Abstract:
A method of registering data, the method comprising the steps of:receiving reference independent three-dimensional data representing an object, wherein the reference independent data includes a plurality of three-dimensional frames F1 through Fn, where n is a positive integer greater than 1, and each of the frames F1 through Fn represent a three-dimensional representation of a portion of the object and wherein there is no prior knowledge of the spatial relationship of said frames F1 to Fn to each other due to the data being reference independent; and performing a first registration of said frames F1 to Fn to create a first three-dimensional model of the object; and performing a second registration of said frames F1 to Fn to create a second three-dimensional model of the object; wherein the step of performing the first registration attempts to register each frame to one other frame, and wherein the second registration attempts to register frames to a cumulative model formed from previously registered frames.
