Method and device for determining the alignment of the wheels of a vehicle

摘要

Method for determining the angles and the characteristic parameters of the alignment of a vehicle situated at a measurement location comprising the following steps: equipping each of the wheels of the vehicle with a flat target carrying any design; determining the relationship between the position of the target and the wheel; arranging at least one pair of television cameras making a stereo system in a position such as to see at least the target associated with a wheel; creating a spatial reference system W to which the three-dimensional image of the target created by said at least one pair of television cameras refers; processing the three-dimensional image of the target collected by the two television cameras and determining the angular orientation and the position of the target in the spatial reference system W; using said position and angular orientation to determine the alignment of the wheel relative to the spatial reference system.
