中文摘要：

针对仅利用无线信号源和其发射信号强度定位会丢失待测位置与信号源之间固有空间关系的问题,提出了利用已知位置接收信号源发射的无线信号强度测量未知点的低成本室内定位方法。该方法深入分析了待定位点和无线信号源以及信号覆盖范围之间的空间关系,充分利用RCC-8空间关系模型进行无线定位。实验结果表明,采用这种融合空间拓扑关系的基于无线信号强度的室内定位方案能够优化定位流程,并在测得位置中反映待测点和信号源之间的相对空间关系。

英文摘要：

To address the demand for indoor low cost positioning environments, this paper focuses on overcoming the ignorance of intrinsic spatial relationships between the surveying point and signal transmitters, and uses wireless signal transmitter and signal strength to localize objects. This method firstly thoroughly investigates the spatial relationships among points to survey, wireless transmitters and signal cov ering scopes, and then utilize the Region Connection Calculus-8 （RCC-8 in short） model to optimize the localization process. The experiment result has proved that the indoor wireless localization plan fusing the RCC-8 model is capable of optimizing the indoor positioning workflow, and demonstrate comparative spatial relationships between surveying points and wireless signal sources.
