C3

← All Hardware

Underwater Stereo Camera: 12 MP color imaging with stereo depth estimation, pre-calibrated for three deployment configurations.

C3 trifocal stereo camera
// Overview

Stereo depth in a compact housing

The C3 pairs a 12 MP center color camera with dual 1 MP stereo cameras on a 7.5 cm baseline, enabling accurate depth estimation, species sizing, and 3D habitat reconstruction. Built around the Luxonis OAK-D S2 or OAK-D W PoE sensor module, pre-calibrated for underwater operations.

Available in three variants: the C3-BR integrates directly with the BlueROV2; the C3-MCBH8-POE is a standalone connectorized unit powered by PoE; and the C3-DBH13-UVC includes integrated UV-C antifouling lights for long-term fixed deployments. All variants are supported by Madrona and SaltySuite.

// Variants

Three deployment configurations

C3-BR

Designed for integration with the Blue Robotics BlueROV2. Pivoting mount adjusts viewing angle. Madrona software extension available for Cockpit.

C3-MCBH8-POE

Standalone connectorized C3 powered by PoE. Pivoting mounts and cable guards available. Suited for fixed or custom platform deployments.

C3-DBH13-UVC

Integrated UV-C antifouling lights maintain a clear viewport during extended long-term fixed station deployments.

// Features

Depth and color in one housing

  • Stereo depth estimation for accurate species sizing and 3D reconstruction
  • 12 MP center color camera for high-resolution documentation
  • Pre-calibrated for underwater deployment, ready out of the box
  • Optional I/O triggers for secondary cameras or lighting synchronization
  • UV-C antifouling variant for long-term fixed deployments without viewport degradation
  • POM housing with quartz lens: corrosion and biofouling resistant
  • SAE-4 vent port for pressure equalization
  • All variants supported by Madrona operator interface and SaltySuite platform
// Applications

Where the C3 is deployed

  • Species sizing: stereo baseline enables accurate length and biomass estimation
  • 3D habitat mapping: reconstruct benthic structure and rugosity from stereo imagery
  • Aquaculture: stock monitoring and biomass assessment without diver intervention
  • ROV and AUV integration: compact form factor fits most underwater vehicle frames
  • Fish passage monitoring: paired color and depth streams for counting and sizing
  • Fixed station monitoring: long-term deployment with UV-C antifouling variant
