1. A method comprising:
aligning a first minimum bounding box of a three-dimensional (3D) object model with a second minimum bounding box of a scan;
determining a deformation between the 3D object model and the scan based on whether a first overlap score of the alignment meets an alignment verification threshold that is at least 75% by comparing the first overlap score with the alignment verification threshold;
when the alignment verification threshold is not met by the first overlap score, performing a random registration to produce a second overlap score; and
determining whether the second overlap score meets the alignment verification threshold by comparing the second overlap score with the alignment verification threshold.
