Road section position matching method and device, navigation method and device and storage medium

Abstract

The embodiment of the invention provides a road section position matching method and device, a navigation method and device and a storage medium. The road section position matching method comprises the following steps: executing map block-based road section exploration on a standard precise map and a high-precision map of a target geographic area, and correspondingly obtaining respective intersection data of the standard precise map and the high-precision map; according to the intersection data of the standard-precision map and the intersection data of the high-precision map, the road section connection relation of the standard-precision map and the road section connection relation of the high-precision map are determined; performing road section exploration according to respective road section connection relations of the standard-precision map and the high-precision map, and determining respective road sections between intersections of the standard-precision map and the high-precision map; the intersections in the standard precision map are matched with the intersections in the high-precision map, and the corresponding relation of the road sections is determined; and matching the position of the road section between the intersections of the standard precise map with the position of the road section between the intersections of the high-precision map to obtain a position matching relationship between the two positions. The scheme of the embodiment of the invention is more beneficial to accurately describing the actual geographic position.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a road section position matching, navigation method, device and storage medium. Background technique [0002] The standard precision map is a kind of electronic map with a high penetration rate. It has the advantages of high coverage and mature production technology. Many traffic application software use the standard precision map to provide efficient navigation services for a large number of users. [0003] However, in the navigation service of the standard precise map, the actual geographic location of the user is often not accurately described, resulting in situations such as unreasonable navigation broadcasts. [0004] Therefore, there is an urgent need for a solution that can accurately describe the user's actual geographic location to improve the user experience of transportation services such as navigation services.
