This paper presents a method for automated pointcloud-to-map registration using a plane matching technique. The registration is
based on estimating a transformation between a set of planes inferred from the map and their corresponding planes extracted from
the pointcloud. A plane matching algorithm is developed to search for corresponding planes in the pointcloud and map coordinate
systems, and estimate the transformation between the corresponding planes. The search for correspondences takes advantage of an
initiate-and-extend strategy to avoid high computational cost of an extensive search. The search strategy is further strengthened by
using a linear model for the estimation of the transformation. The plane matching algorithm is shown to perform robustly in the
presence of outlier and missing planes, and achieve accuracies in the order of centimetres as the mean distance between the
transformed pointcloud planes and the map planes.
