Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0029] Such as figure 1 As shown, the embodiment of the present application discloses a road matching method, which includes:
[0030] Step 101: Acquiring a set of candidate matching roads for a point of interest, the set including at least one candidate matching road;
[0031] The road matching method disclosed in the embodiment of the present application can be applied to map navigation applications or taxi-hailing applications. If applied to map navigation applications, the poin...

The invention discloses a road matching method and device. The method includes obtaining the alternative matching road set of an interest point, wherein the set includes at least one alternative matching road; obtaining included angles between the vertical lines of the interest point to the alternative matching roads and a preset datum line as orientation angles of the alternative matching roads relative to the interest point; determining the orientation angle matching costs of the alternative matching roads according to the orientation angles of the alternative matching roads relative to theinterest point and the orientation angles of pre-collected interest points; adjusting the initial matching costs of the alternative matching roads according to the orientation angle matching costs ofthe alternative matching roads, and obtaining the road matching costs of the alternative matching roads; and obtaining the matching road of the interest point from the alternative matching road set according to the road matching costs of the alternative matching roads. Thus, relatively accurate roads can be matched for the interest point through the method and device.
Description
technical field [0001] The present application relates to the technical field of electronic maps, and more specifically, to a road matching method and device. Background technique [0002] In the electronic map, real roads are represented by line segments, and the line segments interweave to form a road network. Road matching refers to the process of matching Point of Interest (POI) to roads. Currently, road matching generally calculates the distance from a POI to the perpendiculars of its surrounding roads, and selects the road with the shortest perpendicular distance as the road for POI matching. The inventors found that the accuracy of determining the road for POI matching by the distance of the vertical line is insufficient. Contents of the invention [0003] In view of this, the present application provides a road matching method and device, which can match a relatively accurate road for a point of interest. [0004] In order to achieve the above purpose, the propo...
