1. A method for locating a tool for industrial operations that is positioned in a sequence of operating points of an operating sequence associated to different positions on a component on which work is to be carried out, comprising: associating a light source to said tool and at least three light sources identifying a position reference triplet fixed with respect to said component, acquiring, via a stereovision apparatus comprising at least two video cameras, at least two respective images of said tool and component; tracking the displacement of said operating points on said component, when an industrial operation is being carried out on the component, by: recognizing positions of the reference triplet and a point of the light source of the tool; calculating the position of the operating points of an operating sequence with reference to the position assumed by the reference triplet; and evaluating the position of the tool with respect to the calculated position of the operating points.
