结合ZY-1 02C卫星高分辨率(HR)相机的成像特点,深入分析了各种潜在的误差来源,提出了一种基于虚拟线阵的非共线TDI CCD相机成像数据内视场拼接方法,采用ZY-1 02C卫星HR相机获取的影像数据进行了拼接实验。通过对拼接结果的定性和定量评价,验证了该方法的正确性和可行性。目前该方法已成功应用于ZY-1 02C卫星数据处理的业务化运行系统中。
Considering the imaging features for High Resolution(HR)camera of ZY-1 02 Csatellite,this paper proposes an inner Field of View(FOV)stitching method based on virtual CCD line.Then,the potential error sources of the method are analyzed deeply.Finally,image data of ZY-1 02C/HR camera are used in experiments.Both qualitative and quantitative evaluations on results validate the correctness and feasibility of the method.At present,the presented method has been embedded in the daily processing system of ZY-1 02 Csuccessfully.
