Abstract

Provided are a positioning method and system for real navigation and a computer readable storage medium. The positioning method for real navigation includes steps of receiving a satellite positioning signal; calculating a satellite positioning coordinate according to the satellite positioning signal; capturing a real scene image of a driving path; recognizing whether an indicator exists in the real scene image; if the indicator exists in the real scene image, calculating an auxiliary positioning coordinate according to the indicator; and calculating a current coordinate corresponding to the driving path according to the satellite positioning coordinate and the auxiliary positioning coordinate.

Description

technical field [0001] The invention relates to a positioning method and a positioning system, in particular to a positioning method and a positioning system for real scene navigation. Background technique [0002] With the mature development of the Global Position System (GPS) and various electronic devices (such as smart phones), the functions of car navigation are becoming more and more perfect and diversified. realized in. Most of the electronic devices that support real-world navigation currently on the market use built-in cameras to capture real-world images, and display the captured real-world images in real-time in the navigation software, replacing the maps in the 2D or 3D map database of the original navigation software. . Combined with the navigation information displayed by the original navigation software, the user can more clearly understand the route indicated by the navigation software on the real street, which greatly improves the recognition rate of the n...
