Fusion and visualisation of the color and long wave infrared images of vegetation fires

The aspects of the image fusion and visualization of the color and long wave images are considered in the frame of the airborne reconnaissance and surveillance of the vegetation fires. The main constrains are consequence of the aerial platforms used: a) small lightweight aerial model (less than 5 kg, altitude up to 300 m above mean ground level, radius limited by visibility), b) helicopter or fixed wings piloted airplane. Although the measurements of the forest fire temperature are not reliable (unknown emissivity), its indication is possible and the fusion of the color image and the long wave infrared image seems the most suitable solution for firefighting commander.
