Cbers 02 Star Remote Sensing Data Fusion

Multi-sensors Remote Sensing Image Data Fusion is a new method that merge multi-kind or multi-data of remote sensing image data, Using this method, We can get multi-data of Redundancy,Complement,Cooperation;Can need to provide in the time resolution, the spatial resolution, the spectrum resolution request different multiple source fusion data according to the different application.This article in view ofCBERS-02B satellite CCD, HR data, take picture element level image fusion as research key, mainly has completed the following work:(1) Summarizes in the domestic and foreign remote sensing image fusion research present situation, has obtained the present stage remote sensing image fusion important question is: Lacks the unification the data fusion model, therefore causes its scope to be narrow, appears quite difficult in the fusion pattern-shop interconversion, therefore summarizes the commonly used remote sensing image fusion model to summarize its general character and the difference is one of remote sensing image fusion subject matters.(2) General introduction remote sensing image fusion's three levels, based on the picture element level, the characteristic level, the policy-making level fusion's respective characteristic and the definition, and have based on this studied and act according to the respective fusion model based on the picture element level image fusion commonly used method based on the picture element level fusion from three aspects: The algebra fusion, the transformation territory fusion, the tower system decomposition and the reconstruction fusion have conducted the research and the summary.(3) Summarized based on the characteristic statistics, with information content some theories, and uses them in the image fusion result appraisal, proposed based on the different goal choice different evaluation criteria's target, the experimental result proves these theories to be able the very good reflection fusion image quality.(4) Based on CBERS-02B satellite CCD, the HR remote sensing data, and developed the platform using IDL the commonly used algebra operational method, to fluctuate the territory fusion law, the theoretical model to carry on the integration, the experimental result proved that this can quickly more accurate the data which will obtain needs.Using platform which develops, with the CBERS-02B CCD, HR data, the experiment had proven based on the picture element level fusion's multiple source remote sensing image fusion, can obtain has the redundancy, the complementarily, the cooperative multiple source data, thus is the CBERS-02 satellite at the geological disaster, aspect and so on agricultural production applications provide a more accurate data.
