1. A system comprising:
a spray boom provided with a plurality of spray nozzles supplied by a spray control device;
a set of cameras capable of capturing images of an area to be treated;
a memory in which mapping data relating to mapping between a camera reference system and a spraying reference system is stored;
a digital processing device capable of analyzing the images captured by the camera, identifying plants to be treated and applying commands to the spray control device to selectively spray a product on plants to be treated; the digital processing device being capable, on the basis of said mapping data, of applying, to the images captured by each camera, subdivision data for subdividing the image into cells corresponding to spray areas on the ground that are to be sprayed by respective spray nozzles, in order to thereby directly determine, from said subdivision data, at least one nozzle to be activated and its activation time when a plant to be treated is identified in a given cell of the image; and
a device for dynamically determining at least one geometric parameter of each camera relative to the ground and for dynamically adjusting the subdivision data according to variations in the geometric parameter or parameters.
