Eve Gmotion high-speed motion capture system is a set of integrated multiple motion capture cameras, motion capture software and related accessories for large space positioning program, solution. The system captures the human body, helmet displays, interactive devices, and fixed special markers (passive marker points) on the rigid body at hundreds of frames per second, and accurately constructs the human body's skeletal information or marker point 3D position information in real time, providing a set of advanced tools to accurately obtain human body movement data and rigid body position data in real time for users in the fields of virtual reality, drones and robots, biomechanics, film and animation, and other applications. The system has a flexible building environment, and it can be used in a variety of applications such as virtual reality, UAV and robotics, biomechanics, film and animation. The system features flexible building environment, sub-millimeter (0.1mm) positioning accuracy, real-time six-degree-of-freedom data transmission to the client, and personalized path simulation design.
