摘要：In this paper, we present a prototype system for semi-automatic extraction of road axes and a study on its efficiency for operational use. The core of our system is a road tracker based on profile matching. This road tracker is enhanced with a graphical user interface that guides the operator through the whole data acquisition process. For typical tasks and problems that occur during the extraction process the system provides road specific options for interaction. I.e., the system monitors the behavior of the tracking module, identifies problems, reports information to the operator, and if necessary asks the operator for his decision or action. In order to evaluate the efficiency of our system we compared it to manual plotting of road axes
