摘　　要：智能手机的广泛地应用,使得智能生活领域的实用范围迅速扩大。为了充分利用智能手机自有条件,设计一种利用可见光外接收器和手机传感器联合采集信号的室内无线定位方法。该方法利用手机自有但功能单一的光线传感器及陀螺仪等传感器,设计功能简单的外接辅助设备,获取无线光信道所传输的信息,然后采用改进的双接收端定位算法,得到终端的实际坐标,最后通过仿真实验验证该方法单位范围内的定位误差在25cm内,满足室内定位需求。The wide application of smart phones makes the practical range of intelligent life expand rapidly.In order to make full use of smart phone's own sensors,an-indoor wireless positioning method is designed,which uses a visible light external receiver and mobile phone sensors to collect signals.This method uses the mobile phone's functional single light sensor,gyroscope,other sensors and simple auxiliary equipment to obtain the information transmitted by the wireless optical channel, and then uses the improved dual receiver positioning algorithm to get the actual coordinates of the terminal.Finally,the positioning error verified by simulation experiments is in the range of 25cm, which fulfills indoor positioning requirements.
