摘　　要：近年来,影视制作技术出现巨大的变革与更新,虚拟摄制技术被广泛应用于电影制作。基于目前影视虚拟摄制中存在无法有效整合镜头与位姿元数据,相关设备稳定性差、易被干扰等问题,本文通过对现有摄影机追踪与跟焦设备进行分析,针对不同场景,提出一种虚拟摄制中镜头和位姿元数据聚合技术方案,搭建相关系统并进行了实验与测试。结果表明,本文提出的镜头和位姿元数据聚合技术能够有效聚合输出稳定且平滑的镜头和位姿元数据,为虚拟摄制现场创制的灵活性与稳定性提供可靠保障。In recent years,film and television production technology has undergone significant transformations and updates,with virtual production technology being widely applied in filmmaking.Addressing current challenges in virtual production,such as the inability to effectively integrate lens and pose metadata,as well as issues like poor stability and susceptibility to interference in related equipment,this paper analyzes existing camera tracking and focus pulling devices.Aiming at diverse scenarios,we propose a technical solution for aggregating lens and pose metadata in virtual production,develop a relevant system,and conduct experiments and tests.Results demonstrate that the proposed aggregation technology effectively outputs stable and smooth lens and pose metadata,providing dependable support for the flexibility and stability of onset virtual production workflows.
