Description
Technical field
A kind of the present invention relates to Remote Sensing Image Processing Technology field, in particular it relates to MODIS image datas disappearance reparation side
Method.
Background technology
IDEA-I is that international MODIS/AIRS satellite datas process bag project (International MODIS/AIRS
Processing Package, IMAPP) sub-project for undertaking Air Quality Forecast in project.The polluter of IDEA-I models
(Aerosol Optical Depth, AOD) data that data are obtained essentially from satellite remote sensing.
But the aerosol optical depth image data of MODIS is often lacked, affected by weather larger, in sleet, cloudy
Under etc. weather condition, where being covered by sleet, cloud etc., it is more likely that be without value region, substantial amounts of cause to enter without value area
Row Air Quality Forecast.
In sum, present inventor has found above-mentioned technology extremely during the present application technical scheme is realized
There is following technical problem less:
There is MODIS images and there is disappearance in Air Quality Forecast method of the prior art, occur, without value region, causing nothing
Method is normally carried out the technical problem of Air Quality Forecast.
Content of the invention
The invention provides a kind of MODIS image datas lack restorative procedure, air quality of the prior art is solved
There is MODIS images and there is disappearance in Forecasting Methodology, occur, without value region, leading to not the technology for being normally carried out Air Quality Forecast
Problem, it is achieved that when MODIS image deletions, image data can be repaired, can accurately carry out Air Quality Forecast
Technique effect.
In recent years, ground air monitoring station website is more and more, and the area of covering is also increasingly wider, its data stabilization,
Reliable, continuous, a secondary data can be obtained per hour, and the data type for including is abundant (including PM2.5, PM10, AQI etc.),
Can be very good the supplement as remote sensing image data.Therefore, using ground air monitoring station data write MODIS images come mould
Plan is a kind of method of MODIS image datas disappearance in feasible solution IDEA-I locus models.
This application provides a kind of MODIS image datas lack restorative procedure, methods described includes:
S1:The shooting time t of MODIS images is obtained, the real-time of the time point air ground monitoring station is obtained according to time t
AQI values;
S2:Latitude and longitude coordinates information using ground monitoring station website mating remote sensing image picture element, by ground monitoring number
According to being added in remote sensing image;
S3:To having added the remote sensing image after ground monitoring data, during the method for utilization space interpolation is to remote sensing image
Enter row interpolation reparation without value region.
Without value accuracy of the regional effect IDWA-I locus models to Air Quality Forecast, and according to remote sensing image number itself
According to and the ground monitoring station data that adds do space interpolation, can finally obtain that a width is smooth and there is the distant of value in all regions
Sense image.
Wherein, air quality index (Air Quality Index, abbreviation AQI).
Further, step S2 is specifically included:
Based on the coordinate information of each pixel in remote sensing image, judge ground monitoring station website latitude and longitude coordinates (lon,
Lat) whether the value of corresponding pixel lacks;If the corresponding pixel of the latitude and longitude coordinates (lon, lat) has value, then execute S201;If should
The value disappearance of the corresponding pixel of latitude and longitude coordinates (lon, lat), then execute S202;
Wherein, S201:Do not deal with, continue the next monitoring station of coupling, until having mated all of ground monitoring station
Point;
S202:AQI values are converted to AOD values and write remote sensing image.
Air quality index is changed with aerosol optical depth (AQI and AOD), through existing numerous studies and experiment,
There is dependency between AQI and AOD, research on utilization achievement, by conversion formula, the AQI that will can be obtained from ground monitoring station
Value is converted into AOD values.After by conversion AOD values write remote sensing image in, then proceed to mate next monitoring station, until
All of ground monitoring website is matched somebody with somebody.
Further, enter row interpolation reparation without value region during the method for the utilization space interpolation is to remote sensing image, have
Body includes:Use anti-distance weighting interpolation method (IDW), its basic thought is two object similaritys with the distance between them
Increase and reduce.Distance between interpolation point and sample point for weight be weighted averagely, from interpolation point more close to sample give
Weight is bigger.By anti-distance weighting interpolation method (IDW) with the ground monitoring station data of remote sensing image data itself and interpolation
To enter row interpolation to remaining without value region, the complete remote sensing image of a width can have finally been obtained.
Further, described AQI values are converted to AOD values and write remote sensing image, specifically include:AQI data are high, represent
Atmospheric turbidity is higher, directly influences the value of AOD.AQI data and AOD data from physical significance for general keep positive
The relation of closing property.Method more common at present is, in the same area, under conditions of weather conditions are approximate, individually set up and returns
One changes equation:
AQI=η × AOD (1)
η is to affect moonscope environment AOD factor action functions, relevant with humiture and aerosol vertical extinction degree.
Further, the real-time AQI values for obtaining the time point air ground monitoring station according to time t, specially:In
Data center of magnificent Chinese Ministry of Environmental Protection of people's republic (http://datacenter.mep.gov.cn/) can in real time update the whole nation each
The pollutant monitoring data of monitoring station, and primary pollutant is announced, provide air pollution index.By the data reptile of webpage
Technology by these data storages to data base, by the anti-function of looking into of Baidu map API geographical coordinate, you can obtain band longitude and latitude
The AQI data of coordinate.
In IDEA-I locus models in the application, the method for MODIS image deletion reparations is specially:Insertion air ground
Monitoring station data, add the method for space interpolation to simulate MODIS images, so that when MODIS image deletions
Air Quality Forecast can be done.
One or more technical schemes that the application is provided, at least have the following technical effect that or advantage:
The method that MODIS image deletions are repaired in the IDEA-I locus models of the present invention, according to during the shooting of remote sensing image
Between t, using latitude and longitude coordinates (lon, lat) the information matches remote sensing image corresponding coordinate point of ground monitoring website, judge remote sensing
In image, whether same coordinate points have value, then do not deal with if there are value, continue the next ground monitoring website of coupling;If nothing
Value, then air quality index (AQI) data for monitoring ground monitoring website are converted to aerosol optical according to conversion formula
Then AOD values are write remote sensing images, then mate next ground monitoring website, until all of website by thickness value (AOD)
With completing, after the completion of all ground monitoring station data couplings, then carried out without value region to remaining with the method for space interpolation
Interpolation, finally obtaining all regions of a width has the remote sensing image of value, so, efficiently solve air quality of the prior art
There is MODIS images and there is disappearance in Forecasting Methodology, occur, without value region, leading to not the technology for being normally carried out Air Quality Forecast
Problem, and then achieve when MODIS image deletions, image data can be repaired, can accurately carry out air quality
The technique effect of prediction.
