Citadel Panoramic: Situation Awareness Camera for Armoured VehiclesCST, Copenhagen Sensor Technology A/S
The Citadel CI-P170 is a panoramic camera system that combines images from two 85.5° field-of-view (FOV) cameras to a complete seamless 170° FOV viewing system for mounting on a wide variety of vehicles, such as armoured personnel carriers (APCs), light armour vehicles (LAVs) tanks and other wheeled or tracked vehicles.
It is designed to deliver high-performance images, even under the harshest conditions, in temperatures ranging between -40°C to +70°C.
The CI-P170 is designed around the latest generation 1/3in CCD image sensors and custom designed optics to provide a seamless, distortion-free panoramic 170° horizontal FOV image, without fish-eye effect, under a wide range of viewing conditions.
The camera design provides several viewing modes: 1. Full 170° Field of View, both cameras stitched together 2. Separate 85.5° Field of View from left or right side camera 3. 85.5° Field of View from the centre of both cameras
Ready for tough action
The CI-P170 is encased in a rugged IP-65 housing, designed to withstand vibration in accordance with MIL STD 810F(metal track vehicles). It is also sturdy enough to easily withstand the impact of soldiers' boots treading on the housing. Furthermore, with its low profile (78 mm), it is a difficult target for enemy snipers.
The camera protection windows are heated for condensation-free operation. In case of damage by scratching or cracking, a replacement window can easily bem fitted in the field.
The Citadel CI-P170 allows configuration of several graphic overlays in the form of distance markers and text strings.
The Citadel CI-P170 uses conductive cooling to remove heat from the CCD sensors. This reduces random noise in the CCD sensors, resulting in improved image quality, particularly in low-light conditions.
Expanded hi-dynamic range (XDR)
XDR is useful in conditions where there are large variations in brightness in the picture, i.e. when there are very dark and very bright areas in the picture. XDR amplifies the signal level in dark areas and reduces it in very bright areas thereby improving the visibility in the picture.
The fog penetration function is designed to automatically increase visibility under conditions such as fog, haze and fire smoke. The camera continuously analyses the picture and once it detects a low-contrast condition, it will automatically enhance the contrast.
Digital noise reduction (DNR)
The digital noise reduction in the CI-P170 camera is a function which analyses the video image and reduces the noise, particularly in low-light conditions. The analysis is based on a 3D algorithm.
