During the development of vehicles body-shapes with the lowest possible air-resistance are the goal of wind-tunnel experimentation. Aerodynamic features are invetigated and body-shapes are geometrically measured in order on the one hand, to document current vehicle geometry, whilst on the other, providing data on body-shape to facilitate numerical streamlining and body-shape optimisation. Photogrammetry has opened up the possibility of rapide and extensive geometrical measurement of vehicles in the wind-tunnel. The basis for this measurement method is a new approach multiple-image-matching which enables analysis on a digital basis. Employing this algorithm a new measure- ment system with great industrial potential is being developed. For the first time in the course of this project high resolution CCD-sensors with up to 7 million pixels per image for photogrammetric on-line-imaging are being used.
