%X 提出一种利用iBeacon技术辅助PDR的室内定位方法. 采用粒子滤波器将PDR和iBeacon技术定位信息融合，从而确定出用户的位置，以此减少PDR随距离增加而产生的累积误差. 此外，基于iBeacon在线步长调整模型在一定程度上减少了步长不正确带来的误差. 实验结果显示，提出的方法能够有效克服PDR产生的累积误差，有效提升了定位的鲁棒性和精度.<br>This paper presents a method for indoor location by using iBeacon auxiliary for PDR. The method uses particle filter to fuse PDR and iBeacon to determine the location of the user，so as to reduce the cumulative error caused by the increase of PDR with the increasing walking distance. Furthermore，based on the iBeacon online step size adjustment model，the error caused by the step length is decreased to a certain extent. In the paper， the experiments prompted that the proposed method can effectively overcome the cumulative error generated by PDR， and validly improve the robustness and accuracy of locationing
