The system is designed to collect and process images of a surveyed zone from an airborne system, with the aim of detecting significant alterations in this zone. The system includes a photo-sensitive matrix camera(1) adapted to acquire sequentially successive image bands(Bi), of an overflown zone, in a series of narrow spectral windows. The system has a control unit (2) which includes a section for selecting images from a site in one or several spectral bands, each grouping a defined number of spectral windows. The respective width and spectral functions (F lambda ) can be modified, as desired, using logic, based upon the nature of the phenomena being analysed in the domain of a certain application. The system also includes a compensation arrangement for easily connecting the images shifted by variations in the trajectory of the aircraft. |
