AUTOMATIC RECONSTRUCTION OF ROAD CENTERLINES FROM MOBILE MAPPING IMAGE SEQUENCES

An automatic approach to road centerline reconstruction from stereo image sequences acquired by a mobile mapping system is introduced. The road centerline reconstruction is treated as an inverse problem and solved by global optimization techniques. The centerlines are described by a physical curve model, which is composed of an abstract material and deforms according to external and internal forces applied. The external forces, generated from the centerline information extracted from the image sequences, controls the local characteristics of the model. The internal forces, arising from a priori knowledge of the road shape, contribute to the global shape of the model. Unique constraints that exist only in mobile mapping image sequences are utilized. The developed system has been used for processing a large number of mobile mapping image sequences.
