Motion capture (mocap) refers to the process of recording the movements of objects or people, typically for use in animation, video games, film production, and biomechanics research. There are several methods and systems for capturing motion, with the most common being optical, marker-based systems and non-optical, markerless systems. In optical systems, reflective markers are placed on key points of a subject's body, and cameras track their movements, creating a digital representation of the motion. Markerless systems use cameras and advanced algorithms to analyze the movement of a subject without the need for physical markers. Other methods include electromagnetic systems, which use sensors to detect movement, and inertial systems, which rely on accelerometers and gyroscopes to measure motion. Each method has its own advantages, such as accuracy, real-time feedback, and ease of use, making them suitable for various applications across industries.
