Unique Technical Features Deliver Unparalleled Efficiencies

Fully integrated, single-swath system, delivering high-resolution still imaging and laser profiling.

Technical Features

PRECISION INTEGRATED IMAGING & MEASUREMENT

  • Still imaging – UHD stills resolution of 4096 x 2304 pixels up to 7 fps. HD stills resolution of 2048 x 1152 pixels up to 30 fps.
  • Laser imaging – Laser resolution of 100,000 points and 50 lines per second from green penetrating laser. Dense 3D laser point cloud data synchronised with stills in time and space.
  • Sequential imaging – 1 to 5 light pulses per millisecond, interleaved with laser and other sources, allow for high-speed AUV operation.

EXTENSIVE OPERATIONAL RANGE

  • Operational heights of 1 to 10 metres (depending on light configurations).
  • 1:1 swath to height ratio, single-swath system, with swaths of up to 10 metres possible

HIGH PRECISION OUTPUTS

  • High-resolution still and laser imaging enables millimetre precision. The system operates at distances up to 10 metres and speeds of up to 5 knots.

ADVANCED CALIBRATION

  • A fully calibrated system, including post-acquisition recalibration capability.

Efficiencies

WORKFLOW OPTIMISATION

  • Time-stamped, co-registered, fully integrated still, laser and video metadata, output in EXIF format, improves post-process workflow.
  • Three-pronged data collection and interrogation with other sensors produce further workflow efficiencies.

REDUCED OPERATION TIMES

  • High visibility and extended range enable non-stop, high-speed operations, delivering time and cost efficiencies.

REAL-TIME QUALITY ASSURANCE

  • Real-time still, laser and video data feeds allow instantaneous quality assurance and post-acquisition calibration, ensuring results are not compromised by misalignment or changes in environmental conditions

FULL COMPATIBILITY

  • Compatibility with clients’ existing workflows and with Cathx Ocean eventing, positioning and Solid software, optimises efficiencies in data processing.
