Method of automatically generating road network information and system for embodying the same

摘要

Center lines, i.e., precise road network information may be extracted relative to road margin information in a large-scale map based on teaching road network information (first configuration:S101). Then, center lines, i.e., detailed road network information may be extracted relative to narrow road margin segments whose respective road plane sides have not defined yet, on the basis of road margin segments whose respective road plane sides have already been defined (second configuration:S102). Then, finished road network information may be extracted by correcting road network information derived from the second configuration (third configuration:S103). <IMAGE>
