Abstract
A camera tracking system is disclosed for computer assisted navigation during surgery. The camera tracking system is configured to identify a reference array tracked by a set of tracking cameras attached to an extended reality (XR) headset, and determine whether the reference array is registered as being paired with characteristics of one of a plurality of surgical tools defined in a surgical tool database. The camera tracking system is further configured to, based on the reference array being determined to not be registered and receiving user input, register the reference array to be paired with characteristics of one of the plurality of surgical tools selected based on the user input. The camera tracking system is further configured to provide a representation of the characteristics to a display device of the XR headset for display to the user.
