Vehicle equipment with scanning system for contactless measurement

A vehicle equipment measuring the characteristic dimensions and/or angles of wheels, steering and chassis of vehicles in a wheel alignment device, comprising:

• a scanning system for contactless measurement equipped with at least two video cameras and at least one projector, the at least one projector arranged at least for the projection onto an object to be measured of a structured light with a pattern, and includes at least one matrix of emitters integrated into a monolithic substrate and a device changing the projected patterns, and
• wherein the at least two video cameras are arranged for the acquisition of at least two images of the object showing that the pattern is projected onto the object, and
• a processing unit configured to compute a plurality of three-dimensional reconstructions of the object to be measured, each of said three-dimensional reconstructions of the plurality of three-dimensional reconstructions is computed without a prior knowledge of the geometry of said pattern, from at least two images of the object showing that the pattern is projected onto the object, the pattern being changed between at least two three-dimensional reconstructions of the plurality of three-dimensional reconstructions, said processing unit further configured to compute a plurality of measurements of the object from the plurality of three-dimensional reconstructions and to mediate the measurements of the plurality of three-dimensional reconstructions to obtain a mediate measure of the object.
