1. A method for controlling the deposition of elementary semifinished products in a process for building a tyre for vehicle wheels, comprising:

  • driving in rotation a tyre being processed around a rotation axis at a rotation speed between about π

    /8 rad/s and about 6π

    rad/s, said tyre having a radially external surface comprising one or more elementary semifinished products;

    sending a first electromagnetic radiation to said radially external surface, the radially external surface generating a corresponding first reflected radiation;

    detecting, through a first detecting device, at least one first image representative of said first reflected radiation, wherein the at least one first image is obtained by a detecting window substantially parallel to the rotation axis of said tyre being processed;

    controlling said first detecting device in such a manner that a first exposure time for detecting said at least one first image is between about 0.1 s and about 10 s;

    carrying out a first comparison between said at least one first image and one or more reference data; and

    generating a first notification signal as a function of said first comparison.
