The concept of a mobile mapping workstation is described. The workstation integrates a stereo-vision system, a GPS-receiver, and an inertial system, to automatically collect data of the environment of roads at highway speeds and store this information in a GIS. The vision system acquires and stores digital image-pairs once a second. Three dimensional coordinates can be computed by intersection of image points and related to a global coordinate system by means of the GPS antenna. The analytical calibration of all sensors of the workstation, the automatic detection of the edges of the road and a sequential triangulation of stereo-pairs is discussed.
