摘　　要：无人机遥感系统可以获取矿区高分辨率遥感影像,具有较强的灵活性和现势性,成图速度快,能广泛应用于各种调查任务。本文以江西省定南县稀土矿区为研究区,介绍了无人机遥感系统的组成、航拍流程和数据处理的方法,通过面向对象的多尺度分割技术,建立不同地物类别对应的分类层次,然后根据地物特征进行信息提取,最后总结出一套基于无人机遥感的矿产信息提取方法。UAV remote sensing system can obtain high-resolution remote sensing image of mining area,with strong flexibility and current situation,with mapping speed. It can be widely used in various survey tasks. In this paper,the rare earth mining area of Dingnan County in Jiangxi Province is taken as the research area. It describes the composition of UAV remote sensing systems,aerial processes and the method of data processing. Through the object-oriented multi-scale segmentation technique,creating different classification levels of the different feature classes,,and finally summarize a set of extraction methods of mineral information based on UAV remote sensing.
