摘要:
定位对于当下智能生活的理念有着至关重要的作用.对于室外定位,GPS是一项可靠易得的技术.而当今,随着智能家居等的推广,以及定位技术的日渐发展,室内定位技术越来越受到关注.GPS在室内环境搜索到的信号很弱,无法在室内环境使用,另外其在精度方面也无法满足需求.而目前流行的室内定位技术中大多依赖于智能手机的传感器实现,而单一传感器的定位,精度与稳定性不高,降低了定位的体验.其中,基于磁场的室内定位技术与基于Wi-Fi的室内定位技术是当前流行的技术手段,但是,单独的磁场定位与Wi-Fi定位两种技术都有各自的缺陷,定位效果并不理想.因此,文中利用智能手机采集室内的Wi-Fi信号与磁场信号,再利用改进的粒子滤波算法进行定位,有效地提高了定位效果.
Abstract:
Positioning for the current intelligent life has a crucial role. For outdoor positioning,GPS is a reliable and accessible technology.And today,with the promotion of smart home and the development of positioning technology,indoor positioning technology gets more andmore attention. Signal of GPS in the indoor environment is too weak to be used,and in terms of accuracy it cannot meet demand. And thecurrent popular indoor positioning technology mostly relies on the smart phone sensors to achieve,but accuracy and stability of a single sensor positioning are not high,so that it will reduce the positioning experience. Among them,the magnetic field-based indoor positioningtechnology and Wi-Fi-based indoor positioning technology are the current popular technical means,but the separate magnetic field positio-ning and Wi-Fi positioning have their own flaws. Therefore,we use the smart phone to collect the Wi-Fi signals and the magnetic fieldsignals in the room,and then use the improved particle filter algorithm to position,which can improve the positioning effect.
