Abstract
A tracking array tracking system, including: at least one processor; and at least one memory storing instructions, that when executed by the at least one processor, cause the tracking array system at least to: determine that one marker of a plurality of markers on a tracking array is obstructed to a camera system; identify marker lines on the tracking array; determine a location of the marker lines of the tracking array; and determine a location and orientation of the tracking array based upon the location of the marker lines.
Claims21
A tracking array tracking system, comprising:
- at least one processor;
- and
- at least one memory storing instructions, that when executed by the at least one processor, cause the tracking array tracking system at least to:
- determine that one marker of a plurality of markers on a tracking array is obstructed to a camera system;
- identify a plurality of marker lines on the tracking array;
- determine a location and orientation of the marker lines of the tracking array;
- and
- determine a location and orientation of the tracking array based upon the location and orientation of the marker lines;
- wherein the step of identifying includes identifying, if the camera system has seen at least two marker line segments, a marker line of said plurality of marker lines comprising said at least two marker line segments when the at least two marker line segments are colinear.
A method for tracking a tracking array in a computer aided surgery system, comprising:
- determining that one reflective element of a plurality of markers on the tracking array is obstructed to a camera system;
- identifying a plurality of marker lines on the tracking array;
- determining a location and orientation of the marker lines of the tracking array;
- and
- determining a location and orientation of the tracking array based upon the location of the marker lines;
- wherein the step of identifying includes identifying, if the camera system has seen at least two marker line segments, a marker line of said plurality of marker lines comprising said at least two marker line segments when the at least two marker line segments are colinear.
A method for tracking a tracking array in a computer aided surgery system, comprising:
- identifying a plurality of marker lines on the tracking array;
- determining a location and orientation of the marker lines of the tracking array;
- and
- determining a location and orientation of the tracking array based upon the location and orientation of the marker lines;
- wherein the step of identifying includes identifying, if the camera system has seen at least two marker line segments, a marker line of said plurality of marker lines comprising said at least two marker line segments when the at least two marker line segments are colinear.
