【摘要】:文中首先介紹了World View3的影像組織形式、和其他遙感影像的影像質(zhì)量對比情況,研究了時點核準(zhǔn)影像生產(chǎn)流程、精度統(tǒng)計、時點核準(zhǔn)數(shù)據(jù)采集。從整個試驗區(qū)中可看出World View3影像成像近似模型中RPC參數(shù)的精確度很高,無控與有控糾正模式對影像的精度影響不大。利用影像成果對時點核準(zhǔn)時變更的地物進行修改,可保證地理國情普查數(shù)據(jù)更加精確反映現(xiàn)實的地理國情,同時也可參照影像成果對前期的地表覆蓋與地理數(shù)據(jù)進行核實檢查,從而更為精確的定性和定位。
[Abstract]:This paper first introduces the image organization form of World View3, and compares the image quality with other remote sensing images, and studies the production process and precision statistics of the time-approved image. From the whole experimental area, we can see that the accuracy of RPC parameters in the approximate model of World View3 imaging is very high. The model of no control and controlled correction has little effect on the accuracy of the image. Using the image results to modify the objects changed when the time points are approved can ensure that the census data of geographical conditions more accurately reflect the actual geographical conditions. At the same time, the surface coverage and geographic data can be verified and checked with reference to the image results, so that the qualitative and location can be more accurate.
