Ecotone AS UHI – Underwater Hyperspectral Imager
The UHI is a hyperspectral imager optimized for underwater use. The technology opens up an entirely new layer of detail in remote sensing previously only available for airborne-based platforms. With UHI, the field of hyperspectral imaging is now available for subsea applications. The UHI is capable of acquiring information in the entire visible color spectrum (370-800nm – adjustable). Data from the UHI can thus be used to detect biological and chemical characteristics of seafloor habitats.
Hardware for Underwater Hyperspectral Imaging
Our sensor makes it possible to collect and process hyperspectral light underwater, opening up a whole new world of subsea remote monitoring. Our hardware makes the entire hyperspectral light spectrum available for underwater research, monitoring, classifying and identifying of objects, areas and organisms.
Wider colour spectrums – more precise data
The sensor can gather data across the entire visible colour spectrum and the near infrared (370-800nm – with possibilities for further adjustments), which can be used to detect biological and chemical characteristics of seabed habitats.
The hyperspectral sensor we supply can be simply integrated with most modern ROV systems using standard industry couplings and cables. It can also be mounted and used on other devices used for underwater inspection and mapping.
Implementing the technology
The sensor is mounted with a clear field of vision to the seabed and flanked by dedicated lights and registers data as the vehicle moves. The data archive (hyperspectral analyses, navigation data and video) is saved locally, and can be uploaded to a surface vessel.
Software for Underwater Hyperspectral Imaging
Our system can be supplied complete with the software necessary to collect and pre-process data.
All data are saved in a structured archive file, and the software makes it possible to communicate with the unit.
The software includes the following functions:
- Live-viewing and collection of hyperspectral data (RGB and spectral) and 2D video stream in HD.
- Adjustment of spatial/spectral data collection.
- Adjustment of image frequency and integration time.
- Division, synchronising and storing of navigation data from ROV and GPS.
