Abstract
A camera tracking bar of a camera tracking system for computer assisted surgery navigation. The camera tracking bar includes a first set of stereo tracking cameras having first resolution, first field of view, and spaced apart on the camera tracking bar by a first baseline distance. The camera tracking bar also includes a second set of stereo tracking cameras having second resolution, second field of view, and spaced apart on the camera tracking bar by a second baseline distance that is less than the first baseline distance. The second set of stereo tracking cameras is positioned between the first set of stereo tracking cameras, and the resolution and/or the field of view of the second set of stereo tracking cameras is different from the resolution and/or the field of view of the first set of stereo tracking cameras. A communication interface provides camera video streams to the camera tracking subsystem.
