Accord-ing to the usage, camera tracking can be divided into two catalogs, which are specialhardware based puter vision based approaches. Computer vision based meth-ods currently suffers putational cost, which makes it only gets good resultwhen calculated off-line, so that it is basically used in accuracy preferred in the ef?ciency preferred real-time applications, like augmented reality, peopleuse special hardware to do the tracking, like ic equipments, these approacheshave a h
