A method of tracking objects that allows objects to be tracked across multiple scene changes, with different camera positions, without losing track of the selected object.In one embodiment, a method of tracking an object using a computer, a display device, a camera, and a camera tracking device, the computer being coupled to the display device, the camera and the camera tracking device is disclosed. The method includes: A first image from within a field-of-view of the camera is captured. The first image, which includes an actual object with a tracking device, is displayed on the display device. Information about the tracking device's location is received. The information is used to create a virtual world reflecting the actual object's position within the field-of-view of the camera as a shape in the virtual world. Information about the camera tracking device is received. A virtual-camera position in the virtual world is created. A 3D graphics pipeline is used to create a second image, the second image presenting the shape in the virtual world. The second image is used to obtain the actual object's position.In another embodiment, the method includes using the virtual-camera's position to compute a new position for the camera to track the actual object. |
