A METHOD FOR OBTAINING AND INSERTING IN REAL TIME A VIRTUAL OBJECT WITHIN A VIRTUAL SCENE FROM A PHYSICAL OBJECT

摘要

The method comprises capturing by at least a camera an image of a physical object against a background; extracting a silhouette of said physical object from the captured image and mapping it over a three dimensional geometry; incorporating said virtual object as one more element in the virtual scene; and orienting said virtual object with regard to the virtual camera. Embodiments of the method further comprises obtaining and using intrinsic and/or extrinsic parameters of said physical camera and said captured image to calculate said physical object position; projecting back said captured image over the three dimensional geometry using said intrinsic and/or extrinsic parameters; and placing the virtual object in the virtual scene and selecting an axis of rotation to orient the virtual object with regard to the virtual camera based on said calculated position of the physical object.
