摘要
提出遥感图像地质解译三维可视化及影像动态分析新方法,综合利用3S技术、遥感图像数字处理技术、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、多类型遥感图像数据融合、高精度DEM生成和影像复合等工序,按照一定比例尺和飞行路线生成测区的虚拟三维影像动画系列图,以解决高原区数字区调工作者面临的实际问题,弥补其不足。
The paper brings forward a new method-3D visualization of geo lo gical interpretation of remote sensing images and image dynamical analysis for the regional geological survey,which integrates the roles of advanced technol ogies including'3S'(RS ,GIS and GPS)techniques,remote sensing image digit al pro-cessing,virtual reality and digital photographic measuration technique and so on.Based on this method,3D virtual images are created according to cer tain scales and fight routes.The method commendably solves practical problems for digital regional geological survey in altiplano and makes up for some de ficiency in the traditional regional geo-survey by a series of working procedu res such as RS orthophoto processing,data fusion of multi-types RS images, high precision DEM building and image synthesizing.
