The 4-D approach to real-time machine vision presented in the companion paper (Dickmanns and Graefe 1988, this volume) is applied here to two problem areas of widespread interest in robotics. Following a discussion of the vision hardware sed, first, the precise position control for planar docking between 3-D vehicles is discussed; second, the application to high speed road vehicle guidance is demonstrated. With the 5 ton test vehicle VaMoRs, speeds up to 96 km/h (limited by the speed capability of the basic vehicle) have been reached. The test run available, of more than 20 km length, has been driven autonomously several times under various weather conditions.
