高精度车内定位技术是提供车内智能服务、进行车内用户行为习惯分析等应用的基础,有重要实用价值。低功耗蓝牙(BLE
bluetooth low energy)的RSSI(received signal strength indicator)值可用于定位系统的分析计算。针对无线信号传输易受环境影响的问题,对车内定位提出了一种基于蓝牙多信道多RSSI值(multi-channel multi-RSSI values)的车内定位方法 VehLoc。接收端在传统的采集蓝牙 RSSI 信号的基础上,同时记录信号的信道来源,通过使用3个蓝牙信标在其不同信道的RSSI值对使用者终端在车内的位置进行粗细粒度与分布相结合的区域分析和位置判断。实验结果表明,VehLoc定位方法对车内5个主要位置的分类正确率均可达90%。
High precision in-vehicle positioning is the basis of providing smart in-vehicle service
passengers' behavior analysis and other issues
and has important practical value. The RSSI (received signal strength indicator) values of BLE (bluetooth low energy) can be used to do analysis and computation in location system. To deal with the problem that RSSI is vulnerable to environmental issues
an in-vehicle location method called VehLoc based on BLE multi-channel multi-RSSI values was proposed. By using a plurality of Bluetooth transmitters
the location of the receiving terminals in the vehicle was analyzed by combining the coarse
fine classifier and distribution fitting of the user's RSSI values in different channels. The experimental results show that the average accuracy of VehLoc in the five main positions in-vehicle classification can reach 90%.
