基于多光谱遥感图像,提出了一种集河道主溜线自动检测、河势演变分析、洪水漫滩检测与分析评估功能于一体的黄河洪灾监测系统模型。论文首先对基于遥感图像的主溜线检测、河势演变检测、洪水漫滩检测原理与算法进行了详细描述;然后,利用遥感多光谱图像对所提出的检测算法进行了实验验证,最后对实验结果和系统模型进行了总结和分析。实验结果表明,本文提出的黄河洪灾监测模型具有重要的实用价值。 更多还原

【Abstract】 A flood monitoring system model of Yellow River with multi-spectral remote sensing images is proposed in this paper.This model is a combination of analysis and evaluation functions of automatic main-stream detection,river regime variation analysis,and floodplain detection.In this paper,firstly,the principles and algorithm of the main-stream detection,river regime variation and floodplain based on remote sensing images are described in detail.Then,experiments based on multi-spectral remote sensin... 更多还原
