Abstract

The invention relates to a navigation method and a device capable of accurately searching points of interest around a navigation path. The method includes: inputting POI information; performing POI searching along the navigation path so that a structure of fish bones is formed between the positions of the searched POI information and the current navigation path; establishing corresponding navigation paths; displaying the navigation paths having the structure of the fish bones and navigating. The device comprises an inputting module used for inputting the POI information; a navigation path establishing module used for performing POI searching along the navigation path so that the structure of fish bones is formed between the positions of the searched POI information and the navigation path and is used for establishing the corresponding navigation paths; and a navigation module used for displaying the navigation paths having the structure of the fish bones and navigating. The method and the device can avoid detour caused by a large difference between the actual path and a linear distance.

Description

technical field [0001] The present invention relates to the technical field of car navigation, in particular to a navigation method and device for accurately retrieving points of interest (POI for short) along the periphery of a navigation route. Background technique [0002] The Global Positioning System (GPS) is already the most basic function built into the personal navigation device known to the public, and is widely used in the personal navigation device in the car. A common function of a personal navigation device is to provide a map data analysis to generate appropriate navigation instructions and display the instructions on the screen of the personal navigation device. This type of personal navigation device is usually fixed on the front dashboard of the vehicle with suction cups or other kinds of fixing elements. [0003] A personal navigation device generally refers to a device that can guide a user to a predetermined destination. Such devices usually have a buil...
