Abstract: The present disclosure provides an intersection vertex height value acquisition method and apparatus, an electronic device and a storage medium, and relates to the field of artificial intelligence such as intelligent transportation. The method may include: determining roads with starting points or ending points located in a to-be-processed intersection; and performing, for any vertex in a polygonal intersection region corresponding to the intersection, the following processing: determining a road corresponding to the vertex, taking the determined road as a matching road of the vertex, and determining a height value of the vertex according to height values of endpoints on a road center line of the matching road.
