Modifying an existing calibration
An existing calibration file can be loaded in Xeneth at the software level to recalibrate the
gain, offset or bad pixel maps, in a manner very similar to the creation of a new pack as
explained in Chapter 7.3.1. This is also done through the
Camera calibration wizard
.
Gain and offset recalibration occurs using the same wizard screens used for creating the
calibration in Chapter 7.3.1.
The
Bad pixel editor
provides a zoomed-in still view of the camera image, with a pixel grid
overlay. A moving box in the X-View pane indicates which area of the total frame the editor
is currently focused on, to keep an easy overview of where you are editing.
The example shown here is looking at a completely dark scene.
Pixels marked in purple (
1
) are currently marked as bad pixels.
Several unmarked pixels can be seen to show an incorrect response for the scene (
2
). To
mark these pixels as bad pixels, left click them. To remove a marked bad pixel, right click it.
Pressing the refresh button (
3
) updates the editor image with the latest acquired frame.
For more information on modifying an existing calibration file, please refer to the Xeneth User
Manual in the Xeneth installation folder.
