Problems solved by technology

However, because GPS navigation technology utilizes navigation satellites to measure time and distance, the navigation path set by GPS-based navigation technology for people is usually not accurate enough, resulting in users who can only reach a certain area where the destination is located. In order to reach the target location, people usually need to make additional inquiries, which is time-consuming and labor-intensive

Abstract

The embodiment of the invention provides a navigation path calculation method and device. The navigation path calculation method comprises the following steps: acquiring a start position and a destination location specific to a target scene; according to preset road network data corresponding to the target scene, determining a start road segment corresponding to the start position and a terminatedroad segment corresponding to the destination location, wherein the preset road network data comprise multiple road segments, each road segment is a road part between any two road network nodes, andeach road network node comprises end points of roads and crosspoints among the roads; and according to the start road segment and the terminated road segment, calculating a navigation path from the start position to the destination location. By virtue of the scheme, the accurate navigation path can be provided, so that a user can quickly arrive at the destination location.

Description

technical field [0001] The invention relates to the technical field of spatial information, in particular to a method and device for calculating a navigation path. Background technique [0002] With the development of mobile Internet technology and geographic information technology, location-based services are getting more and more attention. Among them, in an outdoor environment or inside a complex building, it has become a rigid demand to provide users with accurate navigation paths, and this demand has great market potential. [0003] In the prior art, the navigation technology based on GPS (Global Positioning System, Global Satellite Positioning System) has been relatively mature, which makes the navigation products widely used and ensures that people can reach the destination position when the road is unfamiliar and the weather is bad. . However, because GPS navigation technology utilizes navigation satellites to measure time and distance, the navigation path set by G...
