Abstract

Background

In the demanding field of live news broadcasting, the intricate studio production procedures and tight schedules pose significant challenges for physical rehearsals by cameramen. This paper explores the design and implementation of a lightweight virtual news previsualization system, leveraging virtual production technology and interaction design methods to address the lack of fidelity in presentations and manipulations, and the quantitative feedback of rehearsal effects in previous virtual approaches.

Methods

Our system, Previs-Real, is informed by user investigation with professional cameramen and studio technicians, and adheres to principles of high fidelity, accurate replication of actual hardware operations, and real-time feedback on rehearsal results. The system's software and hardware development are implemented based on Unreal Engine and accompanying toolsets, incorporating cutting-edge modeling and camera calibration methods.

Results

We validated Previs-Real through a user study, demonstrating superior performance in previsualization shooting tasks using the virtual system compared to traditional camera setups. The findings, supported by both objective performance metrics and subjective responses, underline Previs-Real's effectiveness and potential in transforming news broadcasting rehearsals.

Conclusions

Previs-Real eliminates the requirement for complex equipment interconnections and team coordination inherent in a physical studio by implementing methodologies complying the above principles, objectively resulting in a lightweight design of applicable version of virtual news previsualization system. It offers a novel solution to the challenges in news studio previsualization by focusing on key operational features rather than full environment replication. This design approach is equally effective in the process of designing lightweight systems in other fields.

Previs-Real：新闻拍摄预演和评估的交互式虚拟预演系统

在要求苛刻的新闻直播领域，复杂的演播室制作程序和紧张的日程安排给摄影师的实际排练带来了巨大的挑战。本文探讨了一种轻量级虚拟新闻预览系统的设计与实现，利用虚拟制作技术和交互设计方法来解决以往虚拟方法在呈现和操作上缺乏保真度以及排练效果的定量反馈的问题。方法Previs-Real系统采用专业摄像师和演播室技术人员对用户进行调查，并遵循高保真度、准确再现实际硬件操作、实时反馈排练结果的原则。该系统的软件和硬件开发是基于虚幻引擎和配套的工具集实现的，结合了尖端的建模和相机校准方法。我们通过用户研究验证了Previs-Real，与传统相机设置相比，使用虚拟系统在预览拍摄任务中表现出卓越的性能。这些发现得到了客观性能指标和主观反应的支持，强调了Previs-Real在改变新闻广播排练方面的有效性和潜力。sprerevision - real通过实施符合上述原则的方法，消除了物理工作室固有的复杂设备互连和团队协作的需求，客观上实现了虚拟新闻预览系统适用版本的轻量级设计。它通过关注关键操作特性而不是完整的环境复制，为新闻演播室可视化中的挑战提供了一种新颖的解决方案。这种设计方法在其他领域的轻量化系统设计过程中同样有效。
