摘要
近些年来室内定位技术得到广泛的关注,从大型购物商场的室内定位导航到地下停车场的定位,人们对室内定位需求开始变得越来越紧迫。全球定位系统(GPS)成功解决室内定位的精度问题,然而室内复杂的钢筋混凝土结构对GPS的信号干扰较大,因此GPS技术在室内不在适用。到目前为止,基于Wi-Fi、蓝牙、可见光、超声波、无线射频信号等技术被大量学者讨论和研究。其中基于地磁指纹的室内定位方式是解决室内定位难题较为有效的解决方案。基于地磁指纹的典型研究和实际产品分别主要有GROPING和IndoorAtlas。详细阐述基于地磁指纹的室内定位的研究现状和实际产品。
Indoor positioning technology has received extensive attention in recent years, from the indoor positioning navigation of large shopping mall to the location of underground parking lot, the need for indoor positioning is becoming more and more urgent. GPS successfully solves the accuracy problem of indoor positioning, however, the complex reinforced concrete structure indoor is more disturbing to GPS signal, so GPS technology is not applicable indoor. Up to now, technologies based on Wi-Fi, Bluetooth, visible light, ultrasonic and radio frequency signal have been discussed and studied by a large number of scholars. Among them, the indoor positioning method based on the geomagnetic fingerprint is an effective solution to solve the problem of indoor positioning. the typical research and actual products based on the geomagnetic fingerprint mainly include GROPING and IndoorAtlas. Elaborates the research status and practical products of indoor positioning based on the geomagnetic fingerprint.
