Abstract

Abstract:

Aiming at the problem that the traditional indoor fingerprint localization algorithm has low positioning accuracy and is easily affected by the environment, an indoor

localization algorithm based on deep learning using Wi-Fi and iBeacon is proposed. Signal strength of each AP and iBeacon is collected at each reference point in offline phase, and

is used to train the stacked auto-encoder which is used to extract features from a large number of signal strength samples with noise. These features are used to construct the

fingerprint database. The features of the point to be measured can be obtained by the stacked auto-encoder in online phase. Then these features are matched in fingerprint database.

The position of the point to be measured is estimated by the nearest neighbor algorithm. Experimental results show that the proposed indoor localization algorithm has higher

localization accuracy.

Key words: indoor localization, deep learning, stacked auto-encoder, nearest neighbor algorithm, iBeacon, Wi-Fi

针对传统室内定位指纹法存在定位精度低、容易受到环境影响的问题，提出了一种基于深度学习的Wi-Fi与iBeacon融合的室内定位方法。离线阶段在参考点处采集各个AP和iBeacon的信号强度，使

用这些信号强度数据对堆叠自动编码机进行训练并从大量带有噪声的信号强度样本中提取特征，构建位置指纹数据库；在线定位阶段，使用堆叠自动编码机获得待测点信号强度特征并与位置指纹数据库中信

号强度特征进行匹配，通过近邻算法估计待测点位置。实验结果表明，基于堆叠自动编码机的室内定位算法具有更高的定位精度。
