| 摘 要： | 针对缺少全球定位系统情况下的室内定位需求，提出了一种航位推算/接收信号强度指示组合的室内定位算法。基于搭载多传感器的智能移动终端，采用方位传感器监测航向，通过监测Z轴加速度判定步数，利用接收信号强度指示的绝对定位在线更新步长和修正航位推算产生的积累误差，充分发挥了两种定位方法的优势。对采用航位推算/接收信号强度指示组合算法的室内定位系统在安卓平台上进行了实现及有效性验证。

| Abstract: | To meet the requirements of realizing indoor positioning in conditions without the global positioning system, a dead reckoning/Received Signal Strength Indication（RSSI） integrated indoor positioning algorithm is proposed. Based on the intelligent mobile terminals equipped with various sensors, the heading directions are monitored by using the orientation sensor. The number of steps is determined by monitoring the Z-axis acceleration, and the online step length update and the dead reckoning accumulation error amendment are performed by using the absolute positioning of RSSI method. Thus the advantages of both the dead reckoning and the RSSI-based positioning methods are effectively combined. The proposed integrated indoor positioning system is implemented based on the Android platform, and its effectiveness is successfully verified. |
