摘要
研究在少量地面控制点情况下,利用仿射变换模型、多项式模型、有理函数模型对资源三号卫星(ZY-3)正视影像进行几何纠正。在无控制点参与精度评估情况下,提出利用几何纠正图与地形图叠合显示的方法评估几何纠正精度。研究表明:在少量分布合理的地面控制点下利用有理函数模型对ZY-3进行几何纠正,其几何纠正精度能达到后续应用的需求,具有一定的理论意义与实际应用价值。
It uses the affine transform model,polynomial model,and rational function model for geometric correction for ZY-3's front view image in the case of a small amount of ground control points.Under the condition of no control points in precision evaluation,a method of using the corrected images with the topographic map composite shows is used to assess the precision.The study shows that under the condition of rational distribution of a small amount of ground control points,the result of using rational function model for ZY-3's image can meet the demand of subsequent application.And the research has certain theoretical significance and practical application value.
