摘　　要：为了提高地表覆盖物质测绘信息的准确性,在遥感影像处理技术的基础上,研究了一种地表覆盖信息的提取技术。采集机载遥感影像地表特征信息,初步处理数据,配准采集的影像,统一坐标与计量单位,进行融合处理,增强影像信息的清晰度与鲜明度,采用灰度调整法去除影响噪声,实现地表覆盖信息的提取。试验结果显示,该方法对地表覆盖信息的采集图斑的数量和正确率均优于传统方法。In order to improve the accuracy of mapping information of surface covering materials,based on the image processing technology of remote sensing images,an extraction technology of surface covering information was studied.Collect the surface feature information of airborne remote sensing images,preliminarily process the data,register the collected images,unify the coordinates and measurement units,carry out fusion processing,enhance the clarity and vividness of the image information,and use gray adjustment method to remove the influence noise,so as to realize the extraction of the surface coverage information.The experimental results show that this method is superior to the traditional method in the number and accuracy of land cover information collection.
