Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments of the present invention, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention discloses an atmosphere monitoring sailing method based on a backward track model and a remote sensing image by an embodiment, and has the innovation points that the idea of an airbus pixel factory is absorbed, the remote sensing image is automatically subjected to primary processing, and a large amount of labor is saved. The full automation of the operations of geographic registration, radiation correction, FLAASH atmospheric correction, orthographic correction, sharpening and the like is realized. Meanwhile, the system can also automatically extract various indexes and automatically draw polluted areas. The remote sensing image comprises but is not limited to a high-resolution satellite series developed independently in China, a high-view/Beijing satellite series, a hyperspectral (such as high resolution 5/Oldhatt and the like) satellite series, a resource satellite series, a wind and cloud satellite series, a foreign Landsat satellite series and radar satellites in various countries, and the data of the satellites are used for calculating indexes such as surface temperature, surface humidity, leaf area index, vegetation coverage, net primary productivity and the like of local areas. These indices provide precision support for the following backward trajectory module.
The method comprises the following steps:
q1, preprocessing data, automatically extracting aerosol wave bands in a monitoring area according to remote sensing image data, independently performing radiation correction on the aerosol wave bands, independently extracting after atmospheric correction, starting a preprocessing program, and independently performing research and analysis on a pollution area (for example, a system finds that the aerosol thickness in a certain area has an obvious rising trend or reaches an alarm critical line, and automatically buffers and masks the area, and the masked area is determined as a research area. the traditional method adopts manual intervention and needs a large amount of background personnel. the method refers to the idea of airbus pixel factory, completely breaks away from manual work, although the parameters such as color and hue of an effect picture are not beautiful, but are completely enough when a computer reads the result), and in the research and analysis result, if pollutants in the pollution area are found to be obviously improved compared with the previous date, the pollution research range data is provided, sending the report to a backward track model module to generate a corresponding (. txt format) log file for auditing; the aerosol wave band comes from a multispectral and hyperspectral remote sensing satellite with the aerosol wave band, and remote sensing image data are remote sensing images after geographic registration, radiation correction, FLAASH atmospheric correction, orthographic correction and fusion by using GIS base map products above L2.
The radiometric calibration may calibrate the values of the telemetry data to radiometric and reflectivity. This option can be used if the image has gain and offset for each band. The calculation formula of the radiation is as follows:
Lλ=Gain*Pixel value+Offset
if the gain and offset are in W/(m2 sr μm), the radiation dose is also in W/(m2 sr μm)
Atmospheric Top (TOA) reflectance (0 to 1.0). This option may be used if the image has gain, offset, solar irradiance, solar altitude, and acquisition time defined in the metadata.
If the input file contains metadata about the reflectivity gain and offset, the algorithm will use these values to calibrate the data to TOA reflectivity. The algorithm measures the reflection gain and offset from the sine of the solar altitude, for example using the Landsat-8 file. If the input file does not contain metadata about the reflectivity gain and offset, the algorithm will calculate the TOA reflectivity using the following formula:
wherein:
Lλradiance in units of W/(m2 sr μm)
d is the earth-sun distance in astronomical units.
ESUNλSolar irradiance, in units of W/(m2 ×)μm)
Theta is the sun altitude angle
Radiance this option is only applicable to terrestrial satellite-8, ETM + and TM thermography. The luminance temperature (kelvin) is calculated as follows:
wherein:
k1 and K2 ═ calibration constants (kelvin). The algorithm reads these values from the metadata of Landsat.
Atmospheric correction: spectral hypercube fast line-of-sight atmospheric analysis (FLAASH) is an atmospheric correction module developed by the Spectral Sciences institute (Spectral Sciences Inc.) with the support of the united states air Force Research Laboratory.
FLAASH is an atmospheric correction method that retrieves spectral reflectance from hyperspectral radiometric images. FLAASH employs a modern radiation transfer model to compensate for atmospheric effects. The method has the advantages of high precision and long calculation time compared with other algorithms (such as QUAC). FLAASH is integrated into my algorithm.
