Abstract
The invention provides a system and method for testing and correcting the accuracy of a tracking device in a volume using an accuracy device. The invention may include placing a rigid object into an experimental volume and sampling position and orientation information regarding one or more position indicating elements at known positions relative to a frame of reference of the tracking device. The position and orientation information may then be compared to known baseline position and orientation information. If a difference between the experimental position and orientation information and the baseline position and orientation information exceeds a predetermined threshold, a correction map enabling adjustment of the tracking device to correct for the distortion in the experimental volume may be generated, and the tracking device may be adjusted accordingly.
