ABSTRACT:
A method for obtaining three-dimensional surface points of an object in an object coordinate system having two groups of steps. The method includes providing a set of target positioning features on the object. In a first group of steps, acquiring 2D first images of the object, extracting 2D positioning features; calculating a first set of calculated 3D positioning features; computing first transformation parameters, cumulating the first set of transformed 3D positioning features to provide and augment the set of reference 3D positioning features. In a second group of steps, providing a projected pattern on a surface of the object; acquiring 2D second images of the object, extracting 2D surface points and second sets of 2D positioning features; calculating a set of 3D surface points; calculating a second set of calculated 3D positioning features; computing second transformation parameters, transforming the 3D surface points into transformed 3D surface points.
