Problems solved by technology

[0003] However, when the intelligent terminal in the prior art realizes navigation, it usually realizes the navigation through the positioning of the Global Positioning System (GPS), and when the cloud layer is thick or the intelligent terminal is blocked by a building, etc., the GPS may have positioning inaccuracies. Accurate problems seriously affect the navigation accuracy, and even navigation errors may occur, making the user experience poor

Abstract

The invention discloses a navigation method and device and belongs to the navigation technical field. The method comprises the following steps that: when detecting a signal emitter, a terminal obtains the first location information of the signal emitter; the second location information of the terminal is obtained through GPS positioning; a distance between the signal emitter and the terminal is calculated according to the first location information and the second location information; when the distance between the signal emitter and the terminal exceeds a preset distance, the second location information is corrected according to the first location information; and a navigation path is determined according to the corrected second location information and the location information of a destination, so that navigation can be realized. According to the navigation method provided by the technical schemes of the invention, the location information obtained by GPS positioning can be corrected according to the location information of the signal emitter, and the corrected location information is adopted to perform navigation, and therefore, the problem of inaccuracy of GPS positioning can be avoided to a certain extent, and the navigation accuracy and user experience can be improved.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a navigation method and device. Background technique [0002] Navigation is the process of guiding a certain device from one point of a specified route to another point. Today, with the rapid development of smart terminals, people are increasingly dependent on navigation, whether it is walking or driving a car. It is indispensable. [0003] However, when the intelligent terminal in the prior art realizes navigation, it usually realizes the navigation through the positioning of the Global Positioning System (GPS), and when the cloud layer is thick or the intelligent terminal is blocked by a building, etc., the GPS may have positioning inaccuracies. Accurate problems have seriously affected the navigation accuracy, and even navigation errors may occur, making the user experience poor. Contents of the invention [0004] In view of the above problems, the present invention is ...
