Claim 7:
8. A method of determining a vector relationship between a first sensor system and a second sensor system of a welding helmet, the method comprising:
determining, via processing circuitry, an initial first position and an initial first orientation of a first sensor system relative to a reference point based on initial first sensor data captured by the first sensor system;
determining, via the processing circuitry, an initial second position and an initial second orientation of a second sensor system relative to a stationary trackable object based on initial second sensor data captured by the second sensor system, the first sensor system being in a fixed spatial relationship relative to the second sensor system, the first and second sensor systems comprising a helmet sensor system;
after a first duration of movement of the helmet sensor system, determining, via the processing circuitry, a subsequent first position and a subsequent first orientation of the first sensor system relative to the reference point based on subsequent first sensor data captured by the first sensor system,
after the first duration of movement of the helmet sensor system, determining, via the processing circuitry, a subsequent second position and a subsequent second orientation of the second sensor system relative to the trackable object based on subsequent second sensor data captured by the second sensor system; and
determining, via the processing circuitry, the vector relationship between the first sensor system and the second sensor system based on the initial first position of the first sensor system, the initial first orientation of the first sensor system, the initial second position of the second sensor system, the initial second orientation of the second sensor system, the subsequent first position of the first sensor system, the subsequent first orientation of the first sensor system, the subsequent second position of the second sensor system, and the subsequent second orientation of the second sensor system.
