一种联合WiFi信息和PDR算法的智能手机室内定位方法

A Smart Phone Indoor Positioning Method Combining WiFi Information and PDR Algorithm

受室内复杂环境的影响,实现满足各类室内定位需求、准确实时的定位仍有很大的挑战性。提出了一种联合WiFi信息和行人航位推算(pedestrian dead reckoning,PDR)算法的智能手机室内定位方法,并给出了其原理和流程。实验结果表明,该方法适应性较强、定位结果准确。

Due to the influence of complex indoor environment,it is still a great challenge to meet the needs of various indoor positioning and achieve accurate and real-time positioning. Accordingly,we propose a method for indoor positioning based on smartphones,which combines WiFi information and pedestrian dead reckoning(PDR)algorithm. Its principles and flow chart are also given. The experimental results show that the proposed method has better adaptability and accurate positioning results.
