Abstract

The invention discloses a high-precision map and two-dimensional map matching method and device and electronic equipment, and the method comprises the steps: determining a road reference line according to a lane center line in the high-precision map; wherein the road datum line is a vector line segment used for describing the road driving direction; determining a lane center line corresponding toeach road datum line; determining a road section corresponding to each road datum line according to the coordinates of the lane center line, the coordinates of the road sections in the two-dimensionalmap, the geometrical shapes of the road datum lines and the geometrical shapes of the road sections; determining the lane center line corresponding to each road section according to the correspondingrelation between the lane center line and the road datum line and the corresponding relation between the road datum line and the road sections; and matching the high-precision map with the two-dimensional map according to the corresponding relationship between the road section and the lane center line.

Description

technical field [0001] The present invention relates to the technical field of map matching, and more specifically, the present invention relates to a matching method, device and electronic equipment for a high-precision map and a two-dimensional map. Background technique [0002] The precise location information in the high-precision map can assist the sensor to identify objects, obtain rich road experience information in advance, and the sub-meter-level lane positioning provided by itself can better improve vehicle safety, which is indispensable for automatic driving. important frame of reference. [0003] However, the current domestic technology for collecting and producing high-precision maps is not yet mature, and high-precision maps have not yet fully covered, so long-distance route planning in the navigation process still needs to use traditional two-dimensional navigation electronic maps. [0004] In the actual navigation process, high-precision maps and two-dimensi...
