Description
Technical field
The present invention relates to a kind of intelligent mobile phone enhancement system and implementation method based on three-dimensional electronic compass.
Background technology
Augmented reality (AR, Augmented Reality), usually being also referred to as and expanding reality, enhancing vision or augmented reality vision, is the new research direction that development is come out on the basis of virtual reality research in the world in recent years, also is a difficult point hot issue of virtual reality research field.The augmented reality technology be exactly virtual image that computer is generated or other information organically, in real time, dynamically stack (or fusion) is in the middle of the actual environment that the observer saw, and the actual environment around these virtual informations and the user combines together, make the user be sure of that from sensory effects virtual environment is its organic component of true environment on every side, when the user is mobile in real scene, dummy object also changes thereupon, just look like these dummy objects be really be present in the real scene the same.This enhancing information can be the dummy object that coexists with real-world object in true environment, also can be the non-geological information about the real-world object that exists.From the present situation that develops both at home and abroad at present, the augmented reality system still is in laboratory stage, and the tracking registration technology of having succeeded in developing at present generally need just can be obtained accurate result under the condition of ambient controlled.With respect to the development of indoor augmented reality system, the development of outdoor augmented reality system relatively lags behind.
Virtual image to be superimposed upon on the scene of objective world exactly, just must determine user's position and direction of visual lines accurately, in real time.For outdoor augmented reality system, the method for tracking and positioning that adopts usually in the world mainly divides three classes at present: based on the registration location of computer vision, based on the registration location of tracking equipment, based on the mixing registration location of vision and tracking equipment.Based on the three-dimensional register method of computer vision based on theory on computer vision, the actual environment image that ccd video camera photographs is handled and discerned, obtain trace information, the equipment that is characterized in is simple, with low cost, at present the research based on the registration technology of computer vision is in leading position in the AR field.But, adopt the logon mode of computer vision also improper on a large scale for unknown outdoor environment.Based on the logon mode of tracking equipment, its location tracking equipment comprises GPS (Global Position System) (GPS), inertial navigation system (INS), three-dimensional electronic compass, accelerometer, inclinometer or the like.Because each tracer technique respectively has length, for outdoor AR system, also can satisfy its harsh requirement fully at present without any a kind of performance of tracking technique.Therefore, the final method that Welch (2002) and Azuma people such as (1998) have proposed to address this problem is to adopt to mix (hybrid) tracking technique, promptly by merging multiple tracer technique, learn from other's strong points to offset one's weaknesses, obtain comparatively accurate, reliable tracking results, but meanwhile also increased complexity, operand and the cost of system.At present, mainly there is following problem in the outdoor augmented reality system based on wearable computer or portable computer:
1, equipment heaviness, the user bears a heavy burden greatly, carries inconvenience;
2, system is owing to the restriction that is subjected to carrying power supply, and system's duration is short;
3, complete set of equipments cost height.
Though can realize the miniaturization, portable of outdoor augmented reality system being difficult to adopt the combined tracking technology based on the augmented reality system of portable terminal, mainly have following problem at present owing to be subjected to the restriction of hardware condition:
Though 1, smart mobile phone or PDA have built-in GPS and can position, owing to there is not integrated three-dimensional electronic compass, can't determine the direction of sight line, therefore just can't set up the intelligent mobile phone enhancement system;
2, some mobile phone the is integrated chip of electronic compass, but these mobile phones are not smart mobile phones generally, are difficult to carry out software development again and realize the augmented reality function, and what these mobile phones were integrated in addition generally all is two-dimentional electronic compass, the azimuth can only be provided, can't satisfy the requirement of augmented reality.
Progressively open develop rapidly with the mobile communication cause along with China's 3G network, people are to the 4A (Anytime of geospatial information, Anywhere, Anybody, Anything) Fu Wu demand manifests day by day, portable terminal combines with spatial Information Service, spatial orientation information service (LBS) occurred, thus the information service relevant that provides the user to need with the position.Augmented reality technology and LBS combine the information that can realize in real time, mutual, dynamically, three-dimensional display, for example can smart mobile phone real time inspection underground pipe network, the literal annotation information can be superimposed upon in real time and build on the thing or the like.Use the user of smart mobile phone also increasing year by year among the huge cellphone subscriber group of China, some is not necessarily very accurate for the positional information requirement in these high-end users, the precision of meter level or sub-meter grade just can meet the demands, and therefore adopts the augmented reality system based on smart mobile phone just to have very big application potential.
