摘要
CBERS-02B HR影像分辨率已接近两米,研究利用该卫星影像进行数字制图具有重要现实意义。本文阐述了该卫星影像的成像方式和特点,在没有严格成像模型的情况下,使用有理函数模型(RFM)对影像进行正射纠正试验,利用控制点解算有理多项式系数(RPCs),能满足1:50,000正射影像图精度的要求。
Since the resolution of CBERS-O2B HR image is close to 2 meters. Therefore, mapping with satellite images should be very useful in practice. This paper depicts this satellite image acquisition method and traits. At the absence of strict imaging model, rational function model (RFM) is used to do ortho rectification, and to solve rational polynomial coefficients (RPCs) by a few control points. The results can welI meet the precision requirement of 1 : 50, 000 ortho images.
