Method for the localization of a tool in a workplace, corresponding system and computer program product

A method for locating a tool for industrial operations that is positioned in a sequence of operating points (L 1 ...L n ) of an operating sequence (SE) associated to different positions on a component (12) on which work is to be carried out, comprising associating a light source (ST) to said tool (11) and at least three light sources (SC 1 , SC 2 , SC 3 ) identifying a position reference triplet (RE) fixed with respect to said component (12); acquiring, via a stereovision apparatus (20) comprising at least two video cameras (21a, 21b), at least two respective images of said tool (11) and component (12); tracking (300) the displacement of said operating points (L 1 ...L n ) on said component (12), in particular when carrying out an industrial operation on the component, by: - recognizing (323) positions (PC 1 , PC 2 , PC 3 ) of the reference triplet (RE) and a point (PT) of the light source (ST) of the tool (11); - calculating (324) the position (PL 1 ...PL n ) of the operating points (L 1 ...L n ) of an operating sequence (SE) with reference to the position assumed by the reference triplet (RE); and - evaluating (325, 326) the position (PT) of the tool (PT) with respect to the calculated position (PL 1 ...PL n ) of the operating points (L 1 ...L n ).
