This paper first introduces a metric mapping algorithm for urban roads, which generates an occupancy grid map of road surfaces and boundaries. Based on the metric map, we further propose an approach to extract a topo-metric graph which captures both topological and metric information of the road network. As a detailed model of the urban roads, the metric map can be used for obstacle avoidance and local path planning, while the topo-metric graph as a compact representation that can be used for some high-level reasoning processes. Our proposed algorithms are tested in real experiments, and have shown good results. © 2013 IEEE.||Source Title:||IEEE Conference on Robotics, Automation and Mechatronics, RAM - Proceedings||URI:||http://scholarbank.nus.edu.sg/handle/10635/86020||ISBN:||9781479911998||ISSN:||2158219X||DOI:||10.1109/RAM.2013.6758570|
