Abstract:
A method of registering data, the method comprising the steps of:receiving reference independent data representing an object, wherein the reference independent data includes a plurality of 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 obtained from a scanning the object with a scanner 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 registration between frame Fx and frame Fx+1, where x is an integer between 1 and nâˆ’1; wherein the step of registration further includes the sub-step of: determining a registration entry point between the portions of frame Fx and frame Fx+1; wherein: each of the plurality of frames is derived from a two-dimensional representation; and wherein the step of determining a registration entry point further includes the step of determining the entry point at least partially based upon a two-dimensional analysis of the said two-dimensional representations of the frames Fx and Fxâˆ’1.
