三维遥感在西藏狮泉河地区地质解译中的应用

The application of three-dimensional remote sensing in geological interpretation of Shiquan river region in Tibet

综合利用3S技术、遥感图像数字化处理技术、虚拟现实和全数字摄影测量等高科技,通过遥感图像的正射影像处理、多类型遥感图像融合、高精度DEM生成和影像复合等工序生成的遥感三维影像具有真实、客观、生动、信息连续、宏观观测等诸多优势。本文以西藏狮泉河电站地区为例,通过不同地层不同岩性所具有的特性及分布状况的研究,对西藏狮泉河地区地层、断层规模、性质、断面产状等信息进行遥感地质解译,以解决在实际工作中西藏高海拔地区人迹难至的难题。

Comprehensive use of 3S technologies,remote sensing image digital processing technology,virtual reality and all-digital photogrammetry and other high technologies,The remote sensing 3D images generated by remote sensing images,multi-type remote sensing image fusion,high-precision DEM generation and image composite processes have many advantages such as true,objective,vivid,continuous information,and macroscopic observations.Taking the Shiquanhe Hydropower Station in Tibet as an example,this paper uses the characteristics and distribution of different lithologies in different strata to carry out remote geological interpretation of the stratum,fault size,nature,and section appearance in Tibet Shiquanhe region.To solve the hard-to-reach problems in high altitude areas in Tibet in practical work.
