Patent ID: RE43952

Claim:
An interactive system for local intervention inside a region of a non-homogeneous structure to which is connected a reference structure containing a plurality of base points, the interactive system comprising: means for dynamically displaying a three-dimensional image of a representation of the non-homogeneous structure and of the reference structure connected to the non-homogeneous structure, wherein the three-dimensional image also includes a plurality of images of the plurality of base points; means for determining a set of coordinates of the plurality of images of the plurality of base points in a first reference frame; means for fixing a position of the non-homogeneous structure and of the reference structure with respect to a second reference frame; means for determining a set of coordinates of the plurality of base points in the second reference frame; means of intervention comprising an active member whose position is determined with respect to the second reference frame; means for generating a plurality of reference frame translation tools for translating a plurality of reference frames from the first reference frame to the second reference frame and vice versa, based on the set of coordinates of the plurality of images of the plurality of base points in the first reference frame and of the set of coordinates of the plurality of base points in the second reference frame, in such a way as to reduce to a minimum at least one of a set of deviations between the set of coordinates of the plurality of images of the plurality of base points in the first reference frame and the set of coordinates of the base points, expressed in the first reference frame using the plurality of reference frame translation tools; means for defining, with respect to the first reference frame, a simulated origin of intervention and a simulated direction of intervention; and, means for transferring the plurality of reference frames using the plurality of reference frame translation tools to establish a bidirectional coupling between the simulated origin of intervention and the simulated direction of intervention and the position of the active member.
