"VatoSABA 1.2." Motion Capture System for Computerised Movement Analysis

Biomechanical analysis of human movements is a complex and demanding job, thus virtual 3D characters of computer-generated kinematic and locomotive man-like systems are used in practice. Human skeleton can be seen as a set of a closed kinematic chain (spine with chest) and five kinematic chains (head, arms and legs). A computerised kinematic model is developed based on the inner body kinematic model, to be used as an initial basis for the construction and character animation of a virtual 3D character. To accomplish a scientific visualisation of 3D characters the following is necessary: to design and develop an animated skeleton model with accompanying data basis for movements, to design and model 3D model body and through computer animation achieve interaction of the virtual model and its environment. A traditional approach of 3D-character animation includes the usage of key frame animation. This approach is rather cheap, but time consuming, and offers rather good animation results. A mode modern, popular, fast and accurate, but much more expensive, approach is based on a "Motion capture (mocap)" system. Theses systems can automatically detect movements of real people. VatoSABA 1.2. Motion Capture system digitises real movement recordings into adequate behaviour of 3D characters, and constitutes a new approach to computerised character animation of 3D virtual humans, including both modest investments and ease of operation in animating key frames, together with a precise and quick work, as when using automatic motion capture digital systems.
