摘要：
A system and method of training how to se a medical device using an instrument such as a mock ultrasound probe or syringe to be tracked in 3D space with six degrees of freedom using an internal optical camera, a light source (e.g. infrared LEDs), and a display of markers arranged on a surface. By extracting corner information for each marker, a 3D transformation can be established, allowing the system to know the instrument's position and orientation in 3D space relative to that marker. Each marker also encodes a numerical value corresponding to its predetermined position and orientation on the surface, allowing the instrument to determine its own position and orientation relative to the surface. Thus, as long as the instrument is able to see at least one marker on an optical surface, the system will know its full 3D position and orientation relative to the whole optical surface.
