Description
Technical field
The present invention relates to augmented reality, location and field of sensing technologies, be specially a kind of augmented reality plateform system and application process of position-based mapping.
Background technology
Now main flow recreation and simulation system mainly all are based on the desktop virtual reality.Though along with the development of image technique, desktop can present picture more true to nature, the user still need be sitting in face of the computer, and only limits to carry out with equipment such as mouse, keyboard and virtual scene or other user limited mutual.This type systematic has not been used the person on user experience satisfies.Therefore immerse fully a kind of, how mutual the demand that has more recreation such as vision, the sense of hearing, sense of touch or simulation system be just more and more stronger.Augmented reality technology particularly cooperating type augmented reality technology provides possibility for the realization of this system.
Augmented reality (Augmented Reality is called for short AR) also is referred to as mixed reality, is one of research focus of external in recent years numerous well-known universities and research institution.It passes through computer technology; Virtual information is applied to real world; Be added in real time same picture or space of real environment and virtual object exists simultaneously and realized virtual information to the replenishing of real world information, stack, and its main application fields comprises medical research and dissects training, exact instrument manufacturing and maintenance, military aircraft navigation, engineering design and tele-robotic control etc.Augmented reality mainly is used for strengthening the effect of sense organ aspect such as user's vision, the sense of hearing, sense of touch, is replenishing and expansion the actual environment real information.The researchist of Canada McGill University (McGill University) develops a kind of floor tile system that imitates sand ground, snowfield, meadow environment; This system is by a series of sensors, projection, loudspeaker and can shake plate and form; Wherein, Sensor is used to receive user profile, projection, loudspeaker, can shake plate and then is respectively applied for and strengthens user's feedback aspect vision, the sense of hearing, sense of touch when stepping into varying environment.Augmented reality system such as above-mentioned combination vision, the sense of hearing, sense of touch can be brought more rich experience to the user, but can not satisfy the requirement of collaborative work and amusement.Because the fast development of internet, augmented reality and network technology combine to become possibility, in fact, the cooperating type augmented reality is exactly that one of them typical case represents.
Cooperating type augmented reality technology (Collaborative Augmented Reality; Be called for short CAR) be the combination of augmented reality technology and network technology; It is the important component part of augmented reality technology; It can make a plurality of users experience the augmented reality scene that virtual objects and true environment combine together simultaneously, and can on network communication platform, carry out various interactive operations and collaborative work, accomplishes preplanned mission jointly.The augmented reality air hockey system (AR2 Hockey) of people's research and development such as the at present existing Japanese augmented reality system laboratory Toshikazu Ohshima of cooperating type augmented reality technology, Kiyohide Satoh.This system adopts based on the nothing of user's relative position and repels mutual dynamic registration method; Two players can realize a hockey tournament through physics sports ground, mallet and the virtual hockey of sharing; Yet; Be subject to simple registration algorithm, the defective of its existence is that the participant of system need be in same true environment, and carry out crew-served user simultaneously can not be more than two people.This shows that cooperating type augmented reality technology, particularly interactive stronger distributed collaborative formula augmented reality technology are in real time, location registers has higher requirements accurately.
