基于资源三号卫星遥感影像局部控制纠正精度分析

Based on ZY-3 Remote Sensing Satellite Images of Local Control to Correct Accuracy

资源三号测绘卫星是我国第一颗民用高分辨率三线阵立体的测绘卫星,近年来,农业、灾害、资源环境、公共安全等部门对基于资源三号卫星影像的测绘地理信息服务需求量明显增大。本文通过具体研究试验,利用不同数量平面控制点对分辨率为2 m的资源三号卫星影像进行局部控制纠正,并对纠正后所产生的误差进行对比分析,所得的实验结果对资源三号卫星影像的生产具有一定的指导意义。

ZY-3 satellite is China＇s first civilian high-resolution three-line-array stereo mapping satellite,in recent years,agriculture,disasters,resources and the environment,public safety and other departments demand for mapping geographic information resources and services based on ZY-3 satellite images increased significantly,plane using a different number of control points to 2 m is ZY-3 satellite image corrections,and comparative analysis of the error corrected after correcting the experimental results obtained on production ZY-3 satellite images play a guiding significance.
