Claim 16:
17. Optical scanning system for measuring and/or controlling a vehicle and/or parts of a vehicle, where the vehicle is arranged on a control station, the optical scanning system comprises:
at least two optical reader apparatus which are arranged on a plane (P) of said control station, on opposite sides of the longitudinal axis (A) of said vehicle, in order to be facing to the opposite lateral sides of the vehicle,
the two optical reader apparatus are provided with respective optical image capturing devices configured to provide respective data/signals encoding one or more images containing at least partially said opposite sides of the vehicle,
an electronic processing and control system which is configured to process said data/signals in order to determine and construct one or more three-dimensional images relating to said vehicle and/or to parts of the vehicle,, said optical reader apparatuses each comprise:
a plate-shaped element which extends along a longitudinal axis (C) transversal to said longitudinal axis (A) and is fixed on said plane (P) in a position adjacent to one side of the vehicle, said plate-shaped element has a horizontal upper surface on which a fixed horizontal calibration target is arranged adjacent to the optical image capturing device of the relative optical reader apparatus at a predetermined distance from it,
said optical image capturing devices is configured to capture one or more images of said fixed horizontal calibration target on said plate-shaped element so as to provide respective data/signals encoding the image of the fixed horizontal calibration target itself,
said electronic processing and control system is configured to calibrate said optical reader apparatuses on the basis of the images of the respective fixed horizontal calibration targets.
