More Information
Summary:The invention provides a road network construction method and apparatus, and an electronic device. The method comprises the steps of obtaining crowdsourcing trajectory information and environment perception information; performing hierarchical processing on the crowdsourcing trajectory information based on a plurality of preset height ranges to obtain crowdsourcing trajectories corresponding to the preset height ranges; for each preset height range, constructing a corresponding region image based on the corresponding crowdsourcing trajectory and the environment perception information; performing image recognition on the regional image to obtain a regional road network of the preset height range; connecting the regional road networks of the plurality of preset height ranges to obtain a target road network; according to the method provided by the invention, the crowdsourcing trajectory data is subjected to hierarchical processing, so that the regional road network of each layer can be determined according to th
