Abstract

The invention relates to a different-source route matching method and system based on road network topology, and the process of matching navigation routes A from different navigation engines into a navigation engine to which a navigation route B belongs comprises the following steps: according to the position and direction of a shape point and the information of a road where the navigation route B is located, matching the navigation routes A and B; matching each shape point in the navigation route A to each road in the navigation route B; generating a road matching result by referring to road topology information in a road network of a navigation engine to which the navigation route B belongs according to the matching information of each shape point; according to the navigation route A and the road matching result, referring to road topology information in a road network of a navigation engine to which the navigation route B belongs, and generating a navigation route in the navigation engine to which the navigation route B belongs; matching routes generated by the navigation engine based on different source map data to obtain a route in the engine; interactive fusion and cooperative use among different-source data navigation engines can be realized, and a user can obtain better experience conveniently.

Description

technical field [0001] The invention relates to the fields of navigation and electronic maps, in particular to a heterogeneous route matching method and system based on road network topology. Background technique [0002] Different map data manufacturers have different data coverage areas and different emphases. As a result, only by combining multiple map data can an optimal navigation device experience be obtained. Because various map data vendors are closed to data, they can only interact through navigation engines. [0003] However, the prior art lacks a navigation engine interaction method, which causes users to be unable to flexibly select the optimal navigation from multiple heterogeneous data navigation engines, which affects user experience. Contents of the invention [0004] Aiming at the technical problems existing in the prior art, the present invention provides a heterogeneous route matching method and system based on road network topology, based on routes gen...
