摘　　要：平面遥感通过阴影体现立体感,其立体效果一般较差;卫星三维遥感通过DEM体现立体感,有较好的立体效果,但由于卫星平台太高,难以体现较小的地形起伏,而且陡坎处影像容易出现拉伸变形;无人机三维遥感立体效果最好,由于获取影像的平台较低,细微的地形起伏均可以较好地反映。本文针对传统方法在构造解译上的不足,利用无人机获取岩溶隧址区遥感数据建立三维遥感影像模型,进行岩溶构造解译,并与传统构造解译方法做了对比。结果表明,无人机三维遥感解译可以大大提高隧址区岩溶构造解译的精度和可信度,可为岩溶地区的隧道施工提供准确基础资料。Plane remote sensing reflects the three-dimensional effect through the shadow,and its stereoscopic effect is generally poor.The satellite three-dimensional remote sensing reflects the three-dimensional effect through DEM and has a good three-dimensional effect.Since the satellite platform is too high,it is difficult to reflect the small terrain fluctuations and the steep slope,and the image is prone to tensile deformation.The three-dimensional remote sensing effect of UAV is the best,and the fine terrain fluctuation can be better reflected due to the lower platform for acquiring images.In view of the shortcomings of traditional methods in structural interpretation,this paper uses UAV to obtain remote sensing data of karst tunnel area to establish a three-dimensional remote sensing image model,interprets the lava structure,and compares it with the traditional structure interpretation method.The results show that the three-dimensional remote sensing interpretation of UAV can greatly improve the accuracy and credibility of interpretation of karst structure in the tunnel area,and provides accurate basic data for tunnel construction in karst areas.
