1. A data processing method, comprising:
determining, by a processor, a road to be processed in a map, wherein the road has a first edge line and a second edge line, there are M gauge points on the first edge line, there are N gauge points on the second edge line, and M and N are integers greater than or equal to 2 respectively;
performing, by the processor, interpolation processing on the 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, by the processor, interpolation processing on the N gauge points on the second edge line to obtain a second point set of T second sampling points on the second edge line according to a first length of the first edge line, a second length of the second edge line and a preset point density, wherein T is an integer greater than or equal to 2;
determining, by the processor, a corresponding relationship between the points in the first point set and the points in the second point set;
determining, by the processor, a center line of the road in the map according to M, N and the corresponding relationship, and
keeping a travel track of a vehicle in a center of the road according to the center line of the road.
