Abstract
A surgical system includes a camera tracking system that determines a first pose transform between a first object coordinate system and the first tracking camera coordinate system based on first object tracking information from the first tracking camera which indicates pose of the first object. The camera tracking system determines a second pose transform between the first object coordinate system and the second tracking camera coordinate system based on first object tracking information from the second tracking camera indicating pose of the first object, and determines a third pose transform between a second object coordinate system and the second tracking camera coordinate system based on second object tracking information from the second tracking camera indicating pose of the second object. The camera tracking system determines a fourth pose transform between the second object coordinate system and the first tracking camera coordinate system.
