摘要
针对资源三号(ZY-3)卫星三线阵传感器特点,利用卫星影像附带的有理函数模型参数(RPC)进行目标定位,检测RPC系统误差,分析4种像面补偿模型的优劣性;详细推导了基于有理函数模型(rational function model,RFM)的ZY-3卫星影像区域网平差模型。以莱州地区ZY-3卫星三线阵影像为例,通过与直接空间前方交会的定位结果相比较,认为该文提出的区域网平差方法在消除ZY-3影像RPC系统误差的同时,大幅度提高了影像的定位精度。
Through integrating three -line arrays sensor characteristics of ZY -3 satellite, using ancillary RPC files to conduct orientation, detecting the system error of RPC, and analyzing the strengths and weaknesses of four adjustable models defined in the domain of image coordinate, the authors deduced in detail the model of block adjustment for ZY - 3 satellite images based on RFM. The ZY - 3 stereo pair in Laizhou was selected to test the proposed method. A comparison with the direct spatial forward intersection shows that the proposed method can not only eliminate the RPC system error of ZY -3 images but also greatly improve the image positioning accuracy.
