Research And Application Of Augmented Reality Based On IPhone

With the rapid development of information technology and related technology such as computer vision research and innovation,application platform for mobile devices in the augmented reality become a research focus of scholars at home and abroad.Superior running speed,high integration of hardware and software,and is convenient to use smart phone is a representative of the mobile devices,also is the natural platform for the mobile augmented reality application.Mobile augmented reality has a strong sense of reality,modeling,safe and reliable,the advantages of small amount of work has been in the education,cultural relic reconstruction,business development and application,medical and other fields.Because only in traditional Chinese medicine acupuncture learning through multimedia presentation make fine details of the knowledge lack of accuracy,and the learning time is short.So this article use mobile augmented reality on iPhone auricular acupuncture tutorship system,the system through the 3d model rendering,tracking the registration,the actual fusion process realizes the virtual reality fusion scene display of the ear model.The main research content is as follows:1.Based on the research of the theory and technology of augmented reality principle,analyzed the characteristics of the mobile augmented reality application to extract,tracking,key technologies,such as registration,the actual fusion in the acupuncture learning MAR system,combining with the advantages and disadvantages of the mobile device to the above key techniques are studied and improved,the final guarantee system enhancement showed a seamless and high fidelity between virtual integration scenarios.2.Real-time and functional requirements of the system,detailed analysis of SIFT,SURF,ORB algorithm,on the basis of this proposed using an improved algorithm of the ORB set the total number of feature points and nearest neighbor distance.The experimental results show that the method in resource-constrained mobile devices between virtual integration scenarios can provide stable and reliable,can meet the real-time mobile augmented reality system.3.Theory and technology of matching algorithm is studied,in order to solve the influence of noise and light,using median filter for removing noise and histogram equalization,and adopt the way of combination of coarse and fine match to ensure theaccuracy of the system matching.the system for 3D model using Sketch Up and in the way of OBJ file to import.The experimental results show that the system can be finished and meet the real-time demand of mobile augmented reality.
