Three-dimensional road network construction method and apparatus, electronic device, and storage medium

An electronic device, comprising a memory and one or more programs, the one or more programs being stored in the memory and configured to be executed by one or more processors and causing the electronic device to perform a three-dimensional road network construction method, the method including:

• obtaining a two-dimensional road network, the two-dimensional road network comprising a plurality of paths, each path being formed by connecting a plurality of nodes;
• determining a relative elevation for a node of a current path overlapping the current path and/or another path among the nodes of the current path, the relative elevation representing a height of the current path at the node from a reference plane;
• determining relative elevations of nodes constituting a center line of the current path according to the relative elevations of the nodes of the current path and a width of the current path;
• and
• constructing a three-dimensional road corresponding to the current path according to the width of the current path and the relative elevations of the nodes of the center line of the current path to obtain a three-dimensional road network.

A non-transitory computer-readable storage medium, storing instructions, the instructions, when executed by one or more processors of an electronic device, causing the electronic device to perform a three-dimensional road network construction method, the method including:
