Abstract: The present disclosure provides a route processing method and apparatus. The specific implementation includes: acquiring a vehicle driving route according to a standard definition map, where the vehicle driving route comprises multiple standard definition map road sections of the standard definition map; determining at least one first road section from the multiple standard definition map road sections according to a road section mapping relationship between the standard definition map and a high definition map, where each first road section has a unique corresponding target road section in the high definition map; determining the target road section corresponding to each first road section in the high definition map according to the road section mapping relationship; and determining a target driving route corresponding to the vehicle driving route in the high definition map according to the target road section corresponding to each first road section and the high definition map.

Abstract: The present disclosure provides a map processing method and apparatus. The specific implementation scheme is: determining a road to be processed in a map, where the road has a first edge line and a second edge line; performing interpolation processing on M gauge points on the first edge line to obtain a first point set of T first sampling points on the first edge line and performing interpolation processing on N gauge points on the second edge line to obtain a second point set of T second sampling points on the second edge line; determining a corresponding relationship between the T first sampling points in the first point set and the T first sampling points in the second point set; and determining a center line of the road in the map according to M, N and the corresponding relationship.
