3d visualizing tool for motion analysis - (abstract)
For this thesis a 3D visualizing tool to reconstruct human movements for motion analysis has been developed. The required moving data is extracted from video material by an optical motion capture software. The tool simulates this motion data on a three dimensional skeleton. The biomechanical parameters that exactly describe human movements are discussed, which leads to the forces caused during motion and affect the human body. These forces can be measured by a force plate during the motion capture process and are also visualized in the simulation through vectors.
With the help of the 3D visualizing tool it can be shown that a realtime 3D animation of any movement enhances the validity of motion analysis. Reasons are a more natural representation of human motion by a virtual skeleton and also the possibility to show the coherence between the forces and the movement itself. Within a 3D scene several movements can be compared and thus differences can be easily located.
