Augmented reality as a comparison tool in automotive industry

Augmented reality (AR) can be used in the automotive industry to compare real parts of a car with their associated construction data. The real parts have to be checked whether they correspond to the latest version of the design and whether they have been manufactured with appropriate precision. With AR, CAD construction data can be superimposed on the real parts striving for maximum correspondence. The real and the virtual part should both be visible at the same time and in the same place. Therefore, for this kind of overlay, a special method of augmentation is needed. We present and discuss some visualization schemes.
