基于无人机遥感拍摄的稀土矿检测研究

摘要

The unique characteristics of rare earth elements have the effect of absorbing shortwave in infrared spectrum.As a resource-rich country in rare earth,how to effectively recover the rare earth resources has become important for the state to effectively utilize the rare earth resources.The UAV is used to estimate the volume and resources of mineral resources by using various types of sensor devices(photogrammetry equipment,laser radar,SAR imaging radar,portable XRF,etc.).Taking neodymium as the research object,we have known about the content of the element,including the spectral absorption depth in the area.It is proved that the absorption characteristics of rare earth elements can be identified in high-quality,no-load and hyperspectral data sets.The detection of rare earth mineral resources can be accomplished by deploying hyperspectral instruments.%稀土元素所特有的特征对于短波红外光谱具有吸收的效果,我国作为一个稀土资源丰富的国家,如何对稀土矿资源有效回收成为国家有效利用稀土资源的重要手段.采用无人机搭载各型传感器设备(摄影测量设备、激光雷达、SAR成像雷达、便携式XRF等)对矿产体积及资源进行估计;以钕元素作为研究对象,主要对该元素的含量与光谱吸收的深度和面积的关系进行了研究,证明在高质量、空载、高光谱数据集上能够识别稀土元素的吸收特征,并以无人机部署高光谱仪器可完成对稀土矿产资源的检测.
