Research On Core Technology Of Multiplayer Interactive Augmented Reality Game In Mobile Terminal

In recent years,with the improvement of the performance of hardware and the development of computer graphics technology,the Augmented Reality(AR)technology has gradually become a research hotspot of scholars.AR technology enables people to experience more than reality by seamlessly integrating virtual world with the real world.In 2016,the popularity of Pokemon Go made people realize the great potential of AR technology in mobile games.The AR game can associate players,the real environment with the virtual objects in the game,which is different from the traditional game where players can only control the virtual objects in the display screen by command.it can bring fresh experience to the players and increase the intimacy of the users.But there are a few successful mobile games in the market today,and most of AR games are just experimental games.In order to enrich the AR game,increase the gameplay and interactivity of AR game,broaden the way for developing mobile AR game,this topic researches core technology of multiplayer interactive augmented reality mobile game.Firstly,this paper studies three core technologies of augmented reality and put emphasis on the implementation principle of related technologies on mobile devices.Secondly,this paper researches the architecture of mobile multiplayer interactive game,and puts forward the strategy of bandwidth control of the game in order to reduce the network bandwidth pressure of the client and server.Research on global time synchronization problem,data synchronization algorithm and corresponding break line reconnection mechanism of network game,and analysis of advantages and disadvantages of different synchronization algorithm is conducted.The paper summarizes the selection strategy of synchronization algorithm as well.Then,this paper put forward an optimized frame synchronization algorithm according to the characteristics of the mobile terminal's multiplayer interactive AR game.With this algorithm,the load pressure of the game server can be reduced while running process.Moreover,the client consumes less traffic and the game runs smoothly,and thus quickening the re-connection of the net suspension.Finally,combining the above research results,applying the Unity engine and pomelo game server,the optimized frame synchronization algorithm and reconnection plan,and application of augmented reality,this paper designs and implements a multiplayer interactive augmented reality game "crazy zoo" on the ground of LBS technology.The game can run on many mobile devices,and players can play in one game room,and have a good augmented reality display effect,which increases the interest of the game.Moreover,it can be reconnected quickly after the network break,which indicates the game design is good,and prove the algorithm is correct.
