Abstract
A traffic lane line fitting method includes: obtaining map information for a current position of a vehicle, the map information comprising a number of traffic lanes, a road width and line point information of traffic lane lines on both sides of the vehicle; determining, from among the traffic lane lines on both sides of the vehicle, a traffic lane line on one side, consistent with the direction indicated by at least one of the following, to be a traffic lane line offset reference used for traffic lane line fitting; offsetting and generating a plurality of traffic lane lines of the vehicle on the basis of the traffic lane line offset reference; performing curve fitting on a set of line points on the generated plurality of traffic lane lines so as to obtain a corresponding traffic lane line equation.
