Abstract

In this paper we present algorithms for automatically generating a road network description from aerial imagery. The road network inforamtion (RNI) produced by our algorithm includes a composite topoloigical and spatial representation of the roads visible in an aerial image. We generate this data for use by autonomous vehicles operating on-road in urban environments. This information is used by the vehicles to both route plan and determine appropriate tactical behaviors. RNI can provide important contextual cues that influence driving behaviors, such as the curvature of the road ahead, the location of traffic signals, or pedestrian dense areas. The value of RNI was demonstrated compellingly in the DARPA Urban Challenge , where the vehicles relied on this information to drive quickly, safely and efficiently. The current best methods for generating RNI are manual, labor intensive and error prone. Automation of this process could thus provide an important capability. As a step toward this goal, we present algorithms that automatically build the skeleton of drivable regions in a parking lot from a single orthoimage. As a first step , in extracting structure, our algorithm detects the parking spots visible in an image. It then combines this information with the detected parking lot boundary and information from other detected road-markings to extract a skeleton of the the drivable regions within the lot.
