AUTONOMOUS UNDERWATER VEHICLE IMAGING & LASER SYSTEM
The HUNTER II is CATHX’s fastest high-resolution imaging and measurement system.
Combining CATHX’s field-proven 4k colour camera, efficient strobe lights, and a new powerful laser imaging system. CATHX’s ultra-bright strobe LED panels provide HUNTER II with unparalleled image quality for stills data. The increased laser power enables improved accuracy at ranges of up to 7m, allowing for a wider swath path, resulting in more area surveyed. The enhanced laser imaging hardware provides more reliable measurement data while maintaining CATHX’s proven millimetre accuracy.
HUNTER II offers data connectivity to CATHX’s 2D and 3D visualisation and post-processing software. The rich imaging and measurement information and data connectivity offered by the HUNTER II provides features such as automated pipe-tracking and freespan detection.

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 up to 120,000 points and 60 lines per second from green 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, allow for high-speed AUV operation.
EXTENSIVE OPERATIONAL RANGE
- Operational heights of up to 7 metres (depending on system configuration and water conditions).
- 1:1 swath to height ratio, single-swath system, with swaths of up to 7 metres possible
HIGH PRECISION OUTPUTS
- High-resolution still and laser imaging enables millimetre precision. The system operates at distances up to 7 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 metadata, output in EXIF format, improves post-process workflow.
- Two-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 and laser 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 post processing software, optimises efficiencies.
