摘要
A method for real-time and inserting a virtual object within a virtual scene from a physical object, including dynamically perform the following actions: - capture from a physical camera an image of a physical object against a background; - extracting a silhouette of said physical object of the captured image and the captured image mapped on a three-dimensional geometry obtaining a virtual object; - incorporating said virtual object as an element in the virtual scene; and - orienting said virtual object from a virtual camera in order to prevent said virtual object is present on edge, it characterized in that the method further includes: - obtaining and using intrinsic and extrinsic parameters of said physical camera and said captured image physical object to calculate a position of said physical object, and determining a position of said virtual object by calculating at least the coordinates of the lowest point of said physical object captured from said image against said background; - place the virtual object on said calculated said physical object within the virtual scene and selecting a rotation axis to orient the virtual object from the virtual camera based on said calculated physical object position; and - reprojects said captured image on the three-dimensional geometry using these intrinsic and extrinsic parameters of physical camera.
