Claim 0:
1. A magnetic tracking system for determining an object pose of a tracked object in an environment of the magnetic tracking system, the magnetic tracking system comprising:
a plurality of transmitter assemblies, at least one transmitter assembly comprising:
a transmitting coil configured to generate a magnetic signal for the transmitter assembly, the magnetic signal indicative of an object pose of a tracked object with respect to the transmitter assembly; and
a marker that visually identifies a pose of the transmitter assembly with respect to a camera device;

wherein the camera device is configured to capture at least one image of the plurality of transmitter assemblies that includes a representation of the marker on the at least one of the transmitter assemblies; and
a computing device configured to perform operations comprising:
determining, based on the image including the representation of the marker on each of the transmitter assemblies, a pose for the at least one of the transmitter assemblies in the image;
receiving each of the magnetic signals from the at least one of the transmitter assemblies;
determining, based on each of the magnetic signals and the pose associated with the at least one of the transmitter assemblies, the object pose of the tracked object in the environment; and
outputting a representation of the object pose.
