摘要: 主要对基于WiFi信号的室内定位技术中的三角形定位法进行了研究。鉴于现有的三角形定位模型受信号强度和环境干扰的约束影响,定位精度不高,提出了一种结合室内影响因素约束的权重改正定位模型,更加切合复杂的室内定位环境。通过试验测试和数据分析,经过加权去噪模型改正后的定位精度更高,适用性更广。

Abstract: In this paper, we mainly study the triangle positioning method based on WiFi signal indoor positioning technology, in view of the existing model by triangle positioning signal strength and environmental interference, the positioning accuracy is not high, this paper proposes a weight correction model, which is based on the constraints of indoor influence factors. Through the experimental test and data analysis, the accuracy of the corrected model is higher and the applicability is wider.

Key words: indoor localization technology, WiFi positioning, triangle positioning, positioning accuracy, computational model
