论文摘要
基于RSS的室内定位的基本思想是通过将所测量的接收信号强度指示器(RSSI)与预先建立的RSSI集合匹配,并具有相应的位置,称为无线电图。因此,构建准确的无线电图直接与基于RSS的室内定位中的准确定位性能有关。基于RSS的室内定位可以轻松地使用调查每个位置的无线电图进行进行,但是当地图区域包含物理上无法到达或拒绝访问的位置时,无法构建完整的无线电图。另外,在调查过程中可能会出现测量误差或设备问题,从而导致无线电图降解。我们分析了在实际的RSSI调查中发生的事件,这些事件可能破坏无线电图的构建以及提出的方法以构建更准确的无线电图。
The basic idea of RSS-based indoor positioning is to estimate the receiver location by matching the measured received signal strength indicator (RSSI) with preestablished RSSI collections with corresponding locations, known as the radio map. Hence, constructing an accurate radio map directly relates to accurate positioning performance in RSS-based indoor positioning. RSS-based indoor positioning can be easily conducted with a radio map that surveys every location, but a complete radio map cannot be constructed when the map area includes locations that are physically impossible to reach or denied access. In addition, measurement errors or device problems can occur during the survey, resulting in degradation of the radio map. We analyzed incidents that occurred in actual RSSI surveys that could disrupt the construction of the radio map and proposed methods to construct a more accurate radio map.
