1. A camera system for surgical navigation systems comprising:
a plurality of cameras mounted in a room;
wherein at least three cameras of the plurality of cameras are operated in at least two different modes;
wherein in a first mode of the at least two different modes, at least a first subset of the at least three cameras is operated to determine a position of markers and in a second mode of the at least two different modes, at least a second subset of the at least three cameras is operated to determine a position of surfaces of the room;
wherein a composition of the first subset and the second subset changes over time.
