摘要: 基于高分一号(GF-1)多光谱数据研究提出了一种平原地区农村居民点自动化提取方法。该方法充分挖掘利用光谱信息,计算特征影像与新的相似性特征空间。据此,使用分类和阈值分割思想提取居民点初选区域,并避免了传统分类方法在快速自动化提取过程中的不足以及阈值分割造成的影像细节信息的丢失。通过研究选取合适的结构元素对居民点初选区域进行有目的、可控的形态学处理,最终达到农村居民点自动化快速提取的目的。实验结果表明:该方法提取精度良好,总体精度达到86.9%,自动化提取速度快,在农村居民点提取、城镇化规划与建设等研究中有较高实际应用价值。 关键词: 高分辨率;  农村居民点;  自动化;  快速提取;  遥感     Abstract: An automated extraction method was proposed for rural resident in plain area in this study based on GF\|1 multi\|spectral Remote Sensing image.The study makes full use of multi-spectral information to calculate feature image which can highlight certain classes,and then establish new similarity feature space.Accordingly,we use the idea of traditional classification and Thresholding to extract primary selected resident area,but avoid the shortcoming of traditional classification in the process of fast automatic extraction and avoid lost image details caused by Thresholding.By studying how to select apposite structural elements,we could carry out purposeful and controllable morphological processing\|filling the internal holes of primary selected resident area,and then expend the whole area by using these structural elements\|to get the rural resident extraction mask.At last,using mask extraction and NDVI Thresholding method get the final result.Experimental results show that the method has high extraction accuracy,the overall accuracy of 86.9%,and high extraction speed,which is very useful to rural resident extraction and town planning and construction.
