LEDs oriented to provide maximum light uniformity for the Recon LS camera. The lightbar is synchronized with the Recon LS camera exposure and has a verified 500,000 Lumen output.
