基于1∶1万DEM的SPOT5遥感影像正射纠正

Ortho-rectification of Spot5 Remote Sensing Image Based on the 1∶10000 DEM

论述了在山地大高差情况下,选用遥感影像校正模型、点位纠正与配准进行质量控制和精度分析,对数据处理重采样、分辨率融合,以多景影像数字镶嵌方式进行SPOT5遥感影像正射纠正的方法。精度分析结果表明,采用物理纠正模型对地形起伏较大的地区进行正射纠正可以取得较好的结果。

On the condition of great height difference in mountainous region, the remote sensing image rectification model, point position rectification and geometric registration were used to ensure the quality and precision. The methods of data processing, resampling, resolution fusion, digital mosaic of multiscenes remote sensed images were studied. The precision analysis showed that the good result could be gotten by using the physical rectification model to ortho-rectificate the great height difference district.
