Method for 3D/2D registration using multiple views and a surface model of an object

摘要

A method for the direct registration, of two or more 2D optical images to a 3-dimensional (3D) image or computer model without prior segmentation of images is by acquiring a plurality of optical images of the object and acquiring a three dimensional surface model made up of points on a surface of the object, choosing an initial set of parameters which define the registration between the three dimensional model coordinate system and the optical image coordinate system, measuring the quality of registration using a similarity measure and repeating until a maximum of the similarity measure is found.
