Abstract
Disclosed is a computer-implemented method for registering a first and a second three-dimensional digital structure. The first and second three-dimensional digital structures are received. First structural features of the first three-dimensional digital structure and second structural features of the second three-dimensional digital structure are determined. A first plurality of first feature sets of first structural features and a second plurality of second feature sets of second structural features are defined. Pairs of first and second feature sets describing first and second n-gons satisfying a congruence criterion are identified. To each pair of first and second feature set a point in a transformation space is assigned. A rigid spatial transformation for registering the first three-dimensional digital structure with the second three-dimensional digital structure is determined using a clustering of the points assigned in the transformation space. The first and second three-dimensional digital structure are registered using the determined rigid spatial transformation.
