Abstract
A method for a computer system includes receiving a first camera image of a 3D object having sensor markers, captured from a first location, at a first instance, receiving a second camera image of the 3D object from a second location, at a different instance, determining points from the first camera image representing sensor markers of the 3D object, determining points from the second camera image representing sensor markers of the 3D object, determining approximate correspondence between points from the first camera image and points from the second camera image, determining approximate 3D locations some sensor markers of the 3D object, and rendering an image including the 3D object in response to the approximate 3D locations.
