Obtain, be only spliced into a complete image, the underlying surface mean temperature in the region to be detected could be obtained.
Before splicing to multiple infrared images in each region to be detected, it is also necessary to each region to be detected
The multiple infrared image carries out geometric correction and radiant correction.When remotely sensed image, due to the posture of aircraft, height,
The influence of the factor such as speed and earth rotation, cause image that geometric distortion, this distortion performance occurs relative to ground target
Extruding, distortion, stretching and skew etc., the mistake carried out for geometric distortion occurs relative to the physical location of ground target for pixel
Difference correction is just named geometric correction.Typically correct and eliminate when remote sensing image is imaged because of material of photographing by a series of mathematical modeling
Expect deformation, object lens distortion, Atmosphere Refraction, earth curvature, earth rotation, hypsography etc. various regions on original image caused by factor
The features such as the geometric position of thing, shape, size, orientation and the expression in reference system deform caused by requiring inconsistent.
The geometric correction of remote sensing image has 3 kinds of schemes at present, i.e., system compensation, using controlling point calibration and composed correction.
Radiant correction refers to due to extraneous factor, system caused by data acquisition and Transmission system, random radiation
The correction that distortion or distortion are carried out, eliminates or corrects the process for causing image distortion because of radiation error.Remote sensing image produces spoke
The factor for penetrating error (i.e. tonal distortion) mainly has：1. scattering and absorption of the air to electromagenetic wave radiation；2. altitude of the sun is with passing
The change of sensor viewing angle；3. change in radiation intensity caused by hypsography；4. sensor detection system performance difference, such as optics
The difference of system or different detectors in sensitivity, spectral response and light transmission；5. image processing, such as photograph processing.
Image greyscale distortion is relevant with image space frequency.Spatial frequency is higher, i.e., target is cured hour, and radiation error is bigger.Radiate school
Just it is being actually a content of image restoration.Correcting mode has two classes：1. sensor radiation corrects.Generally use internal calibration
Light source and calibration wedge, such as the radiant correction of Landsat multispectral scanner；2. image radiometric distortions correction.Frequently with physics or
Mathematics (calibration curve or various algorithms) method, such as space filtering, smoothing, correct various tonal distortions and fault, grey point, bar
The radiation error of the discrete form of line, signal deletion equal distribution on whole image.Wherein the correction of atmospheric effect can also pass through
Reflected radiation flux and image density are surveyed, and regression analysis is carried out to data to be corrected.
The underlying surface that each region to be detected is calculated in the complete image in each region to be detected of S2032, basis is averaged
Temperature.
The landscape characteristics that every width infrared image is got are differed, and multiple infrared images are being spliced into one completely
During image, then the underlying surface mean temperature according to corresponding to obtaining complete image is needed.
S2033, obtained according to underlying surface mean temperature, weather information and the preparatory condition in each region to be detected and each treated
The surface air temperature of detection zone.
Under conditions of choosing summer cloudless fine day, and wind speed<4.5m/s data are valid data, and preparatory condition is：Under
It is constant to meet linear relationship Ts=a+bTa, a and b between pad face mean temperature Ts and surface air temperature Ta, by above-mentioned
Surface air temperature Ta can be calculated in formula.
S2034, the surface air temperature according to each region to be detected and each region to be detected of suburb temperature acquisition
Heat Island.
Heat Island H is underlying surface mean temperature Ts and suburb temperature Tc difference, H=Ta-Tc, according to the size of H values
To evaluate city tropical island effect.
S204, Back ground Information and Heat Island to key area carry out comprehensive analysis, and it is strong with heat island to obtain Back ground Information
Interaction relationship between degree.
Back ground Information and Heat Island to key area carry out com-parison and analysis, and the interaction obtained between the two is closed
System, and the size of relation, Back ground Information include：Geographical location information, vegetation information, hydrographic information, architecture information, population are close
Spend information and transport information.
S205, the urban planning suggestion for determining according to interaction relationship city to be detected.
If the size effect of vegetation information and hydrographic information to Heat Island is very big, urban planning can carried out
When, consider to add or reduce vegetation and water body in designated area, city temperature is adjusted by adjusting Heat Island.
A kind of urban planning method provided in an embodiment of the present invention, in the case that weather in weather information is suitable, lead to
The relation crossed between underlying surface mean temperature and surface air temperature and the underlying surface mean temperature being calculated are calculated
Surface air temperature, the Heat Island in each region to be detected is the difference of surface air temperature and suburb temperature, hot
Island intensity can be used for evaluating tropical island effect, and the strong region of tropical island effect is analyzed as key area, obtains emphasis area
Interaction relationship between the Back ground Information and Heat Island in domain, for example vegetation information and hydrographic information are to the work of Heat Island
With very greatly, then can be built to urban construction personnel proposition designated area addition or the more preferable urban planning of reduction vegetation and water body etc.
