Abstract: The road extraction from aerial images is always a hotspot in research. The algorithm of road extraction based on dynamic programming is one of the most efficient algorithms, which is improved in this paper based on LiDAR point-cloud, and the robustness is also increased. In order to combine the aerial image and the LiDAR point-cloud data, the algorithm of matching the aerial image with the LiDAR point-cloud data is researched. Experiments are carried out to validate the algorithm mentioned above.

Key words: computer application, dynamic programming, LiDAR, point-cloud, road extraction, aerial images
