| 摘 要： | 提出推扫式光学卫星影像系统几何校正产品的3维几何模型的概念,在推导推扫式光学卫星影像系统几何校正产品的3维几何模型基础上,对RPC模型用于表示推扫式光学卫星影像系统几何校正产品的3维几何模型的可行性进行分析,并用SPOT5HRG影像以进行验证。实验表明,RPC模型能够很好地用于表示推扫式光学卫星影像系统几何校正产品的高程起伏引起的变形规律,基于该模型的影像定向精度不低于推扫式光学卫星影像辐射校正产品的严密成像几何模型。

| Abstract: | In general,the systemic geometric correction product of push-broom optical satellite image uses a pure two-dimensional affine transformation geometric model. However,this affine transformation geometric model ignores the deformation caused by uncorrected elevation variation during the geometric correction process. In order to solve that problem,it proposed a conceptual three-dimensional geometric model for systemic geometric correction product. On the basis of deducing three-dimensional geometric model,it a... |
