Abstract: Systems, methods, and computer-readable storage media for constructing and using a model for tracking an object are disclosed. The model may be constructed from a plurality of images and a coordinate system defined with respect to the pedestal upon which the object is placed, where the plurality of images correspond to images of the object while the object is placed on a pedestal, and where the pedestal includes a plurality of markers. The model for tracking the object may be configured to provide information representative of a camera position during tracking of the object using a camera. Tracking the object using the model may include obtaining one or more images of the object using a camera, and determining a position of the camera relative to the object based on the model.
