Virtual information`s data model determining method, involves transforming extracted edge extracted from respective view to three-dimensional contour model corresponding to data model

摘要

The method involves providing a three-dimensional computer aided design (CAD) model for representing a real object. Different synthetic two-dimensional views (31-34) of the CAD model are generated. Each generated view is subjected to edge extraction for determining an extracted edge in a respective view. The extracted edge extracted from the respective view is transformed to a three-dimensional contour model corresponding to a data model. Independent claims are also included for the following: (1) an object tracking method (2) a system for determining a data model of virtual information, comprising a unit for providing a three-dimensional computer aided design (CAD) model (3) a computer program product comprising a set of instructions for performing a method of determining a data model of virtual information.
