论文摘要
多源融合定位是获得足够的室内定位精度的技术框架之一。为了评估多源融合定位的效果,有必要建立融合误差模型。在本文中,我们首先使用最小二乘方法来融合无线电指纹和PDR定位,然后应用方差传播定律来计算室内多源定位方法的误差分布。基于融合误差模型,我们开发了一个室内定位模拟系统。该系统可以在给定条件下提供更好的定位源布局方案,并可以评估信号强度分布和误差分布。
Multi-source fusion positioning is one of the technical frameworks for obtaining sufficient indoor positioning accuracy. In order to evaluate the effect of multi-source fusion positioning, it is necessary to establish a fusion error model. In this paper, we first use the least squares method to fuse the radio fingerprint and the PDR positioning, and then apply the variance propagation laws to calculate the error distribution of indoor multi-source localization methods. Based on the fusion error model, we developed an indoor positioning simulation system. The system can give a better positioning source layout scheme under a given condition, and can evaluate the signal strength distribution and the error distribution.
