Abstract

The invention provides a virtual guide line generation method and device and an electronic map, and the method comprises the steps: obtaining a pre-generated reference line of an intersection, and enabling the reference line to be a reference line which is generated in a road surface region covered by the intersection based on a set driving direction and does not avoid an obstacle located in the road surface region, an avoiding route for avoiding the obstacle is determined according to the reference line, the distance between the avoiding route and the reference line is smaller than a set distance threshold value, a virtual guide line corresponding to the set driving direction is generated according to the reference line, the avoiding route and the obstacle, and the defect that the accuracy is low due to the fact that the virtual guide line is determined based on a manual mode is overcome; the intelligent and automatic determination of the virtual guide line is realized, and the accuracy and effectiveness of the determined virtual guide line are improved.

Description

technical field [0001] The present disclosure relates to the technical field of high-precision maps, and in particular, to a method, device and electronic map for generating virtual guide lines. Background technique [0002] An electronic map is a digital representation of the real world. Most roads in the real world have lane lines drawn on the road surface for vehicles to drive along the lanes. Therefore, when making a high-precision electronic map, the collected road data is Can create lane lines on the road. [0003] However, the inventors of the present disclosure found that the road surface area of ​​the road in the real world usually does not have lane lines. Since the high-precision electronic map mainly serves the intelligent driving vehicle to make driving decisions, in order to enable the decision-making system of the intelligent driving vehicle to make a decision based on the high-precision electronic map The corresponding driving decision instruction needs to g...
