Abstract

The invention provides a map navigation method. The method comprises the following steps: a server receives a real time image sent by a mobile terminal and navigation condition information for confirming a navigation path, wherein the navigation condition information includes information of a navigation destination; comparing the real time image with a data image in an image database, and determining the current position and direction of the mobile terminal; calculating a navigation path from the current position to the navigation destination according to the navigation condition information; and obtaining the traveling direction identifier information of the navigation path according to the navigation path, the traveling direction of the navigation path and the current position and direction of the mobile terminal, and sending the traveling direction identifier information to the mobile terminal. The invention also provides a map navigation apparatus and a system thereof. The map navigation method, the apparatus and the system realize map navigation of the real time image shot by a user, and can improve the navigation efficiency.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a map navigation method, device and system. Background technique [0002] Navigation is the method of guiding a device from one point to another on a specified course. With the development of Internet and mobile terminal technology, more and more map navigation applications (APP, APPlication) based on various intelligent mobile terminal platforms are used by people to make people travel more convenient. [0003] At present, navigation APPs commonly used in smart mobile terminals generally adopt Global Positioning System (GPS, Global Positioning System) positioning technology to receive signals from positioning satellites, obtain necessary navigation and positioning information, and complete navigation and positioning through data processing. [0004] However, in the above-mentioned prior art, there is a certain distance error in positioning, which leads to insuffi...
