摘　　要：利用数字高程模型(DEM)模拟具有正立体视觉效果的人工光源图像;通过数据融合处理地质图和人工光源图像,生成视立体地质图。这种新型地质图不仅具有原地质图的完整地质信息,还具有直观的地形地貌特征,立体感强;同时,数字视立体地质图具有地理编码信息,在通用图像处理软件支持下,可以确定图上任意位置的地理坐标,便于野外地质调查、地理定位及图面测量等工作,具有很高的实用价值。Firstly, an artificial light source image was simulated by digital elevation model DEM; then, an apparent 3 D geological map was prepared by the data fusion of the geological map and the artificial light source image. This new type of geological map has not only the complete geological information of the geological map but also the intuitive features of the terrain, with some three - dimensional effect. At the same time, the digital apparent 3 D geological map with geo - coding information can be used to determine the geographic coordinates of any position on the map. This map is potentially useful in such aspects of the field work as geological investigation, positioning and mapping, thus having a very high practical value.
