摘　　要：资源三号卫星是中国第一颗自主的民用高分辨率立体测绘卫星,能提供优于5 m地面分辨率的遥感影像。本文首先对资源三号卫星影像预处理过程中涉及的影像纠正、影像配准、影像融合、影像镶嵌等关键步骤进行研究,然后,对比分析三种绿地信息提取方法,最后以江苏省南京市高淳区城市绿地为例,提取建成区绿地信息并加以统计分析。实验表明,本文提出的资源三号卫星影像预处理方法切实可行,国产高分辨率遥感影像适用于城市绿地调查。ZY -3 satellite is the first independent civilian high resolution stereo mapping satellite of China, which can provide better than 5m ground resolution images. In this paper, the key preproccssing techniques such as geometric correction, image registration, image fusion and image mosaic are discussed firstly. Then three green space extraction methods are analyzed in detail and an experi- ment is carried on the Gaochun county of Nanjing city. The experiment results indicate that the pre - processing method is feasible and the domestic high resolution remote sensing image can be used for urban green space extraction.
