1. A route processing method, comprising:
acquiring a vehicle driving route according to a standard definition map, wherein 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, wherein 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, wherein the target driving route comprises each target road section and a filling road section, and the filling road section is a road section other than the target road section in the target driving route
wherein the determining the 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 comprises:
determining at least one candidate route comprising each target road section in the high definition map according to the target road section corresponding to each first road section, wherein an endpoint of each candidate route is the same as an endpoint of the vehicle driving route; and
determining the target driving route corresponding to the vehicle driving route in the high definition map according to a number of the candidate route;
and wherein the determining the target driving route corresponding to the vehicle driving route in the high definition map according to the number of the candidate route comprises:
determining, according to a second road section other than the first road section in the multiple standard definition map road sections, a target road section corresponding to each second road section in each candidate route when the number of the candidate route is more than one, wherein the filling road section comprises the target road section corresponding to each second road section; and
determining a driving route composed of the target road section corresponding to each first road section and the target road section corresponding to each second road section as the target driving route.
