Abstract

The embodiment of the invention provides a positioning method and device based on an electronic map. The method comprises the steps of obtaining a location point and a first direction in the electronic map at present; searching for one or a plurality of navigation objects in a preset range in the electronic map; establishing a coordinate system according to the first direction; calculating azimuth information of the one or plurality of navigation objects relative to the location point in the coordinate system. Since the coordinate system is established by taking a user himself as a reference, the most intuitive sense of direction is provided to the user, the simplicity and convenience of positioning operation are improved, the positioning is conducted through the azimuths of the navigation objects, one or a plurality of auxiliary objects is used as a reference and the positioning accuracy and success rate are greatly improved.

Description

technical field [0001] The invention relates to the technical field of electronic maps, in particular to an electronic map-based positioning method and an electronic map-based positioning device. Background technique [0002] As the Global Positioning System (Global Positioning System, GPS) is more and more widely used, various location services (Location Based Services, LBS) based on geographic location are also developing rapidly, such as personal location positioning services, route navigation services, surrounding Search services, etc., the development of LBS has brought a lot of convenience to people's work and life. [0003] When a user uses an application program that provides geographic location services for positioning, the application program cannot locate accurately, and usually can only give the approximate location or location description information of the user. [0004] For example, when a user locates on Liangma Bridge using an electronic map that provides g...
