A method for defining a following path for a following vehicle to autonomously follow a leader, the method including acquiring waypoints associated with a path that the leader traverses; filtering the acquired waypoints, wherein the filtering removes waypoints located outside an area of interest; generating intermediate waypoints by interpolating between adjacent pairs of the filtered waypoints if the adjacent pairs of the filtered waypoints are separated by a distance that exceeds a threshold distance; and defining a following path through the filtered waypoints and the intermediate waypoints using a least-squares spline fit to calculate the following path.
