摘　　要：光栅立体图在人物、风景、地貌的三维表达方面有着较为广泛的应用,但尚未见于区域地面沉降凹陷形态的表达。在阐述光栅立体成像原理的基础上,以J50幅1∶100万地面沉降专题图为数据源,对地面沉降速率等值线进行立体仿真,生成仿真场景的不同视角图像序列,抽样合成为光栅底图,进而将该底图与柱透镜光栅板整合印刷,形成地面沉降光栅立体图。研究表明,利用三维地理信息系统、数字图像处理和光栅立体成像技术,可对地面沉降信息进行新颖、直观的表达。Lenticular stereoscopic images have been widely used in the three-dimensional expression of characters,landscapes and geomorphic features,but they have not yet been found in the visualization of depression shape of regional subsidence.Based on the research and introduction of the lenticular stereoscopic principle,the authors produced a lenticular stereoscopic subsidence map.The J50thematic map of land subsidence at the scale of1:1000000was used as the data source.After the three-dimensional simulation using the subsidence isoline,the images series with different viewing angles were generated based on the simulated scene.Then,the images series were sampled and arranged to compose the base map.Finally,the base map was printed on the lenticular plate and properly processed.The research shows that the subsidence field can be innovatively and intuitively visualized using3D GIS,digital image processing and lenticular stereoscopic technology.
