Startup Window
The startup window appears if Select GPUs on launch is enabled in the Theia3D setup preferences.
GPU Selection
Select which graphics card(s) to use when running Theia3D.
Depending on the available graphics cards, Person threads and Joint threads may also be adjustable.
When running Theia3D on a laptop, use Laptop mode for optimal performance.
Person Tracking
Select which person detector size to use when running Theia3D, and set the Skip frames count.
Small: fastest, may be slightly less accurate than Medium or Large.
Medium: recommended.
Large: slowest, may be slightly more accurate than Small or Medium.
Skip frames (default: 1, maximum: 5) sets the frame interval used during the analysis process to identify and track people. Increasing this value will speed up the person detection part of the analysis. This works best for movements where the person does not move much between frames, and should not be used for fast movements recorded at relatively low frame rates, or movements with multiple closely-interacting individuals, as the person identification may be affected.
Joint Tracking
Select which joint detector size to use when running Theia3D:
Small: faster, may be slightly less accurate than Large (currently disabled).
Large: (default) slower, may be slightly more accurate than Small.
Hand Tracking options are available as a license add-on by special request only, and require camera views that are positioned specifically to capture the hands and upper body. Please reach out to Theia Support for more information.
Refine Hands: improves hand tracking when the hands are clearly visible and large enough in the image,
Track Fingers: tracks individual finger segments. Both features are currently in beta.
Object Tracking
Object Tracking options are available as a license add-on only. Please reach out to Theia Support for more information.
Linked Object Tracking: enables tracking for objects attached to or used by a person, such as a baseball bat.
Free Object Tracking: enables tracking for independently moving objects, such as a baseball.
Listen Mode
Listen Mode is available as a license add-on by special request only. Please reach out to Theia Support for more information.
Listen Mode allows a directory to be selected where data is saved during data collection. The selected directory will be actively monitored for new, unprocessed data which will be automatically analyzed as it is detected. This allows data to be processed during an active data collection session, enabling shorter turnaround times for collected data.
