As a robot/vehicle travels, we extract a sequence of heading-length values for straight segments from the trajectory and match the sequence with a pre-processed heading-length graph (HLG) abstracted from the prior known map to localize the robot under a graph-matching approach.

In the back end, we optimize the map imposing the constraint that the line segments of the same cluster should be the same.
