Research On The Recognition,Tracking And Registration Algorithm Of High-tech Words AR Display In "The Belt And Road" Construction

"The Belt and Road" is the abbreviation of "Silk Road Economic Belt" and "21st Century Maritime Silk Road".Policy coordination,facility connectivity,unimpeded trade,financial integration,and people-to-people bonds are the main content of strengthening cooperation among countries along the route.Language interoperability is an important aspect of "The Belt and Road" interconnection.Strengthening the study of language ability and improving language ability is a very important and urgent research task in the construction of the "The Belt and Road".However,in the current promotion of high-tech words,such as:Alipay,clean energy photovoltaic power generation,BeiDou Navigation Satellite System and other characteristic words,it is difficult for teachers to explain each knowledge point clearly in language.Moreover,the comprehension of each learner is not the same,and the teaching effect will vary from person to person.Augmented reality technology is an extension of virtual reality technology.It integrates real world information and virtual world information,and realizes the interaction between the virtual world and the real world on the screen.The use of AR technology to promote high-tech words can directly present unimaginable things with a three-dimensional model.This method can help learners understand and remember,enrich learners' imagination,and help the people of the countries along "The Belt and Road" learn high-tech vocabulary quickly and effectively,and master the context of use.Therefore,this paper studies and designs the AR system framework,which improves the robustness of the AR system while realizing the immediacy of the AR system.Then,this paper uses the twelve high-tech words and related vocabulary related to the economic construction of the "The Belt and Road" to realize the high-tech words AR atlas system.The main research work is as follows:(1)This paper proposes an improved feature point detection and matching algorithm(BOHP),which solves the problem of scale invariance.This algorithm not only improves the computational efficiency,but also improves the accuracy of matching.Regardless of the viewing angle,brightness,illumination,rotation,and scale changes,the method in this paper has good real-time and robustness,which lays the foundation for the realization of the high-tech word AR atlas system.(2)This paper improves the existing AR tracking and registration method based on optical flow,and combines the tracking failure detection algorithm to propose an AR tracking and registration method based on characteristic optical flow(C-LSF).When the feature points are lost or the tracking accuracy is reduced,the method in this paper can still complete the accurate virtual and real registration,and meet the needs of real-time stability of the AR system.(3)According to the practical significance of the promotion of high-tech words in Chinese as a foreign language,this paper designs and implements a high-tech vocabulary atlas system based on AR technology.The system uses AR display to introduce my country's high-end technology products represented by China's high-speed rail,aviation,photovoltaic power generation and satellite navigation to foreign learners.This method enhances learners' sense of presence and immersion in learning,and promotes the application of my country's high-tech in countries along"The Belt and Road".
