Method and equipment for associating high-precision map with standard map

Abstract

The invention provides a method and equipment for associating a high-precision map with a standard map. The method comprises the steps of: acquiring a lane group in the high-precision map, and generating a road section reference line corresponding to the lane group; acquiring road lines in the standard map; and matching the road lines with the road section reference line, determining the road lines and the road section reference line which have an association relationship, and establishing association between the road lines and the road section reference line which have the association relationship, so that association between a high-precision map and a standard map can be realized. Moreover, the road section reference lines of the high-precision map and road lines of a standard map both represent an actual road section, so that the road section reference lines of the high-precision map can be accurately associated with the road section reference lines by matching the road section reference lines with the road lines.

Description

technical field [0001] Embodiments of the present invention relate to the field of map technology, and in particular to a method and device for associating a high-precision map with a standard map. Background technique [0002] Electronic maps are mainly divided into high-precision maps and standard maps. Standard maps mainly provide positioning, retrieval, and path planning functions in manual driving, while high-precision maps are mainly used for assisted driving or automatic driving. At present, standard maps can cover the entire road network, while high-precision maps only exist in specific scenarios, not all road networks are covered, and the accuracy of high-precision maps can reach the lane level, while the accuracy of standard maps can only reach the road level. [0003] In the prior art, vehicles often switch between standard maps and high-precision maps during driving. For example, after turning on automatic driving, it is necessary to switch the standard map used...

Problems solved by technology

[0004] However, the inventor has found that there are at least the following problems in the prior art: when switching between a standard map and a high-precision map, for example, when switching from a standard map to a high-precision map, it is necessary to find the standard map where the vehicle is currently located The high-precision map lane group corresponding to the road can be switched to the corresponding high-precision map. Therefore, it is necessary to establish a corresponding relationship between the standard map road and the high-precision map lane group, so as to establish the relationship between the high-precision map lane group and the standard map road. The corresponding relationship of the
