Uncertainty of the position

Results and 3D-data measurement uncertainties

Deriving an error budget is not an easy task. The comments of this section may be seen as a first attempt. Yet, the given values are assumed to be calculated conservatively i.e. as a maximum estimation.

• Uncertainty of the position of a generatrix with respect to the cylinder-axis
• Uncertainty of the radial distance of a measurement point from the cylinder-axis
• Comparison with pressure measurements
