Carry out deviation revision.
In embodiments of the present invention, the purpose of revision is to carry out data sieve to picture information and binaryzation data
Choosing.Above-mentioned default observation condition is that data format meets observation format, and climate state is without departing from preset climate state range,
Also to meet horizontal and vertical continuity requirement, and be located within assimilation time window.It is not met in rejecting observational data default
When the data of observation condition, Data selection is carried out to original weather station observational data and moonscope data, when filtering out assimilation
Between Shock absorption effect in window, the method step includes: climate state extreme value range validity check, from observation data
It is middle to reject the abnormal point deviateed other than Climatological pre-determined distance;Format and logical check reject in observational data and illegally observe lattice
Formula data reject missing point present in observational data;Horizontal and vertical continuity check will not be met continuous in observational data
Property require point deletion;The not data in assimilation time window in observational data is rejected in time consistency inspection, specifically used
Image processing algorithm can be according to actual conditions depending on, which is not limited by the present invention.
Step S102 is obtained next using preset extension model using the initial fields as input carry out data extension
The extension observational data at moment;

Gas neural network model exports the highest integrated data of accuracy, it may be said that the network state valence of the atmosphere neural network model
Value is maximum;Extend the state estimation that model is used to save the classification image document of each rank.Extend model and passes through a depth
A neural network for spending neural network classification (a certain rank) image, by certain strategy come percentage regulation neural network
Weight coefficient, the best estimate of (a certain rank) image is classified, as classification (certain level-one under a certain resolution ratio
Clear image not).Deep neural network describes the state of atmosphere using full connection type, is adjusted by weight and bias
Weight, extension obtain the image under a certain rank.
Step S303 synthesizes extension data corresponding to N number of rank, reconstructs the extension observation money of subsequent time
Material.
The embodiment of the present invention is worked as by the way that original observed image data is divided into N number of rank according to image attributes first
Then classification image document corresponding to preceding moment each rank utilizes institute of the preset deep neural network based on each rank
It states classification image document to be extended, obtains extension data corresponding to each rank of subsequent time, it finally can be to N number of rank
Corresponding extension data carries out image synthesis, reconstructs the extension observed image data of subsequent time.Extended model can be with
It is atmospheric depth neural network, such as: the embodiment of the present invention can be using deep neural network based on described in each rank points
Grade image document is extended, and extension data corresponding to each rank of subsequent time is obtained, due to the deep neural network
Using the weight coefficient of preset tactful neural network output as input, the weight coefficient can make the deep neural network
Network state Maximum Value, the embodiment of the present invention can using make deep neural network network state Maximum Value weight
Coefficient configurable deep neural network, and provided using extending to obtain the extension under residual error minimum with the deep neural network postponed
Material is based ultimately upon the extension observed image data that extension data reconstructs subsequent time, improves and extends accuracy.Based on step
S301, the embodiment of the invention also provides a kind of feasible patterns, and initial fields are divided into N number of rank according to image attributes, are worked as
Ranked data corresponding to preceding moment each rank, comprising: obtain initial fields;The initial fields are subjected to Wavelet image decomposition,
Obtain ranked data corresponding to current time each rank.
Wherein, Wavelet image decomposition method can provide the small echo classification image of different resolution or different scale, will divide
The small echo of different resolution or different scale after solution is classified image, the different stage image after decomposing as Wavelet image.
Correspondingly, it is based on step S303, and it is described that extension data corresponding to N number of rank is synthesized, it reconstructs next
The extension observational data at moment, comprising: extension data corresponding to N number of rank is synthesized using wavelet inverse transformation, is reconstructed
The extension observational data of subsequent time out.
In this step, can use the inverse transformations such as wavelet inverse transformation mode to extension data corresponding to N number of rank into
The synthesis of row image, reconstructs the extension observed image data of subsequent time, the extension observed image data of subsequent time can be with structure
At a clear image.
Step S103, it is integrated using the extension observational data as input carry out data using preset integrated model, it obtains
To integrated data.
In embodiments of the present invention, it is input in preset integrated model by the way that observational data will be extended, instead of traditional
Single integrated approach, a variety of extensions observation money is integrated, and pass through the multi-mode weight proportion function of integrated model, final
