LOMWIN
DSP status: The status of the most recent calculation. A zero or positive value indicates the number of
iterations required to compute the camera's position and orientation. A negative value indicates a failure:
• 255 = too few targets
• 254 = failed to converge
• 253 = DSP reset
• 252 = internal error.
RMS error: The residual error, in pixels. This is a measure of how close the target images are to their
theoretical positions. A value in excess of 0.1 should lead to a suspicion that a studio calibration is
required, or that the wrong camera calibration file is being used.

The System Status panel displays information on the overall status of the free-d system. The status
indicators are defined as:
Video input: The status of the video input from the free-d camera:
• OK
OK
0
2.5
2.7
2.1
• FAIL (the video input is absent)
• FAULT (the video input is present but unlocked or otherwise faulty)
• FREEZE (the video image is 'frozen' e.g. during data acquisition.
Fault code: Either zero, signifying no fault, or a value signifying a fault condition. See the Free-d
communication protocols for more information.
CPU version: The version number of the firmware running in the single-chip CPU controlling the free-d
processor unit.
DSP version: The version number of the software running on the Digital Signal Processor which performs
the camera position and orientation calculation.
PLD version: The version number of the programmable logic configuration.
