城市高分辨率卫星影像几何校正技术研究

Research on Geometric Correction Technology of Urban High-resolution Satellite Image

高分辨率卫星遥感影像对于城市智能感知、土地资源监测管控具有重要作用。影像的几何精度是影像应用效果的重要保障,如何高效地对影像进行精确的几何校正是如今遥感应用的重要研究内容。文章面向城市遥感应用需求,探讨了一种利用正射纠正影像作为参考,利用城市地物特征点自动匹配完成影像配准,最终实现高分辨率卫星遥感影像几何校正的方法。

High-resolution satellite remote sensing image plays an important role in urban intelligent perception and land resource monitoring and control. Geometric precision of image is an important guarantee of image application effect. How to carry out accurate geometric correction of image efficiently is an important research content of remote sensing application nowadays. Aiming at the application demand of urban remote sensing, this paper discusses a method to finally achieve geometric correction of high-resolution satellite remote sensing image by using orthographic correction image as a reference, and automatically matching of urban feature points to complete image registration.
