(a) Principle of armless navigation system with emitting infrared diodes on the pointer and a three-camera system as receiver. (b) Armless navigation system with a two-infrared camera system and emitting diodes on the pointer during intraoperative registration. The localization of the pointer is calculated by triangulation method.
