Camera System
Theia3D requires a minimum of 6 synchronized video cameras to track movement. However, for accurate tracking in a modest volume a minimum of 8 cameras is recommended. Larger or more complex volumes, more complex movements, or additional people in the volume may require additional cameras. Please see the Camera System Requirements wiki page for more information.
Theia3D is not limited to a specific camera system and in general will work with any system that provides synchronized video files and meets the other Camera System Requirements. There are several camera systems available that can meet these requirements; however, it is important to verify the accuracy of their synchronization. To date, the systems that we have tested and verified to have good performance with Theia3D are:
- Sony RX0 II (www.sony.com) – These are the cameras included in the complete markerless motion capture package that can be purchased directly from Theia. Note that synchronous capture with these cameras requires additional hardware such as control boxes and a network switch (all required hardware is included in the markerless motion capture package).
In addition to the independent camera systems we have tested above, our solution providers offer Theia3D packages with different camera options and the ability to synchronize other hardware such as force plates, an instrumented treadmill, EMG sensors, or traditional marker based cameras with the markerless system. These solution providers include:
Computer
Processing data with Theia3D requires a desktop computer with a CUDA capable graphics card, multi-core processor, and reasonable amount of RAM. The minimum and recommended system specifications are outlined below. Note that any use of Theia3D on a machine that does not meet these minimum requirements, or on a laptop is not supported.
- GPU: One or more CUDA capable graphics cards. NVIDIA RTX 2080, NVIDIA RTX 2080 Super, NVIDIA RTX 2080Ti, NVIDIA RTX 3080, and NVIDIA RTX 3090 are supported.
- RAM: Minimum 24 GB. Recommended 32 GB.
- CPU: Minimum quad-core i7 processor or equivalent. Recommended octa-core i9 processor.
- Updated graphics card driver. The program will not run if the graphics driver is not up to date.
