摘　　要：室外精确定位的方法有很多,通过GPS、北斗等可以完成精确定位,但是室内定位主要依赖于基站扇区和Wi-Fi位置完成,定位精度很差。如何在室内进行精确定位是一个技术热点。通过演算、推导等室内定位算法,结合当前的技术水平,提出精度达0.3 m左右的精确室内定位算法,为室内无线网络优化、无线应用、无人商店、智能机器人控制提供了广阔应用前景。The outdoor precise positioning can be achieved in many ways such as GPS,BeiDou,etc.,but indoor positioning mainly depends on the locations of base station sectors and Wi-Fi and it merely has poor positioning accuracy.Hence,how to perform precise indoor positioning is a hot topic.Through the derivation of indoor positioning algorithm and the combination with the current technical level,a precise indoor positioning algorithm with an accuracy of about 0.3m is proposed,which provides a broad prospect for indoor wireless network optimization,wireless applications,unmanned shops and intelligent robot control.
