摘要
断裂构造解译为探测矿藏及其分布提供指引,同时也可以反演相关的地震活动。针对断裂构造实地调查效率低下的缺点,由获取的机载LiDAR点云数据构建DEM,使用DEM晕渲和DEM定向滤波结合的方法研究断裂构造的解译标志和规程,最后通过人机交互解译断裂构造。经与获取的地质资料对比,证明其正确性。试验表明:以机载LiDAR技术为支持,人机交互解译断裂构造是可行的、高效的。
Interpretation of fault structure provides guidelines for locating mineral deposits and their distribution,meanwhile,it is related to the interpretation of seismic activity.Aiming at the low efficiency of fault structure,the paper generates the DEM based on airborne LiDAR point cloud data,then,the method of combining DEM hill shading and DEM directional filtering is given to study the interpretation symbols and rules of the fault structure.Thereafter,this paper interprets a fault structure through humancomputer interaction.Compared with the available geological information,it proves correct.The test shows that,with the support of the airborne LiDAR technology,it is feasible and efficient to interpret the fault structure using the method of human-computer interaction.
