1. A camera tracking bar of a camera tracking system for computer assisted navigation during surgery, the camera tracking bar comprising:
a first set of stereo tracking cameras having a first resolution, a first field of view, and spaced apart on the camera tracking bar by a first baseline distance;
a second set of stereo tracking cameras having a second resolution, a second field of view, and spaced apart on the camera tracking bar by a second baseline distance;
a communication interface configured to provide video streams from the first set of stereo tracking cameras and the second set of stereo tracking cameras to the camera tracking system;
a processor configured to align orientation of the video streams and motion data measurements to a gravity reference; and
a microphone array including a plurality of microphones spaced apart along the camera tracking bar and connected to provide at least one audio stream to a computer platform,
wherein the first resolution and the first field of view of the first set of stereo tracking cameras are configured to output frames in the video stream imaging a reference array posed during surgery extends across a pixel array of at least 10 pixels by 10 pixels and not more than 30 pixels by 30 pixels.
