Method and apparatus for measuring the dimensions and characteristic angles of wheels, steering system and chassis of vehicles

An apparatus for measuring the dimensions and characteristic angles of the wheels, steering system and chassis of vehicles, comprising a plurality of 3D scanners, functionally connected to a computer;

• each one of said 3D scanners having a viewing field, the merging of said viewing fields defining a viewing field of the apparatus;
• said 3D scanners being arranged peripherally to a vehicle being measured so that all the wheels of said vehicle are at least partially visible in the viewing field of the apparatus, when said vehicle is in a total measurement position;
• said computer and said 3D scanners being configured to perform a measurement when all the wheels of the vehicle are at least partially visible in the viewing field of the apparatus and a measurement when the vehicle is in a partial measurement position in which at least one wheel is not visible in the viewing field of the apparatus;
• said apparatus being wherein said 3D scanners are fixed with respect to each other and to a support of the vehicle, between said total measurement step and said partial measurement step.
