Abstract

The invention discloses a topological road network map establishment method and system, a storage medium and electronic equipment, and the method is used for establishing a topological road network map, and comprises the steps: obtaining a track data set based on the GPS data of a traffic vehicle; segmenting and compressing the track data set to obtain inflection point information; analyzing inflection point information to obtain intersection nodes; according to the inflection point information and the intersection nodes, analyzing and obtaining road center lines and road vector information, and forming a topological road network map. According to the method, segmentation and compression processing are carried out on the track data set of the traffic vehicle GPS data, then analysis is carried out, the road intersection can be rapidly and accurately recognized, then the road center line and the road vector are extracted, a high-precision visual topological road network map is established. The establishment process is based on analysis and processing of a track data set of a large batch of traffic vehicle GPS data, the requirement for the precision of GPS sampling equipment is not high, the data acquisition way and mode are convenient, and manpower resources and cost are effectively saved.
