Claim 0:
1. A method of registering a luminal network to a 3D model of the luminal network, the method comprising:
identifying a first region of the luminal network and a second region of the luminal network;
receiving location data associated with a location sensor on a tool navigating the luminal network;
identifying a plurality of potential matches in the 3D model from the location data;
assigning at least one of the potential matches a registration score based on a deformation model applied to the 3D model, the deformation model including applying a moving window from the first region to the second region of the luminal network, and performing a rigid registration in the moving window; and
displaying a potential match of the plurality of potential matches having a highest registration score.
