Screen Configuration <SDK for Polarization Camera XPL-SDKW>
■
Degree of Polarization (DoP)
The degree of polarization (DoP) is calculated for each pixel and displayed as a degree of
polarization image.
This feature makes it easier to see low-contrast objects or objects that are difficult to
recognize when they are the same color as the background.
■
Direction of Polarization (Surface Normal)
The plane direction is estimated from the polarized state of each pixel and displayed as a
surface normal image.
The object plane direction is divided into separate colors for an easy to differentiate display.
■
Retardation
This indicates the direction and whether or not there is any distortion when light passing
through the polarizing plate has passed through a transparent or semitransparent object.
The measurement is effective for checking the distortion when passing through transparent or
semitransparent objects such as glass and for checking stress.
■
Reflection (Enhance)
Reflected components calculated from four direction polarized images are enhanced.
Images reflected off transparent objects such as glass are enhanced when displayed.
A transparent object can also be made more visible.
■
Reflection (Cancel)
Reflected components calculated from four direction polarized images are removed.
Images reflected off transparent objects such as glass are reduced, making objects on the
other side more visible.
Reflections can be removed by both automatic calculation and manual angle adjustment.
■
Demosaic
Our unique demosaic function is optimally designed for the polarizer array.
All polarization processing on this SDK applies demosaic processing to calculate and display
images.
■
Online/offline support
Both online operation and offline operation are supported. Online displays images and
performs polarization processing live, and offline performs polarization processing when saved
image files are opened.
■
FFC (Flat Field Correction)
FFC processing uses two reference images (gray and dark) to make the brightness of the
recorded image uniform. Attach a lens to the polarization camera, capture gray and dark
images to save as calibration files, then load them when adjustments are necessary.
FFC processing can be used for post-processing without having to use the polarization
camera's shading correction.
