摘要
考虑到当前广泛存在的室内定位和导航需求,文章将用户随身携带的iPhone手机与室内定位相结合,提出了基于iPhone的室内二维定位系统设计与实现。通过iPhone手机配置的惯性传感器,首先使用苹果公司提供的CoreMotion框架和CoreLocation框架获取用户的移动距离和方向,并对获取的数据进行处理;然后使用行人航迹推算(Pedestrian Dead Reckoning,PDR)算法估算出行人的位置坐标;最后实现室内二维定位结果。实验结果表明,基于iPhone的室内二维定位系统具备一定的可用性和准确率。
Considering the widespread demand of indoor positioning and navigation,the design and implementation of two-dimensional indoor positioning system based on iPhone is proposed by combining the iPhone carried by users with indoor positioning.Through the inertial sensor configured by iPhone,the CoreMotion framework and CoreLocation framework provided by Apple are used to obtain the user's moving distance and direction,and the acquired data are processed accordingly.Then,Pedestrian location coordinates were estimated by Pedestrian Dead Reckoning(PDR)algorithm,and indoor two-dimensional positioning results were finally achieved.The experimental results show that the indoor two-dimensional positioning system based on iPhone has certain usability and accuracy.
