项目摘要

Abstract0313056Swindlehurst, ArnoldBrigham Young UniversityCurrent audiovisual recording, communication, and playback provides a single, two-dimensional perspectiveof the world as it varies through time. Humans live in a \four-dimensional" world, in which they move about(in 3-D space over time) at their own volition to experience the world from any perspective. Advances insensor, computer, and networking technologies now make possible new systems that employ multiple cam-eras and microphones together with sophisticated processing algorithms to deliver unprecedented immersiverecording and viewing capabilities. Sufficient sensing, networking, and computing power to practically ad-dress this vision already exists; the critical gap in achieving it is the lack of the necessary signal processingtheory and algorithms.This research will develop new signal processing techniques for reconstruction of the audio and visualrecording at an arbitrary location in space and time from multiple acoustic and video sensors, by extendingrecent research in adaptive beamforming, multisensor signal processing of non-stationary signals, and fun-damental new advances in multi-dimensional signal representation. Practical four-dimensional audiovisualrecording, transmission, and playback, or \remote reality", will be demonstrated with low-cost, conven-tional sensors attached to networked computers, thus confirming the practicality of the proposed methodsand applications.

摘要0313056Swindlehurst，阿诺德·杨百翰大学当前的视听记录、通信和回放提供了随时间变化的世界的单一二维视角。人类生活在一个“四维”世界中，他们可以按照自己的意愿移动（随着时间的推移在 3D 空间中），从任何角度体验世界。传感器、计算机和网络技术的进步现在使新系统成为可能采用多个摄像头和麦克风以及复杂的处理算法来提供前所未有的沉浸式记录和观看功能，以实际实现这一愿景已经存在的关键差距是缺乏；必要的信号处理理论和算法。本研究将通过扩展自适应波束形成、非平稳信号的多传感器信号处理等方面的最新研究，开发新的信号处理技术，用于从多个声学和视频传感器在空间和时间的任意位置重建音频和视频记录。实用的四维视听记录、传输和回放或“远程现实”方面的基本新进展将通过连接到网络计算机的低成本传统传感器来展示。确认所提出的方法和应用的实用性。
