摘要
基于位置的服务应用已经包含了人们生活的方方面面,这也使得人们对位置信息的需求越来越大。在室外我们可以依赖美国GPS和中国北斗等来获取精确的位置信息,但在复杂的室内环境中,由于卫星信号的极速衰减,无法提供满足人们要求的室内位置信息,同时没有普适性的室内定位解决方案,室内定位仍是研究热点。文章简单介绍什么是定位,然后对室内定位算法和定位介质进行了分类和简单介绍,最后对不同定位介质从不同方面进行了比较并指出了当前室内定位方案存在的问题。
Location-based service applications have already included all aspects of people's lives,which makes people's demand for location information more and more.In the outdoor environment,we can rely on GPS and Bei-dou to obtain accurate location information.However,in the complex indoor environment,due to the rapid attenuation of satellite signals,indoor location information that meets people's requirements cannot be provided.Meanwhile,there is no universal indoor location solution,so indoor location is still a research hotspot.Article introduces what is the location,and then to indoor localization algorithm and positioning media has carried on the classification and simple introduction,and finally compares the different positioning media from different aspects and points out the problems existing in the current indoor positioning scheme.
