Abstract
A method of obtaining a three-dimensional digital model of an artificial object, made up of a plurality of geometric primitives, the artificial object being in a single two-dimensional photograph, the method comprising: using edge detection to define a two-dimensional outline of the artificial object within the photograph; interactively allowing a user to define two-dimensional profiles of successive ones of the geometric primitives; interactively allowing a user to sweep respective profiles over an extent of a corresponding one of the geometric primitives within the image; generating successive three-dimensional model parts from existing detected edges of the corresponding geometric primitives and the sweeping of the respective profile; and aligning the plurality of three-dimensional model parts to form the three-dimensional model.
