Horizontal Magnification

The Horizontal Magnification test gives the ratio between the horizontal size of the virtual image and the horizontal size of the warping.



Horizontal Magnification = Virtual image horizontal size / horizontal size

In detail:

For each sample EBij of the binocular eyebox, the Horizontal Magnification gives the ratio, virtual image horizontal size / warping horizontal size.

Virtual image horizontal size: For each sample EBij of the binocular eyebox, the virtual image horizontal size is the distance, in millimeter, from the middle left sample of the virtual image seen from the sample EBij of the binocular eyebox and projected on the target image to the middle right sample of the virtual image seen from the sample EBij of the binocular eyebox and projected on the target image.

Warping horizontal size: The warping horizontal size is the distance, in millimeter, from the middle left sample of the warping to the middle right sample of the warping.

Note: In the plugin, the dynamic distortion (the virtual image seen from the sample EBij) is computed in three dimensions.

The result of the computation is displayed as a table that contains the Horizontal Magnification computed for each sample EBij of the binocular eyebox.



In particular, you can notice that:
  • There is one table result by configuration created.
  • Each table has the size of the sampling of the binocular eyebox.
  • The test also displays a sum up, for each configuration, of the Average, the Standard deviation, the Minimum and the Maximum of the value contained in the table.
