Nowadays, with the growing maturity of action capture technology and the increasing requirements of the game and film industry for action and shooting level, action capture technology has become more and more widely applied. In addition, virtual shooting is widely applied to many TV programs and film production. For example, the movie “The Lion King” released in 2019 was completed using virtual shooting technology. For example, the orangutan king Caesar in the movie “Rise of the Planet of the Apes” was completed by actor Andy Serkis through motion capture and expression capture. In the process of research and use, the synchronization of virtual camera motion attitude has been difficult to solve, and its accuracy needs to be improved. Furthermore, either the traditional single optical motion capture or the inertial motion capture can better tackle the multiplayer motion capture. In order to solve this problem, based on the Unity3D platform, the position of camera and virtual role is accurately located by optical positioning technology, and then inertial attitude sensing technology is used to obtain the attitude of multiple targets, achieving the integration of the optical positioning and the inertial attitude sensor. As a result, the real-time virtual shooting of multiplayer motion capture can be realized.

基于光学定位和惯性姿态传感技术的多人动作捕捉技术实时影视动画虚拟拍摄的应用研究

如今，随着动作捕捉技术的日趋成熟以及游戏和电影行业对动作和射击水平的要求不断提高，动作捕捉技术已得到越来越广泛的应用。此外，虚拟拍摄广泛应用于许多电视节目和电影制作。例如，2019年发行的电影《狮子王》是使用虚拟拍摄技术完成的。例如，电影《猿人的崛起》中的猩猩国王凯撒（Caesar）是由演员安迪·塞尔基斯（Andy Serkis）通过动作捕捉和表情捕捉完成的。在研究和使用过程中，虚拟摄像机运动姿态的同步一直难以解决，其精度有待提高。此外，传统的单光学动作捕捉或惯性动作捕捉都可以更好地解决多人动作捕捉。为了解决这个问题，基于Unity3D平台，通过光学定位技术对摄像机和虚拟角色的位置进行精确定位，然后利用惯性姿态传感技术获取多个目标的姿态，实现了光学系统的集成。定位和惯性姿态传感器。结果，可以实现多人动作捕捉的实时虚拟拍摄。实现了光学定位和惯性姿态传感器的集成。结果，可以实现多人动作捕捉的实时虚拟拍摄。实现了光学定位和惯性姿态传感器的集成。结果，可以实现多人动作捕捉的实时虚拟拍摄。
