Eurosatory 2014

See the best of both worlds (ES14E3)

18 June 2014

In the world of defence, different kinds of imaging sensors are needed for different light conditions. A ‘best of both worlds’ solution is what UK firm RFEL (Hall 5, Stand KJ395), in collaboration with KTK Kommunikationstechnik, GuS and Rheinmetall Defence, is launching at Eurosatory.

Their fully modular fDVE fused driver vision enhancement solution combines the benefits of current daylight camera sensors (mostly CCD) and computing technology for military use. It essentially creates a standardised mechanical and electric interface for different kinds of cameras/ sensor types.

As RFEL explains the problem, a daylight CCD sensor tends to be bad in low light, and virtually useless in darkness, while image intensifiers and thermal imaging sensors show less detail. Even ‘blending’ daylight and thermal imaging results in a loss of contrast and definition.

The image fusion (eg day/thermal) derives from RFEL’s state-ofthe- art fusion algorithm that processes images from two sensors, often from different wavelengths yet maintaining the best attributes from both inputs for the resulting output. RFEL claims it can be combined with image stabilisation even if the vehicle is subject to severe vibration.

The fDVE is based on RFEL’s HALO video processing solution, which is most suitable for ‘man-in-the-loop’ applications, such as driving, because of its minimal latency in video streaming. Some of the key benefits include image stabilisation, digital zoom, image overlay (such as picture in picture – PiP) and correction of lens distortion.
