1. An apparatus for geometric measurement and inspection of wheeled vehicles, comprising:
- plural measuring heads adapted to be fixed to wheels of the vehicle being inspected, for determining the physical parameters representative of an individual geometric position of a first wheel relative to a vertical plane or relative to a horizontal plane, and physical parameters representative of relative geometric positions of the first wheel relative to a second wheel of the vehicle being inspected;
a first source of luminous emission fixed to the first wheel and adapted for emitting at least one first substantially horizontal light ray;
a second source of luminous emission fixed to the second wheel and adapted for emitting at least one second substantially horizontal light ray; and
at least one means for forming images of said first and second sources of luminous emission on a first optical linear detector fixed to a third wheel of the vehicle being inspected, said first optical linear detector being adapted for receiving the at least one first and second substantially horizontal light rays from said first and second sources of luminous emission respectively.

Abstract
A device for geometric measurement and inspection of wheeled vehicles includes structure for determining physical parameters usable for computation of the angles and distances characteristic of the vehicles to be inspected. Each device for determining a physical parameter includes at least one substantially horizontal light beam emitted by a light source, at least one image forming device of this source on an optical linear detector, and at least one optical linear detector, preferably of the CCD or PSD type, adapted to receive at least two substantially horizontal light beams from at least two separate sources.
