针对基于 wifi 指纹的室内定位中存在的定位精度不高的问题，提出一套基于加权三点定位的 wifi 指纹定位系统。首先利用最近邻匹配方法进行 wifi 指纹定位，选择出参考点；其次利用多个参考点进行加权三点定位。实验表明，相对于单独使用 wifi指纹定位技术，该系统可以有效提高室内定位的精度和稳定性，并具有较高的实时性。

Considering the problem of lower accuracy of the indoor localisation using Wi-Fi fingerprints technology,we propose a weighed three-point fix-based Wi-Fi fingerprints localisation system.Firstly,we use nearest neighbour matching method to make Wi-Fi fingerprints localisation and chose reference points.Secondly,we use multiple reference points to conduct weighted three-point fix in localisation. Experiments demonstrate that relative to the localisation system using Wi-Fi fingerprints alone,the proposed system can effectively improve the accuracy and stability of indoor localisation,and the real-time property is satisfied as well.
