0708_ Unity WebRTC + Paper
1. WebRTC :
WebRTC (Web Real-Time Communication) is a technology which enables applications to capture and optionally stream audio and/or video media, as well as to exchange arbitrary data between apps without requiring an intermediary. The set of standards that comprise WebRTC makes it possible to share data and perform teleconferencing peer-to-peer, without requiring that the user install plug-ins or any other third-party software.
2. Content Persistence : Local
3. Transmission
Transmission is a cross-platform solution for connecting devices over a local area network (LAN).
Add Transmission to your Unity app to provide a basic, multi-user network connection between Magic Leap 1 devices, computers, mobile devices, and any other device connected to the same LAN. Low-level networking is handled directly through UDP.
Transmission is a valuable tool for the development of collocated, multi-user experiences. Transmission can be used to share messages, call remote commands, and synchronize the placement of objects.
To align objects between peers you will need to use the Spatial Alignment component to your system.
Transmission 은 LAN을 통해 두 디바이스를 연결하는 중계플랫폼이다.
Transmission을 사용하면 같은 LAN으로 연결된 multi user들이 하나의 어플리케이션을 함께 즐길 수 있다.

3-d multistatic ground penetrating radar imaging for augmented reality visualization
Mauricio Pereira, Dylan Burns, Daniel Orfeo, Yu Zhang, Liangbao Jiao, Dryver Huston, Tian Xia
IEEE Transactions on Geoscience and Remote Sensing 58 (8), 5666-5675, 2020
Ground penetrating radar (GPR) is a useful instrument for smarter infrastructure applications, in particular, for the localization and mapping of underground infrastructure and other subsurface assets, due to its ability to sense metallic and nonmetallic buried objects. For instance, air-coupled, multistatic GPR could potentially be employed to quickly produce subsurface maps for public and private stakeholders, enabling rational and more efficient planning of underground infrastructure inspection, maintenance, and construction. An application of interest in such context is a faster identification of underground utilities location and depth by innovative data visualization methods, such as augmented reality. A 3-D model of the subsurface asset is desirable for such applications. However, raw GPR data is often hard to interpret. Imaging algorithms are applied to improve GPR data readability and signal-to-noise ratio by focusing the spread energy. Here, a processing pipeline that takes raw 3-D multistatic GPR data as input and yields a 3-D model as output is proposed. Initially, a 3-D back-projection algorithm is applied to air-coupled, multistatic GPR data to recover buried target localization. An enhancement filter, tailored for tubular structures, is applied to reduce background noise and highlight structures of interest in the 3-D image. This process is successfully applied to three laboratory scenarios of plastic buried targets with different sizes and shapes.

Mobile augmented reality technology for design and implementation of library document push system
Jing Lu
Journal of Real-Time Image Processing 18 (2), 283-293, 2021
Through mobile augmented reality interaction, the
Bg: library can keep abreast of the user’s current information orientation and lay the foundation for the further establishment of a personal information database.
At the same time, on the basis of network interaction, it plays a good guiding role for the construction of library document resources, ensuring the effective use of document resources. This paper analyzes the key technologies of the mobile augmented reality system, including virtual graphics rendering technology, camera tracking and positioning technology, display technology and so on.
To solve the problem of human error caused by design deviation in the current mobile augmented reality library document push, a new data visualization and interactive design process is proposed.
On the basis of analyzing user needs and comparing augmented reality library document push with traditional library document push, the demand is transformed into tasks.
Solution : We use a combination of overview and detail to lay out the visual elements. The progressive interactive method is used to organize discrete data views and generate interactive interfaces.
The system test results show that the library document pushing system designed in this paper can effectively reduce the memory consumption of the system, improve the refresh frame rate of the view and improve the user’s interactive fluency.
