Optical Motion Capture Systems

Triangulate the 3D position of a marker between one, two or more cameras that have been pre-calibrated for distance to provide overlapping projections. Tracking a large number of markers or multiple performers is accomplished by the adding more cameras.

These systems can be expensive to buy, require technical expertise to operate and are studio based. They have a relatively small capture area and can suffer from occlusion as well as being complicated to set up.

Magnetic and electrical interference makes these systems highly susceptible to error, they also require extensive data cleaning and technical expertise to operate plus they suffer from limited area of use and lag for realtime use.
