<p>Optoelectronic method for measuring the dimensions and shapes of fruits, vegetables and various objects, characterised in that the product to be classified is passed at a constant speed in front of an assembly comprising a frame 1 fitted, on one of its sides, with a set of photodiodes 5 situated in planes at various heights defining and determining a detection unit 7, the opposite side having a series of orifices 3 positioned from top to bottom facing the photodiodes and coinciding with them, while the beam of rays from one or more light sources 2 incorporated into the system is projected horizontally and parallel and encounters the bank of photodiodes, which is fitted with the electronic circuits necessary for transmitting the signals which it detects to a logic circuit of a microcomputer which, by mathematical calculations, determines the maximum, minimum and mean diameters or any other variable relating to the dimensions and shape of the product to be classified. <IMAGE></p> |
