一种卫星遥感影像村庄区域提取算法

摘要

卫星遥感影像提取村庄区域在地理和气象领域均有十分重要的意义.针对卫星遥感影像的特点,提出了一种村庄区域提取方法.利用改进的去雾算法对卫星遥感影像进行预处理,通过遥感卫星影像的颜色特征实现分割,结合村庄区域分布特点进行去噪处理,实现卫星遥感影像村庄区域的提取.实验结果表明:该算法能够对卫星遥感图像中不同类型村庄区域进行提取,且提取准确率高,可以应用于地理以及气象等领域.%It has important significance to extract village area in satellite remote sensing image in the field of geography and meteorology.Aiming at characteristics of satellite remote sensing image,a new method for extraction of village area is proposed.Preprocess satellite remote sensing images using improved defogging algorithm,segmentation is achieved by color feature of remote sensing satellite image,denoising is carried out combined with the characteristics of regional distribution of the village,extraction of village area in satellite remote sensing images is realized.Experimental results show that this algorithm can be used to extract different types of villages in the remote sensing image,the extraction accuracy is high,and it can be applied to the geographical and meteorological fields.
