基于增强现实技术的纸质地图增强表达与交互

Visualization and Interaction of Augmented Paper Maps Based on Augmented Reality

近年来随着计算机技术的发展,特别是增强现实技术的出现,使纸质地图的"增强"表达和交互分析成为可能。文章探讨了基于增强现实技术的纸质地图增强表达与交互分析流程方法,认为纸质地图增强表达和交互功能的关键技术在于:纸质地图标识的计算机识别,增强地图的空间匹配方法,增强地图的显示和交互方法;同时通过实验研发了原型系统并予以实现。利用增强现实技术扩展了纸质地图的可视化表达方法,把丰富的地理信息和纸质地图结合起来,打破了传统地图可视化的静态表现形式,提供了丰富的人机交互方式,能增强人对地理信息的多维动态感知能力,也增强补充了地图对现实世界的描述。

With the development of computer technology in recent years, especially that of the Augmented Reality technology, visualization and interaction of augmented paper maps become available. In this paper the processes and methods of visualization and interaction of augmented paper maps based on Augmented Reality technology are discussed. A prototype system of augmented paper maps is developed and achieved through the experiment. The authors consider that Augmented reality technology would extend the paper maps＇ visual expression methods. A lot of geographic information and paper maps can be combined to break the static representation of the traditional paper map visualization. Augmented paper maps would provide a wealth of human-computer interaction methods, enhance the perception of multi-dimensional dynamic geographic information and augment the description of map of the real world.
