ImageIron provides camera specific parameters

Distortion

ImageIron does not determine the distortion in form of equation coefficients, as it is the case with some competitor products, but accomplishes a specific spline calculation. Thus a higher accuracy is reached, since the distortion behavior is not reduced to the coefficients of a quadratic equation.

The distortion data can be examined in several ways:

• Representation of the distortion behaviour (radial and tangential) from the distortion center in 20 different directions as freely scalable graphs
• Representation as distorted grid
• Save the distortion data as profile dataset (ssv-table)
• Save the distortion data as grid dataset (ssv-table)

The graphical view enables to simply and fast estimate the extent and distribution of the distortion for all captured focal lengths.

The tabular output enables any desired data processing (comparison, control, archiving, etc.).

Vignetting

For each focal length and each f-stop exists one appropriate vignetting profile. The values are provided in two ways:

• Illumination fall-off behaviour from the center as freely scalable graph
• Save all profiles in a ssv-table
