CBERS-02C卫星HR正射影像的快速拼接方法

A Fast Mosaicking Method of CBERS-02C Satellite HR Orthophoto

提出了一种适用于CBERS_02C卫星HR相机数据特点的正射影像快速拼接的方法。在以同时相的CBERS_02C全色影像为基准,对HR相机的各子线阵影像(CCD影像)完成精确定向的前提下,能够一步完成HR影像的正射纠正、无缝拼接以及羽化过渡。试验证明,本文方法实用且效率较高,已成功应用于CBERS_02C卫星数据的自动化处理系统。

A method of fast mosaicking orthophoto,applicable to the features of HR camera data of CBERS-02 C satellite,is proposed in this paper. On the premise of taking CBERS-02 C satellite panchromatic images of the same time phase as the standard,as well as accurate orientation of every line array image（CCD image）of HR camera,ortho-rectification,seamless mosaicking and feathering can be accomplished in one step. Experimental results show that the our proposed is feasible and efficient,and has been successfully applied to automatic processing system of CBERS-02 C satellite images.
