Abstract

Changes in the shape of cars due to impact in crash tests are determined from the deformation vectors of points located in specific positions on the car. The coordinates of these points are measured before as well as after the test. Costs and measurement time can be significantly reduced by automated dimensional inspection with digital photogrammetry. This paper reports on a pilot test in which the measurement of a car prepared for a crash test was performed under practical conditions. It was shown that an accuracy of 1 mm in each coordinate axis within a measurement volume of 5 X 2 X 2 m3 can be achieved under factory- floor conditions with low-cost CCD cameras. A high level of automation and robustness was demonstrated. The measurements were performed in a very short time with model-driven techniques.
