OptiTrack: Optical Tracking Tools
This system records movements on 6 degrees of freedom of an object (displacements and rotations in X, Y and Z) by tracking a number of markers attached to the object. The technology is based on several high-speed cameras calibrated and synchronized with each other, defining a volume in which it is capture movement of that markers and. later, movement records are moved to a digital model by Tracking Tools software. The software delivers 3D matrices (x,/,z) data, which are analyzed by MATLAB.
