摘要: 目前的手机导航方式多局限于平面图文,为使用户获得更直观、立体和真实的导航体验,提出一种基于Android智能手机传感模块的增强实境浏览器。考虑到户外场景与导航图文的虚实融合,设计基于手机GPS信息和姿态角的惯性跟踪注册方法,并通过图像复合变换实现动态渲染。针对网络地图获取的GPS数值偏差较大的问题,选择实地采集经纬度信息,利用方差均值化提高采集数据的稳定性。校园内测试结果证明了该浏览器的实用性和可行性。

Abstract: Most navigation applications are confined to 2D image-text on smart phones currently. This paper presents an Augmented Reality(AR) navigation browser based on the sensors of Android smart phones in order to provide the visitor more real and excellent experience and direction. This paper proposes a tracking and registration algorithm based on the GPS and attitude angle of smart phones and realizes rendering by composite graphic transformation to make the outdoor scene and digital navigation information merge. The system chooses recording GPS information on the campus instead of picking the data from network map and stabilized the data collected by mean and variance. The browser in this paper presents the guide information more clearly, interacts with the users more conveniently, and makes the visiting experience more realistic. The experiment result on campus shows its practicability and feasibility.

Key words: Augmented Reality(AR), smart mobile phone, navigation, Location Based Service(LBS), sensors, coordinate transformation
