The invention provides a method and a
system for detecting forest fire. The
system is composed of a forest monitoring point which comprises a heavy-duty digital
tripod head 1, a
thermal infrared imager 2, a visible light camera 3, a micro-meteorological
station 4, embedded
video processing equipment 5 and a communication bridge 6, and a
command and control center which comprises a telemonitoring computer 7 and a communication bridge 8, wherein, the two communication bridges are communicated by a
microwave wireless Tcp / IP network. The
fire detection work is sequentially performed by the following six major steps: (1)
field data acquisition, (2) image
data processing, (3) fire recognition and analysis, (4) transmission of recognition results, (5) fire
probability assessment and (6) automaticfire early warning. The method and the
system combines video compression and decompression technology,
thermal infrared image recognition and analysis technology, visible light
color image recognition and analysis technology,
embedded technology,
wireless communication technology,
remote sensing (RS) technology and 3D
geographic information system technology to automatically recognize forest fireand analyze fire strategies, thus the method and the system are characterized by high detection probability of forest fire, low
false alarm rate, no artificial participation, strong timeliness, highreliability, advanced technological means and wide market prospects.
