Development Of Experimental Equipment Safety Operation Training System Based On AR

Augmented Reality(AR)is a new technology that expands and adds additional virtual information to the real world by means of computer technology.With its application and popularization,AR technology has gradually developed in various fields,but it still needs to be explored in the field of mobile education.With Unity3 D and Vuforia as development engines and tools,this paper designs and develops a teaching augmented reality software of circuit experiment training system based on Android platform,and realizes the demonstration experiment of measuring internal resistance of conductor with millivoltmeter.Firstly,this paper summarizes the background,significance and development status of augmented reality in education.Then,the research of target image feature extraction and camera calibration technology in training system,the demand analysis and overall design of AR experimental equipment,the demand analysis and overall design of AR experimental equipment,and the design of safe operation module of AR-based circuit experimental system are presented.The research contents are described.The demand analysis and overall design of AR experimental equipment are also introduced.The design process of AR circuit experimental system in Unity and the development and effect display design of AR circuit experimental system mobile phone APP are also introduced.Ultimately,users can see a complete circuit experiment process on Android mobile phone.Finally,the safe operation module is designed,and the specific design is introduced in detail from the aspects of education security and accident monitoring security.The training system is aimed at complex circuit experiment operation,and the equipment is expensive and fragile.It is difficult to observe the shortcomings of the experimental results.A circuit experiment platform based on mobile augmented reality technology is built,and the demonstration experiment of measuring the internal resistance of conductor with millivoltmeter is designed and implemented.According to the process and thinking of the experiment,the main modules of the design include selection interface module,database module,model drawing module,identification module and enhanced reality display module.The platform is used in the field of mobile education and is an easy-to-operate,interesting and advanced assistant tool for physics experiment teaching.
