Abstract

The invention provides an indoor map data building method and device and an indoor positioning method and device. The indoor map data building method comprises the steps that geomagnetic data, collected according to a preplanned indoor map collection path, of each collection point is obtained; according to the geomagnetic data of each collection point, the geomagnetic fingerprint of each collection point is determined; according to the geomagnetic fingerprint of each collection point, the geomagnetic fingerprint of each grid point obtained through partition of an indoor map is determined; the position information of each grid point and the corresponding geomagnetic fingerprint are used as indoor map data to be stored. The indoor positioning method on this basis comprises the steps that the geomagnetic data, collected in real time, of each collection point is obtained; according to the geomagnetic data, collected in real time, of each collection point, the corresponding geomagnetic fingerprint is determined; the determined geomagnetic fingerprint is matched with the indoor map data, and a positioning result is obtained through the position information, obtained through matching, of the grid points. By means of the indoor map data building method and device and the indoor positioning method and device, the geomagnetic data collection workload can be reduced.

Description

【Technical field】 [0001] The invention relates to the field of computer application technology, in particular to a method for establishing indoor map data, an indoor positioning method and a corresponding device. 【Background technique】 [0002] With the rapid development of the mobile Internet, people's needs for positioning and navigation are becoming more and more common. Location-based services play an increasingly important role in people's life and production. GPS (Global Positioning System) has been successfully applied to positioning in outdoor environments, but due to the low accuracy of GPS positioning, it is not enough to locate an accurate position in a small indoor place. And in the urban environment, because the signal transmitted by the GPS satellite is too weak, the blocking of buildings and buildings, etc., reduces the positioning accuracy of GPS; and in the building, the walls will block the satellite signal, resulting in a further increase in positioning e...
