Wherein, described flame upper limit gray threshold and described flame lower limit gray threshold are used for the flame in image and background separation, and described red channel threshold value and described saturation degree threshold value are used for determining the flame image in rough sungpan monkshood root image further.
Wherein, described based in the forest fire detection platform of satellite remote sensing images, described reflector antenna 11 has the full hemisphere tracking power of X-band or S-band, for orientation-pitching mounting means, and be provided with wing drop mechanism, to solve the tracking problem that satellite crosses top, described display device is LCDs, described soundplay equipment is two-way speaker, for each pixel in described rough sungpan monkshood root image, described green channel value, described red value and described blue channel value are three color channel values in the RGB color space of described pixel, described saturation degree is red color channel value, in green channel value and blue channel value, the difference of maximal value and minimum value is divided by red color channel value, maximal value in green channel value and blue channel value.
In addition, the appearance of reflector antenna is the result that operating frequency of antenna improves constantly.Early stage Antenna Operation frequency range is shortwave, ultrashort wave (USW), and wavelength dimension is very large, and can not reflect as light, converge, therefore the principal mode of antenna is wire antenna, this be also " antenna " one the history of word originate.But along with the progress of technology, military requirement has greatly promoted the developing of the mankind in frequency space, enters microwave frequency band (300MHz ~ 3000GHz).
The wavelength of microwave is below 1 meter, and scattering properties is close with light, and therefore in optical field, early mature reflecting surface technology starts to be applied to microwave frequency band.At optical field, the reflecting surface technology that people grasp the earliest is Newtonian telescope (also claiming autocollimator), after this several typical autocollimator technology such as Cassegrain, Pascal Greggory has been grasped again, these technology are all obtain fine angular resolution by Enhanced Radiation Reduced Blast bore in itself, are used to field of antenna successively afterwards.The simplest reflector antenna and Newtonian telescope similar, a feed is placed in paraboloidal focus, forms the directional beam of high-gain.Cassegrain, Pascal Greggory reflection surface system are used for antenna, become the form of the main dual reflector antenna of two classes.
The extensive application of reflector antenna, except having benefited from improving constantly of frequency, also has benefited from the progress of feed technology.The feed of reflector antenna is the lower antenna of a gain, and generally adopt wire antenna in early days, as half-wave dipole, but this kind of antenna is as feed, and because directivity is very weak, energy leakage is a lot, can not improve the efficiency of reflector antenna.Adopt electromagnetic horn (being also the one of " aperture antenna ") as feed, better irradiation can be provided, especially the corrugated horn technology of generation nineteen sixty appearance later, the efficiency of reflector antenna is increased substantially, have also been enlarged the application of reflector antenna, become the main path obtaining high-gain.
In addition, traditional signal theory, is based upon on Fourier analysis foundation, and Fourier conversion is as a kind of change of overall importance, and it has certain limitation, if do not possessed localization analysis ability, can not analyzing non-stationary signal etc.People start to carry out various improvement, to improve this limitation, as STFT (short time discrete Fourier transform) to Fourier conversion in actual applications.Due to STFT adopt sliding window function just immobilize once selected, therefore determine its time frequency resolution and immobilize, do not possess adaptive ability, and wavelet analysis well solves this problem.
Wavelet analysis is a kind of emerging branch of mathematics, and he is the most perfect crystallization of functional, Fourier analysis, harmonic analysis, numerical analysis; In application, particularly in signal transacting, image procossing, speech processes and numerous nonlinear science field, he is considered to the another effective Time-Frequency Analysis Method after Fourier analyzes.Compared with wavelet transformation converts with Fourier, the local conversion being a time and frequency domain thus can information extraction from signal effectively, by calculation functions such as flexible and translations, multiscale analysis (Multiscale Analysis) is carried out to function or signal, solve Fourier and convert indeterminable many difficult problems.
Adopt the forest fire detection platform based on satellite remote sensing images of the present invention, not high for existing forest fire detection system detection efficiency, accuracy of detection is lower and lack graduation alarm mechanism technical matters, forest remote sensing image is obtained fast by satellite remote sensing mode, high-precision image recognition technology is used to improve the precision of flame image identification, set up the graduation alarm mode based on flame area size, thus saved the reflection processing time of forest management department, avoid spreading further of forest fire.
