缺少控制点的SPOT-5 HRS影像RPC模型区域网平差

SPOT-5 HRS Satellite Imagery Block Adjustment Without GCPS or with Single GCP

摘要: 从卫星遥感影像区域网平差的模型出发,利用SPOT-5影像附带的参数拟合RPC模型参数,根据RPC模型和像面的仿射变换模型建立了卫星遥感影像区域网平差的数学模型。按照所构建的数学模型,对两个地区SPOT-5 HRS影像进行直接空间前方交会和缺少控制点的区域网平差处理。试验证明了本文模型的可行性。

Abstract: Tie paper developed the satellite imagery block adjustment.Testing the satellite imagery block adjustment on SPOT-5 HRS imagery in two areas without any GCP,on condition of one strip,the mapping accuracy matches the criteria of 1∶500 000.on condition of two stripes,the accuracy matches the criteria of 1∶50 000;Then testing the satellite imagery block adjustment on SPOT-5 HRS one strip imagery without single GCP,the mapping accuracy matches the criteria of 1:50 000.Thus,the validity of the transformation in image plane plus RPC model has been verified.The results show the potential of using this model for mapping terrain with satellite imagery.
