| Augmented Reality is a new research field of internationally in recentyears,the purpose of which is fusion the virtual information generated bythe computer and the real world to enhance the user’s visualfeeling,making the interaction of users and real world more intuitive, morerealistic.The development status at home and abroad shows that, it hasvast development foreground in mobile phone platform.This paper firstly studyed the augmented reality display technologyand3D registration technology, introduced the display device, andanalysised the advantages and disadvantages of various equipments. Thearticle detailed analysised various registration algorithms, Put forward themethod of using two-dimensional code as the marker to marking theinterior of the building,analying the process of registration based on thevisual marker, then the3D registration algorithm is derived in detail,Getting the conversion of the camera coordinate system, coordinate system,marker virtual information coordinate system and2D imaging plane. For the case of the end of intelligent mobile phone performancebelow the intelligent mobile phone, this paper optimizationed algorithm byimproving the registration accuracy and reducing the amount ofcomputation. Common least square method to solve the camera parameters,didn’t take into account the parameters between the independence,so thereis a big error and has large amount of calculation. In order to improve theregistration accuracy and reduce the amount of calculation, the paper usedthe method of least squares calculation parameters of camera, introducedthe rotation matrix orthogonality constraints. The method not onlyimproves the registration accuracy, but also effectively reduces thecomputation of the system, improve the registration performance.Finally, designed and implementation the augmented reality systemfor indoor wizard, and tested it in the Android terminal intelligent mobilephone. The test results showed that the system is applicable to terminalintelligent mobile phone, and realized the function of user real-timepositioned and indoor wizard. |
