Abstract: A method for measuring the dimensions and characteristic angles of wheels, steering system and chassis of vehicles by means of an apparatus comprising a plurality of 3D scanners, functionally connected to a computer and arranged peripherally to a vehicle whose dimensions and characteristic angles of wheels, steering system and chassis are to be measured; each one of the 3D scanners having a viewing field, the merging of the viewing fields defining a viewing field of the apparatus; the method is characterized in that it comprises: a total measurement step, in which all the wheels of the vehicle are at least partially visible in the viewing field of the apparatus; and a partial measurement step, in which at least one wheel of the vehicle is not visible in the viewing field of the apparatus.

Abstract: A vehicle equipment comprises a scanning system for the contactless measurement of at least one projector arranged at least for the projection onto an object to be measured of a structured light with a pattern, at least one video camera arranged for the acquisition of the image of the object to be measured, and a processing unit for processing the acquired image for the three-dimensional reconstruction of the object to be measured, the projector comprising in turn at least one matrix of emitters integrated into a monolithic substrate.

Abstract: Equipment for determining at least one value of at least one parameter characteristic of one or more vehicle component in the scope of a diagnostic, maintenance or monitoring operation, includes at least one time-of-flight sensor for acquiring information relative to the shape and size of the component, and a first processing unit operatively connected to the time-of-flight sensors for receiving acquired data from the latter, so as to be able to calculate the value assumed by the characteristic parameter. The time-of-flight sensor includes an emitter of waves incident on the component of the vehicle, a receiver of the incident waves reflected by the component, and a second processing unit suitable for measuring phase displacements sustained by the waves following the incidence on the component, and for calculating, on the basis of the phase displacements, the distance from the sensor of the points of the component on which the waves impact.

Abstract: Alignment device adapted to measure characteristic angles of the wheels and of the steering of motor vehicles, particularly camber, toe-in, caster, by way of arms provided with sensors to be fastened to the wheels. In particular, in the step for determining the mounting error of the grip elements (runout), the level sensor is used to measure the wheel rotation angle and methods for compensating the measurements performed when the arms are at a nonzero level are then applied.
