摘要
QuickBird卫星是目前全世界最高分辨率的商用遥感卫星,通过实验对QuickBird遥感影像平面精度进行验证。实验表明,QuickBird标准影像具有良好的内部几何精度,几何纠正后的影像平面坐标绝对误差精度均方根为0.35m。就单纯单点绝对精度来看,已达到1:2000地形图平面精度要求。
QuickBird is the most high resolution remote sensing satellite in the world, The plane precision of QuickBird's image is validated by experiment. The result shows that QuickBird's image holds high interior geometric precision.In the test the polynomial geometric model is used to rectify remote sensing image. After image rectification,the absolue RMS reaches 0.35 meter. From the point of view of absolute precision of single point, the precision reaches the demand of 1:2000 topographic map's precison.
