移动增强现实在纸质地图中的应用

纸质地图曾是人类进行空间认知的重要工具。随着信息时代的科技发展,电子地图、网络地图等地图产品迅速崛起,而纸质地图存在较多固有缺陷,如一经出版便无法再更改、实时性差、信息量有限、呈现方式静态、缺乏动态效果和交互性等,因此受到较大冲击。移动增强现实技术给纸质地图的多样化表达提供了新的方向,有着广阔的应用前景。本文在对移动增强现实关键技术进行分析的基础上,通过实验开发了一个基于纸质地图的移动增强现实系统,将视频、三维地形模型等数字媒体与纸质地图相结合,实现了纸质地图的增强表达。

Application of Mobile Augmented Reality in Paper Map

Paper maps have been an important tool for human spatial cognition. In the wake of developments in science and technolo-gy, a variety of map products comes along. However, there are some inherent defects in the traditional paper map. For instance, it can' t be changed once published;contains limited information;and its real-time performance is also poor. In addition, static ren-dering mode, lack of interaction and dynamic effect also slow down the development of traditional paper map. The mobile augmented reality makes it possible to present the traditional paper map vividly, and it has wide application prospects. In this paper, a mobile augmented reality system that can combine video, 3D terrain model with paper map is developed for the augmented expression of paper map based on the analysis of the key technologies of mobile augmented reality.
