Abstract (en)

[origin: EP0620051A1] The invention relates to a method for automatic colorimetric sorting of products, such as fruit or vegetables, in which each product is illuminated by means of a beam embodying a succession of luminous streaks, the energy returned by the product in preselected wavelengths is recovered for each point of each luminous streak, the luminous intensity of each point is measured, the measured values are converted so as to form numerical data strings corresponding, for each wavelength, to the luminous intensity curves of each luminous streak, and the numerical data strings are computationally processed by comparing the values of the counterpart points in the said strings, so as to generate an exploitable colorimetric information item. <IMAGE>
