基于高分辨率Quick Bird影像的数字正射影像图的制作

Production of Digital Orthophoto Map Based on High Resolution Quick Bird Remote Sensing Image

与线划图相比,遥感影像正射图有很多线划图无法比拟的优点,因此它在城市规划、土地管理、铁路、公路选线等方面有着特殊的应用。以某市Qu ick B ird遥感数据为例,介绍了从原始卫星影像图的收集到在ERDAS遥感图像处理软件中进行遥感影像正射图制作的方法和步骤。描述了正射影像图制作中的融合、纠正等的流程及原理。实践证明遥感卫星数据时效性好、覆盖范围大、成本相对低廉。因此利用商业化的遥感图像处理软件直接对遥感卫星图像产品进行正射纠正,继而制作系列正射影像图,是一条效果良好的技术路线。

Digital orthophoto map has many advantages compared to digital line graphic. The digital orthophoto map is broad applied in urban planning, land use management and route planning of railway and highway. This paper mainly described the process and mechanism of rectification and data fusion during the production of orthophoto map. It is proved that the remote sensing satellite data is timely, widely covered and costs relatively lower. It is an effective route to rectify remote sensing data and produce digital orthophoto map based on commercial remote sensing software.
