无人机三维实景建模技术在矿山地质信息提取中的应用研究

由于科学技术的发展和地质勘查工作的需要,地质找矿工作面临着一定的技术难题,发现在成矿空间内无法准确提取到成矿信息,为了更好地探明矿山深部及外围地质情况,在地质勘查工作中运用无人机三维实景建模技术提取矿山地质信息,建立三维矿山地质模型,可以更加真实的展示矿山的三维空间形态,依照地质学原理,利用无人机三维实景建模技术可以去除无人机航拍图像中的干扰项,实验结果表明,该方法信息提取精度较高,可以为地质找矿及矿产资源动态监测工作提供重要的理论依据。

Research on the application of UAV 3D real scene modeling technology in mining geological information extraction

Due to the development of science and technology and the need of geological exploration,geological exploration faces some technical problems.It is found that the mineralization information cannot be accurately extracted in the metallogenic space.In order to better explore the deep and peripheral geological conditions of the mine,the UAV 3D real scene modeling technology is used to extract the geological information of the mine and establish the 3D geological model of the mine According to the principle of geology,the interference items in the aerial images of UAV can be removed by using the technology of UAV 3D real scene modeling.The experimental results show that the information extraction accuracy of this method is high,and it can provide important theoretical basis for geological prospecting and dynamic monitoring of mineral resources.
