3Drörelserekonstruktion

3Drörelserekonstruktion refers to the process of recreating and analyzing the three-dimensional movement of objects or individuals, often from collected data. This technique is widely applied in various fields, including biomechanics, sports science, computer animation, robotics, and forensic analysis. The core principle involves capturing a series of points or markers in space over time to build a digital representation of motion.

The data acquisition for 3Drörelserekonstruktion can be achieved through several methods. Motion capture systems, utilizing optical markers and infrared cameras, are a common approach, tracking the precise positions of reflective markers placed on the subject. Inertial measurement units (IMUs) that detect acceleration and angular velocity can also be used, sometimes in combination with optical systems. Markerless motion capture, which analyzes video footage without physical markers, is an emerging technology.

Once the raw data is collected, specialized software is employed to process it. This involves calibrating the system, identifying and tracking markers or key body points across frames, and then reconstructing their trajectories in a three-dimensional coordinate system. The resulting data can then be used for detailed analysis of movement patterns, forces, and biomechanical efficiency. Applications range from improving athletic performance and designing prosthetics to creating realistic character animations in films and video games, and even reconstructing accident scenes.
