Patent Images

1. A method for reconstructing a structure having a three-dimensional extension, comprising the stages of:

  • obtaining at least three images of the structure to be reconstructed, each of said images showing reference points which permit the determination of a matrix (T) which describes the geometric projections associated with each image;

    identifying, by means of said three images, a starting point for the tracing of a center line of an elongate element of said structure;

    tracking the center line of the elongate element to an end point;

    determining the cross-sectional dimension of said elongate element at a plurality of points of the center line;

    reconstructing the three-dimensional image of the elongate element from said cross-sectional dimensions and said center line.
