Title:
METHOD, DEVICE AND SYSTEM FOR UPDATING GEOMAGNETIC INFORMATION
Document Type and Number:
WIPO Patent Application WO/2019/154097
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to the technical field of electronics, and provide a method, device and system for updating geomagnetic information. The method comprises: receiving target geomagnetic information and target location auxiliary information sent by a terminal in the locating process; if geomagnetic information corresponding to a current geoimageic location of the terminal fails, determining a target geoimageic location corresponding to the target location auxiliary information; and in a pre-stored corresponding relation between the geoimageic location and the geomagnetic information, updating the geomagnetic information corresponding to the target geoimageic location according to the target geomagnetic information. By means of the embodiments of the present invention, the efficiency for updating the geomagnetic information can be improved.
