基于轻小型无人机的离子吸附型稀土矿山开发状况遥感调查方法

Application of Remote Sensing Investigation Technology of Unmanned Aerial Vehicle in Ion-adsorbed Type Rare Earth Mines

近年来稀土矿山无序开采、乱采滥挖现象比较严重。依据稀土矿山的开采方式,利用无人机遥感机动性强,受天气影响小,数据分辨率高等特点。通过飞行作业和数据处理来获取调查区域的完整影像,并利用面向对象方法开展信息提取和分析,能够查明离子吸附型稀土矿山开发状况,更加精确掌握区内采矿活动真实状况。该方法能进一步丰富稀土矿山遥感调查手段,提升调查时效性和精准度。

In recent years, the disorderly and indiscriminate mining of rare earth mines is quite serious. The unmanned aerial vehicle(UAV) remote sensing is used to identify the developing status of ion-adsorbed rare earth mines, and we can get the real situation of mining activities more accurately. It generally includes flight operations and data processing, through which the complete image of the survey area is obtained, and extracting information and analysis are conducted by the object-oriented classification. This method can further enrich the remote sensing survey ways of rare earth mines and improve the timeliness and accuracy of the survey.
