Abstract
Abstract
Surgical navigation systems are used in many fields of surgery to support the surgeon with localization information during operation. Current systems are based on optical or electromagnetic tracking, both with its benefits and drawbacks. The presented approach is an alternative to the established measurement systems to simplify the use of surgical navigation in the operating room. This abstract aims at evaluating if the required accuracy for a surgical navigation application can be achieved by a single camera approach (see Fig. 1). The proposed system uses a single video camera mounted on an instrument and navigates relative to a flat marker mounted on the patient. The required transformation between camera and marker is computed by image processing methods.
