METHOD OF DETERMINING A GEOMETRICAL TRANSFORMATION BETWEEN TWO MODELS OF A THREE-DIMENSIONAL OBJECT

摘要

The invention relates to a method of determining a geometrical transformation between a first model of a three-dimensional object and a second model of the three-dimensional object, said first model being obtained on the basis of a first measurement instrument, said method comprising: a first step (E1) of defining the second model; a second step of defining at least one invariant reference point between the first model and the second model; a third step (E3) of slicing the first model and the second model with respect to said invariant reference point, said first model being sliced into a first cloud of points, said second model being sliced into a second cloud of points; and a fourth step (301) of determining the geometrical transformation between the first cloud of points and the second cloud of points.
