Lane-level high-precision computable road network construction method and device and electronic equipment

The invention discloses a lane-level high-precision computable road network construction method and device and electronic equipment, and the method comprises the steps: obtaining marking line data and directed road section reference lines, screening a target marking line type, and grouping each marking line in the marking line data; the vector direction of the marked line is adjusted, and endpoint information of the marked line is generated; aggregating to obtain a center point of the marking line and sub-road section nodes, and sorting the sub-road section nodes according to the traffic flow direction; after a target marking line is determined, the target marking line is interrupted, a new marking line and corresponding end point information are generated, and a new breakpoint-sub road section node topology model is constructed; extracting adjacent marking lines and generating lanes according to the sorting result of marking line end points in the sub-road section nodes, and aggregating the lanes into a lane
