Motion Capture is an equipment used to capture all or part of a person's physical movements, shifts, and in some cases facial expressions. The movements are then translated into the behavior of a 3D digital character.
Motion Capture
ImagePer MelanderThe motion tracking system operated by Humlab currently consists of up to 24 cameras, half of which are Prime 22 models, and the other half are Prime 13 models from Optitrack. In our facilities, we have 22 cameras installed, providing a recording volume of 6x6x3 meters, limited by the size of the room. Optitrack’s hardware and software are among the world’s leading providers in motion tracking, with an accuracy of approximately ±0.15mm per x, y, z coordinate. The system uses passive reflectors as markers, which reflect infrared light from the cameras. Additionally, it is possible to use active markers with this system.
We are capable of capturing multiple human bodies with over 50 markers per person, along with fixed objects. The number of markers can vary depending on the desired outcome. Recordings can be made at up to 360 frames per second.
The system is intended for use by researchers, educators, and students/creators who want to study or utilize body movements, virtual production, animation, VR, or robotics.
The software, Motive, can either record sessions or stream live to other applications. These recordings can then be exported in various formats to meet specific needs. Supported 3D engines include Unity3D and Unreal, and several other export formats allow for analysis and processing of 3D data using tools such as Python, R, Matlab, Blender, Motionbuilder, Visual 3D, and other programs.
