摘要
A system for, and method of, extracting a surface profile from a stereo pair of images obtained at an arbitrary setting S of an optical system, includes determining surface profile reconstruction parameters for images obtained with the optical system at a reference setting So of the optical system; determining warping parameters for a digital image processor for warping images obtained with the optical system at the arbitrary setting S into images corresponding to the reference setting So; obtaining the stereo pair of images from at least one camera of the optical system; warping the stereo pair of images into images corresponding to the reference setting So, and using the surface profile reconstruction parameters to determine the surface profile. In a particular embodiment, the surface profile is passed to a computer model of tissue deformation and used to determine an intra-surgery location of a tumor or other anatomic feature of tissue.
