Реферат: Methods, systems, and computer-readable media for registering electromagnetic navigation data of a luminal network to a 3D model of the luminal network includes accessing a 3D model of a luminal network based on computed tomographic (CT) images of the luminal network, the 3D model corresponding to a CT coordinate space, selecting a plurality of reference points within the 3D model of the luminal network, accessing a plurality of survey points within the luminal network, the plurality of survey points being based on electromagnetic navigation data and corresponding to a body coordinate space, correlating the plurality of reference points and the plurality of survey points to determine pairs of correlated reference points and survey points; and deriving a transformation that maps the body coordinate space to the CT coordinate space based on the pairs of correlated reference points and survey points.
