Embodiment Construction

[0025] The method and device for acquiring a map route provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] figure 1 A schematic flow diagram of a method for obtaining a map route provided by an embodiment of the present invention; as figure 1 As shown, the map path acquisition method provided by the embodiment of the present invention includes the following steps:

[0027] Step 101. Obtain multiple paths between the current location and the target location, and obtain a path from the multiple paths as a reference path.

[0028] Step 102 , acquiring multiple recommended nodes on the reference path, and if the distance between two adjacent recommended nodes exceeds a preset split distance, perform a node insertion operation between the two adjacent recommended nodes.

[0029] Step 103 , each node on the reference path after interpolating the nodes obtains the first matching degree of other...

Abstract

The invention provides a map path acquiring method and device. The map path acquiring method comprises the following steps: acquiring a plurality of paths between a current position and a target position, and acquiring a path from the plurality of paths as a reference path; acquiring a plurality of recommended nodes on the reference path, and if the distance between two adjacent recommended nodes exceeds a preset division distance, inserting a node between the two adjacent recommended nodes; for each node of the node-inserted reference path, acquiring the first matching degree of the other paths in the plurality of paths relative to the reference path in a geo-fencing manner; and sequencing the other paths according to the first matching degree to obtain a first candidate path set of the other paths relative to the reference path. The embodiment of the invention can realize effective assessment of the plurality of paths, so as to provide the most suitable path and buddies for outgoing crowds.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for obtaining a map route. Background technique [0002] With the rapid development of the Internet today, the Global Positioning System (Global Positioning System, referred to as GPS) navigation and positioning has become an indispensable travel tool for Internet users. For people who ride or carpool, depending on the purpose of travel, sometimes they need to find someone to go with them. The existing technology determines which road the point is closer to by calculating the vertical distance between each node in the path and its surrounding roads, and finally integrates the calculation results of all nodes to obtain the matching road path, or, by calculating the distance between adjacent nodes in the path The most road paths traversed by the link determine the final matching path. The inventors have found that, in the prior art, it is impossible to pr...
