3D Markerless Motion Capture Systems

3D markerless motion analysis systems have several advantages over traditional marker-based systems:

Non-invasive: A 3D markerless motion analysis system does not require markers or sensors to be attached to the subject's body, which can be uncomfortable and may interfere with natural movement. This allows for more natural and realistic movement patterns to be analyzed.
More efficient: Markerless systems typically require less setup time and are quicker to calibrate than marker-based systems. This can save time and increase efficiency in data collection.
Greater flexibility: Markerless systems allow for greater flexibility in capturing movement data, as they are not restricted by the placement or number of markers. This allows for a wider range of movements to be analyzed, including complex and multi-joint movements.
With advancements in computer vision and machine learning (AI), 3D markerless motion analysis systems are becoming increasingly accurate in tracking movement. This allows for more precise measurement of joint angles, joint moments, and other biomechanical variables.
