【摘要】 基于指纹库进行室内定位,传统的数据采集方式为单点采集,这种采集方式既费时又费力,又不利于数据的更新。本文针对地磁数据的特征,提出一种指纹快速采集方法,借助克里金插值算法快速建立地磁数字基准图,并利用动态时间规整算法实现快速定位。通过试验测试和数据分析,快速采集方式的定位精度能够满足用户的位置服务需求,具有较高的实用价值。更多还原

【Abstract】 In the technology of indoor positioning based on fingerprint database,the traditional data collection method is single point collection,which is time-consuming and laborious,and is not conducive to the updating of data. According to the characteristics of the geomagnetic data,this paper presents a fast fingerprint acquisition method,with the help of Kriging interpolation algorithm quickly built geomagnetic digital reference map,and uses the dynamic time warping to achieve rapid positioning.Through experimental test and data analysis,the positioning accuracy of fast acquisition mode can meet the needs of users’ location service and has high practical value.更多还原
