Design And Implementation Of Interactive Ar System For Campus Roaming, Shengwei Qin, Li Zhong, Jinfeng Li, Zihao Chen, Jingqian Ding, Wanshun Liu
Journal of System Simulation
Abstract: There are many kinds of navigation applications in universities recently. These applications have obvious shortcomings, which only indicate the outdoor locations without detail information; even some places cannot be found in the map; and it takes a lot of time to design a system. Meanwhile the system cannot achieve real-time interaction effect in virtual ramble. An interactive campus roaming augmented reality (AR) system is designed combining with GPS module for locating outside the campus and utilizing deep learning technology to achieve locating the inside buildings of campus. Simultaneously AR technology will improve interactivity of the system. The experiment …

Collaborative Mixed Reality (MR) systems are at a critical point in time as they are soon to become more commonplace. However, MR technology has only recently matured to the point where researchers can focus deeply on the nuances of supporting collaboration, rather than needing to focus on creating the enabling technology. In parallel, but largely independently, the field of Computer Supported Cooperative Work (CSCW) has focused on the fundamental concerns that underlie human communication and collaboration over the past 30-plus years. Since MR research is now on the brink of moving into the real world, we reflect on three decades …
A Framework For Test & Evaluation Of Autonomous Systems Along The Virtuality-Reality Spectrum, Nathan D. Gonda
A Framework For Test & Evaluation Of Autonomous Systems Along The Virtuality-Reality Spectrum, Nathan D. Gonda
Computational Modeling & Simulation Engineering Theses & Dissertations
Test & Evaluation of autonomous vehicles presents a challenge as the vehicles may have emergent behavior and it is frequently difficult to ascertain the reason for software decisions. Current Test & Evaluation approaches for autonomous systems place the vehicles in various operating scenarios to observe their behavior. However, this introduces dependencies between design and development lifecycle of the autonomous software and physical vehicle hardware. Simulation-based testing can alleviate the necessity to have physical hardware; however, it can be costly when transitioning the autonomous software to and from a simulation testing environment. The objective of this thesis is to develop a …
Collecting Virtual And Augmented Reality In The Twenty-First Century Library, Matthew Hannah, Sarah Huber, Sorin Adam Matei
Collecting Virtual And Augmented Reality In The Twenty-First Century Library, Matthew Hannah, Sarah Huber, Sorin Adam Matei
Matei Interdisciplinary Research Collaboratory
In this paper, we discuss possible pedagogical applications for virtual and augmented reality (VR and AR), within a humanities/social sciences curriculum, articulating a critical need for academic libraries to collect and curate 3D objects. We contend that building infrastructure is critical to keep pace with innovative pedagogies and scholarship. We offer theoretical avenues for libraries to build a repository 3D object files to be used in VR and AR tools and sketch some anticipated challenges. To build an infrastructure to support VR/AR collections, we have collaborated with College of Liberal Arts to pilot a program in which Libraries and CLA …
Target Tracking Simulation For Unmarked Augmented Reality System Based On Kcf, Zhili Zhang, Wang Chao, Long Yong, Shaodi Wang
Target Tracking Simulation For Unmarked Augmented Reality System Based On Kcf, Zhili Zhang, Wang Chao, Long Yong, Shaodi Wang
Journal of System Simulation
Abstract: An AR system based on the kernelized correlation filter (KCF) target tracking is designed for solving the problem of the insufficiency of tracking in the unmarked augmented reality (AR). The KCF is used to identify and track the targets. The relevant parameters of the camera position are imported. The openGL graphical program interface is called to load the precast object onto the target. The KCF simulation experiment is carried out to track the target with visual studio. The results show that the AR application system based on KCF method can effectively improve the real-time performance of target tracking, and …

Simulation System For Special Material Processing Training Based On Augmented Reality Technology, Bin Luo, Shuangquan Ge
Journal of System Simulation
Abstract: A simulation system for special material processing training within the shielded environment is developed based on augmented reality technology. An observation system composed of analogue camera and network high dome system camera is designed and constructed to extend the view scope of operators. Single hand finger recognition technology is then combined with the observation system to implement friendly interactions between operators and the simulation system, and to achieve interactive training. Augmented reality technology is applied to create fused virtual-real vision, which leads to the implementation of augmented processing induction of cone-shaped part. Primary tests show that the developed …

© 2019, This is a U.S. government work and not under copyright protection in the U.S.; foreign copyright protection may apply. When collecting real-world imagery, objects in the scene may be occluded by other objects from the perspective of the camera. However, in some circumstances an occluding object is absent from the scene either for practical reasons or the situation renders it infeasible. Utilizing augmented reality techniques, those images can be altered to examine the affect of the object’s occlusion. This project details a novel method for augmenting real images with virtual objects in a virtual environment. Specifically, images from …
