矿区3维可视化及其应用

3维可视化是当前数字矿山理论及其技术研究领域的关键问题之一。以云南澜沧老厂为研究区,将高精度数字高程模型(DEM)数据与矿区高分辨率2维遥感图像(QuickBird影像)叠合生成3维遥感影像,能够真实再现老厂矿区的景观特征,有效反映该地区的复杂地形、地貌、地质特征,提供综合、全面、实时、动态的矿山地面变化信息,为矿床定位及开展地质工作服务。

Mining Area 3D Visualization and its Application

3D visualization is one of the key questions in the current digital mine theory and its technology domain.Taking the Laochang mining area of Lancang District in Yunnan province as the research area,it produces the 3D remote sensing image using the high accuracy digital elevation model(DEM) and high resolution 2D remote sensing image of the mining area.The 3D image can really represent the landscape characteristic of Laochang mining area,and effectively reflect the complex terrain,landform,and geological characteristic of the area.It provides the comprehensive,real-time,and dynamic mine ground change information,which serves for the positioning of ore deposit as well as the developing geology work.
