基于Erdas9.2的QuickBird影像的正射校正

Ortho-rectification of QuickBird Image Based on Erdas9.2

为了提高数字正射影像图(DOM)的几何精度,以便为土地调查、土地变更、土地监测等工作提供准确的信息。在土地利用遥感监测工作实践的基础上,探讨总结了应用Erdas9.2对QuickBird数据进行正射校正的方法、步骤和校正工作中应注意的技术难点。实践表明,采用Erdas软件校正QuickBird影像,其效果是十分理想的。

In order to improve the geometric accuracy of DOM, to provide accurate information on the work ofland survey, land change, land monitoring. On the practice of remote sensing monitoring of land use, the author summarized the geometric correction method, procedure and the technical difficulties during rectification of QuickBird by using Erdas9.2. This study had shown that using Erdas software to rectify QuickBird image was ideal.
