摘要
介绍了弱交汇条件下利用PixelGrid系统实现稀少控制点区域的卫星影像的几何纠正方法。阐述了操作流程以及每个步骤的注意事项,对纠正后的影像做出精度检测并给出分析评价。
The paper introduces the research geometric correction of satellite images which have weak convergence and sparse control points Based on PixelGrid System. It expounds the process matters and needing attention on each of steps, checks the quality of corrected images and gives quality evaluation.
