GUARD-1

Guard-1

Underwater Autonomous Smart Camera

GUARD-1 is a high resolution and high sensitivity intelligent underwater camera for coantent-based image recognition and classification. It is autonomous (battery operated), freely programmable frequency for time-lapse acquisition of images.
It is an intelligent imaging device conceived for the autonomous and stand-alone video-monitoring activities in remote marine environments and it is specifically designed for deployments extended in time. It has been conceived as equipment for mobile platforms (e.g. sea gliders, Argo Float vertical profilers, drifter buoys or autonomous underwater vehicles) as well as for fixed platforms like stand-alone or cabled observatories.
The imaging device acquires underwater images at a programmable time rate and provides on board content-based image analysis through customisable software. Depending on the application context the relevant information extracted from the acquired images, can be transferred outside the device through acoustic/satellite modems or through cabled connection.
