The Design And Implementation Of Augmented Reality Field Practice System

In recent years,virtual reality technology(VR)augmented reality technology(AR),with its unique interactivity,creativity and authenticity,has made great breakthroughs and wide applications in many fields.Among them,augmented reality technology,with its unique equipment compatibility and portability,has unique technical advantages in the field of education and teaching,and has become the backbone of current educational technology reform and integration.Geography is a subject that emphasizes practical teaching.It requires students to study in school.In addition to mastering the theoretical knowledge of textbooks and the basic steps of experimental operations,they must also be familiar with the practice of the wild natural environment.During the field practice of geography,students can verify the theoretical knowledge learned in the classroom,and deepen their understanding of the basic theories of geological geomorphology,and enhance the ability of field natural geography scientific investigation,which is indispensable for practical teaching of geology.At present,the application of augmented reality technology to the field practice of geography field has been favored by more and more people.It can expand the depth of practice teaching and increase the form of practice teaching.It has great application prospects.It will effectively solve the problems exposed by traditional field practice methods,such as low resource utilization rate and single teaching mode,which improves the efficiency of field practice and brings more available technologies and resources to practice.However,most of the current application development of augmented reality technology and geography teaching practice is at the basic stage.On the one hand,augmented reality technology is developing rapidly,and the application system development has not been able to be discussed and designed in a timely and in-depth manner.On the other hand,system development involves specialized content such as geospatial information databases and system symbol design,and technological innovations have not effectively matched and adapted to it.As a result,the current research on the combination of augmented reality technology and geographic field practice teaching is slow,and the teaching needs of teachers and students are not met.In response to the above problems,this paper designs and implements a prototype system of geographic field practice based on augmented reality technology.The system development revolves around the field practice of the geography subject,with the emerging augmented reality technology as the technical means,the practice system as the application service,dynamic and interactive operation as the main features,and the personal-oriented assisted learning as its main purpose,focusing on solving augmented reality The technical application development,system database design,system visual design and other contents have completed the design and implementation of the augmented reality geographic field practice system.This article mainly carried out the following work:(1)Summarized and analyzed the research status of augmented reality technology and geographic field practice,pointed out some problems and deficiencies in the research of the combination of augmented reality and geographic field practice,clarified the main research ideas and research content of the thesis,and determined the thesis research Overall framework.(2)Explained the application of augmented reality technology and the contents of geographic field internship,discussed the method of virtual and real integration of geographic field internship system,proposed the technical points of augmented reality geographic field internship system,and completed the prototype of augmented reality geographic field internship system requirements.(3)Deeply explored the application design and integration of augmented reality technology involved in the system.This article explores in detail the technical means and methods of augmented reality technology fusion and development,multi-source heterogeneous data information collection technology,data integration and fusion.Not only the design and construction of the prototype of the augmented reality geographic field practice system based on Unity3 D,Android Studio and other development platforms,but also the realization of mobile terminal device attitude calculation and augmented reality tracking registration method,but also integrates multisource heterogeneous geographic information data Designed the organization and management methods of multi-source media materials,completed the in-depth exploration of complex technology development and application methods.(4)Inquire into the visualization of geoscience data oriented to system content design.This paper explores the rules of system visual symbol expression and designs the symbolic visual expression of augmented reality geographic field practice system.And by combing the system module functions and using the teaching application mode as a reference,the specific functions of the field practice system are designed and realized,and the system is delivered to relevant teachers and students,and preliminary feedback evaluation is obtained.This system realizes the complete application of augmented reality technology on the mobile terminal,provides a feasible solution for the integrated development of augmented reality technology and geography teaching,verifies the effectiveness of the system-assisted teaching method,and provides a theoretical reference for the reform and integration of teaching technology in other disciplines,Which plays a reference role in the integration design research of augmented reality and various discipline systems..
