AR技术在GIS可视化中的应用及方法研究

Research on the Applications and Methods of AR Technique to Visualize Geospatial Data

地理数据的增强现实可视化技术,是地理信息科学可视化的一个重要的发展方向之一。首先,笔者详细地综述了国内外AR技术在GIS可视化领域的应用。针对基于真实视频影像表达地理数据的问题,笔者构建了该可视化系统的概念模型;并以户外山区地形数据和影像数据为基础,详细地阐述了AR技术可视化地理数据的原理和方法;最后,实现了以视频影像为载体的地理数据AR可视化方法。与传统地理数据的可视化方式相比,AR可视化表达方式更简单直观,真实感更强。

Augmented reality（AR） visualization of geospatial data can be seen as an important research field in geospatial visualization.Firstly,the paper reviewed current applications on visualization using AR technique.Aiming at visualization of geospatial data by video images,a preliminary concept model of visualization system was presented.Based on the terrain and image data obtained from mountain area,the principles and methods to visualize geospatial data by AR technique was discussed.Finally,the AR visualization of geospatial data expressed in video images is realized.The demonstration shows that AR visualization is simpler,more efficiency,and more realistic than traditional visualization methods.
