运动捕捉（MoCap）是一种使用 外部 定位设备，用于估计载具三维姿态（位置与方向）的 计算机视觉 (opens new window)技术。 It is commonly used to navigate a vehicle in situations where GPS is absent (e.g. indoors), and provides position relative to a local co-ordinate system.
MoCap systems most commonly detect motion using infrared cameras, but other types of cameras, Lidar, or Ultra Wideband (UWB) may also be used.
Note MoCap is conceptually similar to Visual Intertial Odometry (VIO). The main difference is that in VIO the vision system runs on the vehicle, and additionally makes use of the vehicle IMU to provide velocity information.
