Abstract: In a method for measuring the wing edge of a vehicle on a test bed, the test bed has a coordinate system in which the Z-axis is the vertical axis, the X-axis is an axis on the test bed extending in the horizontal plane in the longitudinal direction of a vehicle located on the test bed for testing, and the Y-axis is an axis of the test bed extending perpendicular to the X-axis in the horizontal plane. In determining the position and orientation of the wing edge, a light pattern projected onto a vehicle by an illumination unit is moved and recorded by two imaging units. A subset for evaluation is formed from the 3D point clouds determined stereophotogrammetrically from the recordings.
