Description

A return method and navigation device

technical field

The embodiments of the present invention relate to the field of navigation, and in particular, to a return method and a navigation device.

Background technique

Navigation equipment refers to equipment with various functions related to location, such as navigation or positioning, such as portable navigators, car navigators, tablet computers, computers or mobile phones. Its working principle is that the navigation device determines the position coordinates of a specific location, and matches them with the position coordinates recorded in the electronic map stored by itself, so as to determine the exact position of the navigation object equipped with the navigation device in the electronic map. There is a memory in the navigation device to store data such as electronic maps, address books, and personal favorites. Navigation objects can be vehicles, pedestrians, etc. After the user sets the starting point and the destination, the navigation device will calculate the navigation route according to the electronic map data stored in itself, and guide the user according to the calculated navigation route. With the continuous advancement of technology, a device that receives various location services such as navigation and positioning provided by a remote terminal (such as a server) can also be called a navigation device.

The return service provided by the existing navigation equipment is generally specifically to simply exchange the destination used by the user for the last navigation and the departure place, that is, set the destination as the return departure place, set the departure place as the return destination, and reset the destination to the return destination. Plan the navigation path between the new destination and the departure place for navigation. If the user navigates multiple times during the use of the navigation device and then uses the return function, it may cause that the return flight cannot return to the departure place that the user really wants to return to. .
