Based On Augmented Reality Technology To Realize The Display Of Model

The Augmented Reality(AR)system is a complete system that combines virtual objects with real-world scenes.The traditional AR systems are implemented using PCs or servers.The current augmented reality systems mostly use handheld terminal platforms.Because handheld mobile augmented reality(MAR)systems are more portable and practical,MAR can Android system and IOS system run for the hardware platform of the operating system,so it also increases the penetration rate of the AR system and adapts to the changing environment.With the advent of 4G and 5G,the information transfer rate between the mobile phone and the server is also improved.The great improvement has promoted the emergence and development of handheld augmented reality systems.After that,the augmented reality system can be processed on the server and then transmitted back to the handheld terminal display.Through the understanding of the augmented reality system and various aspects of reading and understanding,using the Android and IOS system hardware platforms that are now widely used to implement the AR system,not only can have good hardware and software support,but also can better promote augmented reality With the further development of technology,this article implements the AR system on the Android platform and innovates and studies the following aspects:1.Based on the analysis of common feature algorithms,a new AR system implementation method is proposed for smart handheld terminal platforms.2.The two algorithms BRSK and SURF are used together to exploit the multi-scale spatial representation of BRISK and the rotation-invariant nature of SURF.Research shows that both algorithms have a very good effect when detecting blurred images.3.After matching,tracking and registration,feature points are matched,purified and tracked by BFMatcher,distance method and LK algorithm.After verification,the stability of the system in feature extraction and matching is improved.Accuracy.4.With Android as the operating system platform,the new AR system was implemented.The environment for open source libraries written in C/C++ was successfully set up,and the Java code was communicated with the C/C++ language.5.On the Android system,Open CV for Android SDK is used to achieve the feature point acquisition,description,matching,tracking and other functions.In the registration process,we use Open GL ES technology to superimpose two-dimensional images of virtual objects onto the video stream in real time,and perform functions such as rendering and mapping at the same time.Finally,an augmented reality system with good effect is obtained,and the expected requirements are achieved in terms of rapidity,stability,and robustness.
