A method and device for fire detection

摘要

Method and system for detecting by specific processing of images of a region overflown, taken in a plurality of spectral bands of signs indicative of a stress of the vegetation and the presence of spots propitious to the rise of the fire or to its propagation. & br / is acquired by means of a device for taking views (1), the images of the region overflown, in a first selected spectral band in the red part (r) of the visible spectrum, in a second spectral band of the near infrared (nir), and in a third spectral band in the thermal infrared chosen in order to identify parts of the zone having both a hydric stress and points more or less hot, the shape of the coded composite images obtained by a color coding for example, of the aforementioned spectral bands and it is possible to combine the images obtained in the three spectral bands, by means of a processing system (12, 13), highlighting the risk of developing caused by this deficit and local overheating. & br / application to the provision, the prevention and the action of the fire, for example.
