Abstract

The invention relates to a method for controlling a vehicle washing installation with the use of a light-section procedure, wherein at least one treatment device (1) and a vehicle (2) to be washed are moved relative to each other in the washing direction (L), the vehicle surfaces are illuminated by two light fans (11, 12) starting from different positions, a first (FIG. 7) and a second (FIG. 8) two-dimensional depiction of the vehicle surfaces illuminated by the light fans (11, 12) are recorded from shooting angles which are oblique with respect to the planes of the light fans, and are stored in a control unit (20) together with the relative position and/or relative movement of treatment devices (1) and vehicle (2), the preceding steps are repeated during a traversing operation from one end to the other end of the vehicle (2), and, during or after the end of the traversing operation, a three-dimensional representation of the vehicle surfaces is calculated from the two-dimensional depictions (FIG. 7, FIG. 8) stored in the control unit (20), and from the shooting angles, the relative position and/or relative movement and position data of the light fans (11, 12), and said three-dimensional representation is used in order to control the vehicle washing installation, in particular the treatment devices (1) arranged thereon.
