A method of updating a model of a luminal network. The method includes performing first imaging of a target, generating 3D image data including locations of fiducial markers using images captured in the first imaging, performing second imaging of the target from a first viewpoint and a second viewpoint, generating 2D image data including locations of the fiducial markers from the first viewpoint and the second viewpoint using images captured in the second imaging, determining locations of the fiducial markers in 3D space according to locations of the fiducial markers within the 2D image data of the first viewpoint, locations of the fiducial markers within the 2D image data of the second viewpoint, and the known angle, and registering the 3D image data generated using images captured in the first imaging with the determined locations of the fiducial markers in 3D space. The first viewpoint and the second viewpoint are oriented at a known angle relative to each other. |
