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.

Key words: indoor positioning, rapid collection, Kriging interpolation, geomagnetic reference map, dynamic time warping algorithm
