Collaborative Virtual Observation in Dynamic Environments

该项目的目标是开发一个框架，用于随时随地协作虚拟观察动态环境中发生的事件。该方法是通过采用为普适计算系统开发的软件服务组合机制来增强最近开发的虚拟观测概念。在不同的时间和空间点上进行的观察，根据位置、查询、设备和其他变量拼接在一起。在由连续和容忍中断的通信通道组成的异构网络中，用于数据包软实时传输的协议正在开发中。正在创建中间件工具来执行响应式和主动式查询处理、匹配和综合全景视图。所提出的工作的智力价值在于，在软实时的情况下，在移动环境中的任何设备上启动虚拟观察者，并将连续的虚拟观察者串联起来创建虚拟旅行。为动态和异构环境中的视频采集、流处理、视频合成、机会网络和集成普及服务开发集成框架是本项目的贡献。就更广泛的影响而言，该研究有可能为公共场所视频监控和安全领域提供新的见解。总体而言，本项目的成果在科学制造、教育、国土国防、娱乐等领域具有广泛的适用性。与科廷大学的国际合作使研究生，包括那些来自代表性不足群体的研究生，能够与澳大利亚的学生和研究人员互动，从而扩大他们的知识和技能。

The objective of this project is to develop a framework for anytime, anywhere collaborative virtual observation of events occurring in dynamic environments. The approach is to enhance recently developed virtual observation concepts by adapting software service composition mechanisms developed for pervasive computing systems. The observations, made at different points in time and space, are stitched together based on location, query, device, and other variables. Protocols for soft-real time delivery of data packets in heterogeneous networks comprising a combination of continuous and disruption tolerant communication channels are being developed. Middleware tools are being created to perform reactive and proactive query processing, matching, and synthesis of integrative panoramic views.The intellectual merit of the proposed work lies in the launching of the virtual observers, in retrospect, in soft real-time, on any device in a mobile environment and the concatenation of successive virtual observers to create virtual tours. Development of an integrated framework for video acquisition, stream processing, video synthesis, opportunistic networking, and integrated pervasive services in dynamic and heterogeneous environments are contributions of this project.With respect to broader impact, the research has the potential to provide new insights in the areas of video surveillance and security of public places. In general, outcomes of this project have broad applicability in such areas as science manufacturing, education, homeland defense, and entertainment. International collaboration with the Curtin University enables graduate students, including those from underrepresented groups, to interact with students and researchers in Australia, thus broadening their knowledge and skills.
