Paper Abstract

The US Federal Highway Administration and the Center for Mapping of The Ohio State University are developing a prototype mapping vehicle that integrates a stereo-vision system, a GPS receiver, and some other sensors, to automatically collect data of the environment of roads at highway speeds and store this information in a GIS. Thirty eight states and one Canadian province are sponsoring this effort together with NASA. In this paper we discuss the integration of the stereo-vision system with a GPS-receiver and an inertial system in a mobile workstation. The major task of the vision system is the acquisition and storage of digital image pairs once a second. The shutters of the camera are synchronized by the clock of the GPS receiver. The system will be calibrated by analytical methods using a testfield of control points. The offset between the GPS antenna and the vision system is determined by a rigorous bundle- and geodetic adjustment. Beside the storage of images the vision system is used for sequential triangulation of stereo pairs along the road, to bridge over areas without satellite signals. We also try to extract the edges of roads automatically and compute its width. As the construction of the prototype is presently ongoing, preliminary results and the configuration of the hardware are presehted.
