Abstract

A method for checking the referencing of at least two measuring heads of a contactless chassis measuring system includes: detecting at least one geometry detail of a vehicle using the measuring heads; determining an initial position of the geometry detail in the coordinate system associated with each measuring head; transforming the initial position into a shared coordinate system; executing a relative movement between the measuring heads and the vehicle; determining a final position of the at least one geometry detail in the coordinate system associated with each measuring head; transforming the final position of the geometry detail into the shared coordinate system; determining the movement vectors from the difference between the final position and the initial position of the at least one geometry detail; checking the movement vectors for coincidence.
