Abstract
Apparatus and methods that track the location of an object within a video image at the time of capture of the video image are described. The location of the object within each frame can be recorded as meta-data for the video image so that when the video image is played back, a viewer can select the object using suitable interaction means and be linked through to a source of additional information about the object, such as a product website or the like. A device emitting radio frequency (RF) signals is attached to an object that is to be identified and tracked within a video image. Using an RF receiver with multiple antennas and applying trilateration techniques, the object's location within the video image is determined in real time and recorded as the video image is recorded. Where multiple objects are to be tracked, each object is provided with a radio device having a unique ID and the location of each device within the video image is recorded. The described solution automates an otherwise manual, error-prone and time-consuming process.
